Sanken’s groundbreaking FMKS-2152 (FMKS) is a diode array designed to transform temperature detection in electrical circuits. Since temperature detection is crucial for ensuring the optimal functioning of circuitry, a device like FMKS can be borderline groundbreaking.
This tool is a fast recovery diode with built-in temperature detection. Its unique structure combines a quick recovery diode and a Schottky barrier diode on the same die, achieving highly accurate temperature detection that surpasses traditional methods.
This comprehensive article breaks down the FMKS technical specifications and features and showcases its versatility in application.
Key FMKS-2152 Features
The FMKS reflects continuous innovation in electrical engineering, boasting features that redefine circuit temperature detection. One of its key attributes is the integration of a fast recovery diode (FRD) and a Schottky barrier diode (SBD) on the same die, ensuring that temperature detection is highly accurate and real-time. That provides engineers with a dynamic tool for monitoring circuit conditions.
The FRD component of the FMKS contributes to high-speed switching, maintaining efficiency in electrical systems. With an average rectified current of 15A and a maximum reverse voltage of 200V, this diode array is well-equipped to handle the demands of modern circuits. Moreover, the reverse recovery time of 35 nanoseconds solidifies its position as a responsive and reliable component. FMKS also has a forward voltage drop of 0.98V, enabling minimal energy loss during operation. That
efficiency level is essential for applications ranging from audio systems to power supplies, where energy conservation comes first.
FMKS Advantages in Electrical Networks
The FMKS series reduces component count, especially in temperature detection circuits, nearly creating a paradigm shift in circuit design. By incorporating FRD and SBD in a single package, it eliminates the need for additional components, such as thermistors.
This feature simplifies the circuitry and reinforces power supply downsizing. Moreover, the FMKS series has high-speed switching capabilities, allowing it to maintain optimal performance in electrical networks.
With a surge forward current of 100A and a reverse recovery time of 35 nanoseconds, the FMKS-2152 ensures swift and efficient responses to the network’s dynamic changes.
FMKS Series Products and Applications
Although it covers a broad spectrum of applications, the FMKS series is a go-to choice for professionals in audio systems, white goods, and power supplies. Its adaptability stems from its integration into circuits equipped with thermal protection and peak power limiting mechanisms, making it an indispensable component in these industries.
The FMKS-2152, operating at a peak reverse voltage (VRM) of 200V and an average forward current (IF) of 15A, stands out as a reliable and efficient fast recovery diode (FRD) with built-in temperature detection. This combination of attributes makes it a preferred choice in applications demanding high-speed switching and precise temperature monitoring.
For instance, the FMKS series ensures optimal performance in audio systems by swiftly responding to dynamic changes in electrical currents. Meanwhile, in white goods, its highly accurate temperature detection capabilities contribute to the safety and reliability of the overall system. Thanks to the integrated temperature detection mechanism, power supplies benefit from the FMKS series by achieving enhanced efficiency and downsized designs.
Temperature Detection Application of FMKS Series
The FMKS temperature detection application mirrors its innovative design and practical benefits in electrical circuits.
For example, in traditional setups, a secondary rectifier diode in off-line flyback converters relies on a temperature detection circuit involving a Negative Temperature Coefficient (NTC) thermistor. However, the FMKS series introduces a more advanced and efficient alternative.
It also comes with real-time temperature detection of the FRD, contributing to a more responsive and adaptive system. The use of SBD for temperature detection leverages the temperature-dependent characteristics of its leakage current, allowing for precise monitoring even in challenging conditions.
This application offers several advantages, including highly accurate and stable temperature detection of the FRD, component reduction compared to traditional thermistors, and simplified power supply designs. As a result, the FMKS series is an efficient solution for professionals seeking advanced temperature monitoring capabilities in their wiring configurations.
FMKS Installation and Maintenance Tips
Here are a few tips on installing and maintaining your FMKS diode.
Be Precise
Mount the FMKS series diodes using the Through Hole TO-220-3 packaging. Precision in attachment is crucial for their efficient operation. However, we advise following the guidelines outlined in the datasheet when aligning the diodes with the electrical circuit to ensure a secure and reliable connection.
Crimp and Fasten
Leverage appropriate crimping tools for the Through Hole mounting, ensuring a snug fit. That will help establish stable connections and enable accurate temperature detection and overall electrical network reliability.
But always adhere to the recommended crimping specifications to maintain optimal performance.
Occasionally Check Your FMKS Diode
When checking your FMKS diodes, focus on the physical integrity of the diodes and the surrounding components. Any deviations from the specified conditions might compromise their functionality.
Leverage Catalog Number Reference
Take advantage of the catalog number stamped on the diodes for permanent identification. This reference simplifies maintenance procedures, streamlining routine checks or replacements.
Make Use of Insulation Options
Consider additional insulation options, such as molded rubber boots or heat-shrinkable tubing, to protect the FMKS series during installation and operation. These options safeguard the diodes from external elements and reinforce durability.
Sanken’s FMKS series is an innovative solution for precise temperature detection in electrical circuits. Thanks to its robust features, including a 200V max reverse voltage and adherence to stringent safety standards, FMKS ensures reliable performance.
