FMKS-2152

Diode Arrays Overview

The FMKS-2152 is a fast recovery diode with built-in temperature detection, manufactured by Sanken Electric USA Inc. It integrates a fast recovery diode (FRD) and a Schottky barrier diode (SBD) on the same die to achieve highly accurate thermal monitoring. The FRD supports a peak repetitive reverse voltage of 200 V and an average forward current of 15 A. Key electrical parameters include a maximum forward voltage drop of 0.98 V at 15 A and a reverse recovery time of 50 ns. The device operates within a junction temperature range of -40 °C to 150 °C.

Diode Arrays Feature Summary

• Built-in temperature detection using a monolithic Schottky barrier diode for precise thermal monitoring
• High-speed switching capability with low forward voltage drop
• Component reduction by eliminating external thermistors from the thermal protection circuit

Diode Arrays Applications

• Audio equipment power supplies
• White goods control circuits
• General-purpose power supplies requiring thermal protection

Diode Arrays Procurement Notes

Verify component authenticity through official Sanken channels or authorized distributors. Confirm that the TO220F-3L package matches design requirements. Ensure compliance with RoHS directives and lead-free specifications. Review absolute maximum ratings carefully to prevent exceeding surge current limits during operation.

Diode Arrays Selection Notes

Select this component when integrated thermal sensing is required without adding discrete thermistors. The 15 A rating suits moderate power applications. Verify that the 200 V reverse voltage meets system isolation needs. Consider the 4.0 °C/W thermal resistance for heatsink calculations.

Diode Arrays Part Context

The FMKS series combines fast recovery diodes with temperature detection capabilities. This integration allows for real-time thermal monitoring directly from the semiconductor die. The technology replaces traditional thermistor-based solutions, enabling more compact designs and improved accuracy in power supply thermal management systems.

Diode Arrays FAQ

How does the FMKS-2152 detect temperature?

It uses the leakage current characteristics of an integrated Schottky barrier diode (SBD) formed on the same die as the fast recovery diode. As temperature rises, the SBD leakage current increases proportionally.

What is the maximum junction temperature?

The maximum operating junction temperature is 150 °C.

Can the FMKS-2152 replace a standard diode and thermistor combination?

Yes, it eliminates the need for an external thermistor by providing built-in temperature detection, reducing component count and improving thermal response accuracy.
