APT15S20KCTG

Overview

The APT15S20KCTG is a high voltage Schottky diode manufactured by Microsemi Corporation. It features a dual common cathode configuration housed in a TO-220 package. The device supports a maximum DC reverse voltage of 200V and a peak repetitive reverse voltage of 25V per leg. Each leg provides a maximum average forward current of 15A at a case temperature of 122°C with a 0.5 duty cycle. The junction-to-case thermal resistance is typically 1.1 °C/W, and the operating junction temperature range spans from -55°C to 150°C.

Feature Summary

• Ultrafast recovery times with soft recovery characteristics for reduced noise
• Low forward voltage and low leakage current for efficient operation
• Dual common cathode design within a standard TO-220 package

Applications

• Parallel diodes in switchmode power supplies and inverters
• Free wheeling diodes in motor controllers and converters
• Snubber diodes in high-speed rectifier circuits
• Uninterruptible power supply (UPS) systems
• 48 Volt output rectifiers

Procurement Notes

Verify the specific suffix 'G' against official documentation to confirm compliance status or material composition changes. Confirm availability as this component may be subject to discontinuation notices. Ensure the TO-220 package outline matches your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring fast switching speeds and low reverse recovery charge. Evaluate the thermal management strategy based on the 1.1 °C/W junction-to-case resistance. Consider the 200V blocking capability and 15A continuous current rating relative to the expected load conditions and ambient temperatures.

Part Context

This part belongs to the APT series of high voltage Schottky diodes designed for power conversion efficiency. It utilizes silicon technology to deliver superior performance compared to standard rectifiers. The dual-leg configuration allows for compact circuit designs in bridge or parallel arrangements.
