APT15S20KG

Overview

The APT15S20KG is a high voltage Schottky diode manufactured by Microsemi Corporation, designed for efficient power conversion applications. It features a maximum DC reverse voltage of 200 V and a continuous forward current rating of 25 A at a case temperature of 122°C. The device utilizes a TO-220 (K) through-hole package with a cathode-back configuration. Key electrical characteristics include a typical forward voltage of 0.83 V at 15 A and a maximum reverse leakage current of 75 mA at rated voltage. Dynamic performance includes a reverse recovery time of 8 ns under standard test conditions.

Feature Summary

• Ultrafast recovery times with soft recovery characteristics to minimize switching noise
• Low forward voltage drop for reduced conduction losses and cooler operation
• High blocking voltage capability with low leakage current for improved reliability

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 ordering suffix 'KG' against the manufacturer's official documentation to confirm package variant and compliance status. Confirm availability as product lifecycle status may vary. Ensure thermal management design accounts for junction-to-case resistance values specified in the datasheet. Validate that the TO-220 (K) pinout matches the system schematic requirements before integration.

Selection Notes

Select this component for applications requiring fast switching speeds and low reverse recovery charge to enhance system efficiency. The 200 V rating suits low-voltage high-current power stages. Consider the TO-220 (K) package for through-hole mounting constraints. Evaluate thermal performance based on the specified junction-to-case thermal resistance and expected duty cycles in the target application environment.
