SK17E3/TR13

Single Diodes Overview

The SK17E3/TR13 is a Schottky barrier rectifier manufactured by Microsemi Corporation. It features a single diode element constructed from silicon and housed in the DO-214AA (SMB) surface-mount package. The device has a maximum repetitive peak reverse voltage of 70V and an average forward rectified current rating of 1A. It exhibits a maximum reverse leakage current of 500µA at 70V and operates within a junction temperature range of -65°C to 175°C.

Single Diodes Feature Summary

• Schottky barrier construction for low forward voltage drop
• Guard ring protection for enhanced stability
• Extremely low thermal resistance characteristics
• Reverse energy tested for reliability

Single Diodes Applications

• General-purpose rectification in surface-mount circuits
• Power supply input stages requiring low loss
• DC-DC converter freewheeling applications

Single Diodes Procurement Notes

Verify the manufacturer designation as Microsemi or its successor entity, Microchip Technology, on the component marking. Confirm the DO-214AA package outline matches design requirements. Ensure the suffix TR13 corresponds to the specified reel packaging format required for automated assembly processes.

Single Diodes Selection Notes

Select this component when a 70V reverse voltage rating and 1A continuous current capability are required in a compact SMB package. Consider the low forward voltage characteristic for efficiency optimization. Verify that the 175°C maximum junction temperature meets the thermal management constraints of the target application environment.

Single Diodes Part Context

This part belongs to the SK series of 1 Amp Schottky Rectifiers offered by Microsemi. The series covers voltage ratings from 20V to 100V in the DO-214AA package. These devices are designed for high-efficiency rectification where low power loss and fast switching speeds are critical performance factors.
