HER303G-TP

Single Diodes Overview

The HER303G-TP is a fast recovery rectifier diode manufactured by Micro Commercial Components (MCC). It features a single silicon element with a maximum average forward current of 3A and a repetitive peak reverse voltage of 200V. The device utilizes a glass passivated junction for high efficiency and reliability, housed in a DO-201AD through-hole package. Key electrical parameters include a maximum non-repetitive peak forward surge current of 125A, a typical reverse current of 10uA, and a fast recovery time of 50ns.

Single Diodes Feature Summary

• Glass passivated junction structure designed for high efficiency and reliability
• Fast recovery characteristics suitable for high-frequency switching applications
• High surge current capability to withstand transient overload conditions

Single Diodes Applications

• General purpose rectification in power supply circuits
• Freewheeling diodes in inductive load protection
• DC-DC converter output rectification

Single Diodes Procurement Notes

Verify the specific suffix and marking code on the component body to confirm it matches the HER303G-TP designation from MCC. Ensure the procurement documentation explicitly states the 200V rating and 3A current capacity, as these are critical for circuit compatibility. Confirm compliance with RoHS standards if required by the assembly specifications.

Single Diodes Selection Notes

Select this component when a 200V blocking voltage and 3A continuous current rating are required in a standard axial leaded package. The 50ns recovery time makes it suitable for higher frequency applications compared to standard rectifiers. Consider thermal management requirements based on the forward voltage drop at the expected operating current.

Single Diodes Part Context

This part belongs to the HER30xG series of high-efficiency rectifiers from Micro Commercial Components. The series covers various voltage ratings from 50V to 1000V while maintaining consistent current handling and package dimensions. The 'G' suffix typically denotes the glass passivation technology used in this product line.

Single Diodes Replacement Considerations

Direct replacements must match the 3A current, 200V voltage, and DO-201AD package. Verify that substitute parts offer equal or better reverse recovery time and surge current ratings to ensure circuit performance integrity.
