HER308-TP

Single Diodes Overview

The HER308-TP is a high-efficiency rectifier from the HER301 through HER308 series manufactured by Micro Commercial Components. It features a maximum repetitive peak reverse voltage of 1000V and an average forward current rating of 3.0A at 55°C. The device exhibits a maximum instantaneous forward voltage of 1.7V at 3.0A and a typical junction capacitance of 50pF. Maximum DC reverse current is specified as 200µA at 100°C. It utilizes a DO-201AD axial leaded package with a typical thermal resistance of 30°C/W.

Single Diodes Feature Summary

• High surge current capability for robust operation
• Low forward voltage drop to minimize energy losses
• Epoxy encapsulation meets UL 94 V-0 flammability rating

Single Diodes Applications

• General purpose rectification in power supplies
• Bridge rectifiers for AC to DC conversion
• Free-wheeling diodes in inductive load circuits

Single Diodes Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to ensure traceability and quality standards. Confirm the specific suffix requirements, such as -HF for halogen-free versions, match project specifications. Check datasheet revision dates for updated electrical characteristics before finalizing component selection.

Single Diodes Selection Notes

Select this component when a 1000V blocking voltage and 3A continuous current are required in an axial package. Consider the 75ns reverse recovery time for switching applications. Ensure ambient temperature derating curves are analyzed if operating conditions exceed standard ratings. Verify lead length dimensions fit the target PCB layout constraints.

Single Diodes Part Context

This part belongs to the HER30xG series of fast recovery rectifiers designed for high efficiency. It shares the same physical DO-201AD footprint and general electrical architecture as lower voltage variants like the HER301 through HER307, differing primarily in breakdown voltage and associated leakage parameters.

Single Diodes Replacement Considerations

Direct substitutes include other 1000V 3A axial rectifiers in the DO-201AD package. Verify that replacement parts meet the 1.7V forward voltage and 75ns reverse recovery time specifications to maintain circuit performance equivalence.
