HER101G-TP

Single Diodes Overview

The HER101G-TP is a glass-passivated high-efficiency rectifier diode manufactured by Micro Commercial Components (MCC). It features a single silicon element housed in a DO-201AD axial leaded package. The device supports an average forward current of 1A and offers repetitive peak reverse voltage ratings ranging from 50V to 1000V, with the specific '1' suffix indicating a 50V rating. Key electrical parameters include a maximum non-repetitive peak forward surge current of 30A at 60Hz sine wave half-cycle, a maximum DC blocking leakage current of 5µA at rated voltage, and a typical junction capacitance of 80pF at 4V reverse bias. The component operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Glass passivation provides mechanical strength and meets UL flammability classification 94V-0 for the epoxy encapsulant.
• High efficiency design ensures low forward voltage drop and high reliability under operating conditions.
• Capable of handling high surge currents suitable for general-purpose rectification applications.

Single Diodes Applications

• General purpose rectification in power supply circuits
• Bridge rectifier configurations
• Freewheeling diodes in inductive load switching

Single Diodes Procurement Notes

Verify the specific voltage sub-rating corresponding to the suffix code, as the series spans 50V to 1000V. Confirm compliance with RoHS directives and REACH regulations prior to integration. Check for Halogen-free availability if required by specific environmental standards. Ensure the DO-201AD package dimensions match the target PCB footprint. Validate that the thermal management strategy accommodates the specified junction temperature limits.

Single Diodes Selection Notes

Select this component for through-hole designs requiring robust glass-passivated protection against moisture and mechanical stress. The 1A current rating suits low-to-medium power applications where standard recovery characteristics are sufficient. Consider the wide operating temperature range for environments subject to thermal cycling. Compare leakage current specifications against sensitive circuit requirements to ensure minimal standby power loss.

Single Diodes Part Context

This part belongs to the HER101G-HER308G family of high-efficiency rectifiers from MCC. The series utilizes glass passivation technology to enhance durability compared to standard plastic-encapsulated diodes. The HER101G variant specifically denotes the 50V rating within this lineup, sharing common packaging and general performance traits with higher voltage siblings like the HER102G or HER103G.

Single Diodes Replacement Considerations

Direct substitutes must match the 1A current, 50V reverse voltage, and DO-201AD package. Verify that alternative components maintain similar glass passivation benefits and surge current capabilities to ensure equivalent reliability in existing designs.
