HER105-TP

Single Diodes Overview

The HER105-TP is a 1.0 Amp high-efficiency rectifier from the HER101-HER108 series, manufactured by Micro Commercial Components (MCC). It features a maximum recurrent peak reverse voltage of 400V and a maximum DC blocking voltage of 400V. The device utilizes a DO-41 axial leaded package with a glass passivated junction. Key electrical parameters include a maximum instantaneous forward voltage of 1.3V at 1.0A and a typical junction capacitance of 20pF. It supports an operating temperature range of -55°C to +125°C and offers a peak forward surge current capability of 30A.

Single Diodes Feature Summary

• Low forward voltage drop for improved efficiency
• Glass passivated junction ensuring reliability under harsh conditions

Single Diodes Applications

• General purpose rectification in power supplies
• Freewheeling diodes in inductive load circuits
• Reverse polarity protection in electronic systems

Single Diodes Procurement Notes

Verify authenticity through authorized MCC distributors or direct procurement channels to avoid counterfeit components. Confirm the specific suffix (e.g., -TP for tape and reel) matches the required packaging format. Ensure compliance with RoHS standards if applicable, noting that standard parts are lead-free finish compliant while halogen-free options require the -HF suffix. Review the manufacturer's life support disclaimer before critical application deployment.

Single Diodes Selection Notes

Select the HER105-TP when a 400V reverse voltage rating is required for 1.0A continuous applications. Consider the 1.3V forward voltage drop for thermal management calculations. Evaluate the 50ns reverse recovery time against switching frequency requirements. Compare against lower voltage variants like HER104 or higher voltage variants like HER106 based on circuit peak inverse voltage demands.

Single Diodes Part Context

This component belongs to the HER101 through HER108 family of high-efficiency rectifiers. All members share the same 1.0A average forward current rating and DO-41 package but differ in their voltage ratings ranging from 50V to 1000V. The HER105 specifically targets 400V applications within this standardized lineup, offering consistent performance characteristics across the series.

Single Diodes Replacement Considerations

Direct substitutes within the same voltage class include other manufacturers' 1A 400V rectifiers in DO-41 packages. Verify pinout compatibility and ensure equivalent or superior electrical parameters for forward voltage, reverse leakage, and surge current capacity.
