HER304-TP

Single Diodes Overview

The HER304-TP is a 3.0 Amp high-efficiency rectifier from the HER301–HER308 series by Micro Commercial Components, housed in a DO-201AD package. It features a maximum repetitive peak reverse voltage of 300V and a maximum DC blocking voltage of 300V. The device supports an average forward current of 3.0A at 55°C ambient temperature with a peak forward surge current capability of 150A for 8.3ms half-sine waves. Electrical characteristics include a maximum instantaneous forward voltage of 1.3V at 3.0A and 25°C, a maximum DC reverse current of 10µA at rated voltage (25°C), and a typical junction capacitance of 80pF measured at 1.0MHz.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify authenticity through authorized distributors to avoid counterfeits. Confirm RoHS compliance status via ordering suffixes; standard parts are lead-free finish compliant. Check for halogen-free availability if required by adding the -HF suffix. Ensure storage conditions align with MSL 1 requirements. Review manufacturer's life support disclaimer before critical deployment.

Single Diodes Selection Notes

Select based on reverse voltage requirements; HER304 offers 300V blocking suitable for 220V AC mains rectification. Consider thermal derating curves for ambient temperatures above 55°C. Compare forward voltage drop against other series members for efficiency optimization. Verify package compatibility with existing PCB footprints for DO-201AD components.

Single Diodes Part Context

Part of the HER301 through HER308 family of 3.0A high-efficiency rectifiers. Shares common mechanical dimensions and thermal characteristics within the series. Designed for general-purpose switching applications requiring fast recovery times compared to standard rectifiers. Manufactured by Micro Commercial Components Corp.

Single Diodes Replacement Considerations

Direct substitutes within the same series include HER301, HER302, HER303, HER305, HER306, HER307, and HER308, provided voltage ratings meet circuit requirements. Cross-brand replacements must match 3.0A current, 300V reverse voltage, and DO-201AD package constraints.
