ES1CHE3_A/H

Single Diodes Overview

The ES1CHE3_A/H is a single ultra-fast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 150 V and an average forward rectified current of 1 A. The device exhibits a typical forward voltage of 920 mV at 1 A and a maximum reverse leakage current of 5 uA at 150 V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 30 A and a fast recovery time of 15 ns. It operates within a junction temperature range of -55 °C to +150 °C.

Single Diodes Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact packaging configuration, as ordering codes may denote variations in reel or cut-tape quantities. Ensure the component meets RoHS directives and SVHC requirements relevant to your manufacturing region. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and lead times before finalizing procurement plans.

Single Diodes Selection Notes

Select this component when circuit design requires a compact SMA package with ultra-fast recovery characteristics. The 150 V rating suits low-voltage DC-DC converters and general-purpose rectification. Consider the 1 A current limit and thermal management capabilities during PCB layout. Verify that the 15 ns recovery time aligns with the switching frequency requirements of the target application to minimize switching losses.

Single Diodes Part Context

This device belongs to the ES1C series of ultra-fast recovery rectifiers from Vishay. The series is engineered for efficiency in modern power conversion topologies. The ESH3CHE3_A/H variant shares similar packaging but differs in voltage and current ratings. The ES1CHE3_A/H specifically targets applications needing faster recovery than standard rectifiers while maintaining robustness in small form factors.

Single Diodes Replacement Considerations

Consult official Vishay substitution guides for verified equivalents. Generic replacements must match the 150 V reverse voltage, 1 A forward current, and DO-214AC package dimensions. Verify that substitute components meet the same AEC-Q101 qualification if automotive reliability is required.
