ESH3DH

Single Diodes Overview

The ESH3DH is a surface mount ultra-fast rectifier manufactured by Taiwan Semiconductor Corporation. It features a single diode configuration housed in a DO-214AB (SMC) package. The device supports an average forward current of 3 A and offers reverse voltage ratings ranging from 100 V to 200 V, with the specific 'H' suffix typically denoting a 200 V rating. Key electrical characteristics include a maximum surge current of 125 A, a typical forward voltage of 0.9 V, and a reverse leakage current of 5 uA. The component operates within a junction temperature range of -55 °C to +175 °C and exhibits an ultra-fast recovery time of 20 ns.

Single Diodes Applications

• High frequency rectification
• Freewheeling applications
• Switching mode converters and inverters

Single Diodes Procurement Notes

Verify the exact reverse voltage rating associated with the 'H' suffix against the manufacturer's official datasheet, as the series spans multiple voltage options. Confirm compliance with RoHS Directive 2011/65/EU and WEEE 2002/96/EC requirements. Ensure the DO-214AB package dimensions match the target PCB layout constraints before finalizing procurement.

Single Diodes Selection Notes

Select this component for circuits requiring fast switching speeds and high thermal stability. The 20 ns recovery time makes it suitable for high-frequency operations where standard rectifiers would incur excessive losses. Verify that the 3 A forward current capacity meets the load requirements and that the 200 V reverse voltage provides adequate margin for the circuit's peak inverse voltage.

Single Diodes Part Context

This part belongs to the ESH3B through ESH3D series of surface mount ultra-fast rectifiers. The series is characterized by its glass passivated junction technology and low-profile SMC packaging. These components are engineered to replace bulkier axial leaded diodes in modern compact electronic designs while maintaining robust performance under high-temperature conditions.

Single Diodes Replacement Considerations

Direct substitutes within the same series include ESH3BH (100V) or ESH3CH (150V) if lower voltage ratings are acceptable. Cross-brand equivalents must be verified for identical DO-214AB footprint, 3A current rating, and 20ns recovery time specifications.
