S1DHE3/5AT

Single Diodes Overview

The S1DHE3/5AT is a standard rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage of 200 V. The device utilizes a DO-214AC (SMA) surface-mount package. Key electrical parameters include a maximum DC forward voltage drop of 1.1 V at 1 A and a maximum non-repetitive peak forward surge current of 30 A for an 8.3 ms half-sine wave. Operating junction temperature ranges from -55°C to +150°C, with a maximum reverse leakage current of 1 µA at 200 V.

Single Diodes Feature Summary

• High thermal stability with a junction temperature rating up to 150°C
• Low forward voltage drop for improved efficiency
• Plastic material compliant with UL 94 V-0 flammability ratings
• Mechanical shock and vibration resistance

Single Diodes Applications

• General purpose rectification in power supplies
• Freewheeling diodes in converters and inverters
• Consumer electronics circuit protection
• Automotive electronic modules
• Telecommunication equipment

Single Diodes Procurement Notes

Verify the specific suffix '5AT' corresponds to the required tape-and-reel packaging configuration when ordering. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as these details are subject to change based on production schedules and regional availability.

Single Diodes Selection Notes

Select this component for applications requiring a compact SMA package with 1 A current handling capability. Ensure the circuit's reverse voltage does not exceed 200 V and that thermal management supports operation up to 150°C junction temperature. Compare against similar SMA rectifiers if higher current or voltage ratings are needed.

Single Diodes Part Context

This part belongs to the Vishay SMA series of general-purpose silicon rectifiers. The HE3 designation indicates the use of Vishay's Hyperfast III technology, which offers superior switching characteristics compared to standard P-type silicon diodes. The S1D variant specifically denotes the 200 V blocking voltage within this product line.

Single Diodes Replacement Considerations

Direct substitutes include other SMA-package 200 V 1 A rectifiers such as the 1N5819 equivalent in SMA format or parts from the same Vishay SMA family like S1J or S1G, provided voltage ratings meet or exceed requirements.
