ESH3CHE3/9AT

Single Diodes Overview

The ESH3CHE3/9AT is a single silicon rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 150 V and an average forward rectified current (Io) of 3 A. The device is housed in a DO-214AB (SMC) surface-mount package. Key electrical parameters include a maximum forward voltage (Vf) of 900 mV at 3 A, a reverse leakage current of 5 µA at 150 V, and a reverse recovery time (trr) of 40 ns. The junction capacitance is 70 pF at 4 V and 1 MHz. The component operates within a junction temperature range of -55°C to 175°C.

Single Diodes Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm compliance with RoHS3 standards and lead-free specifications. Confirm that the ordering part number matches the required package type and qualification status. Ensure compatibility with J-STD-020 moisture sensitivity level 1 requirements during assembly processes involving lead-free soldering peaks up to 260 °C.

Single Diodes Selection Notes

Select this component for designs requiring a 150 V rated surface-mount rectifier with high thermal stability up to 175°C junction temperature. The 40 ns reverse recovery time makes it suitable for general-purpose switching applications where moderate speed is sufficient. Consider the SMC package dimensions for PCB layout constraints and verify that the 3 A continuous current rating aligns with the circuit's peak load requirements.

Single Diodes Part Context

This component belongs to the ESH3 series of glass passivated rectifiers from Vishay. The series is characterized by its robust construction and suitability for automated manufacturing processes. The ESH3CHE3/9AT variant specifically denotes the 150 V version within this family, sharing common features such as AEC-Q101 automotive qualification and compliance with environmental directives.

Single Diodes Replacement Considerations

Direct substitutes may include other 150 V, 3 A SMC rectifiers from Vishay or equivalent manufacturers. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference datasheets to ensure matching reverse recovery times and forward voltage drops for identical performance.
