ES1CH Equivalent & Substitute Parts Engineering Reference

Part Overview

The ES1CH is a general-purpose surface mount rectifier diode manufactured by Taiwan Semiconductor Corporation. It is categorized under diodes, rectifiers, with a maximum reverse voltage of 150 V, forward current of 1 A, and a fast recovery time of 35 ns. The component is supplied in a DO-214AC (SMA) package and is AEC-Q101 qualified for automotive applications. The product has an active status and complies with ROHS3 and REACH requirements. Identifying electrically and mechanically equivalent substitute parts is necessary to ensure continuous production, inventory flexibility, and consistent quality assurance when original parts may not be available.

Key Parameters

Substitute Part Grouping Explanation

Parametric equivalents and substitutes are selected exclusively by matching critical electrical and mechanical parameters. These include maximum reverse voltage (Vr), average rectified current (Io), maximum forward voltage (Vf), reverse recovery time (trr), package/case, mounting type, qualification standards (automotive, AEC-Q101), RoHS and REACH compliance, and operating temperature range. Only parts within these boundaries are considered for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Selection between ES1CH and ES1C_R1_00001 can be based on matched electrical and mechanical parameters, product status, compliance with RoHS3, REACH, AEC-Q101 automotive qualification, and identical package types. Both listed devices maintain active manufacturing support, unlimited moisture sensitivity level, and standard packaging within the surface mount rectifier diode category.
