ES1ALHMQG Equivalent & Substitute Parts Reference

Part Overview

The ES1ALHMQG by Taiwan Semiconductor Corporation is a fast recovery, general-purpose rectifier diode designed for automotive applications. It operates up to 50 V reverse voltage and 1 A average rectified current in a surface mount Sub SMA (DO-219AB) package. The device is ROHS3 Compliant, AEC-Q101 qualified, and has an operating junction temperature range of -55°C to 150°C. Sourcing equivalent models ensures continuity of supply, aids in lifecycle management, and maintains production schedules in case of inventory shortages or supply chain disruptions.

Substitute Part Grouping Explanation

Substitution is determined exclusively by matching the following parameters: maximum reverse voltage (Vr), average rectified current (Io), forward voltage (Vf) at specified current, speed classification, reverse recovery time (trr), maximum reverse leakage current, capacitance, mounting type, package/case, operating temperature range, RoHS status, MSL, REACH status, and compliance with automotive qualifications if specified. Only components satisfying these parameters qualify as substitutes for the ES1ALHMQG in the Diodes, Rectifiers category.
