DMP21D1UTQ-13 Equivalent & Substitute Parts Reference Guide

Part Overview

DMP21D1UTQ-13 is a P-Channel MOSFET manufactured by Diodes Incorporated. It features a 20 V drain-to-source voltage (Vdss), 630 mA continuous drain current (Id), and 710 mOhm maximum Rds(on). The device supports gate voltages up to ±8 V, with an operating temperature range of -55°C to 150°C, and satisfies automotive grade qualification (AEC-Q101). The surface mount package is SOT-523, and compliant with ROHS3 and REACH. When inventory levels or sourcing constraints arise for DMP21D1UTQ-13, parametric equivalent models must match all key electrical, mechanical, and compliance specifications.

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on matching all key operating parameters for MOSFETs in this category. Primary criteria include drain-to-source voltage (Vdss), continuous drain current (Id @ 25°C), maximum Rds(on) at specified conditions, gate voltage ratings, package type (SOT-523), automotive qualification (AEC-Q101), compliance status, and product activity status. Only parametric equivalents fully matching the specified criteria are included.
