Diodes Incorporated DMPH6050SSDQ-13

Overview

DMPH6050SSDQ from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET rated for -60V V_DSS, 48 mΩ R_DS(ON) @ V_GS = -10V, and continuous drain current of -5.2 A at +25°C. It features AEC-Q101 qualification, 175°C maximum junction temperature, and SO-8 package - designed for high-reliability automotive power switching in engine management and body control modules.

For engineers reviewing the DMPH6050SSDQ datasheet, DMPH6050SSDQ pinout, DMPH6050SSDQ application, or DMPH6050SSDQ equivalent, key selection criteria include its dual P-channel topology, low gate charge (14.5 nC @ V_GS = -4.5V), 100% unclamped inductive switching rating, and thermal robustness up to +175°C in automotive under-hood environments.

Technical Context

This dual P-channel MOSFET integrates two matched, isolated power switches in a single SO-8 package with shared thermal path and independent gate terminals. Its design supports synchronous buck topologies, high-side load switching, and reverse polarity protection where bidirectional blocking and low conduction loss are required.

The device delivers stable R_DS(ON) across -55°C to +175°C (normalized variation <2.2× at V_GS = -10V), exhibits low Q_gd/Q_g ratio (5.2/30.6 nC) for fast turn-off, and maintains <1.2 V diode forward voltage at -1 A - enabling efficient body-diode conduction during dead-time intervals.

FAQ

What is the maximum continuous drain current for each channel at +100°C ambient?

At TA = +100°C, the maximum continuous drain current per channel is -3.7 A when mounted on FR-4 with 2 oz copper and thermal bias to a 1-inch square copper plate (per Note 7). This reflects thermal derating from the +25°C rating of -5.2 A, based on R_θJA = 75°C/W and T_J(max) = +175°C.

Does DMPH6050SSDQ support parallel operation of both channels for higher current handling?

No - the device is not characterized for paralleling channels due to mismatch in R_DS(ON) (±20% typical), gate threshold voltage (±1.0 V), and thermal coupling limitations. Each channel must be driven independently with separate gate resistors and layout symmetry to avoid current imbalance and thermal runaway.

What is the significance of the "100% UIS tested" specification?

Every unit undergoes unclamped inductive switching stress testing at I_AS = -25 A and E_AS = 33 mJ, verifying robustness against inductive energy stored in solenoids, relays, and motors. This eliminates field failures from voltage overshoot during turn-off without external clamping components.

Can this MOSFET be used in linear regulation mode?

It is not recommended for sustained linear operation due to limited safe operating area (SOA) at high V_DS and low current: maximum DC power dissipation is 2.0 W at +25°C ambient, and R_θJA rises sharply above 100°C, risking thermal instability without active cooling and precise gate bias control.
