Diodes Incorporated DMP22D5UDJ-7A

Overview

DMP22D5UDJ-7A from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in an ultra-small SOT963 package, designed for low-voltage power switching with R_DS(ON) as low as 1.0 Ω at V_GS = −4.5 V, −0.36 A continuous drain current, and gate threshold voltage ≤ −1.0 V. It serves as a compact load switch or analog switch in space-constrained portable electronics.

For engineers reviewing the DMP22D5UDJ-7A datasheet, DMP22D5UDJ-7A pinout, DMP22D5UDJ-7A application, or DMP22D5UDJ-7A equivalent, key selection criteria include its 1 mm × 1 mm footprint, low 1.9 Ω R_DS(ON) at −4.5 V, ESD-protected gate, and suitability for battery-powered signal routing and power domain isolation.

Technical Context

This dual P-channel MOSFET integrates two independent enhancement-mode transistors sharing no internal connection-each with separate source, drain, and gate terminals. Its low V_GS(TH) (−0.4 to −1.0 V) enables reliable turn-on from 1.8 V logic, while low C_iss (17 pF) and fast switching (t_D(ON) = 7.3 ns) support high-frequency control in DC-DC bias sequencing and USB port power management.

The device operates across −55 °C to +150 °C junction temperature, with R_DS(ON) normalized variation <1.3× over that range at V_GS = −1.0 V. Thermal resistance R_θJA is 330 °C/W on FR-4 PCB with minimum pad layout, limiting steady-state power dissipation to 0.38 W.

FAQ

What is the maximum continuous drain current for each channel of DMP22D5UDJ-7A at +70°C ambient?

At T_A = +70°C, the maximum continuous drain current per channel is −0.29 A, as specified in the Absolute Maximum Ratings table. This derating accounts for thermal limitations on standard FR-4 PCB with minimum recommended pad layout, and assumes no forced airflow or heatsinking.

Does DMP22D5UDJ-7A have internally connected sources or drains between the two channels?

No. The two P-channel MOSFETs are fully independent: pins 2 (S1) and 5 (S2) are separate source terminals, and pins 3 (D1) and 4 (D2) are separate drain terminals. There is no internal connection between channels-confirmed by the Equivalent Circuit diagram and pinout definition in the datasheet.

Can DMP22D5UDJ-7A be used in automotive applications?

DMP22D5UDJ-7A is not AEC-Q101 qualified. While it operates across −55°C to +150°C junction temperature, Diodes explicitly states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing-none of which apply to this standard commercial-grade part.

What is the significance of the "-7A" suffix in DMP22D5UDJ-7A?

The "-7A" suffix indicates tape-and-reel packaging with a Pin 1 indicator mark on the device body. Per datasheet Note 6, this marking aids automated placement verification but confers no electrical or functional difference versus the -7 variant-both share identical specifications, reliability, and thermal performance.
