Product details

Overview

DMP22D4UFO-7B from Diodes Incorporated is a 20V P-channel enhancement-mode MOSFET in a 0.6mm × 0.4mm X2-DFN0604-3 package, featuring 1.9Ω R_DS(ON) at V_GS = −4.5V, −530mA continuous drain current, and a low gate threshold voltage of −1.0V max-designed for compact, high-efficiency power switching in portable battery management and load switching circuits.

For engineers reviewing the DMP22D4UFO-7B datasheet, DMP22D4UFO-7B pinout, DMP22D4UFO-7B application, or DMP22D4UFO-7B equivalent, key selection criteria include its ultra-low profile footprint, guaranteed AEC-Q101 qualification, sub-1V turn-on capability, and thermal resistance (R_θJA = 155°C/W on FR-4 with thermal bias) for space-constrained DC-DC and USB port protection designs.

Technical Context

This P-channel MOSFET operates as a single-polarity load switch with source-connected to supply rail and drain driving downstream circuitry. Its low V_GS(TH) (−0.4V to −1.0V) enables reliable turn-on from 1.8V logic, while integrated ESD protection (HBM >2kV) ensures robustness in handheld interfaces.

The device uses silicon process optimization to balance R_DS(ON) and gate charge (Q_g = 0.4nC), delivering fast switching (t_F = 16.4ns) with minimal Miller effect (C_rss = 2.9pF) - critical for low-noise, high-frequency power gating in always-on subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	−20V: Maximum reverse drain-source voltage before avalanche breakdown; supports 12V/15V rail switching with margin.
R_DS(ON)	1.9Ω @ V_GS = −4.5V: Enables <100mW conduction loss at 230mA, suitable for low-power load isolation.
I_D (max)	−530mA @ T_A = +25°C: Continuous current rating for steady-state operation on standard FR-4 PCBs.
V_GS(TH)	−1.0V max: Ensures full enhancement with 1.8V GPIO, eliminating need for level shifters in modern microcontrollers.
Q_g	0.4nC: Low total gate charge minimizes drive power and enables efficient PWM control at >1MHz.
R_θJA	155°C/W: Thermal resistance measured on 2oz copper FR-4 with thermal bias; defines safe power derating above ambient.
C_iss	28.7pF: Input capacitance determines gate drive strength requirement and impacts switching speed stability.

Pinout & Package

Package: X2-DFN0604-3 - ultra-thin (0.4mm height), 3-terminal leadless plastic package with exposed drain pad for thermal dissipation; footprint measures 0.60mm × 0.40mm with 0.30mm pitch.

Pin/Terminal	Circuit Role	Design Meaning

Gate (G)	Control input	High-impedance terminal requiring <10μA leakage; protected by integrated ESD diode to S and D.

Key Features

Feature	Design Value
Ultra-low gate threshold	V_GS(TH) ≤ −1.0V enables direct interface with 1.8V I/O without level translation.
Miniature footprint	0.6mm × 0.4mm area reduces board space by >60% vs. SOT-23, critical for wearables and TWS earbuds.
ESD-protected gate	HBM >2kV rating eliminates external TVS requirements in consumer-grade USB and audio switch applications.
AEC-Q101 qualified	Validated for automotive body electronics including mirror folding, LED status indicators, and sensor power gating.
Green RoHS compliance	Halogen- and antimony-free molding compound meets JESD204B and IPC-1752a environmental reporting standards.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel load switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2020LFG-7	R_DS(ON) = 2.2Ω @ −4.5V; larger 1.0mm × 0.6mm package; higher Q_g (0.6nC)	Higher thermal mass suits higher-current (800mA) loads but requires more PCB area	Select when higher current headroom and less stringent size constraints exist
AO3401	R_DS(ON) = 45mΩ @ −4.5V; SO-23 package; V_GS(TH) = −0.7V to −1.3V; no AEC-Q101 rating	Lower R_DS(ON) supports higher currents but lacks automotive qualification and miniaturization	Select for cost-sensitive industrial applications where AEC-Q101 and 0.6×0.4mm footprint are not required

Compared with DMN2020LFG-7 and AO3401, DMP22D4UFO-7B uniquely combines AEC-Q101 qualification, 0.6mm × 0.4mm footprint, and sub-1V threshold in a single device-making it optimal for space-limited automotive and portable electronics where reliability and size are co-constrained.

FAQ

What is the maximum continuous drain current for DMP22D4UFO-7B at 85°C ambient?

The maximum continuous drain current is −383mA at T_A = +85°C, as specified in the Absolute Maximum Ratings table. This derating accounts for reduced thermal dissipation on standard FR-4 PCBs without additional heatsinking or airflow.

Does DMP22D4UFO-7B require an external gate resistor for stable switching?

No external gate resistor is required for basic on/off switching due to its low Q_g (0.4nC) and integrated gate protection. However, a 10–100Ω series resistor is recommended when driving from high-impedance sources to damp ringing and reduce EMI in high-frequency PWM applications.

Can DMP22D4UFO-7B be used in linear regulation mode?

No-it is not characterized or rated for linear (ohmic) operation. The Safe Operating Area (SOA) curve shows only pulsed operation up to 10ms; sustained linear use risks thermal runaway due to lack of SOA derating data and undefined thermal impedance under DC bias.

Is the exposed drain pad electrically connected to the drain terminal?

Yes-the exposed metal pad on the bottom of the X2-DFN0604-3 package is internally connected to the drain terminal and serves as the primary thermal and electrical path. It must be soldered to a PCB copper pour tied to the drain net for both thermal performance and electrical integrity.
