Product details

Overview

DMP2070UQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET designed for load switching in space-constrained, low-voltage power rails. It delivers 44 mΩ R_DS(ON) at V_GS = −4.5 V, supports −4.6 A continuous drain current, features ESD-protected gate, and is qualified to AEC-Q101 for automotive use - deployed in USB port power control and battery backup circuits.

For engineers reviewing the DMP2070UQ datasheet, DMP2070UQ pinout, DMP2070UQ application, or DMP2070UQ equivalent, key selection criteria include low-threshold gate drive compatibility (V_GS(TH) = −0.45 to −0.95 V), thermal performance on FR-4 (R_θJA = 153 °C/W), and SOT23 footprint suitability for high-density PCB layouts.

Technical Context

This MOSFET operates as a high-side load switch with logic-level gate drive capability, enabling direct interface with 3.3 V or 5 V microcontroller GPIOs without level-shifting. Its −20 V V_DSS rating and low input capacitance (C_iss = 118 pF) support fast turn-on/turn-off transitions (t_D(ON) = 115 ns, t_F = 666 ns) while minimizing switching losses.

The device integrates an ESD-protected gate structure and exhibits low body diode forward voltage (V_SD = −0.7 to −1.1 V at −2.1 A), supporting bidirectional current handling in reverse-polarity protection and OR-ing applications. Its R_DS(ON) remains stable across −55 °C to +150 °C junction temperature range, with <15% variation at V_GS = −1.8 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	−20 V - Supports rail voltages up to 18 V with margin for transients in automotive and industrial 12 V systems.
R_DS(ON) @ V_GS = −4.5 V	44 mΩ max - Enables ≤200 mW conduction loss at −2 A, critical for thermally limited SOT23 packages.
I_D Continuous	−4.6 A @ T_C = +25°C - Rated for sustained load switching in compact DC-DC output stages and hot-swap circuits.
V_GS(TH)	−0.45 to −0.95 V - Ensures reliable turn-on with standard 3.3 V logic outputs, eliminating need for gate driver ICs.
C_iss	118 pF - Low input capacitance reduces gate drive power and improves switching speed in high-frequency PWM control.
Q_g @ V_GS = −4.5 V	17.8 nC - Determines minimum gate drive strength required for <1 µs switching transitions in load-switch timing budgets.
R_θJA	153 °C/W - Defines thermal derating on standard FR-4 PCBs; limits usable power dissipation to ~0.83 W at ambient.

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
DMG2305UVT-7	R_DS(ON) = 48 mΩ @ −4.5 V; higher Q_g (22 nC); same SOT23-3 package	Marginally slower switching due to higher gate charge; identical thermal footprint	Preferred where slightly lower cost outweighs 25% higher gate drive energy requirement.
AO3401	R_DS(ON) = 52 mΩ @ −4.5 V; non-AEC-Q101; R_θJA = 170 °C/W	Lacks automotive qualification and has reduced thermal efficiency on FR-4	Suitable for consumer-grade portable electronics where AEC-Q101 and thermal margin are not required.

Compared with DMG2305UVT-7 and AO3401, DMP2070UQ offers the lowest R_DS(ON) and best thermal resistance among SOT23 P-channel MOSFETs with AEC-Q101 certification, making it optimal for automotive and high-reliability industrial load switching where conduction loss and junction temperature control are critical.

FAQ

What is the maximum safe operating junction temperature for DMP2070UQ?

The DMP2070UQ is rated for junction temperatures from −55 °C to +150 °C. Its absolute maximum T_J is +150 °C, and thermal derating begins above +25 °C ambient on standard FR-4 PCBs due to R_θJA = 153 °C/W. Operation beyond this limit risks permanent parametric shift or bond-wire failure.

Can DMP2070UQ be used in reverse-polarity protection circuits?

Yes - its integrated body diode conducts from source to drain when V_S < V_D, enabling reverse-polarity protection when placed in series with the positive supply rail. With V_SD = −0.7 to −1.1 V at −2.1 A, it provides low-loss protection without external diodes, provided gate is held at ground during fault conditions.

Does DMP2070UQ require external gate resistors for ESD or switching control?

No external gate resistor is required for ESD protection due to built-in gate protection diodes. For switching control, a small series resistor (≤10 Ω) may be added to damp ringing and reduce EMI, but the device's low C_iss (118 pF) and Q_g (17.8 nC) allow direct MCU GPIO drive without significant overshoot or shoot-through risk.

How does the R_DS(ON) change with temperature and gate voltage?

R_DS(ON) increases with junction temperature - normalized to ~1.15× at +125 °C vs. +25 °C for V_GS = −1.8 V. It also rises sharply below −2.5 V gate drive: 74 mΩ at −1.8 V vs. 44 mΩ at −4.5 V. Designers must verify worst-case R_DS(ON) using Figure 6 and Figure 4 from the datasheet under actual operating V_GS and T_J.
