Product details

Overview

DMP2067LVT-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET designed for low-voltage power switching in compact, high-efficiency systems. It delivers 45 mΩ R_DS(ON) at V_GS = −4.5 V, supports −4.2 A continuous drain current at +25°C, and features a −20 V drain-source breakdown voltage. Its TSOT26 package enables space-constrained load switching in portable battery-powered devices.

For engineers reviewing the DMP2067LVT-7 datasheet, DMP2067LVT-7 pinout, DMP2067LVT-7 application, or DMP2067LVT-7 equivalent, key selection criteria include gate threshold voltage (−0.4 to −1.5 V), low input capacitance (1575 pF), thermal resistance (105 °C/W on FR-4), body diode forward voltage (−0.7 to −1.4 V), and pulsed drain capability (−30 A).

Technical Context

This MOSFET operates as a single P-channel switch with depletion-free enhancement-mode behavior, requiring negative gate drive relative to source. Its low V_GS(TH) enables direct interface with 3.3 V logic controllers without level shifting, while its 89 pF Crss and 15 nC total gate charge support fast, low-loss switching up to several hundred kHz.

The device integrates a monolithic body diode with 13 ns reverse recovery time and 6.7 nC Q_RR, enabling synchronous rectification and flyback energy recovery in DC-DC converters. Thermal performance is characterized under two PCB conditions: 105 °C/W (standard FR-4) and 78 °C/W (enhanced 1-inch copper pad), defining safe operating area boundaries for transient and steady-state loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	−20 V: Maximum blocking voltage before avalanche conduction; defines use in ≤12 V rail systems with margin.
R_DS(ON) @ V_GS = −4.5 V	45 mΩ max: Enables <190 mW conduction loss at −4.2 A, critical for thermally constrained PCBs.
I_D Continuous	−4.2 A @ +25°C: Sustained load current rating on standard FR-4 layout; derates to −3.4 A at +70°C.
V_GS(TH)	−0.4 to −1.5 V: Ensures full enhancement with 3.3 V logic outputs; avoids partial turn-on in noise-prone environments.
C_iss	1575 pF: Determines gate drive strength requirement; compatible with low-power microcontroller GPIOs via series resistor.
t_RR	13 ns: Supports high-frequency synchronous rectification with minimal switching loss and voltage overshoot.
P_D (FR-4)	1.2 W: Power dissipation limit on standard 2 oz copper board; sets maximum continuous power handling.

Optimized body diode	V_SD = −0.7 V typ at −2.1 A supports efficient freewheeling in buck regulators and H-bridge topologies.

Applications

Battery Protection Circuit

USB Port Power Switch

Use Scenario: Reverse-current blocking and overcurrent shutdown in Li-ion battery packs using integrated protection ICs.

IC Role / Device Role: High-side load switch controlling discharge path between cell stack and system load.

Use Value: 45 mΩ R_DS(ON) minimizes voltage drop during full-load discharge, preserving battery runtime and state-of-charge accuracy.

Use Scenario: Hot-swap enable/disable of USB VBUS to peripheral devices in portable hubs and docking stations.

IC Role / Device Role: Controlled P-channel switch isolating downstream ports during insertion/removal or fault events.

Use Value: −1.5 V max V_GS(TH) ensures clean turn-off when host controller pulls gate high, preventing backfeed into upstream port.

DC-DC Converter Synchronous Rectifier

Industrial Sensor Node Power Gating

Use Scenario: Secondary-side rectification in non-isolated buck converters powering FPGA I/O banks or memory subsystems.

IC Role / Device Role: Low-loss synchronous rectifier replacing Schottky diode to improve light-load efficiency.

Use Value: 13 ns t_RR and 6.7 nC Q_RR reduce switching losses and ringing, enabling stable operation at 500 kHz–1 MHz.

Use Scenario: Periodic power cycling of environmental sensors (e.g., temperature/humidity) in wireless IoT nodes to extend battery life.

IC Role / Device Role: Ultra-low-quiescent-load power gate enabling <1 μA off-state leakage (IDSS ≤ −1 μA).

Use Value: Sub-μA IDSS preserves multi-year battery life in duty-cycled sensor applications where standby current dominates energy budget.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel MOSFET switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2053LVT-7	R_DS(ON) = 50 mΩ @ −4.5 V; higher V_GS(TH) (−0.5 to −2.0 V); same TSOT26 package.	Slightly lower efficiency at full load; less robust turn-on margin with 3.3 V logic.	Select if cost sensitivity outweighs 5 mΩ R_DS(ON) penalty and tighter V_GS(TH) tolerance is acceptable.
AO3401	R_DS(ON) = 44 mΩ @ −4.5 V; higher C_iss (1900 pF); SO-23 package (larger footprint, higher thermal resistance).	Requires larger PCB area and dissipates more heat on equivalent layout; slower switching due to higher capacitance.	Choose only if legacy SO-23 footprint compatibility is mandatory and thermal headroom exceeds 1.2 W.

Compared with DMN2053LVT-7 and AO3401, DMP2067LVT-7 offers the lowest combination of R_DS(ON), gate charge, and thermal resistance in TSOT26, making it optimal for space- and efficiency-critical 3.3 V–5 V load switching where rapid, low-loss control is required.

FAQ

What is the maximum safe gate-source voltage for DMP2067LVT-7?

The absolute maximum V_GS rating is ±8 V. Exceeding this risks permanent gate oxide damage. In practice, gate drive should be limited to −4.5 V or −8 V for full enhancement, with no positive voltage applied-since it is a P-channel device, the gate must remain at or below the source potential to avoid unintended conduction or stress.

Can DMP2067LVT-7 be used in linear (analog) regulation mode?

No-it is not characterized or guaranteed for linear operation. The Safe Operating Area (SOA) curve shows only pulse and DC limits under switching conditions. Linear use would cause uncontrolled thermal runaway due to positive temperature coefficient of R_DS(ON) and lack of SOA derating data for analog bias points.

Is the body diode suitable for reverse polarity protection?

Yes-the integrated body diode conducts from source to drain (S→D) when V_DS > 0, enabling reverse-polarity protection in high-side configurations. With V_SD = −0.7 V typical at −2.1 A, it provides low-loss blocking with minimal voltage drop, but requires external fuse or current limiting for sustained reverse faults.

Does DMP2067LVT-7 require a gate resistor in typical switching applications?

A small gate resistor (10–100 Ω) is recommended to dampen ringing caused by L_g–C_iss resonance and control dV/dt during switching transitions. While not strictly required for basic on/off control, omitting it may cause EMI, shoot-through in half-bridges, or false triggering in noise-sensitive systems.
