Product details

Overview

DMP68D1L-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -60V V_DSS, 7.5Ω R_DS(ON) @ V_GS = -10V, and -206mA continuous drain current at +25°C - designed for low-power load switching in space-constrained DC-DC converters and backlight circuits.

For engineers reviewing the DMP68D1L-7 datasheet, DMP68D1L-7 pinout, DMP68D1L-7 application, or DMP68D1L-7 equivalent, key selection criteria include gate threshold voltage (-0.8 to -2.1V), low input capacitance (42pF C_iss), fast switching (t_D(ON) = 11ns), thermal resistance (263°C/W), and automotive-qualified variant availability (DMP68D1LQ).

Technical Context

This MOSFET operates as a single-polarity, low-voltage logic-level switch with native gate drive compatibility down to -5V. Its -2.1V maximum V_GS(TH) ensures reliable turn-on with standard microcontroller GPIOs, while its 6pF Crss minimizes Miller-induced shoot-through risk in high-frequency PWM stages.

The device integrates ESD protection (HBM >2kV) and is qualified per JEDEC standards for high-reliability operation across -55°C to +150°C junction temperature range. Its 0.5W power dissipation rating on FR-4 PCB reflects thermal design constraints for unheatsinked surface-mount deployment.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-60V - supports rail-to-rail switching in 48V industrial control subsystems without derating.
R_DS(ON)	7.5Ω @ V_GS = -10V - enables <150mW conduction loss at -100mA, critical for battery-powered sensor nodes.
I_D (max)	-206mA @ T_A = +25°C - defines safe steady-state load capacity for LED driver or motor gate bias circuits.
C_iss	42pF - reduces gate drive energy requirement and speeds up turn-on in 1MHz+ DC-DC controllers.
t_D(ON)	11ns - limits overlap time in synchronous buck topologies, directly lowering cross-conduction losses.
R_θJA	263°C/W - mandates minimum 1-inch² copper pour for sustained 0.5W operation at ambient ≤50°C.
V_GS(TH)	-0.8 to -2.1V - guarantees activation with 3.3V/5V logic outputs without level-shifting circuitry.

Pinout & Package

Package: SOT23 - surface-mount plastic package with 3 terminals, 0.008g mass, UL 94V-0 rated molding compound, and matte tin–annealed Alloy 42 leadframe.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Current return path for P-channel conduction	Connected to higher potential rail; requires stable reference for gate control.
2 (Gate)	Control electrode for channel formation	High-impedance input; sensitive to ESD; requires <100Ω series resistor for ringing suppression.
3 (Drain)	Load-side current terminal	Switches negative-side loads; body diode conducts from source to drain when reverse-biased.

Key Features

Feature	Design Value
Low R_DS(ON) at low V_GS	8.0Ω @ V_GS = -5V - enables direct interface with 5V microcontrollers without gate drivers.
ESD protection	HBM >2kV - eliminates need for external TVS diodes in handheld medical or portable instrumentation.
Thermal robustness	150°C max T_J - sustains operation in sealed enclosures with limited airflow (e.g., smart lighting modules).
Green compliance	Halogen-free, antimony-free, RoHS 3 compliant - meets IPC-1752A reporting requirements for automotive Tier-1 BOMs.
Fast switching	t_F = 30ns - reduces transition losses in 500kHz–1MHz LED dimming circuits.

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
DMN601WK-7	Lower R_DS(ON) (4.5Ω @ -10V) but higher C_iss (65pF); SOT23-3 same footprint	Better conduction efficiency but slower switching; suited for <500kHz DC-DC where loss dominates timing	Select when minimizing I²R loss is priority over EMI-sensitive high-frequency operation.
AO3401	Higher ID rating (-4A) but larger SO-8 package; R_DS(ON) = 55mΩ @ -4.5V	Requires PCB redesign; suitable only when board space permits and higher current capability is needed	Choose only if system demands >500mA load current and thermal budget allows SO-8 mounting.

Compared with DMN601WK-7 and AO3401, DMP68D1L-7 delivers optimal balance of ultra-low gate charge (0.6nC), compact SOT23 size, and -60V ruggedness - making it uniquely suited for space-constrained, medium-voltage, low-current switching where layout density and transient immunity are co-critical.

FAQ

What is the maximum safe operating junction temperature for DMP68D1L-7?

The absolute maximum junction temperature is +150°C, validated per JEDEC JESD22-A108. Operation above this limit risks permanent parametric shift in V_GS(TH) and R_DS(ON). Derating is required above +125°C ambient when dissipating >0.3W on standard FR-4 PCB.

Can DMP68D1L-7 be used in automotive applications?

Yes - the automotive-qualified variant DMP68D1LQ is AEC-Q101 qualified and shares identical electrical specs. DMP68D1L-7 itself is not AEC-Q101 certified but meets JEDEC high-reliability standards and is widely deployed in non-safety-critical automotive body electronics (e.g., mirror heaters, seat controls).

Does DMP68D1L-7 require a gate resistor for stability?

A 10–100Ω series gate resistor is recommended to dampen parasitic oscillation caused by PCB trace inductance interacting with 42pF C_iss. Without it, ringing exceeding ±30V can occur during fast transitions, risking gate oxide damage or false triggering in adjacent logic.

How does R_DS(ON) change with temperature?

R_DS(ON) increases linearly with junction temperature: normalized to 1.0× at +25°C, it reaches ~1.7× at +150°C (Figure 6). At -55°C, it drops to ~0.85× - critical for cold-start performance in outdoor industrial sensors.
