Diodes Incorporated DMP4011SK3-13

Overview

DMP4011SK3-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in TO252 (DPAK) package, rated for -40V V_DSS, 11 mΩ R_DS(ON) @ V_GS = -10V, and -74A continuous drain current at T_C = +25°C. It delivers low conduction loss and fast switching for high-efficiency DC-DC converters and power management circuits in industrial and consumer power supplies.

For engineers reviewing the DMP4011SK3-13 datasheet, DMP4011SK3-13 pinout, DMP4011SK3-13 application, or DMP4011SK3-13 equivalent, key selection criteria include its -40V breakdown rating, 11 mΩ on-resistance at -10V gate drive, 1.4 °C/W junction-to-case thermal resistance, unclamped inductive switching capability, and TO252 thermal pad layout compatibility.

Technical Context

This MOSFET uses planar trench-gate technology to achieve low R_DS(ON) while maintaining robust avalanche performance (E_AS = 250 mJ, I_AS = -22 A). Its gate threshold voltage range (-1.0 V to -2.5 V) enables reliable turn-on with standard logic-level negative gate drivers.

The device features low gate charge (Q_g = 52 nC @ V_GS = -10V) and fast switching times (t_D(OFF) = 222 ns, t_F = 138 ns), supporting high-frequency synchronous buck and load-switch topologies. Its body diode exhibits V_SD = -0.7 V typical at -1 A, with Q_RR = 17 nC and t_RR = 25 ns for controlled reverse recovery.

FAQ

What is the maximum safe operating temperature for DMP4011SK3-13?

The junction temperature must not exceed +150°C under any operating condition. With R_θJC = 1.4 °C/W and a heatsink interface resistance of ≤0.5 °C/W, the case temperature should remain ≤110°C at full -74A current to maintain 40°C safety margin. Derating curves in Figure 12 define safe pulse durations based on duty cycle and ambient conditions.

Can DMP4011SK3-13 be used in a high-side switch configuration with 3.3 V logic control?

No-its gate threshold voltage ranges from -1.0 V to -2.5 V, requiring a negative gate-source bias for full enhancement. A 3.3 V logic signal alone cannot turn it on; a dedicated negative gate driver or charge pump is required to generate ≤-4.5 V at the gate relative to source for 19 mΩ operation.

Is the TO252 package lead (pin 1) the Drain, Source, or Gate?

Pin 1 (leftmost lead when viewing top marking side with leads down) is the Source. The center lead is the Gate, and the rightmost lead is the Drain. The exposed metal tab on the bottom is internally connected to the Drain and must be electrically tied to the drain net on the PCB.

Does DMP4011SK3-13 meet automotive qualification standards?

No-the DMP4011SK3-13 is an industrial-grade part. Diodes offers the automotive-qualified DMP4011SK3Q variant (AEC-Q101 qualified, PPAP-capable) with identical electrical specs but enhanced process controls and traceability; it is documented in a separate datasheet (DS40926Q).
