Diodes Incorporated DMP6250SEQ-13

Overview

DMP6250SEQ-13 from Diodes Incorporated is a 60V P-channel enhancement-mode MOSFET in SOT223 package, rated for -6.1A continuous drain current at V_GS = -10V, with R_DS(ON) = 250 mΩ (max), qualified to AEC-Q101 and designed for automotive motor control, DC-DC converters, and power management functions.

For engineers reviewing the DMP6250SEQ-13 datasheet, DMP6250SEQ-13 pinout, DMP6250SEQ-13 application, or DMP6250SEQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, low gate charge (Q_g = 9.7 nC @ V_GS = -10V), 100% production-tested UIS capability, thermal resistance (R_θJC = 8.7 °C/W), and SOT223 lead-frame construction with matte tin annealed terminals.

Technical Context

This P-channel MOSFET operates as a high-side switch in automotive power rails, supporting load switching and reverse-polarity protection. Its gate threshold voltage (V_GS(TH) = -1 to -3 V) enables direct interface with 3.3 V/5 V logic controllers, while low input capacitance (C_iss = 551 pF) and fast switching (t_r = 10.3 ns, t_f = 39.8 ns) reduce drive losses in PWM-based systems.

The device features robust avalanche ruggedness (E_AS = 8 mJ, I_AS = -12 A) and thermally optimized SOT223 packaging with 14 W power dissipation at T_C = +25°C. Its body diode exhibits V_SD = -0.8 to -1.2 V at I_S = -2.0 A, enabling efficient freewheeling in synchronous buck or H-bridge topologies.

FAQ

What is the maximum safe operating junction temperature for DMP6250SEQ-13?

The absolute maximum junction temperature is +150°C, and the device is characterized for operation across -55°C to +150°C. Thermal design must ensure T_J remains below this limit under worst-case ambient and power dissipation conditions, using R_θJA = 69°C/W (FR-4 board) or R_θJC = 8.7°C/W (heatsink interface) as appropriate.

Is DMP6250SEQ-13 suitable for use in a high-side load switch with 3.3 V GPIO control?

Yes - its gate threshold voltage range of -1 V to -3 V allows reliable turn-on with 3.3 V logic when used in open-drain or push-pull configurations with appropriate level-shifting or gate pull-up. At V_GS = -3.3 V, R_DS(ON) is typically ~450 mΩ, sufficient for ≤2 A loads with acceptable conduction loss.

Does DMP6250SEQ-13 require external gate resistors in automotive motor drive applications?

Yes - a series gate resistor (typically 10–47 Ω) is recommended to dampen ringing caused by parasitic inductance and prevent unintended turn-on due to dV/dt coupling. This is especially critical in high-noise engine bay environments where fast switching edges interact with harness inductance.

How does the 100% UIS test impact reliability in motor control designs?

The 100% production UIS test verifies each unit's ability to absorb inductive energy (up to 8 mJ) without failure - directly preventing catastrophic failure during motor phase commutation or sudden load disconnection. This eliminates latent weaknesses not caught by standard parametric screening and significantly improves field MTBF in brushed DC motor systems.
