Diodes Incorporated DMP3021SFVWQ-13

Overview

DMP3021SFVWQ-13 from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in PowerDI3333-8 package, qualified to AEC-Q101 and PPAP-capable for automotive use. It delivers 15 mΩ R_DS(ON) at V_GS = −10 V, supports −42 A continuous drain current at T_C = +25°C, and features integrated ESD protection on the gate. It is deployed in backlighting drivers and DC-DC converter high-side switches.

For engineers reviewing the DMP3021SFVWQ-13 datasheet, DMP3021SFVWQ-13 pinout, DMP3021SFVWQ-13 application, or DMP3021SFVWQ-13 equivalent, key selection criteria include its AEC-Q101 qualification status, low R_DS(ON) at −5 V gate drive, thermal resistance of 3.6 °C/W (junction-to-case), and compatibility with compact automotive power-management layouts.

Technical Context

This P-channel MOSFET operates as a high-side switch in automotive power rails, leveraging its negative threshold voltage (−1.0 to −2.5 V) and robust avalanche rating (13 A, 84 mJ). Its gate charge profile (34 nC at V_GS = −10 V) enables fast switching in synchronous buck converters while maintaining low conduction loss.

The PowerDI3333-8/SWP package integrates an exposed drain pad for direct thermal coupling to PCB copper, achieving R_θJC = 3.6 °C/W. Its dynamic parameters-including C_iss = 1799 pF, C_oss = 259 pF, and t_R = 18.3 ns-support stable operation in 200–500 kHz DC-DC topologies with minimal switching loss.

FAQ

What is the maximum safe operating temperature for DMP3021SFVWQ-13?

The device has a specified junction temperature range of −55°C to +150°C. Under continuous DC operation at T_C = +70°C, the maximum allowable power dissipation is 34 W (calculated from R_θJC = 3.6 °C/W and ΔT = 80°C). Derating is required above +70°C case temperature per Figure 5 and Figure 7 in DS43269 Rev. 6-2.

Does DMP3021SFVWQ-13 require an external gate resistor for automotive PWM switching?

Yes - a 3 Ω gate resistor is used in the datasheet's switching time test (t_D(ON), t_R). For 300 kHz operation with 1.7 A peak gate drive, a 2.2–4.7 Ω series resistor ensures controlled dV/dt, minimizes ringing, and prevents shoot-through in half-bridge configurations without compromising rise/fall times.

Can DMP3021SFVWQ-13 be used in a synchronous buck converter as the high-side switch?

Yes - its −30 V V_DSS, −42 A I_D, and 34 nC Q_g support high-side operation in 12 V input buck converters up to 500 kHz. Gate drive must swing between 0 V and −10 V (or −12 V) with sufficient current capability (>1.5 A peak) to achieve the specified 18.3 ns rise time.

Is the PowerDI3333-8/SWP package lead-free and RoHS compliant?

Yes - the DMP3021SFVWQ-13 uses matte tin-annealed terminals over copper leadframe and conforms to EU RoHS 2011/65/EU and RoHS 3 2015/863/EU. It is also halogen- and antimony-free ("Green"), with Br + Cl < 1500 ppm and Sb < 1000 ppm per Diodes' definition.
