Product details

Overview

DMP3021SPSW from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in PowerDI5060-8 (Type UX) package, optimized for high-efficiency power management with 9.8 mΩ R_DS(on) at V_GS = −10 V, −52.7 A continuous drain current at T_C = +25°C, and 2 Ω thermal resistance from junction to case-used in DC-DC converters and analog switching circuits.

For engineers reviewing the DMP3021SPSW datasheet, DMP3021SPSW pinout, DMP3021SPSW application, or DMP3021SPSW equivalent, key selection criteria include low on-resistance at −5 V gate drive, fast switching (t_F = 23.7 ns), body diode recovery (t_RR = 14.9 ns), and thermal performance in thin-profile power stages.

Technical Context

This MOSFET employs trench-gate silicon process technology to achieve low R_DS(on) while maintaining controlled gate charge (Q_g = 34 nC at V_GS = −10 V) and low output capacitance (C_oss = 259 pF). Its −1.0 V to −2.5 V gate threshold enables robust turn-on control under varying bias conditions.

The device integrates ESD protection and a built-in gate protection diode. Its PowerDI5060-8 package features an exposed drain pad for direct thermal coupling to PCB copper, delivering R_θJC = 2 °C/W and supporting high-current pulsed operation up to −197 A (10 µs, 1% duty).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	−30 V: Maximum blocking voltage for 12 V and 24 V rail applications with margin.
R_DS(on) max	15 mΩ @ V_GS = −10 V: Enables <1.5 W conduction loss at 40 A in synchronous buck high-side switches.
I_D continuous	−52.7 A @ T_C = +25°C: Supports high-current load switching when mounted on thermally enhanced PCBs.
Q_g	34 nC @ V_GS = −10 V: Determines gate driver power requirement and switching loss in hard-switched topologies.
t_RR	14.9 ns: Limits reverse recovery energy loss and cross-conduction risk in synchronous rectification.
R_θJC	2 °C/W: Allows direct thermal path to heatsink or internal copper plane for sustained high-power operation.

Pinout & Package

Package: PowerDI5060-8 (Type UX), surface-mount, 8-terminal, exposed drain pad (D), 1.1 mm profile, RoHS-compliant matte tin finish over copper leadframe.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8 (Bottom View)	Drain (D), Source (S), Gate (G)	Pins 1–4 and 6–8 are parallel-connected drain terminals; Pin 5 is gate; Pins 2–4 and 6–8 share source connection-enables low-inductance, high-current routing with distributed thermal paths.

Key Features

Feature	Design Value
Low R_DS(on) at −5 V drive	25 mΩ: Enables efficient operation with logic-level gate drivers in battery-powered systems.
Fast switching speed	t_F = 23.7 ns: Reduces transition losses in high-frequency (>500 kHz) DC-DC converters.
Low input capacitance	C_iss = 1799 pF: Minimizes gate drive current demand and improves EMI behavior.
Thin package profile	1.1 mm max height: Fits space-constrained modules such as USB-C PD adapters and portable power banks.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMT3006LPSQ-13	R_DS(on) = 6.5 mΩ @ −10 V; smaller PowerDI3333 package; lower I_D (−30 A).	Better for compact, lower-current designs where thermal mass is limited.	Select when board area is constrained and peak current ≤30 A.
Si7157DP-T1-GE3	R_DS(on) = 12.5 mΩ @ −10 V; SO-8 package; higher R_θJA (62 °C/W).	Preferred for legacy SO-8 footprints and manual rework compatibility.	Choose when leveraging existing SO-8 layout and thermal design.

Compared with DMP3021SPSW, DMT3006LPSQ-13 offers lower on-resistance in a smaller footprint but sacrifices current handling; Si7157DP-T1-GE3 trades thermal efficiency for mechanical compatibility-making DMP3021SPSW optimal for high-current, thermally demanding PowerDI5060-8 implementations.

FAQ

What is the maximum safe operating temperature for DMP3021SPSW?

The junction temperature must not exceed +150°C, and the storage temperature range is −55°C to +150°C. With R_θJC = 2 °C/W, sustained 50 A operation requires case temperature ≤100°C-achievable using ≥1-inch² 2 oz copper thermal pad per JEDEC Std 51-14.

Does DMP3021SPSW require a gate resistor for stability?

Yes-a series gate resistor (typically 3–10 Ω) is recommended to dampen ringing caused by gate-drain capacitance (C_rss = 225 pF) and PCB inductance. The datasheet specifies t_D(on) and t_R test conditions using R_G = 3 Ω, confirming its role in controlling dv/dt and EMI.

Can DMP3021SPSW be used in automotive applications?

No-this part is not AEC-Q101 qualified. Diodes offers automotive-grade variants (e.g., DMP3021SPSWQ-13) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation; standard DMP3021SPSW is intended for commercial/industrial use only.

How does the PowerDI5060-8 package improve thermal performance over SO-8?

The exposed drain pad in PowerDI5060-8 provides direct thermal conduction to PCB copper, achieving R_θJC = 2 °C/W-over 10× better than typical SO-8 R_θJC (~25–30 °C/W). This allows 2.5× higher continuous current at same case temperature, verified per JEDEC 51-14 mounting standards.
