Product details

Overview

PMPB48EPAX from Nexperia is a 30 V, P-channel enhancement-mode Trench MOSFET in a DFN2020MD-6 (SOT1220) leadless ultra-thin SMD package, designed for high-side load switching and relay driving in automotive and industrial power control circuits. It delivers R_DS(on) = 40 mΩ at V_GS = −10 V and I_D = −4.7 A, supports AEC-Q101 qualification, and features side-wettable flanks for optical solder inspection.

For engineers reviewing the PMPB48EPAX datasheet, PMPB48EPAX pinout, PMPB48EPAX application, or PMPB48EPAX equivalent, this device is selected for compact high-reliability DC power switching where low on-resistance, thermal robustness, and automotive-grade stress qualification are required - especially in space-constrained PCB layouts with FR4 mounting pad constraints.

Technical Context

This P-channel MOSFET operates in enhancement mode with a gate-source threshold voltage (V_GS(th)) of −1.5 V (typ), enabling turn-on with logic-level gate drive down to −4.5 V. Its trench architecture ensures stable R_DS(on) over temperature, with 60 mΩ max at T_j = 150 °C and V_GS = −10 V.

The device integrates an intrinsic source-drain diode with V_SD = −0.8 V (typ) at I_S = −1.8 A and exhibits fast switching dynamics: t_d(on) = 7.4 ns, t_f = 10.4 ns, and Q_G(tot) = 17 nC (typ), supporting efficient PWM control in high-speed line driver and load-switching topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	−30 V maximum drain-source voltage - defines safe blocking capability in 24 V automotive and industrial bus applications.
R_DS(on)	40 mΩ typ at V_GS = −10 V, I_D = −4.7 A, T_j = 25 °C - enables <190 mW conduction loss at full rated current.
I_D	−4.7 A continuous drain current at T_amb = 25 °C - supported by 6 cm² drain pad on FR4 PCB per datasheet layout guidance.
Q_G(tot)	17 nC typical total gate charge - determines gate driver strength requirement for <50 ns switching transitions under 6 Ω external gate resistance.
T_j max	150 °C maximum junction temperature - validated for sustained operation in under-hood and industrial ambient environments.
AEC-Q101	Qualified per Automotive Electronics Council standard - confirms reliability for automotive power management without derating.

Pinout & Package

DFN2020MD-6 (SOT1220) is a 2.0 × 2.0 × 0.65 mm leadless thermally enhanced plastic package with side-wettable flanks for automated optical inspection. The exposed drain terminals provide low thermal resistance (R_th(j-sp) = 67 K/W typ) and mechanical stability.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6, 7	Drain (D)	Five parallel drain terminals - collectively form low-inductance, high-current path to PCB copper pour; critical for thermal dissipation and SOA compliance.
3	Gate (G)	Single gate input - requires clean, low-impedance drive to minimize switching losses; gate resistance R_G = 6 Ω (typ) affects Miller plateau timing.
4, 8	Source (S)	Two source terminals - provide return path for load current and reference for gate drive; must be routed with low inductance in high-di/dt applications.

Key Features

Feature	Design Value
Side-wettable flanks	Enables automated optical inspection (AOI) of solder joints without X-ray - reduces post-reflow defect escape in high-volume automotive assembly.
Trench MOSFET process	Delivers 25% lower R_DS(on) vs planar P-channel equivalents at same die size - improves power density in space-constrained modules.
Ultra-thin 0.65 mm profile	Reduces board stack height in multi-layer modules - compatible with conformal coating and tight mechanical envelopes in ADAS and body control units.
FR4-optimized thermal design	Specified R_th(j-a) = 235 K/W on single-sided 6 cm² drain pad - allows accurate thermal modeling without specialized metal-core PCBs.

Applications

Relay Driver

High-Side Load Switch

Use Scenario: Replacing electromechanical relays in 12–24 V vehicle body control modules for door locks, lighting, and HVAC actuators.

IC Role / Device Role / Timing Role: High-side P-channel switch controlling load current flow from battery rail to grounded load; driven by microcontroller GPIO via level-shifting or direct logic-compatible gate drive.

Use Value: Eliminates relay coil power consumption (~100–300 mW), reduces acoustic noise and mechanical wear, and enables diagnostic current sensing via R_DS(on).

Use Scenario: Power sequencing and fault-isolation in industrial PLC I/O modules requiring controlled 24 V DC output enable/disable.

IC Role / Device Role / Timing Role: High-side switch placed between supply rail and downstream circuitry; configured for soft-start via gate RC network or PWM-controlled ramp-up.

Use Value: Prevents inrush current damage during hot-plug events and supports brown-out recovery with precise turn-off timing (t_f = 10.4 ns).

High-Speed Line Driver

Switching Circuit

Use Scenario: Bidirectional signal conditioning in CAN FD or LIN transceiver interface protection stages requiring fast transient response.

IC Role / Device Role / Timing Role: Active clamping element in overvoltage protection path; switched synchronously with data edges to limit bus voltage excursions.

Use Value: Leverages fast t_d(off) = 27 ns and low Q_GD = 3.2 nC to suppress ESD-induced glitches without distorting signal integrity up to 5 Mbps.

Use Scenario: DC-DC converter synchronous rectification or buck converter high-side switch in non-isolated point-of-load regulators.

IC Role / Device Role / Timing Role: Main power switch in hard-switched topology; operated with fixed-frequency PWM and dead-time control to avoid shoot-through.

Use Value: Achieves >92% efficiency at 3 A output due to low R_DS(on) and minimal Q_G-driven gate loss - validated across 25–125 °C ambient range.

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
DMG2305UVT-7	R_DS(on) = 48 mΩ @ V_GS = −4.5 V; smaller 1.6 × 1.6 mm package; no AEC-Q101 qualification.	Better suited for consumer portables than automotive; lacks side-wettable flanks and thermal spec validation on FR4.	Select when cost and footprint are prioritized over automotive qualification and AOI support.
SI2301DDS-T1-BE3	R_DS(on) = 115 mΩ @ V_GS = −4.5 V; SOT-23 package; higher R_DS(on), lower I_D rating (−2.6 A).	Limited to low-power loads (<1 W); unsuitable for relay replacement or high-current switching circuits.	Choose only for ultra-low-cost, low-current bias or signal-switching roles - not for power switching.

Compared with DMG2305UVT-7 and SI2301DDS-T1-BE3, PMPB48EPAX provides superior thermal performance on standard FR4, guaranteed AEC-Q101 reliability, and optimized geometry for automated optical inspection - making it the preferred choice for production automotive and industrial power switches demanding zero-defect assembly.

FAQ

What is the maximum continuous drain current for PMPB48EPAX at 100 °C ambient temperature?

The maximum continuous drain current is −3 A at T_amb = 100 °C, as specified in Table 5 (Limiting values). This derating reflects thermal limits on a standard FR4 PCB with single-sided 6 cm² drain pad; actual current capability depends on board layout, airflow, and heatsinking.

Does PMPB48EPAX require a gate resistor for stable switching in high-speed applications?

Yes - a 6 Ω external gate resistor is used in the datasheet's switching time test conditions (V_DS = −15 V, I_D = −4.7 A). This value balances switching speed (t_f = 10.4 ns) against ringing and EMI; lower values increase dV/dt stress and risk oscillation without proper PCB layout.

Can PMPB48EPAX be used in reverse polarity protection circuits?

Yes - its P-channel configuration and −30 V V_DS rating make it suitable for reverse-voltage protection on 24 V supplies. When placed in the high-side position with gate tied to ground, it conducts only during correct polarity and blocks reverse current via its intrinsic body diode orientation.

Is the DFN2020MD-6 package compatible with standard reflow profiles for lead-free soldering?

Yes - Nexperia specifies compatibility with JEDEC J-STD-020D peak reflow temperatures up to 260 °C. Figure 19 provides the exact solder land pattern (0.33 mm × 0.76 mm pads, 0.65 mm pitch), and the side-wettable flanks enable post-reflow AOI verification without X-ray.
