Product details

Overview

ZXM64P03X from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in MSOP-8 package, featuring 75 mΩ R_DS(on) at V_GS = −10 V, −3.8 A continuous drain current at 25°C, and fast switching (t_d(off) = 40 ns, Q_g = 46 nC), deployed as a high-efficiency synchronous rectifier and load switch in DC–DC converters.

For engineers reviewing the ZXM64P03X datasheet, ZXM64P03X pinout, ZXM64P03X application, or ZXM64P03X equivalent, key selection criteria include its low gate threshold (V_GS(th) = −1.0 V), body diode forward voltage (V_SD = −0.95 V), thermal resistance (R_θJA = 70 °C/W under PCB conditions), and AEC-Q101 qualification for automotive power management.

Technical Context

This P-channel MOSFET operates with negative gate drive relative to source, enabling high-side switching without level-shifting circuitry. Its low R_DS(on) at −4.5 V (100 mΩ) supports 3.3 V logic-compatible control in compact power rails.

The device integrates a fast-recovery body diode (t_rr = 30.2 ns, Q_rr = 27.8 nC) and exhibits low input capacitance (C_iss = 825 pF) and gate charge (Q_g = 46 nC), reducing switching losses in high-frequency (>500 kHz) buck and load-switch topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Rating	−30 V - supports 24 V nominal bus systems with 20 % margin against transients
R_DS(on) @ −10 V	75 mΩ - enables ≤0.69 W conduction loss at −2.4 A continuous current
I_D Continuous	−3.8 A @ 25°C - suitable for 5–10 W point-of-load regulation with derating above 70°C
V_GS(th)	−1.0 V max - ensures reliable turn-on with 3.3 V microcontroller GPIOs
Q_g	46 nC - determines gate driver current requirement (~4.6 mA avg at 100 kHz)
t_d(off)	40 ns - limits minimum off-time to ~100 ns in synchronous buck controllers
R_θJA	70 °C/W - requires ≥1 cm² copper pour for 1.1 W dissipation at <100°C junction rise

Pinout & Package

Package: MSOP-8 (3.0 mm × 4.9 mm × 1.1 mm height), surface-mount, lead-free, halogen-free, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4	Drain (D)	Parallel-connected internal drain terminals - low-inductance path for high-current output
5	Gate (G)	Control input requiring negative voltage relative to source; 46 nC total charge
6, 7, 8	Source (S)	Common return node; also forms cathode of integrated body diode

Key Features

Feature	Design Value
Low gate threshold voltage	V_GS(th) ≤ −1.0 V - enables direct drive from 3.3 V logic without level shifter
Fast body diode recovery	t_rr = 30.2 ns, Q_rr = 27.8 nC - reduces cross-conduction loss in synchronous rectification
Thermally enhanced MSOP-8	R_θJA = 70 °C/W - improves power density vs. standard SO-8 by 30 % with same footprint
AEC-Q101 qualified	Qualified for automotive power management - supports temperature cycling (−55°C to +150°C) and HTRB stress

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3026LSD-13	R_DS(on) = 50 mΩ @ −10 V; higher ID (−4.5 A); SO-8 package	Larger footprint; higher thermal mass; not MSOP-8 compatible	Select when board space allows SO-8 and lower on-resistance is prioritized over size
SI3457DV-T1-GE3	R_DS(on) = 110 mΩ @ −4.5 V; smaller TSOP-6 package; no AEC-Q101 rating	Lower current capability (−2.5 A); unqualified for automotive use	Select for cost-sensitive consumer DC–DC where AEC-Q101 is not required

Compared with DMN3026LSD-13 and SI3457DV-T1-GE3, ZXM64P03X uniquely balances MSOP-8 miniaturization, −30 V rating, AEC-Q101 compliance, and 100 mΩ R_DS(on) at −4.5 V - making it optimal for space-constrained automotive and industrial load switches where 3.3 V logic compatibility and reliability are mandatory.

FAQ

What is the maximum safe gate-source voltage for ZXM64P03X?

The absolute maximum V_GS is ±20 V per the datasheet's Maximum Ratings table. Exceeding this risks oxide breakdown. For reliable operation, gate drive should be limited to −12 V maximum when using −10 V logic-level turn-on, with transient clamping recommended if driving from higher-voltage sources.

Can ZXM64P03X be used in linear regulator applications?

No - ZXM64P03X is optimized for switching operation, not linear regulation. Its R_DS(on) is specified only at V_GS = −10 V and −4.5 V, and thermal resistance (R_θJA = 70 °C/W) assumes pulsed or switched duty cycles. Linear use would exceed safe operating area due to simultaneous high V_DS and I_D.

Is the body diode suitable for reverse polarity protection?

Yes - the integrated body diode is oriented anode-to-source, cathode-to-drain, allowing forward conduction from source to drain. When placed high-side with source tied to input, it blocks reverse current flow, providing effective reverse polarity protection up to −30 V with V_SD = −0.95 V at −2.4 A.

Does ZXM64P03X require a gate resistor for EMI suppression?

A gate resistor (typically 10–47 Ω) is recommended to dampen ringing caused by gate-drain capacitance (C_rss = 80 pF) and PCB trace inductance. Without it, fast edges (t_r = 6.2 ns) may excite parasitic resonances, increasing radiated emissions - especially critical in automotive EMC-compliant designs.
