Product details
Overview
ZXMP4A16GQTA from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET in SOT223 package, featuring 60mΩ RDS(on) at VGS = −10V, −6.4A continuous drain current, and fast switching with 2.33ns turn-on delay. It serves as a high-efficiency synchronous rectifier or load switch in DC-DC converters and LED backlighting circuits.
For engineers reviewing the ZXMP4A16GQTA datasheet, ZXMP4A16GQTA pinout, ZXMP4A16GQTA application, or ZXMP4A16GQTA equivalent, key selection criteria include its −40V VDSS, low gate charge (13.6nC at VGS = −5V), body diode forward voltage of −0.85V, and thermal resistance of 32°C/W on 25mm × 25mm FR4 PCB - all critical for compact, thermally constrained power management designs.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(on) while preserving fast switching dynamics. Its −1.0V gate threshold voltage enables reliable turn-on with standard logic-level drive, and its 1,007pF input capacitance supports stable gate control under typical PWM frequencies up to 1MHz.
The device integrates a robust intrinsic body diode with 27.2ns reverse recovery time and 25.4nC Qrr, making it suitable for freewheeling paths in buck converters. Thermal design is supported by two distinct power dissipation ratings: 3.9W (RθJA = 32°C/W) on copper-clad PCBs and 2.0W (RθJA = 62.5°C/W) on standard FR4 - enabling accurate junction temperature estimation across board layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −40V - Withstands up to 40V reverse drain-source voltage without breakdown, suitable for 24V system rails with margin. |
| RDS(on) | 60mΩ @ VGS = −10V - Delivers <0.23W conduction loss at −3.8A, minimizing heat generation in high-current paths. |
| ID | −6.4A @ TA = +25°C - Supports continuous load currents up to 6.4A with adequate PCB copper area for thermal management. |
| Qg | 13.6nC @ VGS = −5V - Enables efficient gate driving with low controller output current demand and reduced switching losses. |
| Ciss | 1,007pF @ VDS = −20V - Stabilizes gate drive loop response and limits EMI during hard-switching transitions. |
| VSD | −0.85V @ IS = −3.4A - Reduces forward conduction loss in body-diode conduction mode versus discrete Schottky alternatives. |
| tr | 8.84ns - Limits overlap time between high-side and low-side switching, reducing shoot-through risk in half-bridge topologies. |
Pinout & Package
Package: SOT223 (Type DN), surface-mount, 4-terminal plastic molded package with exposed drain pad for thermal enhancement. Moisture sensitivity level 1 per J-STD-020; matte tin-plated terminals; RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Connected to higher potential node in P-channel configuration; ties to ground or return path in high-side switch layout. |
| Pin 2 (Gate) | Control input | Accepts negative gate drive relative to source; −1.0V VGS(th) ensures compatibility with 3.3V/5V logic-level controllers via level-shifting or inverted drive. |
| Pin 3 (Drain) | Power output | Exposed metal tab - electrically and thermally connected to drain; must be soldered to large copper pour for thermal performance. |
| Pin 4 (Source) | Source terminal (dual-source connection) | Second source lead reduces source inductance and improves current sharing; used in parallel with Pin 1 for low-impedance return path. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) | 60mΩ at −10V enables <0.23W conduction loss at 3.8A, directly improving converter efficiency over competitive P-FETs. |
| Fast switching speed | 2.33ns tD(on) and 8.84ns tr support >500kHz PWM operation with minimal dead-time overhead in synchronous rectification. |
| Optimized body diode | 27.2ns trr and 25.4nC Qrr reduce reverse-recovery losses and EMI in discontinuous-conduction-mode (DCM) buck stages. |
| Thermal-enhanced SOT223 | 32°C/W RθJA on 25mm × 25mm 1oz Cu allows 3.9W dissipation - double the capability of standard SOT223 variants without heatsink. |
Applications
| DC-DC Buck Converter | LED Backlight Driver |
|---|---|
Use Scenario: High-efficiency 12V-to-5V step-down converter powering FPGA I/O banks. IC Role / Device Role / Timing Role: Synchronous rectifier replacing Schottky diode in low-side position to minimize conduction loss. Use Value: Achieves >94% efficiency at 3A load due to 60mΩ RDS(on) and low Qg, reducing thermal stress on PCB. | Use Scenario: Constant-current LED string driver for automotive instrument clusters. IC Role / Device Role / Timing Role: High-side PWM dimming switch controlling current through LED cathodes. Use Value: −40V VDSS accommodates battery transients; fast tf (12.54ns) ensures precise dimming resolution at 1–20kHz PWM. |
| Hot-Swap Controller | Load Switch for Industrial PLC |

Use Value: −1.0V VGS(th) enables simple resistor-divider gate bias; low Ciss ensures predictable slew rate control. | Use Scenario: Remote-controlled 12V power enable for sensor signal conditioning circuitry. IC Role / Device Role / Timing Role: Low-quiescent-current power switch isolating downstream analog sections. Use Value: 100mΩ RDS(on) at −4.5V allows direct microcontroller GPIO drive; <1µA IDSS prevents standby leakage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305UVT-7 | RDS(on) = 48mΩ @ −4.5V, but VDSS = −20V only; smaller SOT-23 package limits power handling. | Not suitable for 24V+ systems requiring 40V rating; better for space-constrained 3.3V/5V logic-level loads. | Select when board area is critical and voltage stress stays below 20V. |
| SI2301BDS-T1-GE3 | RDS(on) = 115mΩ @ −4.5V; higher thermal resistance (125°C/W); no specified Qg or tr. | Limited to lower-frequency, low-power loads (<1A); lacks dynamic specs needed for high-efficiency SMPS. | Choose only for cost-sensitive, non-switching applications like simple ON/OFF control. |
Compared with DMG2305UVT-7 and SI2301BDS-T1-GE3, ZXMP4A16GQTA uniquely balances −40V rating, 60mΩ RDS(on) at −10V, and verified 3.9W power capability - making it the only option among the three qualified for thermally demanding, 24V-class DC-DC and backlighting designs.

FAQ
What is the maximum continuous drain current for ZXMP4A16GQTA at 70°C ambient?
The maximum continuous drain current is −5.1A at TA = +70°C when mounted on FR4 PCB per Note 5 in the datasheet. This derating reflects thermal limitations of the SOT223 package under still-air conditions and requires appropriate copper area to maintain safe junction temperature.
Can ZXMP4A16GQTA be driven directly by a 3.3V microcontroller GPIO?
No - its gate threshold voltage is −1.0V, but full enhancement requires VGS ≤ −4.5V for 100mΩ RDS(on) and ≤ −10V for 60mΩ. A 3.3V GPIO cannot produce negative gate voltage; a level-shifter or inverting driver circuit is required for reliable switching.
Is ZXMP4A16GQTA qualified for automotive applications?
ZXMP4A16GQTA itself is not AEC-Q101 qualified. Diodes offers automotive-grade variants (e.g., ZXMP4A16GQTA-13) with PPAP documentation and IATF 16949 manufacturing; consult Diodes' automotive product definitions page for certified part numbers and qualification status.
What is the significance of the "Green" marking on the device top?
The "Green" marking indicates compliance with Diodes' halogen- and antimony-free definition: <900ppm bromine, <900ppm chlorine (≤1500ppm total Br+Cl), and <1000ppm antimony compounds - meeting IPC-1752A material declaration requirements for environmentally conscious electronics manufacturing.
