Product details
Overview
ZXM62P03GTA from Zetex is a P-channel enhancement-mode MOSFET rated for -30 V VDS, 0.15 Ω RDS(on) at -10 V VGS, and -4.0 A continuous drain current at 25°C, designed as a low-voltage power switch in DC-DC converters and motor control stages.
For engineers reviewing the ZXM62P03GTA datasheet, ZXM62P03GTA pinout, ZXM62P03GTA application, or ZXM62P03GTA equivalent, key selection criteria include its SOT223 package thermal resistance (32.2 °C/W), fast switching (td(on) = 2.8 ns), body diode recovery (trr = 19.9 ns), and gate threshold of -1.0 V.
Technical Context
This MOSFET operates in enhancement mode with negative gate-source voltage control, requiring VGS(th) ≤ -1.0 V to initiate conduction and fully enhancing at VGS = -10 V. Its trench structure enables low RDS(on) while maintaining fast dynamic performance.
It integrates a built-in body diode with VSD = -0.95 V at -1.6 A and trr = 19.9 ns under specified conditions, supporting synchronous rectification and inductive load switching without external freewheeling diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | -30 V - maximum blocking voltage in off-state, suitable for 24 V rail systems with margin |
| RDS(on) | 0.15 Ω @ VGS = -10 V, ID = -1.6 A - enables <1 W conduction loss at 2 A load |
| ID Continuous | -4.0 A @ TA = 25°C - usable in compact SOT223 power stages up to ~8 W dissipation |
| Qg | 10.2 nC - determines gate drive energy and switching speed with standard 6.2 Ω resistor |
| tr/tf | 6.4 ns / 10.3 ns - supports >10 MHz switching in high-efficiency buck regulators |
| RθJA | 32.2 °C/W - achievable with minimal copper pour; junction rises ~100°C at 3.1 W ambient dissipation |
| VGS(th) | -1.0 V - compatible with 3.3 V logic-level gate drivers when used with pull-up biasing |
Pinout & Package
SOT223 package: surface-mount, 4-pin (3 active + tab), thermally enhanced with exposed drain pad; footprint per Zetex drawing (A=6.5 mm, L=7.0 mm, E=3.0 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Reference node for gate drive; connects to load return or ground in high-side switch configuration |
| Pin 2 (Gate) | Control input | Receives negative VGS to turn on; requires stable -10 V for full RDS(on) specification |
| Pin 3 (Drain) | Power output | Connected to input rail; ties to exposed metal tab for thermal and electrical continuity |
| Tab (Drain) | Drain terminal & thermal path | Primary heat sink interface; must be soldered to ≥25 mm² 1 oz copper for RθJA = 32.2 °C/W rating |
Key Features
| Feature | Design Value |
|---|---|
| Trench process architecture | Enables 0.15 Ω RDS(on) in SOT223 - 40% lower than planar equivalents at same voltage class |
| Low gate charge (Qg = 10.2 nC) | Reduces driver power loss and enables efficient operation with low-current gate drivers |
| Fast body diode (trr = 19.9 ns) | Minimizes reverse recovery loss in synchronous buck and H-bridge motor drives |
| Low VGS(th) (-1.0 V) | Allows partial turn-on with 3.3 V logic, simplifying level-shifting in low-voltage control circuits |
| Thermally optimized SOT223 | 32.2 °C/W RθJA with minimal PCB copper - supports higher power density than SO-8 alternatives |
Applications

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 | RDS(on) = 0.045 Ω @ -4.5 V VGS; SOT-23 package; lower voltage rating (-20 V) | Better suited for 3.3 V/5 V logic-driven loads; insufficient for 24 V bus switching | Select when gate drive is limited to ≤ -4.5 V and VDS stress remains <16 V |
| SI2301DS-T1-E3 | RDS(on) = 0.115 Ω @ -4.5 V; SOT-23; Qg = 5.4 nC; lower ID (-2.7 A) | Higher switching efficiency at low current, but derates rapidly above 1.5 A due to thermal limits | Prefer for space-constrained, <1.5 A pulsed loads where gate drive is weak |
Compared with DMG2305UVT-7 and SI2301DS-T1-E3, ZXM62P03GTA delivers superior 24 V system compatibility, higher continuous current capability, and robust thermal performance in SOT223 - making it optimal for industrial DC-DC and motor control where voltage margin and power density matter.

FAQ
What is the maximum safe operating temperature for ZXM62P03GTA?
The device supports junction temperatures from -55°C to +150°C. With RθJA = 32.2 °C/W and 3.9 W power dissipation limit at 25°C ambient, sustained operation above 100°C junction requires active cooling or derating below 2.5 A continuous current.
Can ZXM62P03GTA be driven directly by a 3.3 V microcontroller GPIO?
No - its VGS(th) is -1.0 V, but full enhancement requires -10 V for 0.15 Ω RDS(on). A 3.3 V signal yields only partial turn-on (RDS(on) > 0.5 Ω). Use a dedicated gate driver or level shifter to apply sufficient negative gate voltage.
Does ZXM62P03GTA include an integrated body diode, and what are its characteristics?
Yes - it features a monolithic body diode with forward voltage VSD = -0.95 V at -1.6 A and reverse recovery time trr = 19.9 ns at 25°C. This diode is rated for continuous source current up to 2.4 A and supports inductive load commutation without external diodes.
Is the SOT223 package lead-free and RoHS compliant?
Yes - ZXM62P03GTA was manufactured to RoHS Directive 2002/95/EC compliance per Zetex documentation (Issue 2, December 2002), with lead-free terminations and halogen-free molding compound, verified via material declarations from Diodes Incorporated.
