Product details
Overview
ZXMP2120G4TA from Diodes Incorporated is a 200V P-channel enhancement-mode MOSFET in SOT223 package, featuring 25Ω RDS(ON) at VGS = −10V, −200mA continuous drain current, and fast switching (tF = 15ns). It serves as a high-voltage active clamp switch in 48V DC-DC converter primary-side circuits.
For engineers reviewing the ZXMP2120G4TA datasheet, ZXMP2120G4TA pinout, ZXMP2120G4TA application, or ZXMP2120G4TA equivalent, key selection criteria include negative threshold voltage (−1.5 to −3.5V), low gate charge suitability for low-power drive, body diode recovery performance in clamping topologies, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This trench-structured P-channel MOSFET operates with depletion-free enhancement mode, requiring negative gate-source bias for conduction. Its −200V VDSS rating and −100µA IDSS at 125°C support robust blocking in high-side clamp configurations where voltage transients exceed 150V.
The device delivers 50mS transconductance at −25V VDS and −150mA ID, enabling precise gate-controlled current regulation. Its Ciss/Coss/Crss values (100pF/25pF/7pF) yield low capacitive switching losses ideal for >100kHz DC-DC operation with minimal Miller effect.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −200V: Withstands 200V reverse drain-source voltage before avalanche breakdown, enabling use in 48V bus systems with ≥4× transient margin. |
| RDS(ON) | 25Ω @ VGS = −10V: Delivers <100mW conduction loss at −150mA, suitable for low-duty-cycle clamp switches. |
| ID (cont) | −200mA @ TA = +25°C: Supports peak clamp currents up to 200mA without derating on standard FR4 PCBs. |
| VGS(TH) | −1.5 to −3.5V: Ensures reliable turn-on with logic-level gate drivers (e.g., −5V or −3.3V rails) while avoiding false triggering. |
| tF | 15ns: Enables fast turn-off critical for minimizing energy dissipation during voltage spike suppression in flyback/snubber circuits. |
| Ciss | 100pF @ VDS = −25V: Low input capacitance reduces gate drive power and improves switching speed stability across temperature. |
| PD | 2.0W @ TA = +25°C: Sustains 2W dissipation on 25mm × 25mm 1oz copper PCB, supporting intermittent high-power clamping pulses. |
Pinout & Package
SOT223 package: surface-mount, 4-pin thermally enhanced plastic case with exposed drain tab (pin 4), matte tin terminals, UL 94V-0 rated molding compound, and 0.112g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal accepting negative VGS to modulate channel conductivity; low 20nA leakage ensures stable off-state. |
| 2 (S) | Source | Reference node for gate drive; connected to high-side rail in active clamp topologies to enable negative VGS bias. |
| 3 (D) | Drain | Main current path; electrically tied to exposed metal tab (pin 4) for thermal conduction to PCB copper pour. |
| 4 (D) | Drain (Tab) | Thermal and electrical connection to drain; must be soldered to ≥25mm² copper area for RθJA = 62.5°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage blocking | −200V VDSS enables direct integration into 48V industrial and automotive DC-DC converters without external voltage dividers. |
| Low gate threshold spread | −1.5 to −3.5V VGS(TH) ensures consistent turn-on across temperature and process variation, reducing timing jitter in clamp control loops. |
| Fast body diode recovery | Integrated source-drain diode with 15ns tF supports synchronous rectification and bidirectional current handling in resonant topologies. |
| AEC-Q101 qualification | Qualified for automotive applications per AEC-Q101 Rev D, including HTGB, HTRB, and TC testing, ensuring reliability in under-hood environments. |
| Green packaging | Halogen- and antimony-free molding compound (<900ppm Br+Cl, <1000ppm Sb) meets EU RoHS 2 and automotive environmental compliance mandates. |

IC Role / Device Role / Timing Role: High-reliability P-channel clamp placed across relay/solenoid coil to absorb stored magnetic energy during deactivation. Use Value: Extends solenoid lifetime by eliminating arcing and reduces EMI emissions by 15dB compared to RC snubbers. | Use Scenario: Protects digital I/O channels in programmable logic controllers against field-wiring faults and electrostatic discharge in factory automation. IC Role / Device Role / Timing Role: Bidirectional transient suppressor leveraging intrinsic body diode and controlled RDS(ON) to clamp ±200V surges without latch-up. Use Value: Maintains I/O functionality after 10kV ESD contact discharge (IEC 61000-4-2 Level 4) with no parameter shift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2016LFG-7 | Lower VDSS (−20V), lower RDS(ON) (16mΩ), SOT23 package | Not suitable for 48V+ clamping; limited to ≤24V logic-level loads | Select only for low-voltage, high-current switching where thermal budget permits smaller package. |
| SI2301DS-T1-BE3 | −20V VDSS, 115mΩ RDS(ON), SOT23-3 package | Lacks AEC-Q101 qualification and high-voltage capability; unsuitable for automotive clamp roles | Use only in cost-sensitive consumer applications below 12V with minimal surge requirements. |
Compared with DMN2016LFG-7 and SI2301DS-T1-BE3, ZXMP2120G4TA uniquely combines −200V blocking, AEC-Q101 qualification, and SOT223 thermal performance-making it irreplaceable for 48V+ active clamp designs requiring automotive reliability and transient robustness.

FAQ
What is the maximum safe operating junction temperature for ZXMP2120G4TA?
The absolute maximum junction temperature is +150°C, with continuous operation recommended up to +125°C ambient when mounted on a 25mm × 25mm 1oz copper PCB. Thermal derating begins at 62.5°C/W above +25°C ambient, requiring thermal design validation for sustained >1W dissipation.
Can ZXMP2120G4TA be driven directly from a 3.3V microcontroller GPIO?
No-its VGS(TH) range (−1.5 to −3.5V) requires negative gate bias relative to source. A level-shifting circuit or dedicated P-channel gate driver (e.g., TC4427 configured for high-side drive) is mandatory to achieve full enhancement and avoid linear-region operation.
Is the SOT223 drain tab electrically isolated from other pins?
No-the exposed drain tab (pin 4) is internally connected to the drain terminal (pin 3). It must be soldered to a PCB copper pour designated as the drain net and thermally coupled to ground or high-side rail depending on circuit topology to ensure proper heat dissipation and electrical integrity.
Does ZXMP2120G4TA include integrated ESD protection on its gate?
No-this MOSFET lacks on-chip gate protection diodes. External 10kΩ series gate resistor and 10V Zener clamp between gate and source are required to prevent ESD damage during handling and PCB assembly, especially in automated manufacturing environments.
