Product details
Overview
ZVP2120GTA from Diodes Incorporated is a P-channel enhancement-mode vertical DMOSFET rated for -200V drain-source voltage, 25Ω on-resistance at VGS = -10V, and -200mA continuous drain current in SOT223 package; designed for high-efficiency power management in backlighting and AC-DC converters.
For engineers reviewing the ZVP2120GTA datasheet, ZVP2120GTA pinout, ZVP2120GTA application, or ZVP2120GTA equivalent, key selection criteria include negative threshold voltage (-1.5 to -3.5V), low gate charge enabling fast switching (td(on) = 7ns), and thermal capability up to +150°C junction temperature in industrial-grade SOT223 packaging.
Technical Context
This device operates as a high-voltage, low-current P-channel switch with vertical DMOS architecture optimized for low RDS(on) while maintaining robust breakdown performance (BVDSS = -200V) and fast dynamic response (Ciss = 100pF, tr = 15ns). It uses enhancement-mode operation requiring negative gate drive relative to source.
Its gate-threshold range (-1.5V to -3.5V) ensures reliable turn-on with standard logic-level negative bias, and its -100µA IDSS at +125°C supports stable operation in elevated ambient conditions typical of enclosed power supplies and LED driver modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| BVDSS | -200V - Withstands up to -200V drain-to-source voltage before avalanche conduction begins |
| RDS(on) | 25Ω @ VGS = -10V - Low on-state resistance enables minimal conduction loss at -150mA load current |
| ID (cont) | -200mA - Continuous DC current rating at TA = +25°C with adequate PCB copper area |
| VGS(th) | -1.5 to -3.5V - Gate threshold range ensures predictable turn-on with common negative control signals |
| td(on) | 7ns - Short turn-on delay supports high-frequency switching in PWM-controlled power stages |
| Ptot | 2W - Maximum power dissipation at +25°C ambient, derated linearly above that temperature |
| Ciss | 100pF - Input capacitance determines gate drive strength requirement and switching speed limit |
Pinout & Package
Package: SOT223 (Type DN), surface-mount, 4-pin outline with exposed drain pad for thermal conduction; molded green plastic, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Reference node for gate drive; connected to positive rail in high-side P-channel configuration |
| Pin 2 (Gate) | Control input | Receives negative voltage relative to source to enable conduction; low input capacitance eases driving |
| Pin 3 (Drain) | Power output | High-voltage output node; internally connected to exposed metal pad for thermal dissipation |
| Pin 4 (Drain / Tab) | Drain terminal & thermal path | Electrically and thermally tied to drain; must be soldered to PCB copper pour for 2W operation |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) | 25Ω at -10V gate drive reduces I²R losses in low-current, high-voltage switching nodes |
| Fast switching | 7ns turn-on delay and 15ns rise time support >1MHz PWM operation in compact LED drivers |
| P-channel complement | Direct pairing with ZVN2120G enables balanced half-bridge or dual-rail control topologies |
| Green construction | Halogen- and antimony-free, RoHS 3-compliant materials meet automotive and industrial environmental mandates |
| SOT223 thermal design | Exposed drain tab allows 2W dissipation with ≥1cm² 2oz copper, simplifying thermal layout vs. SO-8 |
Applications
| LED Backlight Control | AC-DC Auxiliary Supply |
|---|---|

IC Role / Device Role / Timing Role: High-side P-channel switch controlling current flow into boost converter primary or LED string cathode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel high-voltage MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZVP3351A | BVDSS = -350V, RDS(on) = 12Ω @ -10V, ID = -150mA | Higher voltage rating but lower current; slower switching (td(on) = 12ns) | Preferred when system requires >200V blocking margin, accepts higher gate drive demand |
| DMN2053LFG-7 | BVDSS = -20V, RDS(on) = 0.12Ω @ -4.5V, ID = -4.2A | Lower voltage, much higher current, logic-level compatible | Only suitable for low-voltage (<30V) high-current loads; not interchangeable due to BVDSS mismatch |
Compared with ZVP2120GTA, ZVP3351A offers greater voltage headroom at the cost of reduced switching speed, while DMN2053LFG-7 delivers high current at low voltage but cannot replace ZVP2120GTA in -200V applications.

FAQ
What is the maximum safe operating voltage for ZVP2120GTA?
The absolute maximum drain-source voltage (BVDSS) is -200V, verified per JEDEC JESD24-10 testing. Operation beyond this rating risks avalanche breakdown and permanent damage. Derating to -160V is recommended for long-term reliability in designs without overvoltage clamping.
Can ZVP2120GTA be driven directly by a 3.3V microcontroller GPIO?
No - it requires a negative gate-source voltage to turn on. A 3.3V GPIO alone cannot produce the required -1.5V to -3.5V VGS(th); a level-shifting circuit (e.g., charge pump or dedicated gate driver like ZXGD3003E6) is necessary to generate sufficient negative gate bias relative to source.
Is ZVP2120GTA qualified for automotive use?
ZVP2120GTA is not AEC-Q101 qualified. Diodes offers automotive-grade variants (e.g., ZVP2120GQ) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation; consult Diodes' automotive product selector or local representative for qualified alternatives.
How should the SOT223 drain tab be connected on the PCB?
The exposed drain tab (Pin 4) must be soldered to a minimum 1 cm² copper pour on the PCB's top layer, thermally connected via ≥4 thermal vias to inner or bottom-layer ground/power planes. This achieves the 2W power dissipation rating; insufficient copper results in rapid thermal runaway above 1W.
