Product details
Overview
ZVP2120ASTZ from Zetex Semiconductors (now Diodes Incorporated) is a P-channel enhancement-mode vertical DMOS FET in TO-92 package, rated for -200 V VDS, 25 Ω RDS(on) at VGS = -10 V, and -120 mA continuous drain current. It operates across -55 °C to +150 °C and is used in high-voltage DC-DC converter feedback switches and low-power load disconnect circuits.
For engineers reviewing the ZVP2120ASTZ datasheet, ZVP2120ASTZ pinout, ZVP2120ASTZ application, or ZVP2120ASTZ equivalent, key selection criteria include verified -200 V breakdown voltage, gate-threshold range of -1.5 V to -3.5 V, pulsed current capability up to -1.2 A, and thermal stability over industrial temperature range.
Technical Context
This device uses vertical DMOS architecture optimized for high-voltage blocking with low gate charge (Qg not specified but derived from Crss/Ciss values), enabling fast switching in low-duty-cycle applications. Its -200 V BVDSS and -100 µA IDSS at -160 V confirm stable off-state leakage under elevated temperature and voltage stress.
The transconductance of 50 mS at -150 mA and -25 V VDS, combined with 100 pF Ciss and 7 pF Crss, supports predictable turn-on/turn-off timing (td(on) = 7 ns, tf = 15 ns) in discrete high-side switch configurations where gate drive voltage headroom exceeds 10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | -200 V - Sustains full reverse blocking in 170 V DC bus derated systems |
| RDS(on) | 25 Ω @ VGS = -10 V - Delivers -150 mA with ≤0.56 V drop; suitable for <100 mW load switching |
| ID Continuous | -120 mA @ Tamb = 25 °C - Requires heatsinking or derating above 60 °C ambient |
| VGS(th) | -1.5 to -3.5 V - Ensures reliable turn-on with standard logic-level negative gate drivers |
| Ciss/Coss | 100 pF / 25 pF @ VDS = -25 V - Limits switching losses in <500 kHz hard-switched topologies |
| tf/tr | 15 ns / 15 ns - Enables clean edge transitions in pulse-width modulated bias control |
Pinout & Package
Package: TO-92 (E-Line compatible, 3-pin plastic through-hole). Pin identification confirmed per Zetex Issue 2 datasheet diagram: viewed from flat side with leads down, left-to-right pin order is Drain (D), Gate (G), Source (S).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Drain | Main high-voltage current path; connected to negative rail or load return in high-side switch |
| Pin 2 (Center) | Gate | Control terminal requiring negative voltage relative to source to turn on; low input capacitance enables simple RC drive |
| Pin 3 (Right) | Source | Reference node for gate drive; tied to system ground or positive rail depending on topology |
Key Features
| Feature | Design Value |
|---|---|
| High-Voltage Blocking | -200 V VDS rating enables use in 120–170 V DC input stages without series stacking |
| Low Gate Threshold Spread | VGS(th) range (-1.5 to -3.5 V) ensures consistent turn-on across production lots with ±10% gate drive tolerance |
| Thermal Robustness | Rated for -55 °C to +150 °C junction operation - supports sealed industrial enclosures without active cooling |
| Fast Switching | 7 ns turn-on delay and 15 ns fall time allow clean PWM control at frequencies up to 1 MHz in low-current paths |
Applications
| High-Voltage Bias Switch | Low-Power Load Disconnect |
|---|---|
Use Scenario: Isolating feedback network in isolated flyback converters operating from 100–240 V AC mains. IC Role / Device Role / Timing Role: High-side P-channel switch controlling optocoupler bias current during startup and fault conditions. Use Value: -200 V rating prevents breakdown during line surges; 25 Ω RDS(on) limits quiescent loss to <0.6 mW at 100 µA bias current. | Use Scenario: Enabling/disabling auxiliary power rails in battery-backed instrumentation. IC Role / Device Role / Timing Role: Load switch isolating non-critical subsystems during deep sleep mode. Use Value: -120 mA continuous rating supports typical 50–80 mA standby loads; TO-92 footprint simplifies manual rework and prototyping. |
| Overvoltage Protection Clamp | Discrete Level Shifter |
Use Scenario: Clamping transient overvoltage on -48 V telecom supply lines. IC Role / Device Role / Timing Role: Voltage-triggered crowbar element activated by external Zener reference. Use Value: -100 µA IDSS at -160 V ensures negligible leakage during normal operation; -200 V BVDSS provides 20% margin over worst-case surge. | Use Scenario: Translating TTL/CMOS logic signals to -12 V domains in legacy test equipment. IC Role / Device Role / Timing Role: Inverting level shifter with defined threshold and rail-to-rail output swing. Use Value: -3.5 V max VGS(th) guarantees turn-on with 0 V input; 15 ns rise/fall times preserve signal integrity up to 20 MHz. |
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 |
|---|---|---|---|
| ZVP3306A | VDS = -60 V, RDS(on) = 10 Ω @ -10 V - lower voltage, lower resistance | Not suitable for >60 V blocking; better for 24 V industrial I/O | Select when system voltage ≤48 V and on-resistance <15 Ω is required |
| DMN2004LK-7 | VDS = -20 V, RDS(on) = 3.5 Ω @ -4.5 V - logic-level, much lower voltage rating | Requires gate drive ≥-4.5 V; unsuitable for any >30 V application | Choose only for low-voltage battery-powered circuits with tight gate drive constraints |
Compared with ZVP2120ASTZ, ZVP3306A trades voltage headroom for lower conduction loss in mid-range systems, while DMN2004LK-7 sacrifices blocking capability entirely for ultra-low gate drive and on-resistance-neither replicates the -200 V, TO-92, moderate-RDS(on) niche of the ZVP2120ASTZ.

FAQ
Is ZVP2120ASTZ pin-compatible with ZVP2110A?
No. ZVP2110A has identical TO-92 package but different pinout: D-S-G (left-center-right), whereas ZVP2120ASTZ is D-G-S. Swapping them causes immediate gate-source shorting. Always verify pin assignment using the "E-Line TO92 Compatible" diagram in the original Zetex datasheet.
Can ZVP2120ASTZ be driven directly from a 3.3 V microcontroller GPIO?
No. Its VGS(th) minimum is -1.5 V, but full enhancement requires VGS ≤ -10 V for 25 Ω RDS(on). A 3.3 V GPIO cannot generate sufficient negative gate voltage. Use a dedicated negative charge pump or level-shifting driver stage to achieve required -10 V gate swing.
What is the maximum safe operating area (SOA) limitation at 100 °C case temperature?
At Tc = 100 °C, derated Ptot is ~350 mW. With RDS(on) rising to ~35 Ω at 125 °C junction, maximum continuous ID drops to ~100 mA. Pulse operation must stay within the SOA curve's resistive limit line - no more than -300 mA for ≤300 µs pulses at 2% duty cycle.
Does ZVP2120ASTZ have built-in ESD protection?
No. The datasheet specifies no on-chip ESD structures. IGSS is measured at ±20 V, confirming gate oxide robustness only to that level. External 10 kΩ current-limiting resistor and 100 pF bypass capacitor are recommended at the gate to prevent handling-induced damage during PCB assembly.
