Product details
Overview
ZVNL120GTC from Diodes Incorporated is a 200V N-channel enhancement-mode MOSFET in SOT223 (Type DN) package, rated for 320mA continuous drain current at 25°C, with 10Ω RDS(on) at VGS = 5V and fast switching (tF = 12ns), designed for offline power supply start-up circuitry.
For engineers reviewing the ZVNL120GTC datasheet, ZVNL120GTC pinout, ZVNL120GTC application, or ZVNL120GTC equivalent, key selection criteria include breakdown voltage margin (200V), low-threshold gate drive (VGS(th) = 0.5–1.5V), thermal performance on FR4 (2.0W PD), and RoHS-compliant green packaging.
Technical Context
This trench-structured MOSFET delivers high-voltage blocking capability with low conduction loss and fast transient response. Its 200V VDSS, 10Ω RDS(on) at 5V gate drive, and 200mS transconductance enable efficient operation in low-power auxiliary rails.
The device operates across –55°C to +150°C junction temperature, supports ±20V gate-source rating, and exhibits low gate charge characteristics reflected in 85pF Ciss, 20pF Coss, and 7pF Crss, facilitating clean turn-on/turn-off in start-up sequencing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 200V - Withstands full mains-derived DC bus voltages in offline auxiliary supplies without avalanche stress. |
| RDS(on) | 10Ω @ VGS = 5V - Enables low-loss biasing of ICs during initial power-up before main converter engages. |
| ID (cont.) | 320mA @ TA = 25°C - Sufficient for powering startup ICs, supervisors, or small-signal controllers in <1W auxiliary rails. |
| VGS(th) | 0.5–1.5V - Compatible with low-voltage logic-level or resistor-biased gate drives in cost-sensitive start-up networks. |
| tF | 12ns - Limits switching loss and EMI during brief start-up pulse, critical for reliable IC initialization. |
| PD | 2.0W on 25mm × 25mm 1oz Cu FR4 - Supports self-heating management in compact board layouts without heatsinking. |
Pinout & Package
Package: SOT223 (Type DN), surface-mount, single-ended leadframe with exposed drain pad for thermal dissipation and mechanical anchoring.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | Main current path output terminal | Connected to high-voltage rail (e.g., rectified AC line); electrically and thermally coupled to exposed pad. |
| Source (S) | Reference node for gate control and current return | Typically tied to ground or controller reference; forms common node for gate drive loop. |
| Gate (G) | Control electrode for channel modulation | High-impedance input requiring minimal drive current; sensitive to ESD and noise due to low VGS(th). |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage blocking | 200V VDSS enables direct connection to unregulated DC bus up to 160V after rectification. |
| Low-threshold gate drive | VGS(th) as low as 0.5V allows activation using simple resistor-divider or zener-clamped bias networks. |
| Fast switching | 8ns tR/tD(on) and 12ns tF reduce transition losses during short-duration start-up pulses. |
| Green packaging | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets IEC 61249-2-21. |
Applications
| AC-DC Adapter Auxiliary Supply | Industrial PLC Power Sequencing |
|---|---|
Use Scenario: Provides regulated 12V bias to PWM controller during initial AC line connection before main transformer energizes. IC Role / Device Role / Timing Role: High-side switch enabling controlled power ramp to supervisor IC and gate driver. Use Value: Prevents uncontrolled inrush by delaying main converter enable until stable VCC is established. |
Use Scenario: Powers watchdog timer and FPGA configuration circuitry during cold-start of programmable logic controller. IC Role / Device Role / Timing Role: Low-duty-cycle start-up switch delivering burst current to reset sequencer and clock generator. Use Value: Ensures deterministic boot state by isolating auxiliary rail until primary 24V supply reaches regulation. |
| Smart Meter Power Management | LED Driver Standby Circuit |
Use Scenario: Supplies real-time clock and metrology ASIC from rectified line during meter sleep mode. IC Role / Device Role / Timing Role: Always-on, low-quiescent switch maintaining backup power path independent of main DC-DC. Use Value: Maintains timekeeping and tamper detection with <100µA standby leakage (IDSS ≤ 10µA). |
Use Scenario: Energizes LED driver IC only when ambient light sensor detects darkness, reducing no-load consumption. IC Role / Device Role / Timing Role: Enable-controlled MOSFET acting as power gate between bulk capacitor and driver IC input. Use Value: Achieves <0.3W standby power by eliminating quiescent draw from driver IC when inactive. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, low-current MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZVN2120A | 200V VDSS, 12Ω RDS(on) @ 10V, higher VGS(th) (1.0–2.5V) | Requires stronger gate drive; less suitable for weak-bias start-up networks | Prefer where gate voltage exceeds 6V and layout permits slightly higher on-resistance. |
| DMN2004LK3 | 200V VDSS, 8.5Ω RDS(on) @ 10V, SOT-23 package (lower PD = 0.7W) | Limited thermal capacity; unsuitable for sustained 300mA loads | Select only for space-constrained designs with pulsed duty cycles <10% and ambient <60°C. |
Compared with ZVNL120GTC, ZVN2120A offers tighter VGS(th) tolerance but demands higher gate voltage, while DMN2004LK3 improves RDS(on) at the expense of thermal derating-making ZVNL120GTC optimal for thermally constrained, low-duty-cycle start-up functions.

FAQ
What is the maximum safe operating voltage for ZVNL120GTC in continuous DC applications?
The absolute maximum drain-source voltage is 200V per datasheet DS33388 Rev. 4-2. For reliable long-term operation, design margins should limit steady-state VDS to ≤160V to accommodate transients and ensure zero avalanche stress under worst-case conditions including line surges and ringing.
Can ZVNL120GTC be driven directly from a 3.3V microcontroller GPIO?
Yes - its VGS(th) range (0.5–1.5V) ensures turn-on with 3.3V drive, and RDS(on) remains ≤10Ω at VGS = 3V (ID = 125mA). However, gate series resistance ≥100Ω is recommended to dampen ringing and limit peak current during fast edge transitions.
Is ZVNL120GTC qualified for automotive use per AEC-Q101?
No - the ZVNL120GTC is not AEC-Q101 qualified. Diodes explicitly states that automotive-grade versions require separate part numbers (e.g., ZVNL120QTC) and PPAP-capable manufacturing in IATF 16949 facilities; this variant is intended for industrial and consumer power applications.
How does the SOT223 (Type DN) package affect thermal performance compared to standard SOT223?
The Type DN variant uses a modified leadframe with enhanced thermal pad geometry and matte tin annealed finish, achieving 2.0W power dissipation on 25mm × 25mm 1oz Cu FR4 - 0.5W higher than baseline SOT223 - due to improved copper-to-PCB interface and reduced thermal resistance from junction to case (RθJC ≈ 45°C/W).
