Product details
Overview
ZVN4306ASTZ from Diodes Incorporated is a 60V N-channel enhancement-mode vertical DMOS FET in E-Line (TO-92 compatible) package, rated for 1.1A continuous drain current, 330mΩ RDS(ON) at VGS = 10V, and 850mW power dissipation - used as a low-side switch in automotive solenoid drivers and DC-DC converter synchronous rectification stages.
For engineers reviewing the ZVN4306ASTZ datasheet, ZVN4306ASTZ pinout, ZVN4306ASTZ application, or ZVN4306ASTZ equivalent, key selection criteria include verified BVDSS ≥ 60V, RDS(ON) ≤ 0.33Ω at 10V drive, thermal resistance RθJA = 150°C/W on standard FR-4, gate threshold voltage range (1.3–3.0V), and E-Line mechanical compatibility with legacy TO-92 footprints.
Technical Context
This discrete MOSFET operates in enhancement mode with a vertically structured DMOS cell, enabling stable conduction under pulsed drain currents up to 15A and gate-source voltage tolerance of ±20V. Its 1.3–3.0V VGS(TH) ensures reliable turn-on with standard 3.3V/5V logic-level drive in low-power control circuits.
Thermal performance is defined for two mounting conditions: RθJA = 150°C/W on 25mm × 25mm × 1.6mm FR-4 with single-sided 1oz copper, and RθJL = 50°C/W to solder point - critical for thermally constrained PCB layouts in automotive body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60V - supports 48V automotive rail switching without avalanche stress |
| RDS(ON) | 330mΩ @ VGS = 10V - limits I²R loss to ≤ 510mW at 1.2A load |
| ID (continuous) | 1.1A - defines maximum steady-state current in non-pulsed operation |
| PD | 850mW - sets thermal derating limit on standard FR-4 board |
| VGS(TH) | 1.3–3.0V - ensures turn-on with 3.3V microcontroller GPIO without level-shifting |
| Ciss | 350pF - determines gate drive energy requirement (~1.75µC at 10V) |
| tF | 16ns - enables ≤ 2MHz switching in low-duty-cycle PWM applications |
Pinout & Package
E-Line (TO-92 compatible) package with matte tin-plated terminals, molded green plastic housing (UL 94V-0), and 0.159g mass. Pin identification is bottom-view: Drain (D), Source (S), Gate (G) - arranged linearly with D at left, S center, G right when flat side faces viewer and leads point downward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Drain) | High-side connection to load supply rail | Carries full switched current; electrically isolated from package tab (no heatsink pad) |
| S (Source) | Return path to ground or low-side reference | Reference node for gate drive; ties directly to PCB ground plane for stability |
| G (Gate) | Control input for channel conduction | High-impedance node requiring <100nA leakage budget; sensitive to ESD per ±20V rating |
Key Features
| Feature | Design Value |
|---|---|
| Breakdown voltage > 60V | Guarantees safe operation across 48V automotive transients (ISO 7637-2 Pulse 5a) |
| RDS(ON) ≤ 0.33Ω @ 10V | Enables use with standard logic-level microcontrollers without gate drivers |
| JEDEC-qualified high reliability | Validated per AEC-Q101 stress test requirements for discrete semiconductors |
| Halogen- and antimony-free "Green" construction | Meets EU RoHS 3 (2015/863/EU) with Br+Cl <1500ppm and Sb <1000ppm |
| E-Line mechanical compatibility | Direct drop-in replacement for legacy TO-92 N-channel FETs in existing footprints |
Applications
| Automotive Solenoid Driver | DC-DC Converter Synchronous Rectifier |
|---|---|
Use Scenario: Driving 12V/24V fuel injector or HVAC flap actuator solenoids in body control modules. IC Role / Device Role / Timing Role: Low-side switch controlling coil energization/de-energization timing with fast fall time (16ns). Use Value: 60V BVDSS withstands load-dump transients; 1.1A ID supports typical 0.8–1.0A solenoid hold current. | Use Scenario: Replacing Schottky diode in 5–12V buck converter output stage for improved efficiency. IC Role / Device Role / Timing Role: Synchronous rectifier conducting during low-side switch conduction phase. Use Value: 330mΩ RDS(ON) reduces conduction loss by ~40% vs. 0.5V-drop Schottky at 1A. |
| Industrial Relay Interface | Low-Power LED String Switch |
Use Scenario: Isolating PLC output signals to control 24V industrial relays in factory automation panels. IC Role / Device Role / Timing Role: Logic-level controlled power switch interfacing microcontroller GPIO to relay coil. Use Value: 1.3–3.0V VGS(TH) ensures turn-on with 3.3V MCU outputs; 15A pulsed rating handles relay inrush. | Use Scenario: Dimming or on/off control of 5–12V LED arrays in signage or instrumentation backlighting. IC Role / Device Role / Timing Role: Constant-current or PWM-controlled current sink for LED string cathode. Use Value: 850mW PD allows 1.1A continuous at ambient ≤ 50°C; 350pF Ciss supports 1–5kHz PWM dimming. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZVN3310F | Lower VDSS (30V), lower RDS(ON) (150mΩ), same E-Line package | Not suitable for 48V systems; limited to 24V industrial/LED applications | Select only if operating voltage ≤ 24V and lower on-resistance is prioritized |
| DMN2053UVT | Higher VDSS (200V), SOT-23 package, 2.5A ID, 200mΩ RDS(ON) | Surface-mount alternative with higher voltage margin but no TO-92 footprint compatibility | Choose for space-constrained designs needing >60V headroom and SMT assembly |
Compared with ZVN4306ASTZ, ZVN3310F trades voltage capability for lower conduction loss in 24V systems, while DMN2053UVT offers higher voltage margin and current rating in a smaller SMT package - neither replicates the exact 60V/E-Line/1.1A balance of the original.

FAQ
Is ZVN4306ASTZ qualified for automotive applications?
No - ZVN4306ASTZ is not AEC-Q101 qualified. Diodes offers automotive-grade equivalents with Q-suffix (e.g., ZVN4306AQ) that undergo additional stress testing, PPAP documentation, and IATF 16949 manufacturing controls. This part meets JEDEC high-reliability standards but lacks automotive-specific qualification.
What is the maximum gate drive voltage for ZVN4306ASTZ?
The absolute maximum gate-source voltage (VGS) is ±20V. Operation above +12V or below –12V risks oxide damage. Recommended drive is +10V for full RDS(ON) specification; +5V yields 450mΩ RDS(ON) and is sufficient for many 5V logic-driven loads.
Can ZVN4306ASTZ replace a bipolar transistor in relay driver circuits?
Yes - its 1.1A continuous current and 15A pulsed rating support typical relay coil inrush (3–5× hold current). Unlike BJTs, it requires no base current, eliminates saturation voltage loss, and provides faster switching (tF = 16ns), reducing relay contact arcing and improving lifetime in high-cycle applications.
Why does the datasheet state "NOT RECOMMENDED FOR NEW DESIGNS"?
Diodes has superseded ZVN4306ASTZ with newer-generation E-Line FETs offering lower RDS(ON), higher current, or enhanced automotive qualification. While fully functional and supported, new designs should evaluate alternatives like ZVN4306AQ (AEC-Q101) or ZVN3310F (lower RDS(ON)) unless legacy compatibility is mandatory.
