Product details
Overview
ZVN3306ASTZ from Zetex Semiconductors (now Diodes Incorporated) is an N-channel enhancement-mode vertical DMOS FET in TO-92 package, rated for 60 V VDS, 5 Ω RDS(on) at VGS = 10 V and ID = 500 mA, with 270 mA continuous drain current at 25°C ambient - used in low-power switching and load control circuits such as LED drivers and relay drivers.
For engineers reviewing the ZVN3306ASTZ datasheet, ZVN3306ASTZ pinout, ZVN3306ASTZ application, or ZVN3306ASTZ equivalent, key selection criteria include verified RDS(on) at 10 V gate drive, guaranteed 60 V breakdown margin, TO-92 thermal derating behavior, and gate threshold voltage range (0.8–2.4 V) for TTL/CMOS-compatible drive.
Technical Context
This discrete MOSFET operates in enhancement mode with a vertically structured DMOS cell, enabling higher current density and lower on-resistance than planar counterparts of similar die size. Its gate threshold voltage (0.8–2.4 V) ensures reliable turn-on with standard logic-level signals, while the 5 Ω RDS(on) supports efficient switching up to 500 mA DC load current.
The device exhibits fast switching performance: 5 ns turn-on delay, 7 ns rise time, 6 ns turn-off delay, and 8 ns fall time under VDD ≈ 18 V and ID = 500 mA conditions. Input capacitance (Ciss = 35 pF) and reverse transfer capacitance (Crss = 8 pF) are optimized for low-noise, medium-speed digital switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 60 V - supports operation across 24 V industrial rails and 48 V telecom systems with safety margin |
| RDS(on) | 5 Ω @ VGS = 10 V, ID = 500 mA - enables <1.25 W conduction loss at 500 mA, suitable for thermally constrained PCBs |
| ID continuous | 270 mA @ Tamb = 25°C - defines maximum steady-state load current without heatsinking |
| VGS(th) | 0.8–2.4 V @ ID = 1 mA - ensures compatibility with 3.3 V and 5 V logic outputs without level shifting |
| Ptot | 625 mW @ Tamb = 25°C - sets thermal limit for TO-92 package in still-air environments |
| Ciss | 35 pF @ VDS = 18 V - determines gate drive energy requirement and switching speed sensitivity to driver impedance |
| gfs | 150 mS @ VDS = 18 V, ID = 500 mA - quantifies transconductance for analog gain or linear-region control use cases |
Pinout & Package
Package: TO-92 (E-Line compatible), through-hole, 3-pin plastic case with standard lead spacing and thermal profile per JEDEC TO-92 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | High-side current path output | Connected to load return or supply rail; carries full switched current and must be routed with adequate copper area for thermal dissipation |
| Gate (G) | Control input terminal | High-impedance MOS gate requiring low-capacitance drive; sensitive to ESD and requires series resistor for ringing suppression |
| Source (S) | Reference node / current return | Typically tied to ground or low-side reference; establishes VGS bias and serves as common return for gate drive circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Vertical DMOS structure | Enables lower RDS(on) per unit die area vs. planar MOSFETs, improving power efficiency in compact TO-92 footprint |
| Guaranteed 60 V VDS | Provides robust overvoltage tolerance in 24–48 V systems, reducing need for external clamping components |
| TTL/CMOS-compatible VGS(th) | Ensures reliable turn-on with standard microcontroller GPIO or logic buffers without gate driver ICs |
| Fast switching times (≤8 ns) | Supports PWM frequencies up to ~20 MHz in low-duty-cycle applications with minimal switching loss |
| −55°C to +150°C operating range | Validates use in automotive under-hood, industrial control, and outdoor equipment environments |
Applications
| LED Driver Circuits | Relay Driver Stages |
|---|---|
Use Scenario: Driving 20–100 mA indicator LEDs or 350 mA high-brightness LEDs from MCU GPIO pins. IC Role / Device Role / Timing Role: Low-side switch controlling LED cathode connection to ground. Use Value: 5 Ω RDS(on) limits voltage drop to ≤500 mV at 100 mA, preserving forward voltage headroom and brightness consistency. | Use Scenario: Switching 12–24 VDC coil relays with 50–200 mA holding current in PLC I/O modules. IC Role / Device Role / Timing Role: Solid-state replacement for mechanical relay contacts in control logic outputs. Use Value: 60 V VDS rating safely absorbs relay coil flyback spikes up to 50 V without snubber diodes. |
| Low-Power Load Switches | Microcontroller Peripheral Drivers |
Use Scenario: Enabling/disabling 3.3 V or 5 V peripheral rails (e.g., sensors, transceivers) in battery-powered IoT nodes. IC Role / Device Role / Timing Role: High-side or low-side power switch controlled by MCU enable signal. Use Value: 270 mA continuous rating supports typical sensor clusters; 625 mW Ptot allows direct PCB mounting without heatsink. | Use Scenario: Driving small solenoids, buzzers, or optocoupler inputs from embedded microcontrollers. IC Role / Device Role / Timing Role: General-purpose digital output buffer with current amplification. Use Value: 0.8–2.4 V VGS(th) ensures turn-on with 3.3 V logic; fast 7 ns rise time supports clean edge integrity in timing-critical interfaces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel low-voltage switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZVN3310A | Higher VDS (100 V), same TO-92 package, RDS(on) = 7 Ω @ 10 V | Better surge immunity but higher conduction loss at same current | Select when system transient voltage exceeds 60 V but space constraints require TO-92 |
| 2N7002 | Lower ID (300 mA), smaller SOT-23 package, RDS(on) = 5.5 Ω @ 10 V | Surface-mount only; unsuitable for through-hole assembly or higher thermal mass needs | Select for automated assembly and board space savings where 270 mA rating is sufficient |
Compared with ZVN3306ASTZ, ZVN3310A trades higher voltage capability for increased on-resistance, while 2N7002 offers SMT compatibility at the cost of reduced thermal mass and lower peak current handling - choice depends on assembly method, voltage stress, and thermal design priority.

FAQ
Is ZVN3306ASTZ suitable for PWM dimming of LEDs?
Yes - its 7 ns rise time and 8 ns fall time support PWM frequencies up to 10–20 MHz in low-duty-cycle operation, and its 5 Ω RDS(on) minimizes conduction loss during active periods. Thermal performance in TO-92 requires limiting average current to ≤200 mA for sustained 100% duty cycle.
What is the maximum safe gate-source voltage for ZVN3306ASTZ?
The absolute maximum VGS is ±20 V per datasheet. Operation above ±12 V provides no benefit and risks gate oxide damage; recommended drive is 5–10 V for optimal RDS(on) and reliability. A 10 kΩ series gate resistor is advised to suppress ringing.
Can ZVN3306ASTZ replace a bipolar transistor like BC547 in switching applications?
Yes - its logic-level VGS(th) and low RDS(on) allow direct replacement without base resistors, reducing component count. Unlike BC547, it draws negligible gate current, eliminating base drive power loss and simplifying MCU interface design.
Does ZVN3306ASTZ have built-in ESD protection?
No - the device lacks integrated ESD protection diodes. Gate-source leakage is specified at 20 nA at ±20 V, confirming absence of internal clamps. External 10 kΩ gate pull-down and TVS diode on drain are recommended in high-noise environments.
