Product details
Overview
VN10LPSTOA from Diodes Incorporated is a 60V N-channel enhancement-mode vertical DMOSFET in E-Line (TO-92 compatible) package, rated for 270mA continuous drain current, 5.0Ω RDS(ON) at VGS = 10V, and 625mW power dissipation. It serves as a low-voltage logic-level switch in space-constrained consumer and industrial control circuits.
For engineers reviewing the VN10LPSTOA datasheet, VN10LPSTOA pinout, VN10LPSTOA application, or VN10LPSTOA equivalent, key selection criteria include its 60V VDSS, 0.8–2.5V gate threshold, 10ns switching times, thermal resistance of 200°C/W, and suitability for low-duty-cycle load switching in battery-powered systems.
Technical Context
This discrete MOSFET uses vertical DMOS architecture to achieve high breakdown voltage with low on-resistance in a through-hole E-Line package. Its gate threshold range (0.8–2.5V) enables direct drive from 3.3V/5V logic, while pulsed drain current capability up to 3A supports transient load handling.
Thermal design relies on junction-to-ambient resistance of 200°C/W under standard FR4 mounting, and junction-to-leads resistance of 71°C/W - critical for lead-solder-point thermal management in non-heatsinked applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum blocking voltage before avalanche conduction; defines safe operating range in 24V/48V supply rails. |
| RDS(ON) | 5.0 Ω @ VGS = 10V - On-state resistance determines I²R conduction loss at 270mA; yields ~365mW dissipation at full current. |
| ID (cont.) | 270 mA - Continuous DC current rating under 25°C ambient and specified PCB layout; derates above 25°C per RθJA. |
| tON/tOFF | 10 ns each - Fast switching enables use in PWM-driven LED dimming or relay drivers below 1MHz. |
| VGS(TH) | 0.8–2.5 V - Gate turn-on threshold ensures compatibility with 3.3V microcontroller GPIO without level-shifting. |
| PD | 625 mW - Power dissipation limit at 25°C ambient; requires thermal pad area or airflow if sustained near max current. |
| Ciss | 60 pF - Input capacitance affects gate drive strength requirements; compatible with low-current logic drivers. |
Pinout & Package
Package: E-Line (TO-92 compatible), molded plastic with matte tin-plated leads, UL 94V-0 rated, weight ≈ 0.159 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control electrode | Accepts logic-level voltage (0.8–2.5V threshold); requires <100nA leakage current compliance. |
| D (Drain) | High-side current path | Connected to load supply rail; handles up to 60V reverse bias and 3A pulsed current. |
| S (Source) | Reference node | Typically tied to ground or low-side return; establishes VGS reference for gate drive. |
Key Features
| Feature | Design Value |
|---|---|
| Lead-free & RoHS 3 compliant | Fully compliant with EU Directive 2015/863/EU; no intentionally added lead, halogen, or antimony. |
| JEDEC High Reliability qualification | Qualified to JEDEC standards referenced in AEC-Q series; suitable for industrial-grade reliability requirements. |
| Low gate charge & fast switching | 10ns tON/tOFF with 60pF Ciss enables efficient PWM operation without excessive gate driver loading. |
| Thermally optimized lead-frame | RθJL = 71°C/W enables localized heat transfer to PCB copper via drain lead solder joint. |
Applications
| LED Indicator Control | Low-Power Sensor Interface |
|---|---|
Use Scenario: Driving discrete status LEDs in portable instrumentation with 3.3V MCU GPIO. IC Role / Device Role / Timing Role: Low-side switch controlling LED anode-to-VCC path; operates in DC or 1kHz PWM mode. Use Value: 270mA rating supports multi-LED strings; 5Ω RDS(ON) limits voltage drop to <1.4V at 270mA, preserving LED forward margin. | Use Scenario: Enabling/disabling analog sensor supply rails (e.g., temperature or humidity sensors) during sleep cycles. IC Role / Device Role / Timing Role: Power-gating FET isolating sensor VDD from main 5V rail; controlled by MCU wake signal. Use Value: Sub-µA IDSS (<10µA) prevents standby current leakage; 0.8V VGS(TH) ensures reliable turn-on from weak-pull GPIO. |
| Relay Driver Circuit | Small-Signal Load Switch |
Use Scenario: Replacing bipolar transistor in coil-driver stage for 5V/12V signal relays in PLC I/O modules. IC Role / Device Role / Timing Role: Saturated switch providing >100mA coil current with minimal saturation voltage. Use Value: 5Ω RDS(ON) yields <500mV VDS at 100mA - lower than typical BJT VCE(sat), reducing heat in compact enclosures. | Use Scenario: Isolating auxiliary circuitry (e.g., display backlight, buzzer) in battery-powered medical devices. IC Role / Device Role / Timing Role: Single-pole, single-throw (SPST) power switch activated by system controller. Use Value: TO-92 footprint allows manual assembly or wave-soldering; 625mW PD supports intermittent 200mA loads without heatsinking. |
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 |
|---|---|---|---|
| ZVN2110A | RDS(ON) = 6.5Ω @ VGS = 10V; VDSS = 60V; TO-92 package | Higher on-resistance increases conduction loss by ~30% at 200mA | Acceptable where thermal margin exists and cost sensitivity outweighs efficiency. |
| BS170 | RDS(ON) = 5.0Ω @ VGS = 10V; VDSS = 60V; TO-92 package; VGS(TH) = 0.8–3.0V | Broadened VGS(TH) range reduces guaranteed turn-on certainty at 3.3V | Use only with verified 5V gate drive or external pull-up; not recommended for 3.3V-only systems. |
Compared with ZVN2110A and BS170, VN10LPSTOA offers tighter VGS(TH) control and lower thermal resistance (RθJA = 200°C/W vs. 250°C/W typical for BS170), enabling more robust operation in thermally constrained 3.3V designs.

FAQ
Is VN10LPSTOA pin-compatible with standard TO-92 transistors?
Yes - VN10LPSTOA uses the E-Line package, which is mechanically identical to TO-92 (flat-face view: G-D-S left-to-right). Pin spacing, lead diameter, and body dimensions match JEDEC TO-92 standards, enabling direct replacement in existing through-hole layouts without footprint modification.
What is the maximum safe operating temperature for VN10LPSTOA?
The device supports junction temperatures from –55°C to +150°C. At 25°C ambient, continuous operation at 270mA requires ≤625mW dissipation. With RθJA = 200°C/W, junction temperature rises ~55°C at full current - staying within safe limits. Derating is required above 25°C ambient per the thermal curve in DS33198.
Can VN10LPSTOA be driven directly from a 3.3V microcontroller GPIO?
Yes - its VGS(TH) range (0.8–2.5V) guarantees turn-on with 3.3V drive. At VGS = 3.3V, RDS(ON) is higher than at 10V but still sufficient for ≤100mA loads. For full 270mA performance, 5V or higher gate drive is recommended per datasheet test conditions.
Why is VN10LPSTOA marked "not recommended for new designs"?
Diodes has issued this notice due to planned obsolescence or newer-generation replacements (e.g., enhanced RDS(ON), lower Qg, or SOT-23 variants). Existing designs may continue using it, but new projects should consult Diodes' latest portfolio or contact Aetrix for qualified alternatives with extended lifecycle support.
