Product details
Overview
ZXTN2010GTA from Diodes Incorporated is a 60V NPN medium-power low-saturation transistor in SOT223 package, rated for 6A continuous collector current and 20A peak pulse current, with VCE(SAT) ≤ 60 mV at 1 A and RSAT = 35 mΩ at 6 A; it serves as a high-current switching element in DC motor drivers, solenoid/relay control circuits, and emergency lighting systems.
For engineers reviewing the ZXTN2010GTA datasheet, ZXTN2010GTA pinout, ZXTN2010GTA application, or ZXTN2010GTA equivalent, key selection criteria include its AEC-Q101 qualification, low on-resistance under high IC, hFE specified up to 10 A, thermal resistance of 42 °C/W (junction-to-ambient), and SOT223 lead-frame construction optimized for power dissipation in compact PCB layouts.
Technical Context
This NPN bipolar junction transistor operates with a minimum BVCEO of 60 V and supports linear and switching applications requiring stable gain up to 10 A (hFE ≥ 20 at IC = 10 A). Its low VCE(SAT) and RSAT enable efficient conduction in high-duty-cycle loads such as DC fan drivers and backlight inverters.
The device features a thermally enhanced SOT223 package with RθJL = 8.8 °C/W (junction-to-lead), enabling direct heat transfer to PCB copper; it meets J-STD-020 moisture sensitivity Level 1 and is qualified to AEC-Q101 for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum safe collector-emitter voltage before breakdown; enables use in 48 V DC systems with margin. |
| IC (continuous) | 6 A - Sustained load current capability without thermal shutdown under proper heatsinking. |
| VCE(SAT) @ 1 A | < 60 mV - Minimizes conduction loss and self-heating in high-current switching nodes. |
| RSAT @ 6 A | 35 mΩ - Equivalent on-resistance derived from VCE(SAT)/IC; critical for power budgeting in motor drive H-bridges. |
| hFE @ 10 A | ≥ 20 - Confirmed current gain at full-rated load, ensuring reliable base drive design without overdesign. |
| fT | 130 MHz - Transition frequency supporting fast switching (tON = 42 ns, tOFF = 760 ns) in PWM-controlled loads. |
| RθJA | 42 °C/W - Junction-to-ambient thermal resistance on 52 mm × 52 mm 2 oz Cu PCB; defines required board-level thermal management. |
Pinout & Package
Package: SOT223 - surface-mount, 4-terminal plastic package with exposed collector tab for thermal and electrical connection; lead-free, RoHS-compliant, halogen- and antimony-free "Green" construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Emitter terminal | Current return path; electrically isolated from tab; connects to ground or low-side reference. |
| Pin 2 (Base) | Control input | Low-impedance gate-like input requiring ~300 mA base drive at 6 A IC for saturation. |
| Pin 3 (Collector) | Main current output | Connected internally to exposed metal tab; must be soldered to large copper pour for thermal conduction. |
| Pin 4 (Collector Tab) | Collector terminal (thermal & electrical) | Primary heat path and current path; electrically identical to Pin 3; requires PCB thermal pad and solder mask opening. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade temperature cycling (-55 °C to +150 °C), vibration, and ESD robustness (HBM 4 kV). |
| Low VCE(SAT) at high IC | ≤ 100 mV at 6 A ensures < 0.6 W conduction loss, reducing thermal stress in sealed enclosures. |
| High hFE up to 10 A | Minimum hFE = 20 at IC = 10 A enables simplified base driver design with minimal external components. |
| Thermally optimized SOT223 | RθJL = 8.8 °C/W allows >2× higher power handling vs. standard SOT-23, suitable for space-constrained industrial modules. |
Applications
| Emergency Lighting Control | DC Fan Motor Driver |
|---|---|
Use Scenario: High-reliability switching of LED strings during AC mains failure, operating continuously for >90 minutes at elevated ambient temperatures. IC Role / Device Role / Timing Role: NPN power switch controlling current path between battery and LED load; operates in saturated on-state with minimal voltage drop. Use Value: Low VCE(SAT) (<60 mV @ 1 A) extends battery runtime by reducing conduction losses; AEC-Q101 rating ensures long-term stability in fire alarm systems. |
Use Scenario: PWM-driven 24 V DC cooling fan in industrial PLC cabinets where airflow must be maintained across -40 °C to +85 °C ambient range. IC Role / Device Role / Timing Role: Low-side switch modulating fan current; handles repetitive 20 A peak pulses during startup surge. Use Value: 20 A ICM rating accommodates inrush without derating; RSAT = 35 mΩ limits temperature rise to <40 °C above ambient at full load. |
| Solenoid Actuator Interface | DC-DC Module Switching Element |
Use Scenario: Driving 12 V/2 A electromagnetic solenoids in automated valve control systems deployed in factory-floor environments with EMI exposure. IC Role / Device Role / Timing Role: High-gain saturated switch providing fast turn-on/turn-off to minimize coil dwell time and reduce power consumption. Use Value: tON = 42 ns and tOFF = 760 ns enable precise 1–10 kHz PWM control; hFE ≥ 100 @ 10 mA simplifies microcontroller GPIO interface. |
Use Scenario: Secondary-side synchronous rectifier or primary-side switch in compact 12 V input, 5 V/3 A isolated DC-DC modules for medical instrumentation. IC Role / Device Role / Timing Role: Medium-power switching transistor in flyback or forward converter topologies requiring low conduction loss and thermal resilience. Use Value: 60 V VCEO supports 48 V input designs with safety margin; 3.0 W PD rating allows operation at 75% load without forced air cooling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN2020GTA | Higher VCEO = 100 V, same SOT223 package, but hFE drops to 15 @ 10 A and VCE(SAT) rises to 120 mV @ 1 A. | Better suited for 72 V bus systems; less efficient at 6 A due to higher saturation voltage. | Select when higher voltage margin is prioritized over conduction loss in battery-powered equipment. |
| MJD122G | TO-252 package, VCEO = 100 V, IC = 8 A, but RθJA = 60 °C/W and no AEC-Q101 qualification. | Larger footprint, lower thermal performance, and unqualified for automotive use. | Choose only for non-automotive, cost-sensitive designs where board area is not constrained and qualification is unnecessary. |
Compared with ZXTN2010GTA, ZXTN2020GTA trades conduction efficiency for voltage headroom, while MJD122G sacrifices thermal performance and reliability certification for raw current rating-making ZXTN2010GTA optimal for space-constrained, thermally demanding, and automotive-qualified applications.

FAQ
Is ZXTN2010GTA pin-compatible with ZXTN2020GTA?
Yes-both devices use identical SOT223 pinout (Emitter-Base-Collector-Tab) and share mechanical footprint per AP02002. However, ZXTN2020GTA exhibits higher VCE(SAT) and lower hFE at high current, so base drive and thermal design must be revalidated despite physical compatibility.
What is the maximum allowable PCB copper area for thermal performance?
Per datasheet Note 5, optimal thermal performance (RθJA = 42 °C/W) requires mounting on a 52 mm × 52 mm, 2 oz copper area on a single-sided FR4 board. Reducing copper area to 25 mm × 25 mm increases RθJA to 78 °C/W, limiting continuous IC to ~3.5 A at +70 °C ambient.
Does ZXTN2010GTA support pulsed operation beyond 6 A?
Yes-the device is rated for ICM = 20 A peak pulse current with duty cycle ≤ 2% and pulse width ≤ 300 µs. This enables short-duration surge handling in relay coil snubbing and motor stall protection, provided average power remains within 3.0 W derating limits.
Can ZXTN2010GTA replace a MOSFET in low-side switching applications?
It can functionally replace logic-level N-channel MOSFETs in low-frequency (<100 kHz), high-current DC switching where gate drive simplicity and cost matter more than ultra-low RDS(on). Unlike MOSFETs, it requires sustained base current (~300 mA at 6 A), but offers superior ruggedness against avalanche and dV/dt-induced turn-on.
