Product details
Overview
ZXTN2005GTA from Diodes Incorporated is a 25V NPN low-saturation transistor in SOT223 package, designed for high-current switching in power electronics. It delivers 7A continuous collector current, 20A peak pulse current, and VCE(sat) ≤ 50mV at 1A-enabling efficient operation in DC-DC converters and MOSFET gate drivers.
For engineers reviewing the ZXTN2005GTA datasheet, ZXTN2005GTA pinout, ZXTN2005GTA application, or ZXTN2005GTA equivalent, key selection criteria include its 30mΩ RCE(sat) at 6.5A, hFE specified up to 20A, JEDEC-qualified reliability, and AEC-Q101 readiness for automotive-grade variants.
Technical Context
This NPN bipolar junction transistor operates with a minimum BVCEO of 25V and supports linear and switching modes up to 150°C junction temperature. Its low RCE(sat) (30mΩ @ 6.5A) and high hFE (≥200 @ 7A, ≥40 @ 20A) enable stable gain hold-up under heavy load transients.
Thermal performance is defined by RθJA = 42°C/W (52mm × 52mm 2oz Cu PCB) and RθJL = 8.8°C/W, supporting robust thermal management in compact power stages. ESD ratings meet HBM 4kV and MM 400V per JEDEC JESD22-A114/A115.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 25 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration. |
| IC (continuous) | 7 A - Sustained current-handling capability without thermal derating on standard PCB layout. |
| VCE(sat) max | 50 mV @ 1A - Enables <100mW conduction loss per device at 1A, critical for high-efficiency switching. |
| RCE(sat) | 30 mΩ @ 6.5A - Equivalent on-resistance metric enabling direct comparison with MOSFETs in low-voltage switches. |
| hFE | 40 min @ 20A - Confirmed current gain at full-rated peak current, ensuring reliable drive margin in gate driver applications. |
| fT | 150 MHz - Supports fast switching in PWM frequencies up to several MHz with minimal phase lag. |
| PD | 3.0 W - Maximum steady-state power dissipation at 25°C ambient with recommended copper layout. |
Pinout & Package
Package: SOT223 - surface-mount, 4-pin thermally enhanced plastic package with exposed collector tab (Pin 3) for low thermal resistance (RθJL = 8.8°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Emission terminal for majority carriers | Low-impedance return path; connected to ground or low-side reference in switch configurations. |
| Pin 2 (Base) | Control input for minority carrier injection | Requires ~150mA drive at 6.5A IC; compatible with standard logic-level or dedicated BJT drivers. |
| Pin 3 (Collector) | Current collection node | Exposed metal tab - must be soldered to large copper pour for thermal and electrical integrity. |
| Pin 4 (Collector) | Second collector connection | Redundant collector terminal; electrically tied to Pin 3 internally - improves current sharing and thermal spreading. |
Key Features
| Feature | Design Value |
|---|---|
| Low saturation voltage | VCE(sat) ≤ 50mV @ 1A reduces conduction losses below 50mW, improving efficiency in battery-powered systems. |
| High-current gain stability | hFE ≥ 40 @ 20A ensures predictable base drive requirements even during short-circuit or motor stall conditions. |
| Thermally optimized package | SOT223 with dual-collector pins and exposed tab achieves RθJL = 8.8°C/W - enables >2× power handling vs. standard SOT-23. |
| JEDEC-qualified reliability | Qualified to AEC-Q101 stress test standards and rated for -55°C to +150°C operation - suitable for under-hood automotive modules. |
Applications
| DC-DC Converters | MOSFET Gate Drivers |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low-saturation transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN2010GTA | Higher VCEO (30V), lower hFE (min 25 @ 20A), same SOT223 package | Better suited for 24V nominal systems requiring higher breakdown margin | Select when system bus voltage exceeds 22V and gain margin at peak current is less critical |
| MJD122G | TO-252 package, VCEO = 100V, IC = 8A, but VCE(sat) = 1.2V @ 3A - significantly higher conduction loss | Used in legacy industrial controls where board space is unconstrained and thermal mass is high | Choose only if footprint compatibility with TO-252 is mandatory and efficiency is secondary to cost |
Compared with ZXTN2010GTA and MJD122G, the ZXTN2005GTA offers optimal balance of low VCE(sat), high hFE at full current, and SOT223 thermal performance - making it preferred for space-constrained, high-efficiency 12–24V power stages.

FAQ
Is ZXTN2005GTA qualified for automotive applications?
No - the ZXTN2005GTA is not AEC-Q101 qualified. However, Diodes offers the automotive-grade ZXTN2005GQTA variant, which undergoes full AEC-Q101 stress testing, PPAP documentation, and is manufactured in IATF 16949-certified facilities. The "Q" suffix denotes automotive qualification.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is +150°C, and the device is rated for continuous operation across –55°C to +150°C. Derating begins at +25°C ambient: power dissipation drops linearly at 24mW/°C for 52mm × 52mm 2oz Cu layouts, reaching zero at ~150°C case temperature.
Can ZXTN2005GTA replace a MOSFET in low-side switching applications?
Yes - with appropriate base drive design. Its 30mΩ RCE(sat) at 6.5A matches many small-signal MOSFETs, and its 464ns toff supports PWM frequencies up to 200kHz. Unlike MOSFETs, it requires sustained base current (~150mA), so driver stage power consumption must be accounted for.
Does ZXTN2005GTA have integrated ESD protection?
Yes - it meets JEDEC JESD22-A114 (HBM) with 4,000V rating and JESD22-A115 (MM) with 400V rating. This level of on-chip ESD protection allows direct handling in standard assembly environments without additional external TVS devices for board-level ESD immunity.
