Product details
Overview
ZXTN2011GTA from Diodes Incorporated is a 100V NPN medium-power low-saturation transistor in SOT223 package, rated for 6A continuous collector current and 10A peak pulse current, with VCE(sat) ≤ 65mV at 1A and on-resistance RSAT = 36mΩ at 6A; used in high-side switching, DC motor drives, and SLIC applications.
For engineers reviewing the ZXTN2011GTA datasheet, ZXTN2011GTA pinout, ZXTN2011GTA application, or ZXTN2011GTA equivalent, key selection criteria include guaranteed hFE up to 10A, AEC-Q101 qualification, thermal resistance RθJA = 42°C/W (on 52mm × 52mm 2oz copper), and low VCE(sat) under high-current switching conditions.
Technical Context
This NPN bipolar junction transistor operates as a high-voltage, high-current switch with BVCEO = 100V and BVCBO = 200V, enabling robust line-switching in industrial power supplies and telecom interfaces. Its fT = 130MHz supports fast turn-on/turn-off transitions.
The device delivers stable gain across temperature (hFE = 20–230 at IC = 10mA–10A) and maintains low saturation voltage down to –55°C, verified by pulsed testing (≤300µs, ≤2% duty cycle). Thermal design relies on RθJL = 8.8°C/W to solder point for lead-mounted dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100V - enables use in 48V telecom and 24V industrial bus systems without derating |
| IC (cont.) | 6A - supports continuous DC fan and solenoid loads without forced cooling |
| VCE(sat) | ≤65mV @ 1A - reduces conduction loss to <65mW, critical for thermally constrained PCB layouts |
| RSAT | 36mΩ @ 6A - provides predictable on-state resistance for accurate power loss modeling |
| hFE | 20–230 (IC = 10mA–10A) - ensures reliable base drive margin across full load range |
| fT | 130MHz - supports switching frequencies up to ~10MHz with controlled rise/fall times |
| RθJA | 42°C/W - defines maximum power dissipation of 3.0W at TA = 25°C on standard 52mm × 52mm 2oz copper |
Pinout & Package
Package: SOT223 - surface-mount plastic package with exposed collector tab for thermal conduction; 0.112g weight; UL 94V-0 rated molding compound; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Emitter terminal | Current return path; electrically isolated from tab; requires proper grounding for safe operation |
| Pin 2 (Base) | Control input | Low-impedance gate for BJT switching; requires IB = 100mA to saturate at IC = 1A |
| Pin 3 (Collector) | Power output / heat sink | Connected to exposed metal tab; primary thermal path to PCB copper; must be soldered to ≥52mm² 2oz copper |
| Pin 4 (Collector Tab) | Collector extension | Not electrically isolated; same potential as Pin 3; mandatory for thermal performance and SOA compliance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM 4kV) |
| Low VCE(sat) at high current | 65mV max @ 1A enables <100mW conduction loss in compact motor driver stages |
| High-current hFE specification | hFE ≥20 at IC = 10A ensures stable base drive design without overdesigning driver stage |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets IPC-1752A reporting |
Applications
| DC Motor Control | Subscriber Line Interface Card (SLIC) |
|---|---|
Use Scenario: Driving 24V brushed DC fans in industrial HVAC controllers with PWM switching at 20kHz. IC Role / Device Role / Timing Role: High-side NPN switch controlling motor current path; handles 5A continuous load with minimal self-heating. Use Value: 36mΩ RSAT limits I²R loss to 0.9W at 5A, avoiding heatsink requirement on dense control boards. |
Use Scenario: Overvoltage protection and loop current regulation in analog telephone line interface circuits. IC Role / Device Role / Timing Role: High-voltage series pass element regulating tip/ring current during off-hook states. Use Value: BVCEO = 100V withstands ringing voltages up to 90V RMS while maintaining low dropout via VCE(sat) < 100mV. |
| Industrial Line Switching | High-Side Power Switch |
Use Scenario: Solid-state replacement for electromechanical relays in programmable logic controller (PLC) output modules. IC Role / Device Role / Timing Role: Main load switching transistor handling 48V DC supply with 3A resistive load. Use Value: 10A ICM rating accommodates inrush surges from solenoids and lamps without secondary crowbar protection. |
Use Scenario: Positive rail switching in battery-powered test equipment requiring reverse-polarity protection. IC Role / Device Role / Timing Role: NPN configured as emitter-follower high-side switch with base driven by level-shifted control signal. Use Value: Guaranteed hFE ≥100 at IC = 2A simplifies base resistor calculation and improves turn-on speed consistency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN high-voltage switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN25012E6TA | Higher VCEO = 120V, lower IC = 4A, SOT23-6 package | Compact size suits space-constrained designs but lacks thermal mass for sustained >3A loads | Select when board area is critical and peak current ≤4A; verify RθJA = 125°C/W does not exceed thermal budget |
| MJD122G | Same SOT223 package, VCEO = 100V, but IC = 8A and VCE(sat) = 1.2V @ 3A (higher loss) | Higher saturation voltage increases conduction loss by 18× at 3A, requiring larger heatsinking | Prefer only if legacy design compatibility is required; avoid where efficiency or thermal density matters |
Compared with ZXTN2011GTA, ZXTN25012E6TA trades current capacity for footprint reduction, while MJD122G sacrifices low-loss switching for higher current rating-neither matches the 65mV/6A combination that defines ZXTN2011GTA's thermal advantage in medium-power linear switching.

FAQ
What is the maximum continuous power dissipation for ZXTN2011GTA at 70°C ambient?
At TA = 70°C, derating from the 3.0W maximum at 25°C applies at 24mW/°C (per Note 5). The allowable power is 3.0W − (70−25) × 0.024W = 1.92W. This assumes mounting on 52mm × 52mm 2oz copper per JEDEC standards; reduced copper area lowers this value proportionally.
Is ZXTN2011GTA suitable for linear regulator applications?
No-ZXTN2011GTA is optimized for switching operation, not linear regulation. Its Safe Operating Area (SOA) curve shows limited second breakdown capability at high VCE/IC combinations, and its RθJA = 42°C/W is insufficient for sustained linear dissipation above ~1W without aggressive heatsinking.
How is the collector tab (Pin 4) electrically connected in the SOT223 package?
The collector tab is internally bonded directly to Pin 3 (collector lead); both share identical electrical potential and thermal path. It is not isolated and must be soldered to the same net as Pin 3-typically a large copper pour serving as both current path and heatsink.
Does ZXTN2011GTA require a base resistor for safe operation at 6A collector current?
Yes-base drive must be current-limited. With hFE ≥20 at IC = 6A, minimum IB = 300mA is required for saturation. A series resistor between driver and base ensures IB remains within safe limits, especially given VBE(sat) = 1.12V at 6A, which affects voltage drop and power dissipation in the resistor.
