Key Features
- 100 V collector-emitter breakdown voltage and 5 A maximum collector current in a compact 4-pin TO-261AA (SOT-223) SMT package
- Minimum DC current gain (hFE) of 15 supporting efficient base-drive circuits for high-current load switching up to 5 A
- Collector tab connected to the exposed thermal pad for improved heat dissipation, enabling higher continuous current in PCB-mounted applications
Applications
The ZX5T953GTA is suited for high-current DC motor control, solenoid drivers, and LED array switching circuits requiring up to 5 A collector current at supply rails up to 100 V. Its 4-pin SOT-223 package with collector thermal pad enables effective thermal management on standard FR4 PCBs, reducing the need for external heat sinks in moderate power applications. The device is commonly used in industrial automation, power tool controllers, and automotive accessory drivers where compact SMT NPN transistors with 100 V ratings are required.

Frequently Asked Questions
What are the key voltage and current ratings of the ZX5T953GTA NPN transistor?
The ZX5T953GTA is rated for a maximum collector-emitter voltage (VCEO) of 100 V and a maximum collector current (IC) of 5 A. The minimum DC current gain (hFE) is 15, and the device is packaged in a 4-pin TO-261AA (SOT-223) SMT case suitable for switching loads up to 100 V in industrial and automotive applications.
How does the collector tab configuration in the ZX5T953GTA improve thermal performance on a PCB?
The ZX5T953GTA uses a 4-pin TO-261AA package where the collector is internally connected to the large exposed thermal pad on the underside. This allows direct heat conduction to the PCB copper plane, reducing junction-to-board thermal resistance and enabling sustained collector currents approaching 5 A without requiring an external heat sink in most standard FR4 PCB layouts.
Which high-current switching applications best match the ZX5T953GTA specifications?
DC motor driver stages, relay coil drivers, and 12 V to 48 V solenoid actuators are the best matches for the ZX5T953GTA. Its 5 A collector current and 100 V VCEO rating comfortably handle inductive load switching with appropriate flyback diodes, while the SOT-223 footprint saves PCB space compared to TO-220 through-hole transistors handling similar 5 A load currents.
Is the ZX5T953GTA RoHS compliant and what is the expected procurement lead time?
The ZX5T953GTA has a Pb-free code of No, indicating it uses a non-lead-free (standard tin-lead) finish, which may limit its use in RoHS-restricted designs. The standard factory lead time is 12 weeks from Diodes Inc. for production orders, so designers requiring immediate stock of this 5 A, 100 V NPN transistor should verify distributor inventory availability before design commitment.
