Key Features
- 100 V collector-emitter voltage rating enabling safe switching of high-voltage loads in compact SOT-23 PNP configuration
- 3 A maximum collector current supporting medium-power switching applications from a tiny 3-pin SOT-23 footprint
- Minimum hFE of 40 ensuring predictable base drive requirements for reliable switching and linear amplification circuits
Applications
The ZXTP2029FTA PNP transistor is used in high-side switching, load switching, and current mirror circuits where 100 V breakdown and 3 A current handling are needed in a minimal PCB footprint. The SOT-23 package enables integration into space-constrained designs such as motor control pre-driver stages, relay drivers, and power management circuits in industrial and consumer electronics. Its high-voltage rating makes it suitable for flyback snubber circuits and bootstrap supply switching in offline power converters.

Frequently Asked Questions
What voltage and current ratings make ZXTP2029FTA suitable for high-side switching in industrial circuits?
The ZXTP2029FTA supports a collector-emitter voltage of 100 V and a maximum collector current of 3 A with a minimum hFE of 40, making it appropriate for high-side PNP switching of 24 V or 48 V industrial loads. These ratings allow direct drive of solenoids, relays, and LED arrays without additional protection components in typical industrial sensor and actuator interfaces.
How compact is the ZXTP2029FTA package and what PCB area does it require?
The ZXTP2029FTA uses a SOT-23 3-pin surface mount package, which measures approximately 2.9 mm x 1.6 mm, one of the smallest discrete transistor packages available. This footprint allows integration of a 100 V, 3 A PNP switching transistor into space-constrained designs such as wearable devices, portable instruments, and dense industrial control PCBs where a TO-92 through-hole part would not fit.
When is ZXTP2029FTA preferred over a lower-voltage PNP transistor for a motor pre-driver application?
For a motor pre-driver operating from a 60 V bus, the ZXTP2029FTA at 100 V provides 40 V of headroom above the bus voltage to absorb inductive kickback transients. A 60 V-rated PNP transistor would have insufficient derating for the voltage spikes generated by motor winding inductance switching at 3 A, risking transistor failure. The 100 V rating of the ZXTP2029FTA ensures reliable operation without an external transient suppression diode.
