What are the key features of PBSS4140V?
- Low saturation voltage (VCEsat) NPN design with 1 A collector current and 40 V VCEO enables high-efficiency load switching in battery-powered portable applications
- Minimum DC current gain (hFE) of 200 allows reliable drive from low-current microcontroller I/O pins without additional drive stage circuitry
- Ultra-compact 6-pin SOT666 SSMini package with flat lead construction supports high-density SMT assembly in space-constrained consumer and wearable electronics
What is PBSS4140V used for?
The PBSS4140V is designed for load switching, relay driving, and signal amplification in portable consumer electronics, wearables, and battery-managed IoT devices where a low-saturation NPN transistor rated at 1 A and 40 V is required in a minimal PCB footprint. Its high current gain of 200 minimum allows direct drive from 3.3 V microcontroller outputs in motor control pre-driver stages and LED driver circuits. The SOT666 SSMini package's low thermal resistance supports continuous 1 A operation with appropriate PCB copper pour for heat spreading.

Frequently Asked Questions
What are the maximum collector-emitter voltage and collector current ratings of the PBSS4140V?
The PBSS4140V is rated for 40 V maximum collector-emitter voltage (VCEO) and 1 A maximum continuous collector current (IC). Its minimum DC current gain (hFE) of 200 ensures sufficient base-to-collector amplification for microcontroller-driven switching at base currents as low as 5 mA to achieve full 1 A collector saturation in load switching circuits.
How does the low-saturation characteristic of the PBSS4140V benefit battery-powered portable designs?
The PBSS4140V's low VCEsat means less voltage is dropped across the transistor when conducting 1 A at 40 V, reducing power dissipation and extending battery runtime in portable electronics. For example, a VCEsat of under 200 mV at 100 mA base current translates to less than 200 mW conduction loss at full 1 A load, compared to standard bipolar transistors with VCEsat above 400 mV under similar conditions.
What packaging advantage does the SOT666 SSMini format provide compared to a standard SOT-23 for compact PCB designs?
The 6-pin SOT666 SSMini package of the PBSS4140V has a smaller body footprint than a conventional SOT-23-3, allowing placement in areas under 2 mm x 2 mm on the PCB while providing 6 contacts for dual-signal or complementary configurations. This is particularly valuable in wearable devices and hearing aid PCBs where multiple switching transistors must fit within tight layout constraints near sensitive analog sections.
