What are the key features of BUV28?
- 10 A collector current and 200 V collector-emitter breakdown voltage in a compact TO-220AB plastic package for high-power switching and amplification
- Single NPN BJT configuration (JEDEC TO-220AB) with rectangular body and 3-pin vertical lead form enabling direct PCB mounting with heatsink attachment
- STMicroelectronics BUV28 complies with JESD-609 e3 halogen-free soldering requirements, supporting modern RoHS-compatible manufacturing processes
What is BUV28 used for?
The BUV28 is used in switched-mode power supply drivers, motor speed controllers, and high-voltage linear regulators where an NPN transistor must handle 10 A continuous collector current from a 200 V rail. Its TO-220AB package allows direct mounting to a heatsink, making it practical for audio power amplifier output stages and solenoid or relay driver circuits requiring sustained high-current switching.

Frequently Asked Questions
What are the maximum collector current and collector-emitter voltage ratings of the STMicroelectronics BUV28?
The BUV28 is rated for a maximum collector current (IC) of 10 A and a maximum collector-emitter voltage (VCEO) of 200 V. These ratings make it suitable for high-power NPN switching circuits such as SMPS drivers, motor controllers, and solenoid drivers operating from mains-derived or industrial DC bus voltages up to 200 V.
How does the TO-220AB package of the BUV28 facilitate heatsink mounting in high-power circuit designs?
The TO-220AB package features a metal tab on the 3-pin plastic body that can be bolted directly to an external heatsink using a standard TO-220 mounting clip or screw. At 10 A and 200 V, thermal dissipation management is critical; the tab's direct thermal path to a heatsink allows the BUV28 to operate continuously at high collector currents without exceeding junction temperature limits.
When is the BUV28 a better choice than a MOSFET for a 200 V, 10 A switching application?
The BUV28 NPN BJT is preferred over a MOSFET in applications where gate drive circuitry is costly or unavailable, such as simple base-drive linear regulators or legacy industrial controllers operating from 200 V rails. BJTs like the BUV28 also exhibit more predictable saturation behavior at 10 A in low-frequency switching below 100 kHz, where MOSFET switching speed advantages are less relevant and base-drive simplicity reduces design cost.
