BUW13A NPN Transistor 450V 15A 175W TO-3PN
The BUW13A NPN Power Transistor is a glass‑passivated, high‑speed switching device housed in a TO‑3PN metal‑flanged package designed for rugged thermal performance. BUW13A offers VCEO = 450 V, IC = 15 A, peak ICM = 30 A, and maximum power handling of 175 W at TC=25 °C. The collector is bonded directly to the metal baseplate, and pin-out follows: pin 1=Base, pin 2=Collector, pin 3=Emitter. It’s suitable for converters, inverters, motor drivers, and high-speed switching circuits.
Features
- High‑voltage NPN transistor rated for 450 V collector‑emitter and 1000 V collector‑base.
- 15 A continuous collector current; up to 30 A peak for short pulses.
- 175 W maximum dissipation (at TC=25 °C); low thermal resistance of ~0.7 °C/W.
- Glass‑passivated die for enhanced reliability in high-speed power switching.
- TO‑3PN metal-flanged package with collector tied to the case; Base=pin 1, Collector=pin 2, Emitter=pin 3.
