BU2527AX NPN Power Transistor 1500V 12A 45W
The BU2527AX is a high-voltage, high-speed switching NPN power transistor encapsulated in a TO-3P(H)IS plastic package. This silicon diffused power transistor is specifically designed for demanding applications, particularly in the horizontal deflection circuits of high-resolution CRT monitors. Its robust design and improved RBSOA (Reverse Bias Safe Operating Area) performance make it a reliable choice for operations up to 64 kHz.
Features
- High Collector-Emitter Sustaining Voltage: With a VCEO(SUS) of 800V minimum, it can handle high voltage requirements.
- High Switching Speed: Optimized for fast switching, crucial for horizontal deflection circuits.
- High Reliability: Offers minimal variation between batches, ensuring consistent and dependable performance.
- Fully Isolated Package: The TO-3P(H)IS package provides electrical isolation.
