MPSA44 NPN High Voltage Bipolar Transistor

From the shop's description

MPSA44 NPN High Voltage Bipolar Transistor The MPSA44 NPN High Voltage Bipolar Transistor is a silicon bipolar junction transistor engineered for robust high‑voltage switching and amplification in a wide range of electronic designs. It is specifically designed to handle elevated voltage conditions in circuits where reliable performance under stress is critical. The device is optimized for applications requiring a high collector‑base voltage and substantial breakdown margins while maintaining low leakage and predictable gain characteristics. Feature: High collector-emitter breakdown voltage of 400VDC. Supports continuous collector current up to 300mADC. Low collector-emitter saturation voltage for improved efficiency. Rugged TO-92 plastic package for reliable through-hole mounting. Wide operating temperature range from -55°C to +150°C. High-speed switching and linear amplification capabilities. Low output capacitance for better high-frequency performance.
