MPSA12 NPN Darlington Transistor
The MPSA12 NPN Darlington Transistor is a silicon planar NPN bipolar transistor arranged in a Darlington configuration to deliver exceptionally high current gain for switching and amplification tasks in electronic designs. This transistor is engineered to provide robust performance in circuits where a high input impedance and substantial current amplification are essential. Its Darlington pair architecture internally combines two transistors, achieving a typical DC current gain (hFE) of up to 20,000 at IC = 10 mA, VCE = 5 V, making it suited for applications requiring significant gain with minimal base drive.
Features:
- Darlington configuration for amplified current handling in a single package.
- Low leakage currents ensuring efficient off-state operation.
- Compact TO-92 package for easy through-hole integration.
- Wide operating temperature range for environmental resilience.
