2SC945 NPN TO-92 Bipolar Transistors – BJT
2SC945 NPN TO-92 Bipolar Transistors – BJT is a classic silicon NPN bipolar junction transistor provided in a compact TO-92 through-hole package and engineered to serve as a reliable active element in low-power electronic circuits. This transistor has long been used in both analog and switching applications where a moderate voltage capability and good linearity are required. The device exhibits a collector-emitter breakdown voltage (VCEO) of approximately 50 V, making it suitable for low to moderate voltage operations, and can handle a continuous collector current of up to about 150 mA, which accommodates many small-signal amplifier stages and light switching tasks.
Features:
- High DC current gain (hFE) linearity with classifications from 90 to 600.
- Low noise figure for clean audio amplification.
- High transition frequency (fT) up to 190MHz typical.
- Low collector-emitter saturation voltage for efficient switching.
Pinout Configuration:
| Pin Number | Pin Name | Description |
| 1 | Emitter | Current Drains out through emitter, normally connected to ground |
| 2 | Collector | Current flows in through collector, normally connected to load |
| 3 | Base | Controls the biasing of transistor, Used to turn ON or OFF the transistor |
Applications:
- Low current switches
- Pre-amplifiers
- H-bridge circuits for low power motors
- Audio frequency amplifier circuits
- Oscillator circuits
Package Include:
1x 2SC945 NPN TO-92 Bipolar Transistors – BJT
