Description
SS8050D331 is 25V, 1.5A, NPN Transistor. This is a general-purpose NPN bipolar junction transistor (BJT) designed for medium-current amplification and switching applications. With a relatively high collector current capability for a TO-92 package, it is widely used in driver stages, low-power switching, and signal amplification circuits.
Features
- NPN silicon transistor
- High collector current capability (up to 1.5A)
- Low saturation voltage (VCE(sat))
- Good DC current gain (hFE) characteristics
- Compact TO-92 package
- Suitable for switching and amplification
Absolute maximum ratings ( Ta=25°C )
1. Collector to Base Voltage: Vcbo = 40 V
2. Collector to Emitter Voltage: Vceo = 25 V
3. Emitter to Base Voltage: Vebo = 5 V
4. Collector Current: Ic = 1500 mA
5. Collector Dissipation : Pc = 1 W
6. Junction Temperature: Tj = 150°C
