S8550 is a PNP transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.
- Low Voltage, High Current PNP Transistor
- Continuous Collector current (IC) is 500mA
- Collector-Emitter voltage (VCEO) is -25 V
- Collector-Base voltage (VCB0) is -40V
- Emitter Base Voltage (VBE0) is -5V
- Current Gain (hFE), 85 to 300
- Commonly used as Class B Push-pull transistors
