The maximum amount of current that could flow through the Collector pin is 200mA, hence we cannot connect loads that consume more than 200mA using this transistor.
This is where a PNP transistor differs from a NPN transistor, a Logic state (blue colour) is used to toggle between Ground and Signal Voltage (Emitter-Base Voltage VBE) as shown belowĢN3906 has a gain value of 110 to 300, this value determines the amplification capacity of the transistor. Note: Complete Technical Details can be found at the 2N3906 datasheet given at the end of this page.īC157, BC558, 2SA1943, BD140, S8550, TIP127, TIP42ĢN3906 is a PNP transistor hence the collector and emitter will be closed (Forward biased) when the base pin is held at ground and will be opened (Reverse biased) when a signal is provided to base pin. Continuous Collector current (IC) is 200mA.
