MMBTA92 BJT Description
The MMBTA92 is a high voltage small signalPNP transistor, designed for telephone signal switching and for high voltage amplifiers. It has a wide operating temperature ranging from -65°C to 150°C. The MMBTA92 has a bit lower gain, so assuming hfe=25, 17mA * 25 = 425mA which should fully saturate T2 right up close to its maximum Ic of 500mA.
