1) Built-in zener diode between collector and base. 2) Zener diode has low voltage dispersion. 3) Strong protection against reverse power surges due to “L”
loads. 4) Darlington connection for high DC current gain. 5) Built-in resistor between base and emitter. 6) Built-in damper diode. zEquivalent circuit
