Title: Darlington transistor
Inventor: OGAWA SHOGO
IPC: H01L21/331
Filed: 1989-11-06
Abstract: PURPOSE:To prevent a drive circuit from being broken due to the erroneous operation and erroneous turn-ON of the circuit by a method wherein the time of reverse recovery of a speed-up diode connected between the base and the emitter of the first-stage transistor is made longer. CONSTITUTION:A Darlington Tr with a reversed speed-up diode SUD 3 connected between a base and an emitter of a preceding-stage transistor Tr1 is brought into a reverse-biased state at the time of turn-OFF. At this time, a current flows from an emitter terminal 12 to a base terminal 11. When a base current is turned-ON, the SUD 3 is brought into a state of reverse recovery, the base current does not flow in the Tr1 until carriers in the SUD 3 are annihilated and a collector current from a terminal 13 to the terminal 12 does not flow. Accordingly, the longer the time of reverse recovery of the SUD 3 is made, the longer a turn-ON delay time becomes. Thereby, the erroneous operation and erroneous turn-ON of a drive circuit can be prevented from generating.
