IMZ1AS-AU_S1_000A1

Overview

The IMZ1AS-AU_S1_000A1 is a complementary dual general-purpose transistor manufactured by Panjit International Inc. It integrates a PNP transistor (Tr1) and an NPN transistor (Tr2) within a single SOT-23 6L package. The device features a collector-emitter voltage rating of 50V for the PNP section and -50V for the NPN section, with a maximum DC collector current of 150mA. Key electrical parameters include a typical DC current gain (hFE) ranging from 120 to 560 at 1mA collector current. The transition frequency is specified at 140MHz for the PNP and 180MHz for the NPN. Total power dissipation is rated at 300mW, and the operating junction temperature range extends from -55°C to +150°C.
