Product Summary

The 2SA1742 is a power transistor developed for high-speed switching and features a high hFE at low VCE(sat). This transistor is ideal for use as a driver in DC/DC converters and actuators. In addition, a small resin-molded insulation type package contributes to high-density mounting and reduction of mounting cost.

Parametrics

2SA1742 absolute maximum ratings: (1)Collector to base voltage VCBO: -100 V; (2)Collector to emitter voltage VCEO: -60 V; (3)Emitter to base voltage VEBO: -7.0 V; (4)Collector current (DC) IC(DC): -7.0 A; (5)Collector current (pulse) IC(pulse): -14 A; (6)Base current (DC) IB(DC): -3.5 A; (7)Junction temperature Tj: 150 °C; (8)Storage temperature Tstg: -55 to +150 °C.

Features

2SA1742 features: (1)High hFE and low VCE(sat): hFE ≥ 100 MIN. @VCE = -2.0 V, IC = -1.5 A; (2)VCE(sat) ≥ -0.3 V MAX. @IC = -4.0 V, IB = -0.2 A; (3)Full-mold package that does not require an insulating board or bushing.
