Description
A1742 transistor is -60V, -7A, PNP Silicon Power Transistor.
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.
🧩 Features
- High hFE and low VCE(sat)
- hFE ≥ 100 @ VCE = −2.0 V, IC = −1.5 A
- VCE(sat) ≤ −0.3 V @ IC = −4.0 A, IB = −0.2 A
- Full-mold insulated package (no insulating washer or bushing required)
