The ESM4045DV is an NPN Darlington transistor from STMicroelectronics designed for high-power switching applications. It features a collector-emitter voltage (Vceo) of 450V and a continuous collector current (Ic) of 42A, with a power dissipation of 150W. The device offers a minimum DC current gain (hFE) of 220 at 35A collector current and 5V Vce, and a low saturation voltage of 1.4V maximum at 2A base current and 35A collector current. This Darlington configuration provides high current gain, making it suitable for applications requiring high current handling with moderate drive current. The transistor is housed in an ISOTOP package, designed for chassis mounting, which provides excellent thermal performance and mechanical robustness. The operating junction temperature is rated up to 150°C. Typical applications include motor control, power inverters, and industrial switching power supplies.
