The ESM3045DV is an NPN Darlington power transistor module manufactured by STMicroelectronics. It features a collector-emitter sustaining voltage of 450V and a continuous collector current rating of 24A, with a peak current capability of 36A. The device integrates an ultrafast freewheeling diode and is designed for high-current switching applications.
Key electrical characteristics include a minimum DC current gain (hFE) of 120 at 20A and 5V, low collector-emitter saturation voltage (typically 1.4V at 20A, 1.2A base current), and fast switching performance with a typical fall time of 0.15µs. The module dissipates up to 125W at a case temperature of 25°C, with a thermal resistance junction-to-case of 1°C/W for the transistor and 2°C/W for the diode.
The device is housed in an ISOTOP package designed for chassis mounting, providing full insulation with an isolation voltage of 2500V RMS from terminals to heatsink. It is suitable for industrial applications such as motor control, switch-mode power supplies, UPS systems, DC/DC and DC/AC converters, and welding equipment.
