Vishay General Semiconductor SE40CLJ Surface-Mount High Voltage Rectifiers
Vishay General Semiconductor SE40CLJ Surface-Mount High Voltage Rectifiers are designed for demanding power conversion applications that require high current handling, efficient thermal performance, and reliable operation. The Vishay SE40CLJ rectifiers feature a maximum average forward current of 40A and a repetitive peak reverse voltage rating of 600V, suitable for high‑power rectification tasks. Engineered with an oxide planar chip junction and housed in the eCool SMPD package, the SE40CLJ supports top‑side cooling and offers a creepage distance of at least 4.3mm, enhancing safety in high‑voltage environments.
The Vishay SE40CLJ rectifiers deliver low forward voltage drop (typically 0.98V at 40A and +25°C) and maintain low leakage currents, with only 5µA at rated reverse voltage under standard test conditions. These devices also provide fast recovery performance with a typical reverse recovery time of 0.28µs, enabling efficient switching in high-frequency circuits. Robust thermal characteristics include a junction‑to‑case thermal resistance of 0.7°C/W and an operating junction temperature range from -55°C to +175°C, supporting reliable use in harsh environments. Typical applications include onboard chargers (OBCs), charging stations, and bridge rectifier functions in power electronics systems.
