The BY239L-800 from STMicroelectronics is a standard rectifier diode designed for applications requiring high surge current capability and a low forward voltage drop. This component features a repetitive peak reverse voltage of 800V and a non-repetitive forward surge current of 140A for a 10ms sinusoidal pulse.
With an average forward current rating of 10A at 100°C case temperature and a power dissipation of 12.5W at 100°C case temperature, the BY239L-800 is suitable for various power applications. The junction to case thermal resistance is 2°C/W, aiding in thermal management.
The diode operates within a storage and junction temperature range of -40°C to +125°C. It is housed in a TO220AC plastic package, which is a common through-hole mounting type. The maximum forward voltage drop at 30A and 25°C junction temperature is 1.45V, and the reverse current at 125°C junction temperature is a maximum of 500μA.
This rectifier diode is designed for general-purpose rectification where high surge handling is beneficial. Its specifications make it a reliable choice for power supply circuits and other applications demanding robust performance under transient conditions.
