It delivers 4 A average rectified current (Io) with a 400 V peak reverse voltage (Vrrm) — the headline ratings that govern the bulk rectification stage in a power supply. The forward voltage drop is specified at 1 V max at 4 A (If), and reverse leakage is 5 µA at the rated 400 V. These define the conduction loss and the off-state power budget in the application. ## Temperature grade and operating envelope The junction temperature range spans -50°C to 150°C (TJ). This covers the full industrial temperature band with margin — the rectifier can sit in a sealed enclosure near a hot transformer or in an outdoor telecom power supply without derating the junction.","metaTitle":"onsemi GBU4G Bridge Rectifier, 400V 4A, GBU Package","metaDescription":"onsemi GBU4G single-phase bridge rectifier, 400V peak reverse, 4A average rectified current.
