600 V peak reverse — why this rating matters for your line rectifier stage
The PB3006-E3/45: The PB3006-/45: The PB3006-/45 is a Vishay single-phase bridge rectifier in the isoCink+ series, rated for 600 V peak reverse voltage and 30 A average rectified current. That 600 V rating covers the peak of a 240 VAC line (which peaks at ~340 V) with healthy margin, and it also handles a 400 VDC bus without avalanche breakdown. The 30 A continuous rating means this bridge can supply a 30 A DC load at rated temperature — useful for bulk power supplies, battery chargers, and motor-drive front ends where you need a single package to handle the full-wave rectification.
Forward voltage and junction temperature — the thermal budget drivers
Forward voltage is specified at 1.1 V typical at 15 A — that's the conduction loss floor at half the rated current.
Through-hole 4-SIP isoCink+ package — mounting and thermal path
The through-hole package (isoCINK+ PB) is a standard four-pin single-in-line footprint. The isoCink+ construction uses a copper leadframe with a molded isolation barrier that provides creepage and clearance for the 600 V rating.
