Product Description
Vishay PB4008-E3/45 bridge rectifier is engineered for converting alternating current (AC) input into direct current (DC) output with high efficiency and reliability. It features a 4-pin single configuration and is part of the PB series, incorporating Vishay's advanced isoCink+™ SIL PCB mounting technology, which offers enhanced thermal conductivity for superior performance in demanding applications.
This bridge rectifier supports a peak reverse repetitive voltage (VRRM) of 800 V and a forward current (IF) rating of 40 A continuous, with surge current capability (IFSM) up to 400 A, making it ideal for linear and switching power supplies commonly used in home electrical appliances and white goods products.
The device's thermal and electrical specifications include a maximum operating temperature of 150°C and minimum operating temperature of -55°C, ensuring robust operation across a wide temperature range. The forward voltage drop is low at 1.1 V, and the peak reverse current is minimal at 500 μA, yielding efficient power conversion with minimal losses.
Construction uses a through-hole mount type enabling secure PCB attachment, and its compact package dimensions of 30.3 mm length, 5.1 mm width, and 20.3 mm height aid integration into compact designs. The rectifier is tested to UL standard UL 1557 for electrical isolation within semiconductor devices, endorsing its safety and reliability.
These features make the Vishay PB4008-E3/45 suitable for use in industrial, commercial, and residential power supply applications requiring dependable AC to DC conversion in a space-saving form factor.
Enhanced isoCink+™ SIL PCB Mounting Package with high current density and thermal conductivity. UL 1557 standard tested for electrical isolation safety. Peak reverse voltage of 800 V with forward continuous current rating of 40 A.
