Vishay Bridge Rectifier 600 V 300 A 4-Pin Single Through Hole KBU8J-E4/51

Vishay KBU8J-E4/51 Bridge Rectifier is a heavy-duty, single-phase Bridge Rectifier designed for converting AC input into DC output with high reliability and thermal performance. Operating at a peak reverse repetitive voltage of 600 V and capable of handling surge currents up to 300 A, this 4-pin, through-hole component is ideal for industrial, laboratory, construction, and manufacturing power supply applications.

This rectifier supports a forward current of 8 A and maintains a low peak forward voltage drop of 1 V, enhancing energy efficiency. Its operating temperature range from -50°C to 150°C ensures durability in harsh operating environments. The KBU package includes soldering pins suitable for through-hole mounting on PCBs, providing robust mechanical and electrical connections.

Compactly sized at 23.7 mm length, 19.3 mm height, and 7.1 mm width, the device fits neatly into circuit designs demanding space-saving solutions. The isolating voltage of 1500 Vrms adds an essential layer of safety by isolating the device electrically from the PCB or heat sink. Although it holds no specific automotive or additional standards approvals, it meets UL E54214 listing for reliability assurance.

Typical applications include full-wave rectification in power converters, power supplies, industrial electronic devices, and HVAC control units. Vishay’s KBU series is recognized for its consistent performance in converting AC to DC currents efficiently while withstanding high surge conditions.
