Product details

800 V, 3.5 A single-phase bridge in a through-hole package

The BU2008-E3/45: The Vishay BU2008-/45 is a single-phase bridge rectifier rated for 800 V peak reverse voltage and 3.5 A average rectified output current — the two numbers that define its place in a power supply front end or DC bus precharge circuit.

Thermal and package fit for the BOM

Supplied in tube packaging, which is the typical format for through-hole power devices going into manual or wave-solder assembly lines.

Active lifecycle and compliance status

ROHS3 compliant, which covers the full ten restricted substances including the four phthalates — no exemption paperwork needed for EU-market equipment.

Frequently asked questions

How can I order the BU2008-/45 or check availability?

The BU2008-/45 is an active Vishay part sourced through independent distribution.

What is the reverse leakage current of the BU2008-/45 at its rated voltage?

Maximum reverse leakage is 5 µA at 800 V reverse voltage, which is typical for a standard-recovery bridge of this current class and keeps standby losses negligible in a continuously-powered circuit.
