The GBPC2508/1 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor. It utilizes silicon technology and features a flange mount package designated as S-PUFM-D4. The device provides a maximum average forward output current of 25 A and a peak repetitive reverse voltage (Vrrm) of 800 V. Key electrical parameters include a maximum non-repetitive peak forward surge current of 420 A, a peak forward voltage of 1.1 V, and an operating junction temperature range from -55°C to +150°C.
This component is officially listed as obsolete and is no longer manufactured by the producer. Procurement must focus on verifying availability through secondary market channels or authorized distributors holding remaining stock. Designers should confirm the authenticity of existing inventory and assess long-term supply chain risks associated with discontinued parts before finalizing integration plans.
Engineers requiring this specific part number must account for its discontinued status when planning production runs. Alternative selection should prioritize components within the same VS-GBPC series that offer identical electrical ratings and mechanical dimensions. Verification of lead times and lot traceability is critical when sourcing obsolete discrete semiconductors for replacement projects.
The GBPC2508/1 belongs to the broader family of general-purpose bridge rectifiers designed for industrial and commercial power conversion. It shares functional similarities with active variants like the GBPC2508 and VS-GBPC2508W, which maintain similar 25A and 800V specifications. This specific suffix indicates a legacy configuration within Vishay's discrete semiconductor portfolio.
Public confirmed substitute part numbers include GBPC2508 and VS-GBPC2508W. These alternatives provide matching 25A current and 800V voltage ratings. Engineers must verify mechanical compatibility and pinout alignment during cross-reference implementation.
