ULBF810 是晶导微电子推出的一款单相整流桥,专为高压、高电流整流应用设计。器件具有高耐压(Vr = 1000V)、低正向压降(Vf = 1.0V @ 4A)、高浪涌承受能力(Ifsm = 350A)和极低的反向漏电流(Ir = 5µA @ 1000V),典型整流电流为 8A。器件工作结温范围宽 (-55℃ ~ +150℃),适应恶劣环境与工业级应用需求,封装为 ULBF,便于系统集成与散热管理。
ULBF 封装设计兼顾尺寸与散热,实际散热性能受 PCB 走线和散热片设计影响较大。使用建议:
晶导微电子对 ULBF810 进行出厂电参数测试,典型合格项包括正向电压、反向漏电、浪涌承受及耐压测试。建议用户在批量使用前进行来料检验,重点关注:耐压、漏电和正向压降一致性,以及外观与封装引脚完整性。
ULBF810 适合需要 1kV 等级耐压与中等电流(8A)整流的场合。若系统需更低正向压降或更高连续电流,可考虑低 Vf 的肖特基整流器或更大电流等级的桥式整流器;若需更低反向恢复造成的开关损耗,应考察快速恢复或超快恢复二极管的参数并与设计频率匹配。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
