BDFN2C2R51V 是 BORN(伯恩半导体)推出的一款双向瞬态电压抑制器(TVS),以超小体积封装实现对低电压敏感线缆和信号接口的有效浪涌与静电放电保护。器件采用 DFN1006 小封装,适合对空间和高度有限的移动设备、通信终端与精密电子模块的保护需求。
该器件 Vrwm 为 2.5 V,表示在正常工作条件下对 2.5 V 及以下信号线不导通;当出现高能瞬态时,器件在约 3.6 V 附近进入击穿并将电压钳位在约 8 V,借助最大 8 A 的 8/20 µs 脉冲承受能力快速吸收能量。200 nA 的低漏电和 20 pF 的低结电容使其在保护敏感高速信号(如某些低压接口与控制线)时既不会带来明显负载,也不会显著影响信号完整性。
器件采用 DFN1006 小型封装,便于在密集 PCB 布局中靠近被保护引脚贴装。建议布局要点:
BDFN2C2R51V 针对 IEC 61000-4-2/4-4/4-5 的抗扰性能设计,通过相应试验可为产品提供 ESD、脉冲群和雷击/开关瞬态的保护能力。其低漏电和小封装特性也利于长期稳定工作于移动与低功耗系统中。
总结:BDFN2C2R51V 是一款面向 2.5 V 级低电压、高速信号保护场景的双向 TVS 器件,凭借 8 A/60 W 的瞬态吸收能力、低漏电与 20 pF 的低结电容,在体积受限且要求高抗扰性的应用中具有良好的性价比和实用性。

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.
