BC091N-H(ES) 产品概述
一、产品简介
BC091N-H(ES) 是静芯微（ElecSuper）出品的一款表面贴装型瞬态过电压防护器件，定位于为敏感电子线路提供浪涌能量吸收和放电保护。器件具有较低的极间电容（约0.5 pF），适合对高速信号影响敏感的场合；同时具备较高的脉冲放电能力，可承受短时大电流冲击，提升系统在雷击或开关冲击下的可靠性。
二、主要特性
- 直流击穿电压（Vdc）：90 V（标称），允许范围±30%；
- 冲击击穿电压（Vimp）：600 V；
- 脉冲放电电流：2 kA（峰值）；
- 极间电容：约 0.5 pF，适合高速/高频线路；
- 封装形式：SMD，标称尺寸 4.3×3.2 mm；
- 器件尺寸（典型）：长 4.5 mm × 宽 3.2 mm × 高 2.7 mm。
三、典型电气参数（概览）
- 工作静态电压：约 90 V（±30%）——用于判断在正常工作条件下器件不自触发的电压等级；
- 脉冲放电承受能力：2 kA（单次冲击能力，具体波形与次数应参照厂方测试标准）；
- 极间电容：0.5 pF（对高速信号串扰和带宽影响极小）；
- 冲击耐受：600 V（短时冲击击穿门限）。
注：以上参数为主要参考值，设计时应以厂方最新版数据手册为准，并考虑器件公差与环境影响。
四、封装与机械特性
BC091N-H(ES) 采用 SMD 封装，标称外形 4.3×3.2 mm，器件本体典型高度 2.7 mm，长度方向常见为 4.5 mm（含工艺允许差）。小尺寸便于在受限空间内实现防护布局，适合自动贴装与回流焊工艺。
五、典型应用场景
- 通信端口与接口保护（如基站、光模块保护的输入端）；
- 电源线、车载线路、太阳能逆变器等直流系统的浪涌防护；
- 工业控制设备、仪表与测量设备中的过压防护；
- 需要兼顾高速信号完整性与抗浪涌能力的应用场合。
六、使用建议与注意事项
- 器件直流击穿电压公差较大（±30%），电路设计时应留有余量，避免在接近下限或上限工作点长期受应力；
- 对于重复浪涌、脉冲次数受限的场合，应结合系统能量吸收路径（串联阻抗、熔断器或防护器件阵列）进行整体设计；
- 极间电容小，适合高速信号线路，但仍应注意布局靠近受保护端以降低寄生电感；
- 推荐遵循厂方的回流焊与温度曲线，避免超过推荐焊接温度导致性能退化；
- 在关键应用中建议进行实际浪涌试验验证（按 IEC/ITU 等标准）以确认系统级保护效果。
七、可靠性与储运
器件适合常规电子元件储存与运输条件，避免潮湿、剧烈振动和强腐蚀性气氛。为确保焊接可靠性，若器件采用吸湿袋包装，应根据其等级进行相应回潮处理（烘烤）后贴装。
总结：BC091N-H(ES) 以其高脉冲放电能力（2 kA）、低极间电容（0.5 pF）和小尺寸封装，适用于要求高速信号兼顾浪涌保护的场合。实际选型应结合系统工作电压、冲击能量评估及厂方详细规格书进行最终确认。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
