BJ091M-1 产品概述
一、概述
BJ091M-1 是面向电源端口的高能脉冲浪涌保护器，采用小尺寸 SMD 封装，专为在有限空间内提供高效浪涌抑制设计。器件为双极（2 极）结构，能够承受高达 10kA（8/20µs）的脉冲放电电流，同时保持极低的极间电容和插入损耗，适合对信号完整性和高速电源链路要求较高的应用场景。
二、主要性能参数
- 极数：2
- 脉冲放电电流（8/20µs）：10,000 A
- 直流击穿电压 Vdc：108 V
- 冲击击穿电压 Vimp：600 V
- 极间电容：0.5 pF（容差 ±20%）
- 工作温度范围：-40 ℃ ~ +125 ℃
- 湿度敏感度等级（MSL）：1 级
- 尺寸（典型）：5.4 × 5.4 × 5.0 mm；封装标注 SMD, 5 × 5.4 mm
三、产品特性
- 小尺寸设计，便于在紧凑型电源模块或接口板上布局。
- 高能量吸收能力（10kA/8/20µs），针对雷击或开关瞬态场景有效保护下游器件。
- 低极间电容（约 0.5 pF），对高频信号和电源噪声影响极小，保持良好信号完整性。
- 响应迅速、寿命长、插入损耗低，适合长期在线保护。
- MSL1，出厂后在常温常湿下可直接贴装，无需特殊烘烤处理。
四、典型应用
- 各类电源输入端口（DC jack、电源母座）浪涌保护
- 充电器、适配器、电源模块的前端保护
- 工业与通信设备的电源接口及总线保护
- 对电源线对地或线间浪涌事件需快速抑制的场合
五、使用与布局建议
- 尽量将 BJ091M-1 紧贴被保护的电源接口布置，减少引线和走线长度以降低寄生电感。
- 若作为线对线保护，置于 V+ 与 V- 间；如果需要接地保护，配合低阻抗接地回路以提高吸能效率。
- 推荐在外部进行一次性浪涌试验（8/20µs）验证系统级承受能力与旁路路径完整性。
- 采用推荐的 PCB 焊盘、充足焊盘面积与合理锡量，保证良好焊接及热稳定性（MSL1 可直接回流）。
- 高温回流时遵循常规贴片回流曲线，避免超出器件工作温度极限。
六、可靠性与维护
BJ091M-1 设计用于多次承受标准 8/20µs 浪涌脉冲，具备快速响应和长使用寿命。由于其 MSL 等级为 1，正常储存与生产环境下不需特殊干燥处理。长期工作时建议定期在系统级进行功能与绝缘检测，确认器件在遭受大能量冲击后仍保持保护能力，必要时更换受损器件以维持系统可靠性。
七、封装与订购信息
- 品牌：Bencent（槟城）
- 封装形式：SMD，5 × 5.4 mm（器件尺寸参见款式规格）
- 采购与样片建议：在样机阶段建议与其它保护器件（如熔断、滤波器件）配合做系统级浪涌试验，确认动作点与能耗匹配。
总结：BJ091M-1 以其紧凑尺寸、10kA 的强大浪涌承受能力和极低电容，适合对电源端口进行高可靠、低干扰的浪涌保护。在布线与焊接上遵循短路径、低阻抗回路的设计原则，可获得最佳保护效果。

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.
