P3100SB 放电管（SMB / DO-214AA）产品概述
一、功能与定位
P3100SB 是由 Brightking（台湾君耀）推出的 SMB 封装过压/浪涌保护放电管，适用于对中低电压电源线和信号线进行浪涌能量吸收与钳位保护。器件在正常工作时保持高阻态，在遭受瞬态过压时迅速导通，耗散能量并保护后端电路。
二、主要电气参数
- 断态峰值电压 Vdrm：275 V（器件在断态时可承受的最大峰值电压）
- 开关电压 Vs：350 V（触发导通的电压门限）
- 峰值脉冲电流 Ipp：80 A（典型浪涌冲击时的脉冲承受能力）
- 漏电流：5 μA（断态漏流，体现静态功耗与绝缘性能）
- 保持电流 Ih：150 mA（导通后维持导通所需的最小电流）
- 通态电压 Vt：4 V（器件在导通时的电压降，影响被保护电路的电压应力）
- 通态电流 It：2.2 A（连续或额定通态电流能力）
- 断态电容 Co：45 pF（对高频信号的影响，决定对信号完整性的影响程度）
- 工作温度范围：-40 ℃ ~ +85 ℃
三、封装与机械特性
SMB（DO-214AA）表面贴装封装，适合自动贴装与回流焊工艺，占板面积小、散热路径合理。封装兼具机械强度与安装便捷性，适用于商用及工业环境。
四、典型应用场景
- 直流/交流电源输入防护（小型开关电源、适配器）
- 信号线与数据总线的浪涌防护（通信、仪表）
- 家电与工业设备的雷击与开关冲击抑制
- 需要低断态电容以维持信号完整性的场合
五、选型与使用建议
- 若系统最大工作电压接近或超过 275 V，应优先核对断态安全裕度；触发电压 350 V 说明在更高瞬态下才会导通。
- 关注断态电容 45 pF 对高速信号的影响，必要时在布局上采用屏蔽或远离敏感路径。
- 保持电流 Ih 与通态电压 Vt 关系决定钳位后的热耗，确保散热设计与连续电流需求匹配。
- 推荐按厂商资料进行 PCB 阔脚与焊盘布局，遵循回流焊温度与潮湿防护规范。
六、可靠性与注意事项
器件额定工作温度为 -40 ℃ 至 +85 ℃，在高温或频繁大电流浪涌下需考虑热循环寿命与老化。储存与贴装过程中避免静电与机械冲击。出于安全考虑，建议在系统级进行冗余或组合保护（如配合陶瓷电容、PTC 或 TVS 二极管）以提升整体防护能力。
P3100SB 以其紧凑 SMB 封装与 80 A 的脉冲承受能力，适合对空间与成本敏感但需可靠浪涌保护的应用场景。若需更详细的电气曲线及封装尺寸，请参考 Brightking 官方数据手册。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
