SMBJ250CA 产品概述
一、规格简介
SMBJ250CA 是扬杰（YANGJIE）出品的一款双向瞬态电压抑制器（TVS），采用 SMB（DO-214AA）表面贴装封装，专为保护敏感电子线路免受开关瞬变、感性负载反向尖峰及雷击诱发的高能脉冲而设计。该器件在10/1000 μs波形下具有600 W峰值脉冲功率能力（占空比0.01%），适合自动贴片生产线使用。
二、关键电气参数
- 极性：双向
- 反向截止电压 Vrwm：250 V
- 击穿电压 VBR：309 V
- 钳位电压（典型）：405 V
- 峰值脉冲电流 Ipp：1.5 A
- 峰值脉冲功率 Ppp：600 W（10/1000 μs，重复率 0.01%）
- 反向漏电流 Ir：≤ 5 μA
- 工作温度范围：-55 ℃ ～ +150 ℃
三、主要特性
- 低外形 SMB 封装，适配自动贴装与回流焊工艺；
- 玻璃钝化芯片结，提供更稳定的击穿特性与可靠性；
- 双向保护结构，适用于交流/双向信号线路或两极性瞬变场景；
- 优异的钳位能力（典型钳位电压405 V），在能量冲击时能有效限制过压对后端器件的损害；
- 极低的静态漏电流（≤5 μA），在待机或低功耗设备中对电源影响小。
四、典型应用场景
- 工业控制与驱动电路中保护 MOSFET、IGBT 等功率器件；
- 通信与基站设备的信号线、接口保护；
- 消费类与计算设备的电源浪涌保护；
- 传感器单元、接口模块及其它对瞬态过压敏感的电子系统。
五、封装与装配建议
- 封装：SMB（DO-214AA），适合常规 SMT 领用和回流焊工艺；
- 布局：为降低寄生电感与实现最佳保护效果，建议将 TVS 尽量靠近被保护端口焊接，走线短且宽；
- 散热：在高能量冲击下器件会产生热量，若应用频繁承受冲击，应考虑增加 PCB 铜箔面积或散热措施；
- 焊接：遵循回流焊温度曲线，避免过高峰值温度和超时曝露以保护器件可靠性。
六、选型与注意事项
- 若保护的是单向直流线路，可考虑对应的单向型号；双向型号适用于交流或双极性脉冲保护；
- 标称 Ppp（600 W）基于10/1000 μs 单脉冲与占空比条件，实际应用中应根据冲击频率和能量作热功率和寿命评估；
- 钳位电压通常随着脉冲电流增加而上升，请按系统容许电压选择合适余量；
- 对于极低电流或高灵敏度线路，关注漏电流 Ir 对静态性能的影响。
七、储存与可靠性
- 贮存环境建议干燥、无腐蚀性气体，避免高温高湿；
- 建议在封装有效期内使用，遵循元器件供应商关于储存和回流焊的建议以保证可靠性；
- 常温下长期稳定性良好，工作温度范围宽（-55 ℃ ～ +150 ℃），适应严苛工况。
总结：SMBJ250CA 以其高能量吸收能力、紧凑表贴封装和低漏电特性，适合在各种需要高可靠瞬态保护的工业、通信及消费电子场景中作为防护元件使用。选择时请结合系统允许的钳位电压与脉冲能量评估最优型号。

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.
