SMBJ10CA 产品概述
一、产品简介
SMBJ10CA 是 DOWO（东沃）出品的一款玻璃钝化芯片 TVS（瞬态电压抑制器）二极管，双向结构，针对瞬态浪涌和电气过压保护设计。器件符合 RoHS 要求，封装为 SMB（DO-214AA），适合对抗雷击、开关瞬态、负载倾卸等脉冲干扰的应用场景。
二、主要电气参数
- 极性：双向
- 反向截止电压 Vrwm：10 V
- 击穿电压 VBR：11.1 V
- 钳位电压（典型）：17 V
- 峰值脉冲电流 Ipp：35.29 A
- 峰值脉冲功率 Ppp：600 W（10/1000 μs 波形，重复率/占空比 0.01%）
- 反向漏电流 Ir：5 μA
- 工作温度范围：-55 ℃ ~ +150 ℃
三、关键特性与优势
- 玻璃钝化芯片，提供优良的可靠性与稳定性；
- 对 10/1000 μs 工况有 600 W 峰值脉冲承受能力，适合工业与汽车级冲击；
- 低漏电流，减少待机损耗；
- 极快响应时间，能在瞬间钳位电压，保护下游器件；
- 双向结构对交流或正负极性脉冲均有效，省去反向并联器件。
四、典型应用
- 汽车 12V 电源线、感应负载防护（需结合系统耐受能力和 ISO/SAE 要求校核）；
- 工业控制与电机驱动的输入电源浪涌抑制；
- 电信、网络设备的接口保护；
- 开关电源、逆变器和电池管理系统的过压保护。
五、选型与使用建议
- 工作电压选择：Vrwm（10 V）应略高于系统静态工作电压，避免常态触发；
- 考虑浪涌能量：Ppp 基于 10/1000 μs 波形，若遇到更陡波形（如 8/20 μs），需核对器件极限；
- 热管理：SMB 封装受 PCB 铜箔与散热面影响大，长期脉冲或重复冲击需评估结温并适当降容；
- 双向器件无需并联反向单元，便于保护交流或双向突波。
六、封装与焊接注意
- 封装：SMB（DO-214AA），适合自动贴装与回流焊工艺；
- 焊接：遵循厂家温度曲线，避免过热导致芯片破裂或钝化层失效；
- 储存与操作：防静电防潮，避免机械冲击，焊接后建议进行功能测试。
七、可靠性与测试
- 器件在标准测试下表现出低泄漏与稳定的击穿特性；
- 设计时建议进行实际系统级浪涌测试（按 IEC 或汽车相关标准）以验证整体保护效果。
SMBJ10CA 以其高能量吸收能力、低泄漏和快速响应，适用于要求稳健瞬态保护的多种系统，是对 10 V 级电源和信号线进行浪涌抑制的常用选择。

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.
