SMCJ40CA/TR13 产品概述
一、产品简介
SMCJ40CA/TR13 是 Brightking（台湾君耀）出品的一款双向瞬态电压抑制（TVS）二极管，封装为 SMC (DO-214AB)。该器件针对工业级浪涌与静电放电保护设计，额定反向截止电压 Vrwm 为 40V，典型钳位电压为 64.5V，击穿电压约 44.4V，峰值脉冲电流 Ipp 为 23.3A，峰值脉冲功率 Ppp 达 1.5kW，反向漏电流仅 1µA，工作温度范围宽 (-65℃ ~ +150℃)，符合 IEC 61000-4-2 静电放电抗扰度要求。
二、主要性能特点
- 双向结构，适用于交流或双向脉冲冲击保护。
- 高峰值功率 (1.5kW) 与较大峰值脉冲电流（23.3A），能承受工业级浪涌。
- 低钳位电压（64.5V），在浪涌发生时对下游元件提供有效限制。
- 宽温区、低漏电流（1µA），适合要求高可靠性的长期运行场合。
- 标准 SMC 封装，便于自动化贴片与散热管理。
三、典型应用场景
- 工业控制总线、继电器驱动及电源输入端的浪涌保护。
- 通讯设备、电源模块、逆变器及电池管理系统的瞬态抑制。
- 需要符合 IEC 61000-4-2 静电防护的终端设备与测试点。
四、电气与机械参数（要点）
- 极性：双向；封装：SMC (DO-214AB)；品牌：Brightking。
- Vrwm：40V；Vbr（击穿）：44.4V；Vc（钳位，典型）：64.5V。
- Ipp（峰值脉冲电流）：23.3A；Ppp（8/20µs）：1.5kW。
- Ir（反向电流）：1µA；工作温度：-65℃ ~ +150℃；符合 IEC 61000-4-2。
五、PCB 布局与使用建议
- 虽为双向器件，但仍建议将 TVS 置于保护点与接地（或回流电位）之间，靠近被保护元件的进线端。
- 缩短导线与走线长度，减小串联电感以提升钳位效果。
- 为充分散热，SMC 封装应配合足够的铜箔面积与通孔散热。
- 在频繁或高能量脉冲场合，应考虑并联或级联保护器件以延长寿命。
六、选型与可靠性提示
- 选择时确认 Vrwm 高于系统工作电压并保留一定裕量，但钳位电压须低于被保护器件耐压。
- 对重复冲击环境进行寿命评估：长期高温或频繁冲击会降低承受能力，应适当降额使用。
- 需要认证或批量采购时，建议向厂商索取完整数据手册、冲击曲线与可靠性测试报告以便验证。

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.
