5.0SMDJ20CA/TR13 产品概述
一、产品简介
5.0SMDJ20CA/TR13 是 Brightking（台湾君耀）生产的一款双向瞬态抑制二极管（TVS），封装为 SMC（DO-214AB），用于对 20V 等级电源或信号线提供高能脉冲和静电放电保护。器件设计用于在瞬态事件发生时迅速钳位电压、吸收能量并将危险电压限制在安全范围内，保护下游电子器件免受损坏。
二、主要参数
- 极性：双向
- 反向截止电压 Vrwm：20V
- 击穿电压 VBR：22.2V（典型）
- 钳位电压（Ipp）：32.4V
- 峰值脉冲电流 Ipp：155A
- 峰值脉冲功率 Ppp：5kW
- 反向电流 Ir：5µA（常温静态）
- 防护等级：符合 IEC 61000-4-2（ESD）
- 封装：SMC（DO-214AB）
三、关键特性
- 双向结构，适用于交流或双向脉冲环境，无需区分极性。
- 高能量吸收能力（Ppp ≈ 5kW）与较大峰值脉冲电流，能应对高能瞬态浪涌。
- 低漏电流（Ir ≈ 5µA），对待保护电路静态功耗影响小。
- 钳位电压控制良好，在指定冲击下将电压限制在约 32.4V，保护敏感器件免受过压。
- SMC 封装便于表面贴装和自动化生产，具有良好散热能力。
四、典型应用
- 电源输入防护（20V 级别直流或低压交流）
- 通信接口和数据线过压/静电保护
- 工业控制、车载电子（需核查车规要求）、消费电子和电源模块的浪涌抑制
- 符合 IEC 61000-4-2 要求的 ESD 防护设计
五、封装与可靠性建议
SMC（DO-214AB）封装提供较大焊盘面积，有利于脉冲能量散热与机械强度。建议在布局时提供足够的铜箔散热区域（焊盘下方和散热过孔），并尽量将 TVS 靠近被保护的接口或器件放置以缩短传输路径，提升保护效果。
六、使用与注意事项
- TVS 设计用于瞬态事件，不应作为连续限流器长期承受最大脉冲功率。
- 核对实际应用中的浪涌波形与器件测试波形匹配，必要时预留安全裕度。
- 在高频或高速信号线上使用时注意寄生电容影响；在敏感高速线路上需评估对信号完整性的影响。
- 对于车规或更严苛环境，请核实器件是否满足相应资格认证。
七、选型建议
如需在 20V 等级电源或接口上提供强力瞬态抑制且要求表贴工艺，5.0SMDJ20CA/TR13 是可靠选择。若应用有更高持续耐受或温度、车规要求，可咨询厂商获取更详尽的器件曲线与认证信息。

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.
