SMCJ22CA-AT/TR13（双向汽车级TVS二极管）产品概述
一、产品简介
SMCJ22CA-AT/TR13 是 Brightking（台湾君耀）出品的汽车级双向瞬态电压抑制（TVS）二极管，封装为 SMC（DO-214AB）。该型号适用于车载电源和信号线的浪涌、瞬态和静电放电（ESD）保护，具有高峰值脉冲功率和低反向漏流的特点，满足汽车级应用对可靠性与稳健性的要求。
二、主要电气参数
- 极性：双向
- 反向截止电压（Vrwm）：22 V
- 击穿电压（VBR）：24.4 V
- 钳位电压：35.5 V（在峰值脉冲条件下）
- 峰值脉冲电流（Ipp）：42.3 A
- 峰值脉冲功率（Ppp）：1.5 kW（典型脉冲条件下测得）
- 反向电流（Ir）：1 μA（在 Vrwm 条件下，典型）
- 防护等级：满足 IEC 61000-4-2（ESD）标准要求
三、主要特性与优势
- 双向结构，可直接用于交流或两极性瞬态场合（如车载信号线、CAN/LIN 总线）
- 高能量吸收能力，峰值脉冲功率 1.5 kW，能有效抑制高能浪涌和负载突变事件
- 低反向漏流（1 μA），在正常工作电压下几乎不影响系统待机功耗
- 钳位电压适中（35.5 V），在保护元件导通时对后端电路提供可靠的电压保护
- SMC 封装便于表面贴装生产，热耗散能力良好，适合汽车电子的可靠性设计
四、典型应用场景
- 汽车车身控制单元（BCM）、车载网关与域控制器的电源与信号保护
- CAN、LIN、FlexRay 等车载通讯线路防护
- 车载充电系统与车载电源母线的瞬态抑制
- 车载传感器与执行器的接口电路保护
- 工业控制、通讯基站、消费电子中需要高能量浪涌防护的直流/双向线路
五、布局与使用建议
- 尽量将 TVS 二极管靠近被保护端口或电源入口放置，缩短导线和走线长度以降低寄生电感
- 确保焊盘与散热地平面良好接触，必要时采用热填充或过孔增强散热
- 对于可能出现持续短路或过流情形的场合，应与熔断器/限流器配合使用；TVS 用于吸收短时脉冲，不作为长期短路保护手段
- 在高频或敏感信号路径上注意串联阻抗匹配，必要时添加阻尼或滤波元件
六、可靠性与合规
SMCJ22CA-AT/TR13 为汽车级产品系列，设计用于在苛刻环境下提供长期稳定的浪涌与静电保护。满足 IEC 61000-4-2 等抗静电标准，适配车规级设计要求。在选型时仍需结合具体的热环境、浪涌波形和系统级安全策略进行验证与可靠性试验。
七、订购与封装信息
- 品牌：Brightking（台湾君耀）
- 型号：SMCJ22CA-AT/TR13（AT/ TR13 常用于表明汽车级与卷带包装）
- 封装：SMC (DO-214AB)，适合自动贴装生产
结语：SMCJ22CA-AT/TR13 以其双向保护、高功率吸收和汽车级可靠性，适用于车载电源与通信线路的瞬态防护。实际设计应结合系统浪涌规范与热管理要求，进行电气与机械的完整验证。

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.
