SMBJ30CA-AT/TR13 产品概述
一、产品简介
SMBJ30CA-AT/TR13 是 Brightking（台湾君耀）出品的双向瞬态电压抑制器（TVS），采用 SMB（DO-214AA）封装，专为瞬态过压和静电放电（ESD）保护设计。该器件对两极方向均具有保护能力，可在瞬态冲击下快速箝位，保护下游电路免受破坏，适用于工业、通信、电源及消费电子等环境。
二、主要电气参数
- 极性：双向
- 反向截止电压 VRWM：30 V
- 击穿电压 Vbr：33.3 V
- 钳位电压 Vc：48.4 V（于额定脉冲条件下）
- 峰值脉冲电流 Ipp：12.4 A
- 峰值脉冲功率 Ppp：600 W（10/1000 μs 或制造商指定波形下）
- 反向电流 Ir：1 μA（常温下）
- 工作温度范围：-55 ℃ ~ +150 ℃
- 防护等级：符合 IEC 61000-4-2 ESD 要求
- 封装：SMB（DO-214AA）
三、典型特性与产品优势
- 双向结构：可直接用于交流耦合或双向数据/电源线上，无需外加极性元件。
- 高能量吸收：600 W 峰值脉冲功率，能承受较强的瞬态浪涌与浪涌电流冲击。
- 低泄漏：典型反向电流仅 1 μA，有利于对高阻或精密电路的保护，减少静态功耗。
- 宽温度适应性：-55 ℃ 至 +150 ℃ 的工作范围，适应严苛环境和工业级应用。
- ESD 抗扰度：满足 IEC 61000-4-2，有效抑制接触与空气放电造成的损害。
四、典型应用场景
- 电源输入保护（DC/AC 线路的浪涌抑制）
- I/O 接口、串口与通信链路的浪涌与 ESD 防护
- 工业控制设备、仪器仪表及测试设备的过压保护
- LED 驱动、电池管理与电源模块的瞬态抑制
五、封装与安装建议
- 封装为 SMB（DO-214AA），便于手工焊接与自动化贴装，常用卷带（Tape & Reel）出货，适配 SMT 产线。
- 布局建议：将 TVS 尽量靠近被保护端口布置，走线短且宽，增加 PCB 铜面积以利散热。
- 焊接工艺：推荐遵循无铅回流温度曲线，不宜超过器件最高额定温度；避免多次重复加热。
六、选型与可靠性提示
选型时应确认正常工作电压低于 VRWM（30 V）并留有足够裕量；同时确保钳位电压（48.4 V）在被保护元件可耐受范围内。若应用中存在反复高能脉冲或高频冲击，建议评估并采用冗余或并联设计以提高可靠性。器件已通过 IEC 61000-4-2 测试，适用于需要 ESD 抗扰度的场合，但在特殊标准或车规级要求下应参考制造商完整规格书与认证信息。

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.
