SMCJ18CA/TR13（29.2V）TVS二极管产品概述
一、产品简介
SMCJ18CA/TR13 是 Brightking（台湾君耀）出品的双向瞬态电压抑制（TVS）二极管，封装为 SMC（DO-214AB）。额定反向工作电压（Vrwm）18V，典型击穿电压22.1V，钳位电压约29.2V（在额定脉冲条件下）。该器件针对瞬态雷击与浪涌具有高吸收能力，适合工业与通讯电源保护。
二、关键电气参数
- 极性：双向（适用于交流/对称脉冲保护）
- 反向截止电压 Vrwm：18V
- 击穿电压 Vbr：22.1V（典型）
- 钳位电压 Vc：29.2V（在指定脉冲条件下）
- 峰值脉冲电流 Ipp：51.4A
- 峰值脉冲功率 Ppp：1.5kW（10/1000µs 波形）
- 反向电流 Ir：≤1µA（在 Vrwm 下）
三、主要特性与优势
- 高脉冲能量吸收能力（1500W @10/1000µs），可承受雷电与开关浪涌。
- 低漏电流（1µA 级），对低功耗电路影响小。
- 双向结构，适合需要对称保护的线路（如差分信号、交流输入）。
- SMC 封装便于自动贴装与散热，兼顾机械强度与热耗散。
四、典型应用场景
- 直流或交流电源总线保护（12V/24V 系统）
- 通信设备接口与以太网供电（需差分/双向保护场合）
- 工业控制、楼宇自动化与仪表防雷浪涌防护
- 电源适配器、充电桩等对突发浪涌有要求的模块
五、选型与应用建议
- 确认工作电压不超过 Vrwm（18V）；若系统稳态电压接近 Vrwm，应留有余量以防误触发。
- 依据最大浪涌能量选择并联/级联保护或更高等级 TVS；连续反复冲击会降低器件寿命，应考虑熔断器或限流器配合。
- 注意封装散热与PCB铜箔面积：良好散热可提高脉冲承受能力和可靠性。
- 生产采购时优先选择原厂或授权代理，TR（Tape & Reel）封装利于SMT贴片组装。
本产品适合对瞬态耐受能力要求高且需双向保护的场合，合理布局与配套防护元件能有效延长系统寿命并提升抗干扰性能。若需更详细的 I-V 曲线、封装尺寸与焊接工艺，请参考 Brightking 官方数据手册或联系供应商获取样片测试资料。

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.
