SMCJ70CA/TR13（Brightking）产品概述
SMCJ70CA/TR13 是台湾 Brightking（君耀）出品的一款双向瞬态抑制二极管（TVS），封装为SMC（DO-214AB），用于对高能脉冲瞬变电压进行钳制保护，适合工业、通信及电源系统的浪涌防护需求。
一、主要电气参数
- 极性：双向（适用于正负双极性瞬态）
- 反向截止电压 Vrwm：70 V
- 击穿电压 Vbr：77.8 V（典型）
- 钳位电压 Vcl：113 V（在峰值脉冲电流 Ipp 下）
- 峰值脉冲电流 Ipp：13.3 A
- 峰值脉冲功率 Ppp：1.5 kW（制造商标称，测试波形详见数据手册）
- 反向电流 Ir：1 μA（在 Vrwm 条件下）
- 工作温度范围：-65 ℃ ~ +150 ℃
- 类型/封装：TVS / SMC（DO-214AB）
二、主要特性与优势
- 双向结构能够直接抑制双极性或交流源产生的瞬态电压，无需额外反向并联元件；
- 高钳位电压与大功率吸收能力（1.5 kW）相结合，适合吸收较高能量的雷击或开关瞬变；
- 低漏电（1 μA）保证静态功耗小，不影响正常工作电压下的系统性能；
- 宽工作温度范围及SMC大封装有利于散热和长期可靠性。
三、典型应用场景
- 工业电源母线和DC-DC变换器的过压保护（尤其70 V 级别附近的直流系统）；
- 通信设备、基站和传输接口的浪涌保护；
- 电机驱动、逆变器和太阳能逆变系统的脉冲抑制；
- 电池管理及48 V配电系统的外部瞬态防护（需根据系统最大静态电压合理选型）。
四、PCB布局与散热建议
- TVS 两端走线应尽量短且粗，降低寄生电感以提高钳位效果；
- SMC 封装需配合足够的铜箔热沉区域，扩大铜箔面积并增加通孔散热到下层；
- 靠近受保护器件放置，优先靠近受害节点布置以缩短能量传导路径；
- 对于反复冲击场合，考虑增加阻尼或串联限流器件以分担热应力。
五、选型与可靠性注意事项
- 确认系统静态工作电压低于 Vrwm（70 V），否则 TVS 会长期导通并损坏；
- 钳位电压 113 V 是在指定 Ipp 下测得，实际钳制水平受 PCB 寄生影响，需留有余量；
- 对重复脉冲或多次冲击场景，应参考制造商能量循环寿命和热稳定性数据；
- 储存与焊接按常规半导体元件处理，避免超出最高结温并注意潮湿防护。
SMCJ70CA/TR13 提供了一种在中高电压直流和交流场合下，结合高能量吸收与低漏电特性的实用保护方案。具体电气性能和测试条件建议参阅 Brightking 官方数据手册以确保在目标应用中的可靠性与合规性。

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.
