SMCJ75CA/TR13 是 Brightking(台湾君耀)出品的一款双向瞬态电压抑制器(TVS),采用 SMC(DO-214AB)封装。该器件针对瞬时过电压、雷击和开关瞬变等脉冲能量事件提供双向夹断保护,适用于工业电源线、直流母线、逆变器接口及通讯/控制系统的浪涌保护需求。TR13 后缀通常表示卷带(Tape & Reel)自动化贴装包装,便于SMT生产线使用。
以上参数体现了该型号在高能量浪涌事件下的吸能能力与钳位效能,适合中高电压等级的防护场景。
SMC(DO-214AB)封装提供良好的热扩散路径与机械强度,适合波峰或回流焊工艺。实际使用时应关注功率耗散与热阻:在连续或重复脉冲条件下,需配合良好散热的PCB布局(加大焊盘铜面积、增加热穿孔)以防止局部过热与器件退化。
如需更详细的参数曲线(V-I 特性、钳位随脉冲幅度变化、热阻 RθJA 等)或样片测试计划,我可以根据具体测试条件帮您制定验证方案。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
