SMCJ54CA/TR13 为 Brightking(台湾君耀)出品的双向 TVS(二极管瞬态抑制器),采用 SMC 表面贴装封装,专为保护直流/交流电源线及可逆极性电路免受雷击、开关瞬态或电缆耦合脉冲损害而设计。典型静态与冲击参数:反向截止电压(Vrwm)54V,击穿电压(Vbr)60V,钳位电压(Vc)87.1V(在指定峰值脉冲电流下),峰值脉冲电流 Ipp 17.3A,峰值脉冲功率 Ppp 1.5kW(基于 8/20µs 波形),反向漏电流 Ir 约 1µA(在 Vrwm 条件下)。
SMC 封装适合表面贴装大功率瞬态器件,机械强度与散热性能良好。双向结构无极性标识需求,但仍需注意焊接工艺(避免过热),并遵循厂家回流温度限制与储存防潮建议。长期可靠性会受重复冲击次数、脉冲能量和环境温度影响,建议在高温或多次冲击工况下参考厂方可靠性数据并适当降额使用。
总结:SMCJ54CA/TR13 为面向 48–54V 级别电源与可逆线路的高能量双向 TVS,具备 1.5kW(8/20µs)瞬态承受能力和较低漏电,适用于工业、通信与电源防护场景。选型与布局时应关注工作电压裕度、冲击波形与PCB散热设计,以保证长期可靠运行。

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.
