SMDJ12CA/TR13 是 Brightking(台湾君耀)推出的一款双向瞬态电压抑制(TVS)二极管,封装为 SMC(DO-214AB)。该器件针对瞬态浪涌和雷击/浪涌事件提供快速钳位保护,适用于12V级电源及信号线的过电压防护。产品在标准脉冲测试条件下展现出高能量吸收能力和低泄漏电流,是工业、通信与汽车等系统的常用过压保护元件。
以上参数表明该器件能在12V系统中,在短时大电流浪涌下将电压钳制在约20V以内,同时保持微安级的静态漏电。
SMC(DO-214AB)为表面贴装大功率封装,具有较大的焊盘面积和良好的热扩散能力。该封装利于在 PCB 上通过宽铜箔和热沉结构快速导出浪涌能量,适合需要高脉冲能量处理能力的应用场景。器件适用于自动贴片、回流焊工艺。
如需进一步的电路示例、典型波形测试数据或 PCB 推荐封装尺寸,请提供是否需要数据手册或具体应用场景,我可继续协助分析与推荐。

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.
