SMCJ11CA/TR13 是台湾 Brightking(君耀)推出的一款双向瞬态电压抑制器(TVS),采用 SMC(DO-214AB)封装。该器件为 11V 额定反向工作电压(VRWM=11V)双向保护型,适用于脉冲浪涌保护和瞬态冲击抑制。器件在极端环境下仍具有稳定的电气特性,工作温度范围为 -65℃ 至 +150℃,适合工业级及高应力电源/信号保护场合。
SMCJ11CA 为双向 TVS,意味着在正负极性瞬态过压时均能提供对称钳位保护,适合交流线路或可反向的直流系统。器件在电压超过 VBR(≈12.2V)时进入雪崩导通状态,将瞬态能量以钳位电压(≈18.2V)形式消散,从而限制后端电路受压。峰值脉冲电流 82.5A 与峰值脉冲功率 1.5kW 表示在短时大能量浪涌(如雷击诱发脉冲、开关突波)时具有较高的吸收能力。静态反向电流仅 1µA,确保在正常工作电压下对系统影响极小。
SMCJ11CA/TR13 适用于需要较大吸收能量和高温稳定性的场合。在选型时应确认:系统正常工作电压与 VRWM 的匹配(若系统为 12V 级,11V VRWM 为常见选择),器件钳位电压对于受保护元件的耐压是否安全,以及所面对的浪涌幅值与器件峰值吸收能力是否相匹配。若需符合特定行业认证(如车规 AEC-Q、UL 等),请向供应商索取相应证书与完整数据手册以做最终确认。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
