SMAJ16A/TR13 是台湾君耀(Brightking)出品的一款单向瞬态电压抑制器(TVS),封装为常用的SMA(DO-214AC)。器件针对线路瞬态过电压和浪涌脉冲提供快速钳位保护,适用于汽车电子、通信设备、电源输入端以及一般工业控制场合的过压防护。产品以高能量吸收能力与宽工作温度范围著称,适合苛刻环境下的可靠保护需求。
SMA(DO-214AC)封装,体积小、焊接可靠,便于自动贴装与回流焊工艺。后缀/TR13 表示卷装(Tape & Reel)包装,适合SMT大批量生产。推荐焊盘尺寸和散热铜箔按厂商样本设计,以保证最佳热散及焊接可靠性。
优点包括高峰值功率吸收(400 W@10/1000 μs)、低反向漏电和宽温度工作范围(-65~150 ℃),适合高能量浪涌场合。限制在于钳位电压相对固定(26 V),对要求更低钳位电压或更高脉冲电流的场合需选择更高规格的TVS或并联/组合方案。
SMAJ16A/TR13 适合用于对16 V 级别直流线或信号线进行高能量瞬态保护的场合,尤其在要求体积小、可回流焊和耐高温的工业或车载项目中表现优良。选型时请核对系统最大承受电压、允许钳位电压及脉冲能量需求,并结合PCB 布局与散热条件进行共同验证。如需更高浪涌电流或更低钳位值,可联系供应商获取系列其它型号对比建议。

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.
