SMCJ170A/TR13是台湾君耀(Brightking)推出的单向瞬态电压抑制二极管(TVS),采用SMC(DO-214AB)表面贴装封装,专为中高压电路的瞬态过压防护设计。其核心功能是在电路遭遇雷击、开关浪涌、静电放电(ESD)等瞬态脉冲时,快速导通并钳位电压,避免后级敏感元器件(如微控制器、传感器、通信接口芯片等)被击穿损坏,广泛适配工业控制、汽车电子、通信设备等领域的防护需求。
该器件的参数围绕“过压防护可靠性”优化,核心指标及意义如下:
该封装为表面贴装式,尺寸紧凑(约3.5mm×1.8mm×1.0mm),适合高密度PCB布局;引脚间距合理,兼容回流焊、波峰焊等自动化焊接工艺,且抗机械应力性能较好,适配批量生产。
台湾君耀是全球知名防护器件厂商,产品通过ISO/TS 16949、IEC等国际认证,一致性与稳定性突出;SMCJ系列采用优化芯片设计,多次浪涌冲击后性能无衰减,降低电路维护成本。
结合参数与封装优势,SMCJ170A/TR13的典型应用包括:
SMCJ170A/TR13的核心优势在于:宽温范围适配严苛环境、低漏电流不影响正常电路、高脉冲功率支撑中强度防护、SMC封装适合高密度设计。作为中高压TVS二极管,其在工业、汽车、通信等领域的过压防护中具有较强适用性,是替代同类进口器件的高性价比选择。

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.
