SMAJ170CA-TR 是意法半导体(ST)出品的一款双向瞬态电压抑制器(TVS),封装为 SMA(DO-214AC)。器件专为瞬态浪涌和静电放电(ESD)保护设计,常用于通信、电源和工业接口电路中对过压瞬态的防护。双向结构无需极性区分,适用于交流或双向信号线路的保护。
SMAJ170CA-TR 满足 IEC 61000-4-5 与 IEC 61000-4-2 标准,适用于要求符合这些抗扰度规范的设备。器件材料与工艺适配工业温度范围,可靠性与长期稳定性良好,但应避免重复超额能量冲击导致寿命下降。
如需器件的完整电气特性曲线、封装尺寸图及回流焊工艺建议,可参考 ST 官方数据手册以获取详尽参数与应用指导。

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.
