SMCJ15CA 是一款双向瞬态电压抑制二极管(TVS),由 BORN(伯恩半导体)提供,封装为 SMC(DO-214AB)。该器件针对瞬态浪涌和脉冲过压事件提供高能量吸收能力,适用于需要抗雷击、开关瞬变或线路感应浪涌保护的电源与信号应用。器件典型应用包括汽车 12V 系统、工业电源保护、LED 驱动器和各类直流母线保护。
注:所有数值应以供应商最终数据手册为准,特别是在不同测试条件或温度下参数会有变化。
SMC(DO-214AB)封装适合自动化贴装和回流焊/波峰焊工艺。建议遵循制造商给出的焊接曲线与储运说明,注意防潮处理及合适的回流温度/时间以保证焊点可靠性与器件性能稳定。
双向 TVS 通常并联接入被保护线对:在直流/交流电源总线或信号线两端直接并联连接(正负之间或线—地之间,视系统接法而定),在出现正向或反向过压时迅速导通并将尖峰电流引导至地/对端,保护下游电路。
选择时除 Vrwm、Vclamp、Ipp、Ppp 和 Ir 外,还需关注结电容、响应时间、工作温度范围及包装一致性。若需不同钳位或更高能量吸收,应查找同类封装中更高 Ppp 或更低 Vclamp 的型号。采购时确认 BORN 的最新数据手册与测试报告。
结语:SMCJ15CA 以其 15 V 的工作电压、24.4 V 的钳位电压与 1.5 kW 的瞬态吸收能力,适合多种中低压电源与信号线的抗浪涌保护。具体设计与可靠性评估应结合完整的应用环境参数,并以制造商数据手册为最终依据。

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.
