SMAJ15CA 是 TECH PUBLIC(台舟电子)推出的一款单路瞬态抑制二极管(TVS),封装为 DO-214AC(SMA)。器件面向瞬态浪涌与电气冲击保护场景设计,适用于中低电压直流供电系统及信号线防护。其反向截止电压(Vrwm)为 15V,击穿电压约 18.5V,钳位电压 24.4V(在指定冲击条件下),在 10/1000µs 波形下峰值脉冲功率可达 400W,单次脉冲峰值电流为 16.4A,适配常见工业与消费类浪涌抑制需求。
SMA 封装具备较好的散热能力与机械强度,适合常规 SMT 加工流程。器件在推荐温度范围内能保持稳定的防护特性;在高温或高能量冲击下建议进行适当的热管理设计,并按系统级防护策略进行器件并联或级联以分摊能量。
此型号封装为 DO-214AC(SMA),便于标准 SMT 生产线批量贴装。采购时请确认 TECH PUBLIC(台舟电子)原厂或授权代理,注意器件批次与 RoHS 等合规性证书以满足项目需求。
总结:SMAJ15CA 是一款面向 12V 级别电源与接口保护的高能量吸收 TVS 二极管,具有低泄漏、宽温度范围与标准 SMA 封装,适合工业、车规与民用电子的脉冲浪涌防护。

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.
