SMAJ15CA 产品概述
一、产品简介
SMAJ15CA 为 YANGJIE（扬杰）出品的一款双向瞬态抑制二极管（TVS），采用 DO-214AC（SMA）封装，专为瞬态过电压和浪涌冲击保护设计。器件在典型10/1000μs冲击波形下，能承受高能量脉冲，适用于直流/交流双向保护场合。
二、主要参数
- 极性：双向
- 反向截止电压 Vrwm：15V
- 击穿电压 Vbr：18.5V
- 钳位电压 Vc（Ipp）：24.4V
- 峰值脉冲电流 Ipp：16.39A（10/1000μs）
- 峰值脉冲功率 Ppp：400W（10/1000μs）
- 反向电流 Ir：5μA（常温，Vrwm下）
- 封装：DO-214AC（SMA）
三、功能与优势
- 双向构造能同时抑制正负瞬态，适合交流线路或互联端口保护；
- 低反向泄漏电流（5μA）在静态条件下对电路影响小；
- 在10/1000μs标准浪涌下，24.4V的钳位性能可有效保护后级器件免受高压击穿；
- DO-214AC 封装便于自动化贴装与散热管理，机械强度好，可靠性高。
四、典型应用
适用于通信设备、电源输入端、汽车电子（非安全关键回路）、工业控制、接口保护（RS‑485、CAN、USB等）及其他需要双向浪涌防护的场合。
五、选型与使用建议
- 确认系统工作电压与 Vrwm 匹配，避免在常态下触发击穿；
- 考虑浪涌能量（10/1000μs）是否低于器件 Ppp 能力，必要时并联或采用更高能量器件；
- 为提高可靠性，注意 PCB 热回流路径与焊盘散热，避免长期过热；
- 在高频或高速信号线上使用时，评估寄生电容对信号完整性的影响。
以上为 SMAJ15CA 的核心介绍与使用要点，便于在设计阶段快速评估该 TVS 器件是否满足系统保护需求。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
