SMAJ26CA 产品概述
一、产品简介
SMAJ26CA 是华轩阳电子（HXY MOSFET）推出的一款双向瞬态电压抑制器（TVS），采用 SMA（DO-214AC）封装。器件面向对26V工作电压附近的电源线与信号线的浪涌、雷击和静电放电保护需求，能够在瞬态过电压出现时迅速钳位，保护下游敏感元件。
二、电气参数与性能
- 极性：双向（可对正、负极性瞬态同时钳位）
- 反向截止电压 Vrwm（稳态工作电压）：26V
- 击穿电压（Vbr）：28.9V 至 31.9V（典型/范围）
- 峰值脉冲电流 Ipp：9.5A
- 峰值脉冲功率 Ppp：400W（标称脉冲能量能力，按标准浪涌测试条件）
- 钳位电压 Vc：42.1V（在指定 Ipp 条件下测得）
- 反向漏电流 Ir：≤1 μA（在 Vrwm 条件下）
三、主要特性
- 快速响应：在瞬态事件发生时即时进入雪崩钳位状态，限制电压涨幅。
- 双向保护：适合两极性浪涌或交流信号线应用，无需两个器件并联。
- 高能量吸收能力：Ppp=400W，能够承受常见雷击/浪涌事件的短脉冲能量（需按脉冲次数与间隔做选型）。
- 低漏电：Ir≈1μA，有利于对低功耗系统的影响最小化。
四、封装与机械特性
- 封装：SMA（DO-214AC），表面贴装，适配自动贴片生产线。
- 适用场合：体积小、易于布板的保护器件，适合商业和工业电子设备。
- 施工建议：焊盘设计应参考 DO-214AC 标准尺寸，保持管脚与接地/电源线短路径以降低寄生阻抗。
五、典型应用场景
- 车载电子（对26V车载总线有良好匹配）
- 通信设备电源防护、基站与路由器电源输入侧
- 工业控制器、变频器前端的浪涌保护
- 电源适配器、充电设备及其他需要瞬态过压抑制的场合
六、推荐使用与注意事项
- 工作电压：推荐电路常态电压不超过 Vrwm=26V，以保证器件处于非导通状态；频繁接近极限会增加漏电与发热。
- 能量与重复率：Ppp 与 Ipp 为脉冲规格，长时间或高重复率浪涌会导致热累积并缩短寿命，应结合系统能量与热设计选型与散热。
- PCB 布局：保护器件应靠近受保护端口放置，走线短而粗，良好接地以提高钳位效率。
- 测试条件：钳位电压与峰值电流在特定脉冲波形下测得，实际值随脉冲形态与环境温度会有差异。
- 储存与焊接：遵循常规无铅回流工艺与制造商推荐的温度曲线，避免超时暴露高温。
SMAJ26CA 以其双向钳位能力、较高脉冲能量吸收和小型表贴封装，是对26V级电源与信号线进行可靠瞬态保护的实用选择。

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.
