SMAJ8.5CA 产品概述
一、产品概述
SMAJ8.5CA 是 YANGJIE（扬杰）推出的一款双向瞬态电压抑制器（TVS），封装为 DO-214AC（常见的 SMA 类表贴封装）。器件针对脉冲突波和浪涌事件提供快速钳位保护，适用于敏感电子电路的过压防护场合，具有响应快、钳位电压低、漏电流小等典型特性。
二、主要参数
- 极性：双向（Bidirectional）
- 反向截止电压 Vrwm：8.5 V
- 击穿电压 Vbr：10.4 V
- 钳位电压 Vc（典型）：14.4 V
- 峰值脉冲电流 Ipp：27.78 A（10/1000 μs 波形）
- 峰值脉冲功率 Ppp：400 W（10/1000 μs）
- 反向电流 Ir：10 μA（在 Vrwm 下）
- 类型：TVS（瞬态电压抑制器）
- 封装：DO-214AC（SMA 类）
三、关键特性
- 双向结构可在正负瞬态电压下工作，适合交流或双极性信号线保护。
- 低漏电流（10 μA），适用于对静态功耗敏感的电源和接口线路。
- 高能量吸收能力（400 W @10/1000 μs）和较大脉冲电流承受能力，能抵御雷击感应和开关浪涌等高能瞬态。
- DO-214AC 表贴封装便于批量贴装和良好焊接可靠性。
四、典型应用场景
- 汽车电源和车载通讯接口（需考虑系统工作电压匹配）。
- 工业控制、仪表、继电器驱动回路的过压防护。
- 电源输入端、DC-DC 模块、接口保护（USB、RS-485、串口等双向信号线）。
- 通信基站、安防设备等易受雷击感应的场合。
五、安装与散热注意事项
- 建议按器件厂商推荐的 PCB 焊盘和焊接工艺加工，以保证良好热传导和机械强度。
- 大能量吸收时热量集中，必要时在器件附近布置热铜箔或加装散热结构，并避免长期重复大能量冲击。
- 焊接温度和回流曲线应符合封装材料规范，避免过热导致封装或结线损伤。
六、选型建议与可靠性
- 选型时优先确认系统常态工作电压与 Vrwm 匹配；8.5 V 的稳压电压适合低压电源或对 12 V 系统做局部保护时需评估钳位后电压对系统的影响。
- 注意钳位电压 14.4 V 为峰值钳位，实际能否保护下游元件需结合其耐压裕量评估。
- 如有更高能量或更低钳位需求，可考虑更高 Ppp 或更低 Vc 的型号。
- YANGJIE 品牌器件通过常规可靠性测试，适合量产应用；关键场合可咨询厂商获取完整认证与测试报告。

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.
