SMAJ160A 产品概述
一、产品简介
SMAJ160A 为 RUILON(瑞隆源) 出品的单向 TVS（瞬态电压抑制二极管），采用 SMA 封装，专为抑制瞬态过电压、吸收雷击与开关浪涌能量设计。器件工作稳定、响应快速，适用于各种工业电源及信号保护场合。
二、主要参数
- 极性：单向
- 反向截止电压 Vrwm：160 V
- 击穿电压 VBR：197 V
- 钳位电压 Vc（在 10/1000 µs 峰值脉冲下）：259 V
- 峰值脉冲电流 Ipp：1.5 A（10/1000 µs）
- 峰值脉冲功率 Ppp：400 W（10/1000 µs）
- 反向静态电流 Ir：1 µA（典型）
- 工作温度范围：-55 ℃ ~ +150 ℃
- 封装：SMA（表面贴装）
三、典型特性与优势
- 高能量吸收：在 10/1000 µs 浪涌条件下，Ppp 可达 400 W，能有效吸收中等能量浪涌。
- 低漏电：典型反向电流 1 µA，有利于低功耗系统长期在线运行。
- 宽温度范围：-55 ~ +150 ℃，适应恶劣工业环境。
- SMA 小体积封装，便于自动贴装与批量生产，且具备良好热传导与机械强度。
四、典型应用场景
- 工业电源线和直流母线保护（如 12V~150V 级别的系统）
- 通信设备、电源适配器、逆变器输入端的浪涌保护
- 电源模块、继电器驱动与工业控制器的输入端防护
- 需要小体积高可靠性的瞬态抑制场合
五、使用与注意事项
- 选型时保证工作电压低于 Vrwm（160 V），且正常工作时留下足够余量，避免频繁进入浪涌击穿区。
- 钳位电压 259 V 为在规定浪涌波形下的典型值，系统其他元件应能承受该电压。
- 浪涌能力受环境温度和焊接热历史影响，长期或重复浪涌会降低吸收能力，应根据实际应用考虑冗余或级联保护。
- 器件为单向型，安装时注意极性（SMA 封装的带标识端为阴极）。
六、封装与安装要点
- SMA 封装适用于回流焊工艺，推荐采用短、粗的走线将器件靠近被保护端子布置，以降低感性环路和提升抑制效率。
- 焊接工艺应参考厂商回流温度曲线，避免超出规定峰值温度以防损伤器件。
七、选型与可靠性建议
- 若系统可能遭受更高能量浪涌或重复冲击，建议选择更高 Ipp/Ppp 额定值或在输入端并联/级联多个保护器件。
- 对于关键系统，建议在 TVS 前端配合熔断器或限流元件以实现故障隔离，提高整体可靠性。
- 最终选型应以完整数据手册为准，包含浪涌曲线、热阻、封装尺寸及焊接规范。
如需完整电气曲线、封装图或推荐电路图，可提供进一步资料以便核对与应用设计支持。

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.
