SMA6J13CA — Littelfuse（美国力特）600W 双向 TVS 二极管 概述
一、产品简介
SMA6J13CA 是 Littelfuse 推出的双向瞬态电压抑制器（TVS）/ESD 保护二极管，封装为 DO-214AC（SMA）。该器件专为保护敏感电子元件免受静电放电（ESD）、浪涌和瞬态过电压损害而设计，额定峰值脉冲功率 600W，适用于工业、通信及消费类设备的电源与信号线防护。
二、主要参数
- 极性：双向
- 反向截止电压 Vrwm：13V（±5%）
- 击穿电压 Vbr：14.4V（典型）
- 钳位电压 Vc：21.5V（在峰值脉冲电流 Ipp 条件下）
- 峰值脉冲电流 Ipp：29A
- 峰值脉冲功率 Ppp：600W
- 反向电流 Ir：1μA（常温，静态漏电）
- 工作温度范围：-65℃ ~ +150℃
- 防护等级：符合 IEC 61000-4-2（ESD）标准
- 封装：DO-214AC（SMA）
- 类型：TVS / ESD 保护二极管
三、主要特性与优势
- 高功率吸收能力：600W 峰值脉冲功率能在短时冲击下可靠吸收大量能量，提升系统抗浪涌能力。
- 低钳位电压：21.5V 的典型钳位值（在 Ipp 条件下）能有效降低浪涌时对后端器件的应力。
- 低漏电流：1μA 的低反向电流保证在待机和正常工作时对电源线或信号线的影响最小。
- 宽温度范围：-65℃ 至 +150℃，适合在恶劣环境和高温场景长期工作。
- 双向保护：可对称处理正负极性瞬变，适用交流链路或需要双向保护的信号线。
四、典型应用
- USB、HDMI、以太网等高速接口的端口保护
- 电源输入与电压轨的浪涌防护
- 通信设备、工业控制、仪表及消费类电子的ESD保护
- 严苛环境下的系统（工业级、工控、户外通信设备）
五、封装与布局建议
- 封装为 DO-214AC（SMA），支持表面贴装，便于自动化组装。
- 布局时尽量将 TVS 靠近需要保护的连接器或受保护节点，缩短走线以降低寄生电感。
- 对于高能量冲击，可在输入端配合串联电阻或共模电感限制瞬态电流。
- 注意焊接与散热设计，避免超过器件峰值功率和热耗散能力。
六、可靠性与选型提示
SMA6J13CA 来自 Littelfuse（美国力特），品质与一致性有保障。选型时注意匹配系统最大运行电压（Vrwm）与实际工作电压，预留一定余量避免频繁触发。若系统需更高能量吸收或更低钳位，可考虑并联或选用更高功率等级的 TVS，但并联时需注意均流与热管理。总体而言，SMA6J13CA 在中高能量 ESD/浪涌保护场景中提供了性价比高且稳定的解决方案。

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.
