SMAJ36CA — 双向瞬态抑制二极管（TVS/ESD）产品概述
一、产品简介
SMAJ36CA 是 GOODWORK（固得沃克）推出的一款双向 TVS/ESD 器件，封装为 SMA (DO-214AC)。器件专为抑制静电放电和瞬态电涌设计，能够在瞬时高能脉冲下保护敏感电子元件和电路。器件工作温度范围宽（-55℃ ~ +150℃@Tj），适合工业级和严苛环境应用。
二、主要电气参数与特性
- 钳位电压（典型）：58.1 V（在规定峰值脉冲电流下的钳位表现）
- 击穿电压（Vbr）：40 V（标称）
- 反向工作电压（Vrwm）：36 V
- 峰值脉冲功率（Ppp）：400 W（脉冲规格按行业常用脉冲测试）
- 峰值脉冲电流（Ipp）：6.9 A
- 反向漏电流（Ir）：5 μA（典型）
- 极性：双向（适合交流或任意极性瞬态）
- 封装：SMA (DO-214AC)，便于表面贴装与自动化生产
以上参数表明 SMAJ36CA 在中等能量浪涌条件下具有良好的吸收能力与低漏电特性，适合保护 30–40 V 级别的电源总线和接口。
三、典型应用场景
- 电源线与总线防护：36 V 额定工作电压的直流/交流电源输入、车载电源或工业电源防浪涌。
- 接口与通讯线路：RS-485、CAN、以太网端口等需要双向保护的差分线路。
- 工业控制与自动化设备：传感器端、驱动器输入及现场总线接口的浪涌/ESD 防护。
- 消费类与嵌入式设备：对抗线路干扰与静电冲击，提升系统可靠性。
四、安装与使用建议
- 布线：将 TVS 置于被保护器件的靠近端，走线尽量短且回路面积小，减小串联感抗与寄生电感。
- 接地：对地防护时保证良好的接地平面或参考地，焊盘与地平面需低阻抗连接。
- 焊接工艺：SMA 封装支持回流焊与波峰焊，遵循厂商推荐的温度曲线以避免封装应力。
- 环境和可靠性：工作温度可达 +150℃（Tj），但建议按应用场景进行热管理与功率余量设计，避免在高温下长期满载脉冲。
五、选型参考与注意事项
- 双向 vs 单向：若用于直流电源保护且只需单向钳位，单向 TVS 在钳位电压与漏电控制上可能更优；若线路可能出现正负极性瞬态或用于交流信号，双向 SMAJ36CA 更合适。
- 能量裕量：根据系统可能遇到的最大脉冲能量选择合适的 Ppp 与 Ipp 余量，必要时并联或选用更高功率等级的器件。
- 测试条件：实际钳位电压受测试脉冲波形、源阻抗和环境温度影响，选型时应参考完整数据手册并在目标系统中验证。
- ESD 操作：器件本身用于抗静电，但在装配与调试过程中仍应保持 ESD 防护规范。
SMAJ36CA 以其 36 V 级别的反向工作电压、400 W 峰值脉冲功率和双向抑制特性，为工业、通讯和汽车电子等多种场景提供可靠的瞬态浪涌保护。选购时请结合具体脉冲波形与系统要求，参考 GOODWORK 的完整技术资料以完成最终设计。

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.
