SMBJ36CA 产品概述
一 产品简介
SMBJ36CA（UMW/友台半导体）是一款双向瞬态电压抑制器（TVS），专为工业及电子系统的浪涌与静电放电保护设计。器件采用SMB（DO-214AA）封装，具备高能量吸收能力和快速响应特性，可有效保护敏感元件免受瞬态过电压损害。
二 主要参数
- 类型：双向 TVS
- 反向截止电压（Vrwm）：36 V
- 击穿电压（Vbr）：40 V
- 钳位电压（Vclamp）：58.1 V
- 峰值脉冲功率（Ppp）：600 W（按厂方测试脉冲波形）
- 峰值脉冲电流（Ipp）：10.3 A
- 反向电流（Ir）：1 µA（典型）
- 防护等级：符合 IEC 61000-4-4（EFT）与 IEC 61000-4-2（ESD）
- 封装：SMB（DO-214AA）
三 特性与优势
- 高效能量吸收：600 W 峰值脉冲功率与 10.3 A 峰值电流能力，适合处理中等能量的浪涌事件。
- 双向保护：适用于交流线路或双极性瞬态，安装方便，无需极性区分。
- 低漏电流：反向电流仅 1 µA，利于低功耗电路长期并联保护。
- 快速响应：典型 TVS 响应速度可在纳秒级别触发，能迅速钳位过电压。
- 工业级兼容：通过 IEC 61000-4-2/4-4 相关抗扰度认证，满足工业环境抗干扰要求。
四 推荐应用场景
- 工业自动化 I/O 端口、通信接口的过压与静电防护；
- 电源输入端、继电器驱动及电机控制系统的浪涌抑制；
- 数据线、总线接口（如 RS-485、CAN）在恶劣电磁环境下的保护；
- 需双向保护的交流或对称信号线路。
五 选型与安装建议
- 选型要点：Vrwm（36 V）应高于线路正常工作电压，钳位电压（58.1 V）应满足被保护器件承受能力；若被保护器件耐压低于钳位值需选用更低钳位型号或在前端增加串联限流元件。
- 浪涌脉冲波形与器件额定 Ppp 的匹配很重要，确认脉冲宽度与厂方定义一致以保证吸能能力。
- PCB 布局：将 TVS 尽量靠近受保护端口与接地短路布线，保持低电感回路以降低钳位电压与提高抑制效率。
- 热管理：在高频繁冲击场景下注意封装散热，必要时提供铜箔散热或外壳散热路径。
六 封装与可靠性注意
SMB（DO-214AA）封装适合自动贴装与回流焊工艺，具有良好的机械强度。储存与焊接时避免超出厂家推荐的回流温度曲线，防潮处理按常规 SMD 元器件要求执行。长期可靠性与耐久性建议在实际应用中做加速寿命或重复脉冲验证。
总结：SMBJ36CA 以其可靠的双向保护、高能量吸收与工业级抗扰度，适合用于多类需防护浪涌与静电的电路，是工业与通信接口保护的实用选择。

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.
