SMBJ36A 产品概述
一、主要参数与特性
SMBJ36A 为友台半导体（UMW）推出的一款双向瞬态电压抑制二极管（TVS），针对瞬态过压和静电放电提供快速钳位保护。主要电气参数包括：反向截止电压 Vrwm = 36V，击穿电压 Vbr ≈ 40V，钳位电压 Vcl = 58.1V，峰值脉冲电流 Ipp = 10.3A，峰值脉冲功率 Ppp = 600W（测试脉冲条件下），反向漏电流 Ir = 1μA。器件采用 SMB（DO-214AA）封装，极性为双向，能够在正负两极方向上对瞬态进行对称钳位保护。
二、性能与可靠性
SMBJ36A 对电快速瞬变（EFT）和静电放电（ESD）具有良好防护能力，符合 IEC 61000-4-4 与 IEC 61000-4-2 标准要求。低漏电（1μA）特性使其在休眠或高阻状态下对电路影响极小；较高的峰值脉冲功率（600W）与峰值脉冲电流（10.3A）确保在工业电源浪涌、开关反激或雷击感应等场景下有效吸收能量并钳制电压。
三、封装与机械特性
采用 SMB（DO-214AA）塑封封装，适合常规表贴工艺（SMT）与自动化组装。封装尺寸与热阻特性适中，便于在有限空间内靠近被保护线路布局以减小寄生感抗。双向结构无需关注极性，适用于交流或无极性的保护场合。
四、典型应用场景
- 工业36V母线与控制电源防护
- 串行通信接口、I/O 端口和传感器线路的瞬态抑制
- 电机驱动、继电器回路及电源模块的浪涌保护
- 工业自动化、楼宇控制、仪器仪表等需要抗干扰与ESD防护的系统
五、设计与安装注意事项
为发挥最佳保护效果，TVS 应尽量靠近被保护端口焊接，最小化引线和走线电感。对于可能的重复高能脉冲场景，应配合熔断器或限流元件防止器件过热失效。焊接时遵循厂家推荐的回流温度曲线，避免过高温度和长时间回流；储存和使用应注意湿敏等级及防潮处理。
六、选型与替代建议
当工作电压接近或低于 36V 且需双向保护时，SMBJ36A 为可靠选择；若需更高能量吸收能力或更低钳位电压，可考虑升级至更大封装或更高Ppp等级的TVS。选型时应兼顾系统最大工作电压、允许钳位电压以及浪涌波形与频率，以确保长期可靠运行。

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.
