SMBJ36A(DOWO/东沃)产品概述

一、产品简介

SMBJ36A 为 DOWO(东沃)推出的一款高能量瞬态电压抑制二极管(TVS),采用玻璃钝化芯片结构,封装为 SMB(DO-214AA)。该器件为单向工作型,设计用于在瞬态过电压事件(如雷击、电源浪涌、开关瞬变等)发生时对电子设备提供可靠的钳位与吸能保护。

二、主要电气参数

  • 类型:TVS(瞬态电压抑制器)
  • 极性:单向
  • 反向工作电压 Vrwm:36 V
  • 击穿电压 VBR(在指定电流下):40 V
  • 钳位电压(Ipp 条件下):58.1 V
  • 峰值脉冲电流 Ipp:10.33 A(10/1000 μs 波形)
  • 峰值脉冲功率 Ppp:600 W(10/1000 μs,重复率/占空比 0.01%)
  • 反向漏电流 Ir:1 μA(典型/最大值视测试条件)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SMB(DO-214AA)
  • 标准:符合 RoHS

三、结构与性能特点

  • 玻璃钝化芯片:提高器件的长期可靠性、热稳定性与漏电流控制。
  • 高峰值吸收能力:600 W(10/1000 μs)能有效应对工业级浪涌与雷击脉冲。
  • 低泄漏电流:在工作电压附近保持极低漏电,有利于节能与敏感电路的可靠运行。
  • 快速响应:瞬态来临时能在纳秒级启动钳位,抑制过电压对下游器件的损害。
  • 单/双向可选:本型号为单向(SMBJ36A),系列中亦有双向器件以满足交流或双向保护需求。
  • RoHS 合规:满足环保与无铅制造要求。

四、典型应用场景

  • 开关电源输出与输入保护(DC 36 V 左右系统)
  • 工业控制与自动化设备的电源/信号线防护
  • 通信设备与基站的接口保护
  • 电池管理、电动车充电桩等对瞬态浪涌有较高要求的场合
  • 工业以太网、RS-485 等差分/单端数据线的保护(视电路拓扑选择单/双向型号)

五、使用建议与注意事项

  • 极性识别:单向 TVS 在电路中需按极性正确安装,通常以标识端连接到受保护电路的地或负极。
  • 热管理:在频繁脉冲或高环境温度下,注意器件散热与PCB铜箔面积以防温升影响寿命。
  • 浪涌能力限制:标注的 600 W(10/1000 μs)与 10.33 A 为单次脉冲能力且基于 0.01% 占空比;连续或高频脉冲需采取更严格的降额或外加保护。
  • 焊接工艺:遵循厂家推荐的回流温度曲线和预热/冷却要求,以避免封装或内部结构损伤。
  • 储存与使用环境:避免潮湿、强腐蚀性气体环境,并防止超出器件最高结温(+150 ℃)的工作条件。

六、选型与替代

在选择 SMBJ36A 时,应核实系统的最大工作电压、允许钳位电压以及预期的浪涌能量。若系统为交流或需双向保护,可选用同系列的双向型号。必要时可参考同类封装(SMB)中不同额定电压的 TVS 器件以匹配更高或更低的系统电压。

如需器件数据手册(详细 V-I 曲线、钳位特性、热阻、封装尺寸和回流规范)或批量采购信息,请提供具体需求以便获取更详尽的资料。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
