SMBJ36CA(36V)双向TVS二极管 产品概述

一、产品简介

SMBJ36CA 是 MDD 提供的一款 SMB(DO-214AA) 封装的双向瞬态电压抑制器(TVS)。该器件专为抑制电源线和信号线上的瞬态过电压而设计,具有高峰值脉冲能力、低漏电流与宽工作温度范围,适用于工业、电信、汽车电子等需要抗浪涌与电磁脉冲保护的场合。

二、主要参数

  • 钳位电压(Vc):58.1 V
  • 工作温度:-65 ℃ ~ +150 ℃
  • 击穿电压(Vbr):44.2 V
  • 反向截止电压 Vrwm:36 V
  • 峰值脉冲功率 Ppp:600 W @ 10/1000 µs
  • 峰值脉冲电流 Ipp:10.4 A @ 10/1000 µs
  • 反向电流 Ir:1 µA(常温)
  • 极性:双向
  • 封装:SMB (DO-214AA)
    这些参数体现了器件在浪涌事件中将能把尖峰能量钳位到安全电平,保护后端电路免受瞬态破坏。

三、电气特性与工程意义

  • Vrwm = 36 V 表示在正常工作状态下,器件对直流或反向电压有较高的耐受性,适合 24 V~36 V 等中高压工况。
  • Vbr = 44.2 V 为器件开始导通的击穿电压区间,超过该电压后进入导通态并将电压钳制到 Vc。
  • Vc = 58.1 V 是在指定脉冲条件下的钳位电压,工程上需保证被保护电路在该电压下不会损坏。
  • Ppp=600 W 与 Ipp=10.4 A(10/1000 µs)表明其对长时间下降沿浪涌(如雷击后残波)具备很好的能量吸收能力。

四、封装与热管理

SMB/DO-214AA 封装便于自动化贴装与焊接,具有良好机械强度。由于脉冲能量会引起结温上升,建议在 PCB 设计中提供合适的铜箔散热区域和热沉路径,尤其在可能承受重复浪涌的应用中应考虑热疲劳和热循环影响。

五、典型应用

  • 电源线浪涌保护(AC/DC输入、DC总线)
  • 通信设备与基站接口保护
  • 工业控制系统与传感器节点的防雷/浪涌保护
  • 汽车电子(需按车规认证选择)
    双向特性适合存在正负双向脉冲或交流耦合的线路。

六、使用与 PCB 布局建议

  • 将 TVS 尽量靠近需要保护的接口或受保护点布置,以缩短串联电感路径。
  • 使用宽铜箔连接器件两端到地或电源轨,减小阻抗并提高散热。
  • 对于高能量条件,增加熔断器或限流器以避免过载长期影响 TVS。
  • 在多次冲击场景下,定期评估器件是否发生性能退化或机械损伤。

七、可靠性与存储

工作温度范围 -65 ℃ ~ +150 ℃ 适应宽温环境。存储与焊接时遵循湿敏等级与回流温度规范,避免超高温或潮湿导致结晶缺陷。长期在高温或高漏电环境下应考虑老化影响。

八、采购与替代

型号:SMBJ36CA,品牌:MDD,封装:SMB(DO-214AA)。在选型时可参考其它厂商同类 36 V 双向 SMBJ 系列作为替代,但需核对 Vrwm、Vbr、Vc、Ppp、Ipp 与封装兼容性以确保互换性。购买时建议索取样品并进行实际浪涌测试验证。

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
