SMBJ5.0CA — TVS瞬态抑制二极管产品概述

一、产品简介

SMBJ5.0CA 为 MDD 出品的双向瞬态电压抑制(TVS)二极管,封装为 SMB(DO-214AA)。器件专为保护 5V 直流电源和信号线免受雷击、浪涌及静电放电等瞬态过压而设计,响应速度快、吸收能量大,适用于工业、通信、消费类及汽车电子等对瞬态保护要求高的场合。

二、主要技术参数

  • 钳位电压(Vc):9.2V(典型)
  • 反向稳压/工作电压(Vrwm):5V
  • 击穿电压(Vbr):7V
  • 峰值脉冲功率(Ppp):600W(10/1000µs 波形)
  • 峰值脉冲电流(Ipp):65.3A(10/1000µs)
  • 反向漏电流(Ir):800µA(在 Vrwm 条件)
  • 极性:双向(Bi-directional)
  • 工作温度:-65℃~+150℃
  • 封装:SMB(DO-214AA)
  • 类型:TVS

三、特性与优势

  • 双向结构:可对正负极性瞬态进行对称抑制,免去极性选择问题,适合交流或双向脉冲环境。
  • 高脉冲吸收能力:10/1000µs 波形下 600W 峰值功率与 65.3A 峰值电流,能承受较强浪涌冲击。
  • 宽温度范围:-65℃ 至 +150℃,适应严苛环境与高温工作场景。
  • 小封装、大功率:SMB 封装便于 PCB 安装,同时兼顾散热与功率处理能力。

四、典型应用

  • 5V 电源总线保护(USB、通信模块、供电母线)
  • I/O 端口、接口保护(UART、CAN 等)
  • 工业控制与测量设备的浪涌防护
  • 汽车电子系统中对瞬态过压的一级防护(需结合系统可靠性要求评估)

五、封装与安装

SMB(DO-214AA)表面贴装,推荐焊盘设计遵循厂方 PCB 推荐图样以保证热量散发与机械强度。双向器件在安装时不区分极性,便于装配。

六、注意事项与可靠性

  • 反向漏电 Ir 为 800µA,为防止长期功耗增大,应结合系统待机电流需求评估。
  • 尽量避免在超出额定脉冲能量或频繁脉冲条件下使用,以免降低寿命。
  • 高温环境下应注意散热与周边元件布局,保证器件在额定温度下稳定工作。
  • 若用于汽车或关键可靠性场景,建议进行系统级测试验证并参考相关认证标准。

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
