SMBJ28CA(YANGJIE 扬杰)产品概述

一、产品简介

SMBJ28CA 是扬杰(YANGJIE)出品的一款双向瞬态电压抑制二极管(TVS),封装为 SMB(DO-214AA)。器件面向 24V/28V 直流电源总线及信号线的浪涌保护设计,能在电源和信号回路遭受雷击、开关瞬变或电磁干扰时,迅速钳制过电压,保护下游敏感器件和电路板。

二、主要特点

  • 双向抑制,适用于交流或可双向承受脉冲的线路保护
  • 反向截止电压 Vrwm = 28V,适配 24V 及类似等级电源系统
  • 钳位电压典型值 Vc = 45.4V(在指定脉冲条件下)
  • 峰值脉冲电流 Ipp = 13.2A(10/1000µs 波形)
  • 峰值脉冲功率 Ppp = 600W(10/1000µs)
  • 击穿电压 Vbr ≈ 34.4V,低漏电流 Ir = 5µA(常温下)
  • 工作温度范围宽:-55℃ 至 +150℃,SMB 封装便于自动贴装与散热

三、典型电气参数

  • 反向工作电压(Vrwm):28V
  • 击穿电压(Vbr):34.4V
  • 钳位电压(Vc)典型:45.4V(Ipp 条件)
  • 峰值脉冲电流(Ipp, 10/1000µs):13.2A
  • 峰值脉冲功率(Ppp, 10/1000µs):600W
  • 反向漏电流(Ir):5µA
  • 工作温度:-55℃ 至 +150℃

四、典型应用场景

  • 24V 工业电源总线、PLC、驱动器的浪涌保护
  • 通信设备、电源适配器输入端防护
  • 传感器节点、控制信号线和继电器驱动回路的瞬态抑制
  • 电力设备、楼宇自控、测试测量设备的浪涌防护

五、选型与使用建议

  • 放置位置:将器件尽量靠近外部接口或可能的浪涌入口,减小引线与走线长度以降低串联感抗。
  • 接地要求:为保证有效能量传导,保护器的负极/接地应有低阻抗连接到系统地。
  • 功率与能量:Ppp 与 Ipp 基于 10/1000µs 波形,实际应用时需评估可能的脉冲能量,必要时采用并联或配合限流器件(如熔断器、电阻)来扩展能量处理能力。
  • 热管理:在高频次冲击或高环境温度下,器件容许的冲击能量会下降,应留有余量并避免长期在 Vrwm 上持续承载大电流。
  • 极性:本器件为双向,适合交流/反向脉冲场合,安装时无需区分正负极,但仍按封装方向与PCB布局规范焊接。

六、封装与安装注意

  • 封装类型:SMB(DO-214AA),适合自动贴装、波峰/回流焊工艺。
  • PCB 布局:在焊盘周围留有足够铜箔以提高散热,必要时使用过孔与底层大铜面连接以增强散热与接地。
  • 焊接工艺:请参考厂商推荐的回流/波峰焊工艺参数进行处理,避免超温或过快冷却导致封装应力。

七、使用限制与安全提示

  • TVS 旨在承受短时脉冲能量,不可作为连续电压稳压器长期工作。
  • 在高温下漏电流会增加,且脉冲承受能力下降,设计时需考虑温度对性能的影响。
  • 对于关键安全应用,建议进行实电路冲击测试以验证保护效果,并遵守相关行业标准与认证要求。

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
