SMBJ26CA TVS二极管产品概述

概要

SMBJ26CA 是一种由晶导微电子生产的静电和浪涌保护(TVS/ESD)二极管,专门设计用于保护电子设备免受静电放电(ESD)和瞬态电压浪涌(TVS)的影响。以下是对此产品的详细介绍。

基础参数

  • 击穿电压(Vc): 28.9V
    • 这是指在正常工作条件下,TVS二极管开始进行电流导通并吸收过电压能量的阈值电压。
  • 反向截止电压(Vrwm): 26V
    • 这是指在反向偏置状态下,TVS二极管可以承受的最大持续电压。
  • 峰值脉冲电流(Ipp): 14.3A
    • 表示TVS二极管在短时间内(通常为10/1000μs)可以承受的最大电流峰值。
  • 最大钳位电压(Vcl): 42.1V
    • 当TVS二极管工作在保护模式时,能够限制输出端口的最大电压。

商品分类

  • 静电和浪涌保护(TVS/ESD)
    • 这类设备旨在保护电子设备免受由于静电放电或瞬态电压浪涌引起的损害。

类型

  • TVS(Transient Voltage Suppressor)
    • TVS二极管是一种专门用于吸收和分散瞬态过电压能量的器件,确保下游设备的安全运行。

封装

  • SMB(DO-214AA)
    • SMB封装是一种小型、表面安装封装,适用于空间有限的应用场景。DO-214AA是SMB封装的具体类型,具有良好的热性能和机械强度。

应用场景

电子设备保护

SMBJ26CA广泛应用于各种电子设备中,以保护这些设备免受静电放电和瞬态电压浪涌的影响。例如,在通信设备、计算机系统、工业控制系统以及汽车电子等领域,都可以看到其应用。

接口保护

在数据传输接口(如USB、RS-232等)中,SMBJ26CA可以防止由于外部环境变化或意外事件引起的过电压对设备造成损害。

电源输入保护

在电源输入端,SMBJ26CA可以有效地吸收由于雷击、电网闪变等原因产生的瞬态过电压,从而保护电源模块和后续电路。

工作原理

当输入端出现过电压时,TVS二极管会迅速导通,将过电压能量分散并限制输出端口的电压在安全范围内。这一过程发生在非常短的时间内(通常为几纳秒),确保下游设备不会受到损害。

优势

高效保护

  • SMBJ26CA具有高峰值脉冲电流能力(14.3A),能够有效地处理大幅度的过电压事件。
  • 低反向截止电压(26V)和高击穿电压(28.9V)使其在正常工作状态下不会干扰系统,而在需要保护时迅速响应。

小型化设计

  • 采用SMB(DO-214AA)封装,使得SMBJ26CA非常适合于空间有限的应用场景,简化了PCB设计和布局。

可靠性高

  • 晶导微电子的严格质量控制和测试过程保证了SMBJ26CA的可靠性和稳定性,适用于要求高可靠性的应用环境。

使用注意事项

安装方向

  • 确保正确安装TVS二极管的极性,以避免反向偏置导致的损坏。

热设计

  • 考虑到TVS二极管在工作时可能产生热量,需要确保良好的散热设计以延长其使用寿命。

并联使用

  • 根据具体应用需求,可以考虑将多个TVS二极管并联使用,以提高总体保护能力。

总结

SMBJ26CA TVS二极管是保护电子设备免受静电放电和瞬态电压浪涌影响的一种高效、可靠的解决方案。其优异的性能参数、紧凑的封装以及广泛的应用场景,使其成为许多工程师和设计师的首选器件。如果您需要为您的电子产品提供强大的过电压保护功能,SMBJ26CA绝对是一个值得考虑的选择。

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
