SMAJ30CA 产品概述

概要

SMAJ30CA 是由台湾君耀(Brightking)公司生产的一款静电和浪涌保护(TVS/ESD)二极管,专门设计用于保护电子设备免受静电放电(ESD)和瞬态浪涌电流的损害。以下是对此产品的详细介绍。

基础参数

  • 击穿电压(Vc): 33.3V
    • 这是指在正常工作条件下,TVS 二极管开始进行电流调节和保护的电压阈值。
  • 反向截止电压(Vrwm): 30V
    • 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。
  • 反向漏电流(Ir): 1 μA
    • 在指定的反向截止电压下,通过 TVS 二极管的微小漏电流。
  • 峰值脉冲电流(Ipp): 8.3 A
    • 表示 TVS 二极管在短时间内(通常为几微秒)可以承受的最大峰值电流。
  • 最大钳位电压(Vcl): 48.4 V
    • 当TVS二极管工作时,能够限制的最大输出电压,确保下游设备不会受到过高电压的损害。

类型和封装

  • 类型: TVS(Transient Voltage Suppressor)
    • 用于保护电子设备免受瞬态电压冲击和静电放电的影响。
  • 封装: DO-214AC (SMA)
    • 小型封装,适合于空间有限的应用场景,提供高密度安装。

商品分类

  • 静电和浪涌保护(TVS/ESD)
    • 专门用于防护静电放电和瞬态浪涌电流,这些都可能对电子设备造成严重损害。

描述

SMAJ30CA 是一款双向 TVS 二极管,这意味着它可以在正向和反向两种偏置状态下提供保护。这种双向特性使其适用于需要在两种极性下都提供保护的应用场景。

应用场景

电子设备保护

SMAJ30CA 广泛应用于各种电子设备中,以防护这些设备免受静电放电或瞬态浪涌电流的影响。例如,在通信设备、计算机系统、汽车电子系统以及工业控制系统中,都可以看到其应用。

接口保护

在数据接口、通信端口等地方,SMAJ30CA 可以有效地防止由于外界环境变化或操作不当导致的静电放电对设备的损害。

电源系统保护

在电源系统中,尤其是那些需要高可靠性的应用场景中,SMAJ30CA 可以作为过压保护元件,确保系统在意外情况下不会受到损害。

优势

高效过压保护

SMAJ30CA 具有快速响应时间和高峰值脉冲电流承受能力,能够迅速响应并消除过压脉冲,保护下游设备。

小型化封装

DO-214AC (SMA) 封装使得该元件非常适合于空间有限的应用场景,提高了系统的整体设计灵活性。

双向保护

作为一款双向 TVS 二极管,SMAJ30CA 可以在正向和反向两种偏置状态下提供保护,这大大扩展了其应用范围。

安装和使用注意事项

安装位置

应将 SMAJ30CA 安装在需要保护的敏感设备附近,以确保其能够及时响应并消除过压脉冲。

电路设计

在设计电路时,应确保 TVS 二极管的工作条件符合其规格参数,避免因过载或误用而导致元件损坏。

焊接要求

由于 DO-214AC 封装较小,焊接过程需要谨慎进行,以避免因热应力或焊接不良导致的元件故障。

总结

SMAJ30CA 是一款功能强大、体积小巧的静电和浪涌保护 TVS 二极管,适用于广泛的电子设备保护应用。其高效过压保护能力、双向工作特性以及小型化封装,使其成为许多设计工程师的首选元件。通过正确安装和使用,SMAJ30CA 可以有效地保护您的电子设备免受意外电压变化的影响。

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
