SMAJ30CA TVS二极管产品概述

介绍

SMAJ30CA 是一种由晶导微电子生产的Transient Voltage Suppressor (TVS) 二极管,专门用于静电和浪涌保护(TVS/ESD)。这款元器件采用DO-214AC封装,设计用于保护电子设备免受瞬态电压和静电放电的损害。

基础参数

以下是SMAJ30CA TVS二极管的一些关键参数:

  • 击穿电压: 33.3V

    • 这是指在正常工作条件下,TVS二极管开始导通并吸收过电压能量的电压阈值。
  • 反向截止电压(Vrwm): 30V

    • 这是指TVS二极管在反向偏置状态下可以承受的最大持续电压,不会导致元器件损坏。
  • 峰值脉冲电流(Ipp): 8.3A

    • 这表示TVS二极管可以在短时间内(通常为几微秒)承受的最大电流峰值,用于处理高能量的瞬态事件。
  • 最大钳位电压: 48.4V

    • 当TVS二极管导通时,能够限制输出电压不超过此值,从而保护下游设备。

类型和封装

  • 类型: TVS (Transient Voltage Suppressor)

    • 作为一种专门用于瞬态电压保护的二极管,SMAJ30CA 能够快速响应并吸收过电压能量。
  • 封装: DO-214AC (SMA)

    • DO-214AC封装是一种小型、表面安装封装,适合于空间有限的现代电子设备设计。

应用场景

SMAJ30CA TVS二极管广泛应用于各种需要保护电子设备免受瞬态电压和静电放电影响的场景,包括但不限于:

  • 通信设备: 手机、无线路由器、调制解调器等通信设备需要保护其敏感电子元件免受雷击或静电损害。

  • 工业控制系统: 工业控制系统中的传感器、驱动器和控制器需要防护以确保在恶劣环境下可靠运行。

  • 汽车电子: 现代汽车中的电子系统,如ABS、EPS、娱乐系统等,都需要高可靠性的过电压保护。

  • 家用电器: 家用电器如电视机、空调、洗衣机等也需要保护其内部电子元件免受电源波动或静电的影响。

工作原理

SMAJ30CA TVS二极管通过以下方式来保护电子设备:

  1. 正常工作状态:

    • 在正常工作电压范围内,TVS二极管处于反向偏置状态,不会影响主电路的正常运行。
  2. 过电压事件:

    • 当输入电压超过设定的阈值(如反向截止电压Vrwm),TVS二极管迅速导通,将过电压能量吸收并将输出电压限制在安全范围内(最大钳位电压)。
  3. 峰值脉冲处理:

    • 在短时间内,TVS二极管可以承受高达8.3A的峰值脉冲电流,这确保了它能够处理高能量的瞬态事件。

优势

使用SMAJ30CA TVS二极管具有以下优势:

  • 高效保护: 快速响应和高效吸收过电压能量,确保下游设备的安全。

  • 小型化设计: DO-214AC封装使其适合于现代电子设备的紧凑设计要求。

  • 高可靠性: 经过严格测试和验证,确保在各种环境条件下提供可靠的保护性能。

总结

SMAJ30CA TVS二极管是由晶导微电子生产的一款高性能、可靠性强的静电和浪涌保护元器件。其优异的参数和小型化设计使其成为广泛应用于通信设备、工业控制系统、汽车电子以及家用电器等领域的理想选择。通过其快速响应和高效保护能力,SMAJ30CA 有助于提高电子设备的整体可靠性和耐用性。

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
