SMAJ15CA TVS二极管产品概述

概要

SMAJ15CA 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)和瞬态浪涌电流的损害。以下是对该产品的详细介绍。

基础参数

  • 击穿电压(Vc): 16.7V
    • 这是指在正常工作条件下,TVS二极管开始进行电流调节并将输入电压钳制在安全水平上的电压。
  • 反向截止电压(Vrwm): 15V
    • 这是指在反向偏置条件下,TVS二极管可以承受的最大持续电压。
  • 反向漏电流(Ir): 1uA
    • 在指定的反向截止电压下,通过TVS二极管的微小电流。
  • 峰值脉冲电流(Ipp): 16.4A
    • 这是指TVS二极管在短时间内(通常为8/20μs)可以承受的最大峰值电流。
  • 最大钳位电压(Vcl): 24.4V
    • 当TVS二极管工作在峰值脉冲电流条件下时,能够钳制的最大输出电压。

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静电放电和瞬态浪涌电流的影响,确保设备的可靠性和长寿命。

封装类型

  • SMA(DO-214AC)
    • SMA封装是一种小型的表面安装封装,适用于空间有限的应用场景。DO-214AC是SMA封装的具体类型,具有高可靠性和良好的热性能。

应用场景

SMAJ15CA TVS二极管广泛应用于各种需要保护电子设备免受静电和浪涌影响的场景,包括:

  • 通信设备: 手机、无线路由器、调制解调器等。
  • 工业控制系统: PLC、传感器、执行器等。
  • 汽车电子: 汽车电子控制单元(ECU)、传感器系统等。
  • 消费电子: 电视机、音响设备、家用电器等。
  • 医疗设备: 医疗监护仪、手术设备、诊断设备等。

工作原理

TVS二极管通过其独特的结构来实现保护功能。当输入电压超过反向截止电压时,TVS二极管会迅速导通,将过高的电压钳制在安全水平上,从而保护后级电子设备。这种快速响应和高效的保护机制使得TVS二极管成为现代电子系统中的必备组件。

优势

  • 高峰值脉冲电流承受能力: SMAJ15CA能够承受高达16.4A的峰值脉冲电流,确保在极端条件下也能提供可靠的保护。
  • 低反向漏电流: 仅1uA的反向漏电流意味着在正常工作状态下,TVS二极管对系统的能耗影响极小。
  • 小型化封装: SMA封装使得该设备适用于空间有限的应用场景,同时也提高了安装效率和可靠性。
  • 广泛兼容性: 适用于多种类型的电子设备和系统,提供通用且可靠的保护解决方案。

安装注意事项

在安装SMAJ15CA TVS二极管时,需要注意以下几点:

  • 确保正确的极性连接,以避免反向偏置导致的损坏。
  • 避免在安装过程中产生静电,以防止对设备造成损害。
  • 遵循推荐的焊接参数,以确保良好的接触和可靠性。

总结

SMAJ15CA TVS二极管是由晶导微电子生产的一款高性能静电和浪涌保护设备。其优异的参数和小型化封装使其成为广泛应用于各种电子系统中的理想选择。通过其高效的保护机制和低能耗特性,SMAJ15CA能够确保电子设备在复杂环境中的可靠运行和长寿命。

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
