SMAJ12CA TVS二极管产品概述

概要

SMAJ12CA 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)和瞬时浪涌电流的损害。以下是对此产品的详细介绍。

基础参数

  • 击穿电压(Vc): 13.3V
    • 击穿电压是指在正常工作条件下,TVS二极管开始导通并吸收过载能量的电压阈值。
  • 反向截止电压(Vrwm): 12V
    • 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): 1uA
    • 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): 20.1A
    • 表示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: 19.9V
    • 当TVS二极管导通时,能够限制的最大电压值,确保保护电路不受损害。

商品分类

  • 静电和浪涌保护(TVS/ESD)
    • 这类设备专门用于保护电子设备免受静电放电和瞬时浪涌电流的影响。

封装类型

  • SMA(DO-214AC)
    • SMA封装是一种小型、表面安装封装,适合于空间有限的应用场景。DO-214AC是SMA封装的标准名称。

应用场景

静电保护

SMAJ12CA广泛应用于需要防护静电放电的电子设备中。静电放电可能导致敏感电子元件受损或功能失常。通过安装SMAJ12CA,能够有效地吸收和分散静电能量,从而保护下游电路。

####浪涌保护 在许多工业和商业应用中,设备可能会遇到各种形式的浪涌电流,如雷击、电源切换等。SMAJ12CA能够在这些情况下迅速响应并将过载电流导向地线,防止设备受损。

技术特点

高峰值脉冲电流承受能力

SMAJ12CA能够承受高达20.1A的峰值脉冲电流,这使得它特别适合于需要高级别保护的应用场景。

低反向漏电流

仅1uA的反向漏电流确保了在正常工作状态下,TVS二极管对电路的影响最小化,不会显著增加系统的功耗或噪声。

小型化封装

采用SMA(DO-214AC)封装,使得SMAJ12CA非常适合于空间有限的设计,能够轻松集成到各种现代电子产品中。

安装和使用注意事项

安装位置

应将SMAJ12CA安装在需要保护的敏感电路与可能引入过载能量的接口之间。例如,在接口端口、电源输入端等位置。

####极性标识 由于TVS二极管具有极性,必须确保正确安装极性,以避免设备损坏或保护功能失效。

####热设计考虑 在高功率应用中,需要考虑TVS二极管的热设计,以确保其在长时间运行中不会过热影响性能。

总结

SMAJ12CA TVS二极管是晶导微电子的一款高性能静电和浪涌保护设备,通过其卓越的技术参数和小型化封装,广泛应用于各种需要高可靠性和高保护水平的电子系统中。其高峰值脉冲电流承受能力、低反向漏电流以及小型化设计,使其成为现代电子工程师的理想选择。通过正确安装和使用SMAJ12CA,可以显著提高电子设备的可靠性和耐用性。

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
