SMAJ6.8CA 产品概述

概要

SMAJ6.8CA 是由友台半导体(UMW)生产的一款双向Transient Voltage Suppressor(TVS)元器件,专门用于静电和浪涌保护(TVS/ESD)。这款元器件以其高效的过压保护能力和紧凑的封装设计,广泛应用于各种电子设备中,确保系统在面临意外的电压峰值时能够保持稳定运行。

基础参数

  • 击穿电压(Vc): 6.45V
    • 这是指在特定条件下,TVS 开始导通并吸收过压能量的电压阈值。
  • 反向截止电压(Vrwm): 5.8V
    • 这是指TVS在正常工作状态下可以承受的最大反向电压,超过此值会导致TVS开始导通。
  • 反向漏电流(Ir): 1mA
    • 在反向截止电压下,TVS允许的最大漏电流。
  • 峰值脉冲功率(Ppp): 400W
    • 表示TVS可以在短时间内吸收和分散的最大能量。
  • 峰值脉冲电流(Ipp): 38.1A
    • 指在短时间内TVS可以承受的最大电流峰值。
  • 最大钳位电压: 10.5V
    • 当TVS导通后,限制输出电压的最大值。

类型和封装

  • 类型: TVS(Transient Voltage Suppressor)
    • 专门设计用于保护电子设备免受瞬态过压的影响。
  • 封装: 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。

应用场景

SMAJ6.8CA 双向TVS 适用于各种需要过压保护的电子系统,包括但不限于:

  • 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、驱动器等。
  • 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、手术设备等。

特点和优势

  1. 高效过压保护
    • SMAJ6.8CA 具有快速响应时间和高峰值脉冲功率(400W),能够有效地保护电子设备免受瞬态过压的损害。
  2. 双向保护
    • 由于其双向结构,SMAJ6.8CA 可以在正向和反向电压下都提供保护,这使得它特别适合于那些需要双向保护的应用场景。
  3. 紧凑封装
    • 采用SMA(DO-214AC)封装,非常适合于空间有限的设计,提高了PCB布局的灵活性。
  4. 低漏电流
    • 在正常工作状态下,反向漏电流仅为1mA,这意味着在没有过压情况下,TVS对系统的影响非常小。

使用注意事项

  1. 安装方向
    • 确保TVS的极性正确安装,以避免反向偏置导致的损坏。
  2. 热设计
    • 考虑到TVS在吸收过压能量时可能产生的热量,确保PCB设计有足够的散热路径。
  3. 电路布局
    • 尽量将TVS放置在需要保护的敏感组件附近,以减少传导路径中的电感和电容,提高保护效果。

总结

SMAJ6.8CA 是一款功能强大、体积紧凑的双向TVS元器件,通过其出色的过压保护能力和低漏电流特性,广泛应用于各类电子设备中。其高峰值脉冲功率和电流能力使其成为保护电子系统免受静电和浪涌影响的理想选择。通过正确的安装和设计,这款TVS可以显著提高系统的可靠性和稳定性。

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
