AQ24C-01FTG 汽车级双向TVS ESD抑制器产品概述

AQ24C-01FTG是美国力特(Littelfuse)针对车载电子系统推出的汽车级双向瞬态电压抑制器(TVS),核心用于防护静电放电(ESD)与瞬态浪涌对敏感元件的损害,符合AEC-Q101可靠性标准,具备小尺寸、高防护能力的特点,适配车载低压电路的严苛应用场景。

一、产品定位与核心特性

AQ24C-01FTG定位于车载低电压电路的综合防护,核心特性包括:

  1. 双向防护无极性:无需区分正负极,简化电路设计,适配正负瞬态过压场景;
  2. 汽车级可靠性:通过AEC-Q101认证,满足车载环境的温度、振动、湿度等严苛要求;
  3. 小尺寸高密度:采用SOD-323贴片封装,尺寸仅1.6mm×0.8mm,适合车载高密度PCB布局;
  4. 宽标准覆盖:兼容IEC 61000-4-2(ESD)、IEC 61000-4-5(浪涌)等国际防护标准,兼顾静电与浪涌防护。

二、关键电气参数详解

参数针对车载12V/24V低压电路优化,核心指标如下:

  • 反向截止电压(Vrwm):24V,匹配车载系统常态工作电压范围,常态下不导通;
  • 击穿电压(Vbr):26.7V(典型值),瞬态过压触发时快速导通,抑制电压上升;
  • 钳位电压(Vc):42V(@Ipp=7A),当遭遇8/20μs波形浪涌时,将过压钳位至42V以内,保护后级元件;
  • 峰值脉冲电流(Ipp):7A(8/20μs波形),可承受单次高能量浪涌冲击;
  • 峰值脉冲功率(Ppp):450W,对应浪涌能量耐受能力;
  • 反向漏电流(Ir):1μA(@Vrwm=24V),常态漏电流极小,不影响电路正常工作。

三、封装与可靠性设计

  1. SOD-323封装细节:
    • 尺寸:1.6mm(长)×0.8mm(宽)×0.6mm(高),无铅环保(RoHS/REACH compliant);
    • 工艺兼容性:适配回流焊、波峰焊等标准贴片工艺,适合车载自动化生产;
  2. 汽车级可靠性保障:
    • 温度范围:-55℃~+150℃,覆盖车载极端环境(发动机舱、冬季低温区域);
    • 抗振动性能:符合AEC-Q101振动测试要求,可承受车载行驶中的机械振动;
    • 长期稳定性:低漏电流设计减少老化风险,匹配车载10年以上生命周期。

四、应用场景与合规性

  1. 典型车载应用:
    • 传感器接口:摄像头、雷达、胎压监测(TPMS)传感器的信号端口;
    • ECU接口:车身控制器、动力系统ECU的输入/输出端口;
    • 通讯总线:CAN/LIN总线收发器的防护;
    • 显示系统:中控屏、仪表盘的触摸/显示接口;
  2. 合规性认证:
    • 防护标准:IEC 61000-4-2(ESD:接触±8kV、空气±15kV)、IEC 61000-4-5(浪涌:±2kV/±1kA);
    • 汽车标准:AEC-Q101(汽车电子元器件可靠性);
    • 环保标准:RoHS(无铅)、REACH(无有害物质)。

五、典型应用方案参考

以车载TPMS传感器接口防护为例:

  • 电路拓扑:AQ24C-01FTG并联于TPMS传感器信号输出端与地之间;
  • 防护逻辑:当遭遇静电(人体接触)或电源浪涌时,TVS快速导通,将过压钳位至42V以内,避免传感器MCU、射频芯片击穿;
  • 优势:小尺寸不占用传感器PCB空间,双向防护简化设计,汽车级可靠性匹配车载环境。

AQ24C-01FTG凭借双向防护、汽车级可靠性与小尺寸封装,成为车载低电压电路ESD/浪涌防护的理想选择,可有效提升车载电子系统的抗干扰能力与长期稳定性。

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
