SD24C-01FTG 产品概述

一、产品简介

SD24C-01FTG 是 DOWO(东沃)推出的一款单路瞬态抑制二极管(TVS),用于保护电子设备的信号线和电源线免受静电放电(ESD)与浪涌(Surge)冲击。器件封装为小型 SOD-323,适合高密度表贴PCB设计,工作温度范围为 -55℃ 到 +125℃,可在严苛环境下稳定工作。描述字段为“未分类”,定位为通用型防护元件。

二、主要电气参数

  • 反向截止电压 Vrwm:24 V(工作保护电压)
  • 击穿电压 Vbr(典型):26.7 V
  • 钳位电压 Vclamp(浪涌或脉冲钳位):50 V
  • 峰值脉冲电流 Ipp:8 A(8/20 µs 波形)
  • 峰值脉冲功率 Ppp:420 W @ 8/20 µs
  • 反向漏电流 Ir:1 µA(常温条件下)
  • 结电容 Cj:30 pF(对高速信号影响需注意)
  • 通道数:单路
  • 防护等级/标准:满足 IEC 61000-4-5(浪涌)和 IEC 61000-4-2(静电放电)规范

三、产品特性与优势

  • 高能量吸收:420 W @ 8/20 µs 的峰值功率和 8 A 峰值脉冲电流,能够有效吸收工业级浪涌能量。
  • 低钳位电压:50 V 的钳位电压在突发过压时能将被保护节点电压限制在安全范围内,降低后端电路损伤风险。
  • 低漏电流:1 µA 的反向电流对电源供给和高阻输入的电路影响小,有利于低功耗应用。
  • 小封装:SOD-323 占板面积小,适合空间受限或多路保护的场景。
  • 宽温度范围:-55℃~+125℃,适合工业与汽车周边环境(请结合具体车规要求核实)。

四、典型应用场景

  • USB、UART、RS-485 等通信接口的端口保护
  • 工业控制器、PLC 的外部信号线防护
  • 电源输入防护(24 V 系统旁路保护)
  • 消费电子和仪器仪表的面板按键与接口防护
  • 办公设备、POS、安防设备的接地与信号保护

五、选型与使用建议

  • 若保护对象为高速差分信号(如 USB3.0、高速以太网),需评估 30 pF 结电容对信号完整性的影响,可能需选择低容型 TVS;对于低速或数字控制线,30 pF 在多数情况下可接受。
  • 使用时应将 TVS 近距离并行焊接到受保护引脚与地之间,以缩短回路面积,提升防护效果。
  • 注意钳位电压与后端组件耐压匹配:50 V 钳位电压下,后端器件需能承受瞬态电压或在钳位前加一级限压。
  • 长期应用在高温或强浪涌环境时,验证器件热耗散与PCB散热路径,必要时增加热铜或散热结构。

六、封装与可靠性

SOD-323 小封装利于密集布线,但对焊接工艺敏感,建议按通用无铅回流温度曲线进行焊接,避免长时间高温暴露。器件通过 IEC 61000-4-2 与 IEC 61000-4-5 等电磁兼容测试,可靠性满足工业级防护需求。

七、注意事项

  • 使用前请确认具体器件数据手册以获取完整的电气特性曲线和热极限参数。
  • 对于多通道或更高能量需求场合,可考虑并联或使用更高功率等级的 TVS 器件,但并联时需注意一致性和共享问题。
  • 在关键应用(如车规)中,需核查是否有相应的车规认证与长期可靠性测试报告。

总体而言,SD24C-01FTG 适用于需要中等能量吸收、24 V 工作电压等级下的单通道接口和电源保护场合,凭借小封装和良好的浪涌/ESD 抑制能力,可为多类电子设备提供经济高效的防护方案。

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
