KSD05T1G 单路单向瞬态抑制二极管(TVS)产品概述

一、产品概述
KSD05T1G 是 KUU 品牌的一款单路、单向瞬态电压抑制(ESD/TVS)器件,采用紧凑的 SOD-323 封装,专为在空间受限电路板上对敏感线路提供瞬态过压保护而设计。器件在对抗静电放电(ESD)、电缆放电事件(CDE)和电快速瞬变(EFT)方面表现优异,适合保护电源线、数据线和传输线路上的易损器件。

二、主要参数(典型/最大值)

  • 极性:单向
  • 反向截止电压 Vrwm:5 V
  • 击穿电压 VBR:6 V
  • 钳位电压:18 V(在典型脉冲条件下)
  • 峰值脉冲电流 Ipp:17 A
  • 峰值脉冲功率 Ppp:350 W(典型 10/1000 μs 或规格给定脉冲)
  • 反向电流 Ir:10 μA
  • 结电容 Cj:10 pF(适合大多数高速信号)
  • 通道数:单路
  • 工作温度:-55 ℃ 至 +150 ℃
  • 防护等级/符合标准:IEC 61000-4-2(ESD)与 IEC 61000-4-4(EFT)
  • 封装:SOD-323

三、产品特点与优势

  • 小尺寸封装:SOD-323 适合空间受限的消费电子与工业板级保护。
  • 低结电容(10 pF):对高速数据线影响小,可用于 USB、串口等敏感信号路径。
  • 高峰值吸收能力:17 A 峰值脉冲电流与 350 W 峰值功率可有效吸收短时高能瞬态。
  • 宽工作温度范围:适应严苛工业与医疗等环境。
  • 钳位性能良好:在瞬态时将被保护节点钳位到约 18 V,限制过电压对下游器件的损伤。
  • 符合 IEC 抗扰标准:便于通过系统级电磁兼容(EMC)设计与认证。

四、典型应用场景

  • 个人电脑外设、打印机与商用设备的输入/输出保护;
  • 通信设备与网络接口的防护;
  • 医疗仪器敏感信号线与控制线的瞬态保护;
  • 电源线、信号传输线和接口(如低压供电、UART、I2C、低速差分线等)保护;
  • 任意需在有限 PCB 空间内实现稳健 ESD/EFT 抗扰的场景。

五、PCB 布局与使用建议

  • 靠近待保护的连接器或器件放置 TVS,以最小化走线电感和寄生电阻;
  • TVS 的地引脚应尽可能短、直且通过地平面回流,以便快速将能量导入地;
  • 对高速信号通道,需权衡结电容(10 pF)对信号完整性的影响,必要时在原型验证中测量眼图或信号延迟;
  • 对于双向或更高电压系统,应确认单向型 TVS 的极性与系统工作电压匹配(Vrwm = 5 V 指常态可承受约 5 V 直流反向电压)。

六、选型与注意事项

  • 确认系统工作电压与 Vrwm(5 V)匹配,若系统常态电压高于 Vrwm,应选择更高 Vrwm 的型号;
  • 钳位电压(18 V)为瞬态下的典型值,需评估下游器件在此电压下的承受能力;
  • 若保护高速差分对或更低容性要求线路,比较 Cj 值并在必要时选择更低电容器件;
  • 在高能脉冲或重复冲击环境(如车辆电气)下,评估长期可靠性或考虑更高功率等级的保护器件。

KSD05T1G 因其小型化封装、合适的钳位与吸收能力及对 IEC 标准的适配,非常适合在消费电子、通信与医疗等需要板级瞬态保护且空间受限的应用中使用。如需针对具体系统(如 USB、以太网或电源总线)做进一步的电气匹配与布局优化建议,可提供系统工作条件与连接拓扑以便给出更具体的方案。

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
