SD05.TCT 产品概述
一、产品简介
SD05.TCT 是友台半导体（UMW）推出的一款单向瞬态抑制二极管（TVS），采用 SOD-323 封装，专为 5V 等低压电源与信号线提供高效的浪涌与静电防护。器件在 8/20µs 波形下可承受高达 360W 的峰值脉冲能量（Ppp），并具有低钳位电压与小体积的优点，适合在空间受限且需可靠防护的电路中使用。
二、主要参数
- 类型：单向 TVS 二极管
- 最大反向工作电压（Vrwm）：5V
- 击穿电压 VBR(Min)：6V
- 钳位电压（VC）：19V（典型条件下）
- 峰值脉冲电流（Ipp）：20A @ 8/20µs
- 峰值脉冲功率（Ppp）：360W @ 8/20µs
- 结电容（Cj）：120pF
- 反向漏电流（Ir）：1µA（Vrwm 条件下）
- 防护等级/符合标准：IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5
- 封装：SOD-323（小体积、表贴）
三、性能特点
- 强抗浪涌能力：360W/8/20µs 能量吸收能力，能有效钳位和吸收工业级浪涌与雷击感应脉冲。
- 低钳位电压：典型 19V 钳位，有利于保护后端元件免受高压冲击。
- 低漏电流：1µA 的反向漏电保证在待机或低功耗系统中不会引入明显额外损耗。
- 空间节省：SOD-323 小封装便于在紧凑布局中实现防护。
- 抗ESD/脉冲合规：通过 IEC 标准认证，适用于对静电与快速脉冲有要求的场合。
四、典型应用场景
- 5V 电源轨保护（USB、充电电路、主控供电）
- 工业控制、PLC 输入/输出端口防护
- 通信接口保护（低速数据线、串口、CAN 等）
- 仪器设备与消费类电子的入门防护元件
五、设计与布局建议
- 尽量靠近被保护的接口或芯片放置，减少引线电感与走线长度以提升抑制效率。
- 对于高速差分信号线（如 USB3.0、PCIe 等）需注意 120pF 的结电容可能影响信号完整性，建议评估是否采用低容型 TVS。
- 焊接与回流：遵循 SOD-323 封装的回流温度曲线与 PCB 生产工艺标准，避免长时间高温暴露影响器件可靠性。
- 在高能量冲击场合，确保周边铜箔与散热设计可承受能量转换产生的热量。
六、可靠性与选型提示
SD05.TCT 适合用于需要兼顾体积和防护能力的 5V 系统，但在极端高频或严格信号完整性要求的应用中，需评估结电容对信号的影响。选型时可根据系统允许的最大钳位电压、峰值电流与容性影响进行比对，必要时与低容抗ESD 器件或双向 TVS 组合使用。
七、包装与订购
封装：SOD-323 表贴；品牌：UMW（友台半导体）。订购时请注明型号 SD05.TCT、批次与封装要求，并参考厂家数据手册获取完整电气特性曲线与装配说明。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
