SD05C 产品概述
一、产品简介
SD05C 是 Leiditech（雷卯电子）推出的双向瞬态电压抑制器（TVS），专为5V工作电压的信号与电源线路提供瞬态过压保护。器件封装为 SOD-323，体积小、贴装方便，适合空间受限的消费类与工业电子产品。器件在 8/20μs 浪涌条件下可承受最高 320W 峰值脉冲功率，并通过多项电磁兼容等级测试（IEC 61000-4-2、4-4、4-5）。
二、主要特点
- 双向保护，能同时抑制正负极性瞬态过压。
- 反向截止电压 Vrwm：5V，适配 5V 电源/信号线。
- 击穿电压 Vbr(min)：6V，钳位电压典型值约 17V（在规定脉冲条件下）。
- 峰值脉冲电流 Ipp：15A；8/20μs 峰值脉冲功率 Ppp：320W。另 Ipp@10/1000μs：15A。
- 结电容 Cj：约 25pF，适用于高速信号线保护，影响较小。
- 反向漏电流 Ir：≤10μA，低功耗待机影响小。
- 工作温度范围：-55℃ ～ +125℃，可靠性高。
- 小外形 SOD-323 封装，便于自动化贴装。
三、关键参数说明
- Vrwm（反向截止电压）5V：建议用于标称5V系统（如 USB、串口供电等）。
- Vbr（击穿电压）6V：器件进入导通状态的最低电压门槛。
- 钳位电压 17V：在指定脉冲电流下的电压上限，决定被保护器件所承受的最大电压应力。
- Ppp 与 Ipp：320W@8/20μs 和 15A 的能力表明可吸收常见雷击与浪涌事件的瞬态能量，但重复脉冲需参照厂方曲线进行热、能量降额处理。
- Cj 25pF：对高速差分信号影响较小，适合数据线保护要求。
四、典型应用
- USB、HDMI、I2C、UART 等 5V 信号与接口防护。
- 工业控制与通信接口的浪涌与静电放电保护。
- 消费电子、机顶盒、路由器、监控设备等前端防护。
- EMI/ESD 易发环境中的输入端保护。
五、设计与使用建议
- TVS 尽量靠近受保护的连接器或器件放置，缩短导线长度以降低共模感应。
- 对地走线应尽量粗短并配合单点接地或专用地平面，改善散热与快速回流路径。
- 对于重复或长时间高能量脉冲场景，应参照厂方能量/温升曲线进行降额设计，必要时并联外部限流器件或使用更高功率等级 TVS。
- 在差分高速线（如 USB）应用时，注意匹配结电容，避免信号失真。
六、可靠性与注意事项
SD05C 已通过 IEC 61000-4-2（静电放电）、IEC 61000-4-4（电快速瞬变）与 IEC 61000-4-5（浪涌）相关测试，能满足常见工业与消费类电磁兼容要求。选型时应确认实际工作环境的最大瞬态能量、重复脉冲特性及系统接地方式，必要时联系厂商获取更详尽的脉冲测试曲线与包装信息（卷盘数量、封装说明等）。
如需进一步的电气特性曲线、封装尺寸或参考电路建议，可提供后续资料以支持设计验证与可靠性评估。

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.
