SD60C 产品概述
一、产品简介
SD60C 是东沃（DOWO）推出的一款单端向（单向）ESD 保护二极管，采用单片硅工艺，旨在替代便携式设备中常用的多层压敏电阻（MLV）。该器件响应快速、箝位电压低、漏电流小，适用于对静电放电和浪涌敏感的半导体元件保护。封装为无铅 SOD-323，PCB 占板面积与 0805 MLV 相同，便于在现有设计中替换使用。
二、主要参数
- 反向截止电压（Vrwm）：60 V
- 击穿电压（VBR）：69 V
- 钳位电压（典型）：100 V
- 峰值脉冲电流（Ipp）：7 A @ 8/20 µs
- 峰值脉冲功率（Ppp）：650 W @ 8/20 µs
- 反向电流（Ir）：300 nA
- 结电容（Cj）：12 pF
- 防护等级：符合 IEC 61000-4-5（浪涌）及 IEC 61000-4-2（ESD）
- ESD 性能：空气放电 ±15 kV，接触放电 ±8 kV
- 类型：ESD（单向）
- 封装：SOD-323（无铅）
- 品牌：DOWO（东沃）
三、主要特性与优势
- 响应速度快：硅基工艺保证纳秒级响应，有效吸收瞬态脉冲，保护敏感器件免受 ESD 损伤。
- 低钳位电压：典型钳位仅 100 V，可显著降低被保护节点承受的过压应力。
- 低漏电流：300 nA 的低反向电流适合便携式电源管理和高灵敏度信号接口。
- 低结电容（12 pF）：适合对带宽和信号完整性有要求的高速接口应用。
- 高脉冲承受能力：7 A/650 W（8/20 µs）确保在常见浪涌条件下可靠工作。
- 封装小巧：SOD-323 封装便于在空间受限的移动设备中布局，且兼容 0805 MLV 孔位。
四、典型应用
- 手机、智能终端、平板与笔记本的 I/O 接口保护
- 电源管理与充电接口保护（USB、Type-C、充电插座）
- 摄像头模块、传感器和射频前端的静电防护
- 个人数字助理、可穿戴设备及其他便携式电子产品
五、布局与使用建议
- 将 SD60C 靠近被保护的端口或连接器放置，减小走线感应环路，提升保护效果。
- 对单向器件，注意极性安装（阴极接地/参考点）；在双向需求场景选用对应型号。
- 在高功率或反复浪涌场景，配合合适的 PCB 散热与阻抗匹配设计以提高可靠性。
- 对高速信号线，评估结电容对信号完整性的影响，必要时采用差分或屏蔽措施。
六、注意事项与可靠性
- 虽然器件满足 IEC 61000-4-2/4-5 标准，但实际系统级保护应结合阻抗、屏蔽与接地设计共同验证。
- 长期工作在高温或高应力环境会影响击穿与钳位特性，建议按照器件规格书进行热管理与余量设计。
- 在更高能量浪涌或多次脉冲情况下，应进行整机级测试以确认寿命与失效模式。
SD60C 以其低钳位、高可靠性与小尺寸优势，适合用于对体积与性能均有严格要求的便携式设备静电与浪涌保护。有关更详细的电气特性曲线、封装尺寸和应用电路，请参考东沃提供的产品规格书与参考设计。

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.
