SD05C-01FTG 是 DOWO(东沃)推出的一款单路双向瞬态抑制二极管(TVS),采用 SOD-323 小型封装,专为 5V 及近似电压系统的瞬态浪涌与静电放电(ESD)保护设计。器件具有快速响应、高峰值脉冲吸收能力和宽工作温度范围,适合功耗受限且空间要求严格的便携式与工业电子产品防护应用。
SD05C-01FTG 在正常工作时对系统影响小,处于高阻态;当输入端遭受瞬态高压(如静电放电或脉冲干扰)时,TVS 二极管迅速导通,将能量泄放至地线或对称端,从而夹紧电压并保护后端敏感电路。双向结构适合交流或双向传输线的保护,无需额外极性判断。
注意:器件结电容约 60 pF,属于中等偏高水平,因此不建议用于对电容极为敏感的高速差分信号(如 USB3.0、HDMI 或高速以太网)对接线,对这些应用应选择低电容型 TVS。
SOD-323 封装体积小、适合自动贴装与回流焊,便于在有限空间内进行防护布局。工作温度范围宽,适应工业级应用。器件符合 IEC 61000-4-2 与 IEC 61000-4-4 标准测试要求,可在常见静电与脉冲干扰环境下提供可靠防护。
SD05C-01FTG 适用于需要在 5V 级别提供高能脉冲吸收能力且空间受限的保护方案。选型时关注钳位电压与系统耐受电压匹配、峰值脉冲能力与实际冲击能量余量。若目标应用对信号电容敏感,请考虑更低 Cj 的替代型号或在保护策略上采用隔离/耦合方案。
总体而言,SD05C-01FTG 在小型化封装下实现了较高的脉冲吸收能力与良好的工业环境适应性,是便携设备、低速数据线及一般电源接口等场景的实用保护元件。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
