PESD1LIN 是 UMW(友台半导体)推出的表面贴装型 TVS(瞬态电压抑制)二极管,面向对浪涌和静电放电保护有较高要求的线路设计。该器件为单路、双向保护,采用 SOD-323 小封装,适合空间受限的消费电子、通信和工业设备中作为输入/输出端或电源防护件使用。
PESD1LIN 采用 SOD-323 小型封装,装配时建议将器件尽可能靠近被保护的连接器或引脚放置,减小寄生电感与回路面积。双向器件通常无极性方向限制,但请参考封装标识以保证一致性。设计时留意焊盘尺寸与与焊接热循环兼容性,遵循厂商推荐回流焊曲线以保证可靠性。
PESD1LIN 针对 IEC 61000-4-5 浪涌测试条件设计,8/20 µs 测试脉冲下具备标称吸收能力。器件在正常工作温度与推荐焊接条件下具有良好的长期可靠性,适用于工业与消费类环境。具体环境应力与寿命评估建议结合实际应用做加速试验验证。
PESD1LIN 在小封装下提供了较高的瞬态吸收能力、低结电容与超低漏电流,适合对空间、信号完整性与低功耗要求并存的保护场景。可选的钳位电压(44 V / 70 V)便于在不同工作电压等级中灵活部署,是一种通用、成本效益高的瞬态防护解决方案。
如需更详细的电气特性表、钳位电压曲线或 PCB 焊盘建议图,请告知我所需型号(44V 型或 70V 型)及应用场景,我可以提供针对性的建议与参考数据。

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.
