SR05 是友台半导体(UMW)推出的一款单向瞬态电压抑制(TVS)二极管,专为 5V 工况的电路板浪涌保护而设计。器件采用 SOT-143 小体积封装,工作温度范围宽(-55℃ 至 +125℃),可以在有限空间内为敏感接口提供快速、可靠的过压防护,满足 IEC 61000-4-5 的浪涌抗扰度要求。
SOT-143 小封装便于高密度布局,但对热耗散能力有限。在频繁或高能量浪涌环境下,建议在器件周围保持适当铜箔面积以利散热;必要时在 PCB 顶层与底层增加过孔连接,以增强导热与提升可靠性。
型号示例:UMW SR05,封装 SOT-143。订购时请确认所需极性(单向)与工作电压等级(Vrwm=5V)匹配应用要求。出货前建议参考厂方完整数据手册,核对钳位电压测试条件、热阻参数及可靠性试验报告,以确保器件在目标系统中的长期稳定性。

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.
