UDZVFHTE-173.3B 是 ROHM(罗姆)提供的一款小功率稳压二极管,标称稳压值为 3.3V,最大耗散功率为 200mW。该器件采用 SC-90 小型贴片封装,适合高密度表面贴装电路。凭借紧凑的体积与简单的外接电路需求,适用于对成本和尺寸敏感的低功耗电源箝位、基准与钳位应用场景。
注:以上为器件的典型/标称参数,实际应用中应参照厂商完整数据手册和测试条件进行设计验证。
SC-90 封装体积小、重量轻,适合自动化贴装。由于封装热阻相对较高,在高功耗工况下需要注意热管理。ROHM 品牌通常提供良好的生产与检验控制,建议在关键应用中参考厂方的可靠性测试与环境适应性数据。
总结:UDZVFHTE-173.3B 是一款面向小尺寸、低成本应用的 3.3V 稳压二极管,适合做电平钳位与低功耗的基准/稳压用途。在实际设计中需关注其动态阻抗与功耗限制,合理选择工作电流并做好热设计,以保证长期可靠运行。

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.
