1N4727APF是一款小功率稳压二极管,核心参数清晰明确:标称稳压值为3V,稳压值范围覆盖2.85V~3.15V(满足±5%精度要求);反向漏电流(Ir)在反向电压1V时为150μA;动态阻抗方面,测试电流下Zzt=10Ω、Zzk=400Ω;最大耗散功率(Pd)为1W;封装采用标准DO-41轴向引线形式,品牌为ST(先科)且为无铅环保封装。这些参数是判断其应用场景与性能的关键依据。
该器件采用DO-41封装,属于轴向引线塑料封装,结构紧凑、尺寸小巧(直径约2.7mm,长度约4mm),便于手工插件或自动贴装(插件式),适配各类电路板的布局需求;无铅封装符合RoHS指令及国内环保标准,不含铅、镉等有害物质,可用于对环保要求较高的电子设备(如医疗、消费类电子产品)。DO-41封装的热传导性能稳定,能有效散发布器件工作时产生的热量,辅助保障其在额定功耗内的长期可靠性。
1N4727APF因参数适配性强,广泛应用于以下场景:
ST(先科)作为国内知名半导体厂商,其1N4727APF稳压管经过严格的生产工艺管控,参数一致性好,批量产品的稳压值、漏电流等指标偏差均在规格书范围内;产品通过了常规可靠性测试(如温度循环、湿度老化),可在-55℃~+150℃的宽温度范围内稳定工作,适用于工业控制、消费电子、汽车电子(部分场景)等多领域;无铅封装符合国际环保标准,可满足出口产品的合规要求。
该器件凭借稳定的稳压性能、紧凑的封装及环保特性,成为小功率电路中电压基准、过压保护的常用选择。

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.
