BAS17,215 为安世(Nexperia)BAS17 系列中的低压稳压二极管(低压 stabistor)表面贴装型号,封装为 SOT-23,采用独立式二极管配置。器件设计用于在低电流范围提供稳定的参考或钳位电压,典型标称稳压值约 5 V,最大工作电流可达到 200 mA(视散热条件与使用方式而定)。典型的反向漏电流 Ir 为 5 µA,最大功耗 Pd 标称 250 mW。
注:具体电参数(如精确稳压电压、动态电阻、温度系数、最大反向电压等)应参照安世官方数据手册以获得完整的规范与测试条件。
SOT-23 为三引脚封装,常见引脚用法为:阳极、阴极与空/连接结构(或用于并联/散热)。封装体积小、寄生电感低,便于高密度 PCB 设计。推荐遵循厂家提供的 PCB land pattern 与回流焊工艺参数,避免过高的焊接温度与过长的加热时间以保护器件。
选择时建议确认数据手册中的测试条件(测试电流、温度、漏电测量电压等)。如需更高功耗或更低漏电可考虑同厂或其他厂家的高功率/低漏型稳压二极管,或采用表面贴装功率更大的封装(SOD-123、SOD-128 等)以满足散热需求。
BAS17,215 以其 SOT-23 小型化封装与低漏电、5 V 级稳压特性,适合板级偏置、参考及轻载钳位应用。在设计中应重视散热和电流限制,遵循厂家手册的电性能测试条件与焊接规范,以保证长期可靠性与稳定性。若有更高电流或更严格精度要求,建议参考官方数据手册或联系供应商获取推荐替代型号与应用参考电路。

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.
