AH1808-W-7 是 DIODES(美台)推出的一款全极型(双极性)霍尔开关器件,采用小型表贴封装 SC-59,适合对功耗、尺寸与抗干扰要求较高的磁场检测与开关应用。器件在低电压下工作稳定,输出为开漏结构,便于与多种逻辑电平系统接口。
SC-59 封装体积小,便于贴片工艺。焊盘设计应遵循制造商推荐的 PCB 尺寸以保证焊接质量与热性能。布线上,应将敏感信号线与高电流回路隔离,避免磁干扰影响触发点。
AH1808-W-7 的低功耗与宽电压特性使其在电源管理或省电唤醒方案中具有优势。选型时关注工作点与实际应用中磁体强度的匹配,留有足够的裕量以避免温漂与装配误差导致误触发。需要更详细的电气特性曲线、引脚排列与灵敏轴信息时,建议查阅 DIODES 官方数据手册或联系供应商获取样品验证。
总结:AH1808-W-7 以其全极型响应、超低电流、宽工作电压与小型封装,适合各类对能耗与空间敏感的磁感开关应用,是可靠且实用的霍尔开关选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
