WH2508F-3/TR 产品概述

一、产品简介

WH2508F-3/TR 是韦尔(WILLSEMI)推出的一款全极型霍尔效应开关型传感器,适用于在低功耗及狭小空间内实现磁场检测与开关控制。器件工作电压范围宽(1.6V5.5V),在-40℃+85℃的工业级温度范围内稳定运行,适配多种嵌入式与消费类应用。

二、主要特性

  • 类型:全极型(对南北极均能响应);数字开关输出,便于与 MCU 或逻辑电路直接接口。
  • 工作电压:1.6V ~ 5.5V,支持低电压系统。
  • 工作点(Operate,Gs):+3.6 mT / -3.7 mT;释放点(Release,Gr):+2.5 mT / -2.6 mT,给予约 1.1 mT 左右的滞后,抑制抖动。
  • 静态工作电流:典型 3.35 µA,极低功耗,适合电池供电设备。
  • 工作温度:-40℃ ~ +85℃,满足工业级环境需求。
  • 封装:TSOT-23-3L,体积小、易于贴片加工。

三、引脚与封装

WH2508F-3/TR 采用 TSOT-23-3L 小封装,常见引脚排列为 VCC、GND、OUT(请参考厂方引脚图与原理图)。输出为数字开关信号,可通过外接上拉电阻连接到系统电源或 MCU IO。/TR 后缀表明供应形式为带卷带(Tape & Reel),适合SMT自动贴装。

四、典型应用

  • 位置与限位检测(门、盖、机构到位感知)
  • 速度/转子极位检测(小型无刷电机补偿)
  • 轴位置与齿轮角度判断
  • 无接触开关与安全检测
  • 可穿戴设备、便携仪器的低功耗磁感测

五、设计注意事项与使用建议

  • 磁体与传感器之间的空气间隙及磁体取向直接影响触发点,设计时需做样机验证以确定最佳距离与磁强。
  • 由于器件有滞后(Operate 与 Release 差值),可有效抑制抖动,但在精确位置控制场合应评估滞后影响。
  • 输出端如需驱动较大负载,应使用外部驱动器或晶体管,避免超出器件能力。
  • 焊接和回流时遵循器件的最高温度限制与厂方推荐的焊接曲线,防止热损伤;注意 ESD 防护与存储防潮等级。

六、包装与型号说明

型号 WH2508F-3/TR 中 TR 表示 Tape & Reel 包装形式,适合大批量 SMT 生产。采购与生产时建议参考厂方完整数据手册以获取电气特性曲线、典型应用电路与可靠性数据。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
