BAT54WS_R1_00001 产品概述

一、产品简介

BAT54WS_R1_00001 是强茂(PANJIT)出品的一款小信号肖特基二极管,采用双向(或双并)二极管结构并封装于 SOD-323 小型封装。该器件以低正向压降、快速恢复和低反向电流为特点,适用于便携式电子、信号整流与瞬态保护等对体积和效率有较高要求的应用场景。

二、主要电气参数

  • 正向压降 (Vf):约 600 mV @ If = 100 mA
  • 直流反向耐压 (Vr):30 V (最大反向工作电压)
  • 平均整流电流 (If):200 mA
  • 反向电流 (Ir):典型 2 μA @ Vr = 25 V, Tj = 25°C
  • 非重复峰值浪涌电流 (Ifsm):1 A(单次脉冲)
  • 工作结温范围:-55°C 至 +125°C

三、器件特点与优势

  1. 低正向压降:在中低电流工作点(如 100 mA)下 Vf ≈ 600 mV,降低整流与开关损耗,提升系统能效。
  2. 低反向漏电流:25 V 时 Ir 约 2 μA,适合对待机功耗与泄漏要求严格的电路。
  3. 小型封装:SOD-323 占板面小,便于高密度贴片与便携设备设计。
  4. 较高的冲击承受能力:1 A 峰值浪涌电流可应对瞬态电流冲击(短时间脉冲)。
  5. 宽温度范围:-55°C 至 +125°C,适应工业级温度环境。

四、典型应用场景

  • 低电压整流与电源二极管(小型充电器、USB、移动设备)
  • 电源反向保护与低压降整流路径
  • 快速切换和混合信号隔离电路
  • 瞬态电压抑制(配合限流元件)与浪涌保护
  • 高频信号路径中的钳位与整流(在功率要求不高时)

五、封装与安装注意事项

  • 封装:SOD-323,小型表贴(SMT),焊接时推荐遵循制造商的回流焊曲线,避免过高温度或超时造成性能退化。
  • 焊盘设计:为降低热阻与应力,建议按推荐 PCB 焊盘尺寸布局,并在焊盘周围留足铜箔用于散热。
  • ESD 与静电敏感性:虽然肖特基二极管本身抗浪涌能力有限,但在生产与装配过程中仍应采取基本静电防护措施。

六、热管理与可靠性提示

  • 该器件额定平均整流电流为 200 mA,长期大电流工作时需关注结温上升与功耗(Pf = Vf × If)。
  • 反向漏流随温度急剧上升,高温环境下 Ir 可能显著增加,应在高温工况下进行验证。
  • 在可能出现高能量浪涌的应用(例如电源插拔)中,建议配合限流或缓冲电路使用。

七、选型与替代建议

  • 若需要更高电流能力或更低 Vf,可考虑更大封装或专用功率肖特基型号。
  • 若反向耐压需超过 30 V,应选用 Vr 更高的肖特基或普通整流二极管。
  • 与其它品牌和型号比较时,请同时参考 Vf、Ir、Ifsm、工作温度及封装尺寸等参数以满足电路限制。

八、储存与运输

  • 储存环境干燥、避免潮湿,建议按照制造商预装带(tape & reel)及防潮包装的要求保存与回流焊前的烘烤规范处理。

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
