BAV21WS 产品概述

一、产品简介

BAV21WS(品牌:YANGJIE/扬杰)是一款独立式高压快速开关二极管,封装为SOD-323,适用于空间受限的表面贴装电路。该器件在200mA工作电流下正向压降仅约1.25V,反向耐压高达250V,兼顾高压耐受能力与快速开关性能,适合小信号与功率受限的开关与整流应用。

二、主要电气参数

  • 最大直流正向电流(整流电流):200mA
  • 正向压降:1.25V @ 200mA
  • 直流反向耐压(Vr):250V
  • 反向电流:100nA @ 200V
  • 非重复峰值浪涌电流(Ifsm):500mA(瞬态)
  • 耗散功率(Pd):250mW
  • 反向恢复时间(Trr):50ns
  • 工作结温范围:-65℃ ~ +150℃(Tj)

这些参数表明,BAV21WS在高压、低漏电流及中等开关速度场合表现优良,特别适合对漏电流敏感或需要较高反压的应用。

三、典型应用场景

  • 高频开关与信号整形电路
  • 低功率高压整流与检测(如测量、保护)
  • 反相/极性保护与低电平逻辑隔离
  • 开关电源的启动或高压检测回路
  • 射频前端的小信号整流与钳位(需结合具体频率测试)

四、热与可靠性要点

在200mA正向工作时,器件功耗约为0.25W(P = I·V = 0.2A·1.25V),已接近Pd标称值250mW;因此在持续工作条件下需重视散热与电流裕度。SOD-323为小型封装,建议在PCB设计时优化铜箔散热与焊盘热通道,避免长期在高环境温度下满载工作。遵循厂商回流焊曲线(峰值温度 ≤ 260℃)进行贴片焊接,存储与操作时防潮防静电,按厂家说明处理。

五、使用建议

  • 尽量避免长期满额定电流运行,推荐留有安全裕度(例如工作电流≤额定值的70%-80%)以延长寿命并降低结温。
  • 对开关速度有更高要求的场合,请结合实际电路测试Trr引起的反向恢复振铃与损耗。
  • 在高阻抗或高精度测量电路中,可利用其低反向漏电(100nA@200V)特性,但仍需考虑环境温升对漏电的影响。
  • 短时浪涌(≤Ifsm)允许500mA,但避免重复或长时间浪涌。

六、封装与采购提示

SOD-323封装适合高密度SMT组装,适用于自动贴片生产线。订购时请确认完整型号(BAV21WS)、品牌(YANGJIE/扬杰)、以及包装形式(卷带/盘带)以满足生产需求。需要更详细的封装尺寸、电气特性曲线及回流焊参数,请参照厂商数据手册或向供应商索取样片与测评数据。

总结:BAV21WS为一款兼具高压耐受、低泄漏与快速开关特性的SOD-323封装二极管,适合空间受限且需高压小电流整流或快速开关的电子设计。

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.
