BAV21W-AU_R1_000A1 产品概述
一、概述
BAV21W-AU_R1_000A1 是强茂（PANJIT）推出的一款小型表面贴装开关二极管，采用 SOD-123 封装。器件面向通用高速开关和低功耗整流应用，具有较低正向压降、极小的反向漏电与快速反向恢复特性，适合空间受限的消费电子与工业控制电路。
二、主要参数
- 正向压降 Vf：1.0V @ IF=100mA
- 直流反向耐压 Vr：200V
- 最大整流电流 IF(AV)：200mA
- 额定耗散功率 Pd：410mW
- 反向电流 Ir：100nA @ VR=200V
- 反向恢复时间 Trr：50ns
- 工作结温范围：-55℃ 至 +150℃
- 非重复峰值浪涌电流 Ifsm：4A
- 封装：SOD-123，表面贴装
三、特色与优势
- 低漏电：在高压工作条件下仍保持微安级以下的反向电流，适合高阻抗或待机电路。
- 快速开关：50ns 的反向恢复时间有利于提高开关频率并降低开关损耗与干扰。
- 小体积高可靠：SOD-123 封装兼顾空间利用与焊接可靠性，适合自动贴装生产。
- 宽温范围：-55℃~+150℃ 的结温等级满足严苛环境应用需求。
四、典型应用
- 高频开关电路与脉冲整流
- 信号恢复与保护回路（钳位、反向保护）
- 便携设备、电视机顶盒、光通信收发模块的高速整流
- 工业控制与测量仪器中对漏电及切换速度有要求的场合
五、封装与可靠性
SOD-123 表面贴装封装利于回流焊工艺与高密度 PCB 布局。器件遵循行业常规的温度循环与机械可靠性测试，适用于批量 SMT 生产。建议按厂商提供的焊接曲线执行回流焊，避免长时间过高温度以保护器件性能。
六、使用与热管理注意事项
- 由于 Pd=410mW，需在 PCB 布局时考虑铜箔散热与合理走线，避免长期大电流工况造成结温过高。
- 在高压应用中，对反向漏电与耐压裕度进行验证；在要求更严格的漏电限制时，应对样片进行温度与电压应力测试。
- 推荐 ESD 与焊接防护措施，按强茂资料进行存储与焊接操作。

Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
