BAV21W 产品概述
一、产品简介
BAV21W（GOODWORK 固得沃克，SOD-123 封装）是一款通用独立式二极管，面向中低功率整流与开关场合设计。器件耐压高、反向漏电小、反向恢复时间适中，适合交流整流、过压钳位、信号切换及保护电路等多种应用。
二、关键参数
- 封装：SOD-123（独立式）
- 工作结温范围：-55℃ ~ +150℃
- 正向压降（Vf）：1.25V @ 200mA
- 额定整流电流：250mA（平均）
- 非重复峰值浪涌电流（Ifsm）：1A
- 直流反向耐压（Vr）：250V
- 反向电流（Ir）：100nA @ 250V
- 反向恢复时间（Trr）：50ns
- 功耗（Pd）：500mW
三、主要特性
- 高耐压：250V 反向耐压可满足多数中高压整流与保护需要。
- 低漏电：100nA 的典型反向电流在高阻抗输入或高精度模拟电路中有利于抑制误差。
- 中等速度恢复：50ns 的反向恢复时间适用于一般开关频率下的整流与开关用途。
- 小体积封装：SOD-123 便于表面贴装、节省 PCB 面积并适合自动化贴装流程。
四、典型应用
- 交流小功率整流与开关电源滤波辅助整流。
- 信号切换、脉冲隔离与钳位电路。
- 过压/反向保护、输入防反接电路。
- 仪表与通信设备的高压隔离与整流场合。
五、使用与布局建议
- 留意正向压降与功耗，连续工作时按热阻和环境温度做功率降额。
- 尽量减短走线和环路面积，以降低寄生电感带来的电压尖峰和 EMI。
- 在高频开关场合，若要求更短的 Trr 或更低 Vf，可考虑专用快恢复或肖特基二极管。
- 焊接与回流温度遵循 SOD-123 工艺规范，避免超过器件最大结温。
六、可靠性与选型提示
- 对漏电流与温漂敏感的设计，应在系统级测量不同温度下的 Ir。
- 若预计有大电流冲击或更高平均电流需求，应选用更大功率或并联多只器件并做好电流均流设计。
- 订购型号示例：GOODWORK BAV21W，封装 SOD-123；批量采购时关注批号与品质认证。
以上为 BAV21W 的概要说明，便于在电路设计、元件选型与可靠性评估时参考。若需等效电路参数、典型波形或在具体电路中的仿真数据，可提供电路条件以便进一步分析。

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.
