ER3DA_R1_00001 产品概述
一、产品简介
ER3DA_R1_00001 是强茂（PANJIT）推出的一款 Super Fast Recovery 整流二极管，封装为 DO-214AA（SMB），额定整流电流 3A，反向耐压 200V。该器件针对开关电源、功率整流与保护场合优化，兼顾低正向压降与快速恢复特性，适用于要求开关频率较高且需降低开关损耗的电源与逆变应用。
二、主要特点
- 正向压降 (Vf)：0.95V @ IF=3A，导通损耗低。
- 直流反向耐压 (Vr)：200V，适应中高压工况。
- 反向电流 (Ir)：1μA @ Vr=200V，漏电小，静态损耗低。
- 反向恢复时间 (Trr)：35ns（典型），开关损失与电压应力降低。
- 工作结温范围：-55℃ 至 +150℃，适应宽温度环境。
- 封装：DO-214AA（SMB），便于自动贴装与中功率散热设计。
三、电气与热学参数（关键）
- 连续整流电流：3A（环境与PCB散热条件相关），请根据实际板级散热设计评估。
- 峰值与瞬态参数：用于教育性说明，建议在具体设计时参照强茂正式数据表获取脉冲峰值电流与非重复浪涌能力。
- 热管理：结—环境热阻依赖封装与PCB铜箔面积，建议在高负载时扩展散热通道或增加散热片。
四、封装与安装
- 封装类型：DO-214AA（SMB），极性明显，阴极端有标识（请以实物标记为准）。
- 焊接：支持回流焊与波峰焊，应遵循制造商的焊接曲线与湿储等级（MSL）要求。
- PCB 布局：为降低结温，建议增加焊盘铜箔面积并通过过孔与大面积接地/散热层导热。
五、典型应用
- 开关电源（SMPS）整流与续流。
- 逆变器与电机驱动的续流二极管。
- 功率因数校正（PFC）电路的恢复二极管。
- 保护电路、硅稳压与箝位场合中需快速恢复的整流元件。
六、选型与注意事项
- 若工作频率非常高或要求更低开关损耗，可比较 Schottky 或更高速恢复器件的 trade-off（结温、反向耐压与漏电）。
- 在高温或高应力工况下，应按实际板级热阻评估允许平均电流，避免长期过热。
- 采购与生产应用时，请以强茂（PANJIT）正式数据手册为准，核对器件批次与封装标识。
七、总结
ER3DA_R1_00001 为一款面向中功率、高开关频率场合的 200V Super Fast Recovery 整流器，具有低 Vf、低 Ir 与较短 Trr 的平衡特性，适合在 SMPS、续流及保护电路中替代传统慢恢复整流器以降低开关损耗与电磁干扰。选用时应结合实际散热设计与工作波形，参照制造商完整资料确保可靠运行。

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.
