ER3MB-TP 产品概述
一、产品简介
ER3MB-TP 是美微科（MCC）推出的一款高电压、大电流的表面贴装整流二极管，封装为 DO-214AA（SMB）。器件针对工业级开关电源和高压整流应用优化，兼顾稳健的耐压能力与良好的脉冲浪涌承受力，适合在空间受限但散热措施到位的线路中替代传统轴向整流器件。
二、主要参数
- 正向压降（Vf）：1.7V @ IF = 3A
- 直流反向耐压（Vr）：1000V
- 额定整流电流：3A（持续）
- 反向电流（Ir）：5µA @ VR = 1000V
- 反向恢复时间（Trr）：75ns（中速恢复）
- 非重复峰值浪涌电流（Ifsm）：100A（单次脉冲）
- 工作结温范围：-55℃ ~ +150℃
- 封装：DO-214AA（SMB），表面贴装
三、关键特性
- 高耐压：1000V 的反向耐压使其适用于高压整流与高压回路保护。
- 低反向漏流：5µA@1kV 的低漏电特性在高压静态条件下可减少能耗并降低热应力。
- 中速恢复：75ns 的反向恢复时间适合多数开关电源、逆变与整流场合，在效率与开关损耗之间取得平衡。
- 良好浪涌承受力：100A 的单次浪涌能力可应对短时启动或故障脉冲电流。
- SMB 表面贴装：适合自动化贴片与回流焊工艺，利于批量制造与可靠性控制。
四、典型应用场景
- 开关电源（SMPS）次级整流与高压整流桥
- 功率因数校正（PFC）电路中的整流与回收路
- 逆变器与驱动电源中的二次侧整流
- 高压充电器、工业电源与测试设备
- 需要低漏电、高耐压的保护与钳位电路
五、封装与安装建议
- 封装为 DO-214AA（SMB），建议采用与器件热阻匹配的 PCB 过孔与铜箔散热措施，必要时在焊盘下方增加热通孔并连接至散热层。
- PCB 布局中应保持高电流回路短而宽，尽量减小寄生电感以降低开关损耗与振铃。
- 采用标准回流焊工艺，遵循焊料与温度曲线的规范，避免长时间高温存放导致引脚和封装应力。
六、可靠性与工程注意事项
- 持续整流电流受环境与散热影响，3A 额定值需在合理散热条件下使用，应考虑结温随功耗上升的降额策略。
- 反向峰值电压与浪涌电流同时出现时应注意器件极限，长时间重复的冲击可能导致寿命下降。
- 设计时为降低开关损失，可配合合适的阻尼与滤波网络以抑制回收电流峰值。
- 在高压弱电或测量场合，低漏电特性有利于提高精度，但仍需考虑环境湿度与爬电距离的布线规则。
ER3MB-TP 结合了高耐压、低漏电与良好的浪涌能力，适合对体积与性能有综合要求的高压电源与工业控制应用。选择与布板时以热管理与开关布局为重点，可发挥该器件的最佳性能。

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.
