ER302_AY_10001 产品概述
一、概要说明
ER302_AY_10001 是 PANJIT（强茂）出品的一款 Super Fast Recovery 整流二极管，属独立式（轴向）封装，型号封装为 DO-201AD。该器件针对需要在中高速开关和整流环境下提供低损耗、抗浪涌能力强的整流方案而设计，适用于开关电源、逆变器与电机驱动等场合。
二、电气性能要点
- 直流反向耐压（Vr）：200V，适合中低压直流系统。
- 正向压降（Vf）：950mV @ 3A，低压降有助于减少导通损耗。
- 整流电流：3A（持续），满足常见中小功率整流需求。
- 非重复峰值浪涌电流（Ifsm）：125A，具备良好的抗浪涌冲击能力。
- 反向电流（Ir）：1μA @ 200V，漏电小，有利于降低待机功耗。
- 反向恢复时间（Trr）：35ns，属于 Super Fast 类别，可在较高开关频率下减少开关损耗与应力。
三、封装与机械特性
器件采用 DO-201AD 轴向玻璃/金属封装，结构坚固，便于自动化插件或手工焊接。轴向引线利于散热和在电路板上跨接使用。封装耐热与机械强度适合一般工业应用，但焊接时应遵循厂家焊接温度和时间要求以免损伤器件。
四、典型应用场景
- 开关电源（SMPS）次级整流或辅助电源整流。
- 功率因数校正、小功率逆变器的续流/整流回路。
- 电机驱动的自由轮二极管及抑制吸收回路。
- 工业控制、通讯设备和家用电器的整流与保护电路。
五、设计与布局注意事项
- 热管理：尽管器件允许工作结温 -55℃ 至 +150℃，在长期工作时应进行电流—温度降额。连续 3A 工作需考虑引线与环境散热，必要时配置散热片或保持良好空气对流。
- 开关过渡：Trr=35ns 虽然快速，但在高 di/dt 场合仍可能引起反向恢复产生的瞬态电压尖峰，建议在高频或高电感应用中配合阻容吸收网络或适当的缓冲电路以抑制 EMI 和过压。
- 浪涌保护：Ifsm=125A 表明器件能承受短时浪涌，但应评估系统内浪涌能量并配合熔断或限流措施以防反复冲击降低寿命。
- 布局：轴向引线便于布线，但应保证引线短直以减少寄生电感；在 PCB 上靠近热源处留出散热空间。
六、可靠性与采购建议
PANJIT（强茂）为国内外知名元器件厂商，产品通过常规可靠性测试和出厂检验。选型时请参考完整数据手册核对更详细的热阻、极限值与焊接工艺参数；批量采购时建议索取样片并进行针对性的整机级过压、浪涌与温度循环试验以验证在目标应用中的长期可靠性。订单请使用完整型号 ER302_AY_10001 并确认封装 DO-201AD 以避免型号混淆。

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.
