ER502_AY_10001 产品概述
一、产品简介
ER502_AY_10001 是 PANJIT（强茂）推出的一款快恢复、高效率整流二极管，封装为 DO-201AD 轴向封装。器件面向中高电压整流与开关整流场合，提供可靠的电气性能与较短的反向恢复时间，适合对转换效率和开关性能有要求的电源应用。
二、主要性能特点
- 正向压降 (Vf): 950 mV @ 5 A（典型值），在大电流整流时保持较低功耗。
- 最大直流反向耐压 (Vr): 200 V，适用于中高压整流场景。
- 连续正向整流电流 (If): 5 A，满足常见中功率负载。
- 反向漏电流 (Ir): 1 μA @ 200 V，漏电低，有利于高压待机与低损耗设计。
- 反向恢复时间 (Trr): 35 ns，属于快恢复类别，可减少开关损耗与电磁干扰。
- 非重复峰值浪涌电流 (Ifsm): 150 A，具备良好的抗浪涌能力。
- 工作结温范围: -55 °C ~ +150 °C，适应较宽温度环境。
- 封装: DO-201AD，轴向引线，便于波峰焊或手工焊接。
三、电气与热特性（实用提示）
- 在 5 A 工作点时，正向功耗约为 P = If × Vf ≈ 4.75 W，需注意散热设计与器件结温控制。
- 建议对持续工作在高电流、较高环境温度的场合进行热降额，确保结温不超过 150 °C。
- 35 ns 的反向恢复时间使器件适合数十至数百 kHz 的开关频率，但在高速高 dv/dt 场合要注意寄生电感引发的过冲与振铃。
四、典型应用
- 开关电源（SMPS）整流与续流二极管
- 电机驱动与逆变器的自由轮二极管
- 适配器、充电器主整流桥
- LED 驱动、电源滤波与保护电路
- 工业电源与家电中高压整流场合
五、设计与选型建议
- 若需更低正向压降（提高效率），可比较同电压等级的肖特基器件，但肖特基在高 Vr 或高温时漏电较大，应根据实际工况权衡。
- 在桥式整流或并联使用多只二极管时，应考虑电流均流与热平衡，必要时加阻值或采用热耦合设计。
- 在高频开关环境中，配合 RC 抑制或适当的 snubber 网络可抑制反向恢复引起的电压尖峰与 EMI。
- 做恒定电流或长时冲击时参考 Ifsm 与热降额，避免重复大幅度浪涌。
六、封装与可靠性、注意事项
- DO-201AD 轴向封装便于装配与检修，但对散热主要依赖引线与 PCB 末端散热路径，设计时应保留足够的铜箔面积与通孔散热。
- 在高温或高湿环境下使用前建议进行应用级验证；如有具体认证或可靠性需求（如 AEC-Q 等），请向供应商确认。
- 订购时请注明完整型号 ER502_AY_10001 及品牌 PANJIT（强茂），并索取最新数据手册以获取完整极限参数与典型特性曲线。

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.
