MDD HER208 高效率整流二极管产品概述
一、产品简介
MDD HER208 为高效率整流二极管，采用 DO-15 轴向引线封装，额定直流正向电流 2A，直流反向耐压 1000V。器件针对开关电源与整流应用进行了优化，具有较低的正向压降与较小的反向恢复时间，适合中高频整流与保护回路使用。
二、关键电气参数
- 正向压降 (Vf)：1.7V @ 2A
- 直流反向耐压 (Vr)：1000V
- 正向整流电流：2A（连续）
- 反向电流 (Ir)：5µA @ 1000V
- 反向恢复时间 (Trr)：70ns
- 非重复峰值浪涌电流 (Ifsm)：60A（单次浪涌）
- 工作结温范围 (Tj)：-65℃ ~ +150℃
三、主要特性与优势
- 低正向压降：在额定电流下 Vf=1.7V，有助于降低整流损耗与发热，提升效率。
- 高耐压能力：1000V 反向耐压适用于高电压整流与隔离电源应用。
- 快速恢复：70ns 的反向恢复时间减少开关损耗与电磁干扰（EMI），适合开关电源和逆变器场合。
- 低反向泄漏：5µA @1kV 的低漏电流有利于高压小电流回路的稳定性。
- 高浪涌承受力：60A 的非重复峰值浪涌电流可应对启动或短时过载情形。
四、典型应用
- 开关电源（SMPS）整流与自由轮回路
- 工业电源与高压整流模块
- 逆变器和电机驱动的续流二极管
- 高压保护与阻断电路
五、安装与可靠性建议
- 封装为 DO-15 轴向形式，适合手工或波峰/回流焊接的引线安装。注意引线焊接温度与时间以避免热损伤。
- 在长期工作时应考虑结温管理与散热路径，必要时增加散热片或改善气流。
- 浪涌应用需遵循 Ifsm 限值，避免重复超过峰值浪涌导致器件失效。
- 在高压环境测试中，建议按产品规格进行耐压、漏电与温升验证。
六、选型与替代
HER208 适合需要 1kV 耐压且有一定开关频率要求的场景。选型时如需更低 Vf 或更短 Trr，可考虑肖特基或专用快恢复器件；如需更高电流能力，应选择更大封装或并联方案并注意均流与热管理。

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.
