HER108G 产品概述
一、产品简介
HER108G 为扬杰（YANGJIE）推出的一款快恢复、高效率整流二极管，采用 DO-41 轴向封装，适用于中高压整流与开关电源回路。器件在 1A 工作电流条件下具有较低的正向压降与较短的恢复时间，兼顾整流效率与开关性能，便于在空间受限的传统轴向安装场合使用。
二、主要参数
- 型号：HER108G（YANGJIE 扬杰）
- 正向压降 Vf：1.7V @ IF=1.0A
- 直流反向耐压 Vr：1000V（1kV）
- 连续整流电流 IF：1A
- 反向电流 Ir：2.5µA（常温）
- 反向恢复时间 Trr：75ns
- 非重复峰值浪涌电流 Ifsm：30A（单次脉冲）
- 工作结温范围：-55℃ ~ +150℃
- 封装：DO-41（轴向）
三、主要特点
- 高耐压：1kV 的反向耐压适合高压整流和高压开关电源应用。
- 快恢复：75ns 的反向恢复时间，显著降低开关损耗与电磁干扰（EMI），提高转换效率。
- 低漏电：2.5µA 的低反向电流有助于减小高压侧待机功耗与热量积累。
- 良好浪涌承受能力：30A 的单脉冲浪涌能力，满足开机浪涌与短时尖峰电流需求。
- 宽温度适应：-55℃ 至 +150℃ 的结温范围，适合严苛环境与工业级应用。
四、典型应用场景
- 开关电源（SMPS）输出及整流桥二极管
- 功率整流、直流母线整流器
- 逆变器与电机驱动的自由轮二极管（在允许的电压电流范围内）
- LED 驱动器、高压脉冲电源与充电设备中的高压整流
- 工业设备、家电与电源模块的替换与维护
五、封装与热管理
DO-41 轴向玻璃钝化封装便于手工焊接与波峰贴装，但其热阻较大，需在设计中考虑散热路径：
- 在高平均电流或高环境温度场合，建议将二极管夹持于散热良好的金属支架或尽量缩短连接引线以降低热阻。
- 注意峰值浪涌（Ifsm）为非重复单次值，长期重复浪涌需遵循热循环与平均功耗限制。
六、使用建议
- 在开关电源回路中配合合适的缓冲电路与压敏元件，控制过冲与瞬态电压，延长器件寿命。
- 设计时按最大结温与功耗计算允许平均电流，必要时并联多只或采用更大封装的器件。
- 选型时注意正向压降随电流与温度上升而变化，对效率敏感的场合可评估更低 Vf 的替代器件。
HER108G 以其高电压耐受、快恢复特性和可靠的轴向封装，适合多种中高压整流与开关场合，是替换老式硅整流器与提升开关效率的实用选择。

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.
