MURS160 产品概述
一、产品简介
MURS160 是 DOWO（东沃）推出的一款低功耗快速恢复整流二极管，单只独立式封装，SMB 表面贴装形式，额定正向电流 1A、直流反向耐压 600V。该器件兼顾了较低的正向压降与较快的反向恢复特性，适用于多种电源整流与开关应用场景，提供可靠的耐压与抗冲击能力。
二、主要电气参数
- 正向压降 (Vf)：1.25V @ 1A
- 直流反向耐压 (Vr)：600V
- 平均整流电流：1A
- 反向电流 (Ir)：5µA（典型/最大条件下）
- 反向恢复时间 (Trr)：38ns
- 非重复峰值浪涌电流 (Ifsm)：60A（单次浪涌）
- 工作结温范围：-55℃ 至 +150℃
三、核心特点
- 低正向压降：1A 工作点下 Vf≈1.25V，减小导通损耗，有利于提升效率并降低发热。
- 快速恢复：Trr≈38ns，相比传统慢恢复整流器件，开关过程中的反向恢复能量更小，适合中高速开关场合。
- 高耐压与低漏电：600V 的耐压配合微安级反向漏电，适配高压整流与阻断场景。
- 抗浪涌能力：60A 的单次浪涌能力能应对开机冲击与瞬态电流脉冲。
四、典型应用
- 开关电源整流（PRIMARY/SECONDARY）与续流二极管
- 适配器、充电器、高压电源的整流与保护
- 电机驱动与逆变器中的快速回复整流
- 电源防反接、钳位与浪涌吸收电路
- 工业和家庭电源管理系统
五、设计与使用建议
- 热管理：在 1A 连续工作时正向压降会产生明显功耗（P≈Vf×I），须在 PCB 布局上增加铜箔面积或散热路径以降低结温，避免长期高温应力。
- 开关兼容性：Trr=38ns 能显著降低开关损耗与电磁干扰，但在高频应用中仍需配合合适的缓冲与吸收网络（阻容、电感）以优化性能。
- 浪涌与峰值：Ifsm=60A 为非重复峰值，适用于短时浪涌，设计时应避免频繁接近该值以延长器件寿命。
- 焊接与封装：SMB 表面贴装便于自动化组装，建议按供应商推荐的回流温度曲线进行焊接，并遵循静电敏感器件的基本防护措施。
六、可靠性与环境适配
MURS160 的工作结温范围宽（-55℃～+150℃），适应工业级温度要求。在高温、高压和重复浪涌条件下仍能保持稳定工作，但推荐在长期应用中做热仿真与寿命评估，确保结温在安全范围内。
七、封装与标识
该器件采用 SMB（Surface Mount SMB）封装，便于表面贴装生产与自动化装配。器件标识与极性通常在本体上有环形或带状标记（以厂家铭刻为准），购买和使用时请以实物标注及厂商资料为准。
总结：DOWO MURS160 是一款面向高压整流与中速开关场景的低功耗快速恢复二极管，600V 耐压、1.25V 正向压降、38ns 反向恢复时间和 60A 峰值浪涌能力，使其在开关电源、适配器及工业电源保护中具有良好性价比与适用性。购买时请参考厂商详细数据手册以完成最终设计与可靠性评估。

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.
