MBR0520LT1G 是一款高性能肖特基二极管,由安森美半导体(ON Semiconductor)公司制造。该元器件充分利用了肖特基二极管的特性,在低正向压降和快速恢复能力方面表现出色,使其在各种应用中具有多种优势。其主要参数包括直流反向耐压(Vr)为20V,平均整流电流(Io)可达500mA,正向压降(Vf)为385mV(在500mA下测试),反向泄漏电流在20V时为250µA,适合那些需要高效率和快速开关特性的电路设计。
直流反向耐压(Vr):该二极管的最大直流反向耐压为20V,能够承受较高的工作电压,对于需要较高电压稳定性的应用尤为重要。
平均整流电流(Io):最大平均整流电流可达500mA,适合许多中等功率电子设备。该特性使其能够在多种电子电路中有效工作。
正向压降(Vf):正向压降为385mV(在500mA时),这一较低的压降使得设备在运行时能量损耗更小,从而提高了整个电路的效率,尤其在电源管理、电池充电等场合。
反向泄漏电流:在20V的条件下,与传统硅二极管相比,MBR0520LT1G 的反向泄漏电流(250μA)显著更低,这意味着在高温环境中,其性能依然稳定,降低了电源系统的功耗。
速度性能:具备快速恢复特性,恢复时间小于等于500ns,尤其适合高频率开关电源设计和快速脉冲应用,能够有效提高电源转化效率和稳定性。
MBR0520LT1G 采用SOD-123封装,具有小型化、节省空间的优势,适合于表面贴装应用,广泛应用于移动设备、便携式电子产品、家电、通信设备及工控设备等诸多领域。该封装设计不仅有助于提高生产效率,同时也便于设备的热管理。
该肖特基二极管的工作温度范围为-65°C到125°C,提供了极大的灵活性,可适用于各种恶劣工作环境。这种类型的工作温度性能对于工业应用至关重要,无论是在寒冷的环境还是在高温条件下,它均能够保证稳定工作。
MBR0520LT1G 主要应用于以下领域:
开关电源(SMPS):凭借其高效率和快速恢复能力,特别适用于开关电源中的逆变器和整流电路。
电池充电器:由于其低正向压降和低反向泄漏流,适用于移动设备的电池充电器设计,有利于提高充电效率。
直流-直流转换器:在DC-DC转换器中,作为整流二极管使用,能够有效提升转换效率。
LED驱动电路:在LED驱动电路中,可以降低光源损耗,提高整体发光效率。
MBR0520LT1G 是一款非常出色的肖特基二极管,凭借其低正向压降、低反向泄漏电流和快速恢复特性,成为各种电子电路设计中的理想元件。无论是在手机、平板电脑,还是在各类电源管理和LED驱动应用中,MBR0520LT1G 都能够提供优异的性能,满足现代电子产品对效率与可靠性的要求。安森美(ON Semiconductor)以其稳健的技术背景和广泛的产品线,确保了该元件能在激烈的市场竞争中立足并继续发挥重要作用。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
