KBU808 是由 MDD 品牌生产的高性能整流桥元器件,适用于各种需要高效、可靠的电流整流应用。以下是对 KBU808 的详细介绍,包括其关键参数、特性和应用场景。
KBU808 采用 KBU 封装,这是一种常见的整流桥封装形式,设计用于提供良好的散热性能和机械强度。KBU 封装适合于各种工业和商用应用,尤其是在空间有限但需要高功率处理能力的情况下。
KBU808 支持高达 8 A 的连续整流电流,这使得它非常适合用于需要处理较大电流的应用,如电源供应、电机驱动和工业控制系统。
在 8 A 的工作条件下,KBU808 的正向压降仅为 1.1 V。这意味着在整流过程中能量损失较小,从而提高系统的整体效率和可靠性。
该元器件具有 800 V 的直流反向耐压,这使得它能够在高压环境中稳定运行,确保系统安全和可靠。
在 800 V 的反向电压下,KBU808 的反向漏电流仅为 10 μA。这表明该元器件具有优异的绝缘性能和低能耗特性。
KBU808 可以在 -55℃ ~ +150℃ 的广泛温度范围内工作,这使得它适用于各种极端环境下的应用,如汽车电子、工业自动化和航空航天等领域。
该元器件能够承受高达 300 A 的正向浪涌电流,这对于处理瞬时高电流冲击具有重要意义,提高了系统的抗干扰能力和可靠性。
KBU808 常用于各种电源供应系统中,如开关模式电源(SMPS)、直流-直流转换器(DC-DC)和线性电源等。其高整流电流和低正向压降特性使得它成为这些应用中的理想选择。
在电机驱动系统中,KBU808 可以作为桥式整流器或半桥式整流器的一部分,用于将交流电转换为直流电,为电机提供稳定的驱动电源。
工业控制系统中经常需要处理高电流和高压信号,KBU808 的高整流电流和高反向耐压能力使其成为这些系统中的关键组件。
由于其宽工作温度范围和高可靠性,KBU808 也广泛应用于汽车电子系统,如启动系统、照明系统和其他需要高性能整流器的应用场景。
KBU808 是一款高性能整流桥元器件,具有优异的电气特性和广泛的适用性。其高整流电流、低正向压降、宽工作温度范围以及高反向耐压能力,使其成为各种工业和商用应用中的理想选择。通过正确的安装和使用,KBU808 可以提供长期稳定可靠的服务。
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.
