  • 商品分类: 整流桥
  • 工作温度: -55℃ ~ +150℃ (Tj)
  • 整流电流: 8 A
  • 正向压降 (Vf): 1.1 V @ 8 A
  • 正向浪涌电流 (Ifsm): 300 A
  • 直流反向耐压 (Vr): 800 V

封装

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。

特性

高整流电流

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。

低正向压降

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。

高反向耐压

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。

低反向漏电流

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。

宽工作温度范围

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。

高浪涌电流能力

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。

应用场景

电源供应

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。

电机驱动

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

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。

汽车电子

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。

安装和使用注意事项

  • 散热: 为了确保长期可靠运行,建议在安装时考虑良好的散热措施,如使用散热片或安装在金属基板上。
  • 电气隔离: 确保在安装过程中保持良好的电气隔离,以防止短路或其他电气故障。
  • 工作条件: 在设计和安装过程中,必须确保工作条件符合产品规格,以避免过载或过温导致的故障。

总结

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。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
