  • 反向电流 (Ir): 500 μA @ 40 V
  • 商品分类: 肖特基二极管
  • 整流电流: 3 A
  • 正向压降 (Vf): 550 mV @ 3 A
  • 直流反向耐压 (Vr): 40 V

封装和外观

DSS34 采用 SOD-123 封装,这是一种小型化的封装形式,适合于空间有限的现代电子设备。SOD-123 封装具有良好的热性能和机械强度,能够满足各种应用场景下的需求。

电气特性

正向压降

DSS34 的正向压降为 550 mV @ 3 A,这意味着在通过该二极管的电流达到 3 A 时,仅会产生 550 mV 的电压降。这种低压降特性使得 DSS34 非常适合用于高效能的电源系统和功率电子设备中。

整流电流

该二极管的最大整流电流为 3 A,这使得它能够处理中等到较高的电流应用。这种高整流能力使得 DSS34 可以广泛应用于各种需要稳定和可靠电流整流的场景。

反向耐压

DSS34 具有 40 V 的直流反向耐压,这意味着在正常工作条件下,它可以承受高达 40 V 的反向电压而不会发生击穿或损坏。这种高耐压能力确保了设备在意外情况下也能保持稳定运行。

反向漏电流

在 40 V 的反向电压下,DSS34 的反向漏电流仅为 500 μA。这表明该二极管具有极低的漏电流,能够有效减少能量损耗和热量产生,从而提高系统的整体效率。

应用场景

DSS34 因其优异的电气性能和小型化封装,广泛应用于以下几个领域:

  1. 电源系统:

    • 作为整流二极管,用于交流到直流(AC-DC)转换。
    • 用于过滤和平滑电源输出。
    • 在开关模式电源(SMPS)中作为自由轮流二极管(Freewheeling Diode)。
  2. 功率电子设备:

    • 用于逆变器、变频器等设备中的电流整流和保护。
    • 在电机驱动系统中作为反馈二极管。
  3. 通信设备:

    • 用于通信设备中的电源模块和信号处理单元。
  4. 汽车电子:

    • 应用于汽车电子系统中的电源管理和保护模块。
  5. 工业控制系统:

    • 用于工业控制系统中的电源供应和信号处理部分。

优势

  • 低正向压降: 550 mV @ 3 A,提高系统效率,减少热量产生。
  • 高整流能力: 最大整流电流达 3 A,适合中等到较高电流应用。
  • 高耐压能力: 直流反向耐压达 40 V,确保设备在意外情况下稳定运行。
  • 小型化封装: SOD-123 封装,适合空间有限的现代电子设备。
  • 低漏电流: 反向漏电流仅为 500 μA @ 40 V,减少能量损耗。

使用注意事项

  • 确保安装时不超过最大允许的反向耐压和整流电流。
  • 避免在高温环境下使用超过推荐值。
  • 在设计时考虑到二极管的热管理,以确保长期可靠运行。

总结

DSS34 是一款性能优异、应用广泛的肖特基二极管。其低正向压降、高整流能力和高耐压特性,使其成为各种电子设备中的理想选择。通过选择 DSS34,设计师可以实现高效能、可靠性和小型化的电子系统。

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.

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
