    • 描述了在特定漏源电压下,栅极和漏极之间的电容。
  • 导通电阻(RDS(on)@Vgs, Id):80 mΩ @ 4.5 V, 3.6 A
    • 在指定的栅极电压和漏极电流下,MOSFET的导通电阻,这决定了设备在开启状态下的能量损耗。
  • 栅极电荷(Qg@Vgs):4 nC
    • 表示从栅极到源极的总电荷,这对驱动MOSFET的性能有重要影响。
  • 漏源电压(Vdss):18 V
    • 指定了MOSFET可以承受的最大漏源电压,超过此值可能导致设备损坏。
  • 类型:1个N沟道
    • 表明这是一个N沟道MOSFET,适用于各种开关和放大应用。
  • 输入电容(Ciss@Vds):300 pF @ 10 V
    • 描述了在特定漏源电压下,栅极和源极之间的输入电容。
  • 连续漏极电流(Id):3.6 A
    • 指定了MOSFET可以持续承受的最大漏极电流。
  • 阈值电压(Vgs(th)@Id):1.3 V @ 250 μA
    • 表示当漏极电流达到250 μA时,所需的最小栅极电压,这决定了MOSFET的开启阈值。

应用场景

SK2302AA 适用于以下几个应用场景:

  1. DC-DC 转换器:
    • 由于其低导通电阻和高效能,SK2302AA非常适合用于DC-DC转换器中的开关元件,帮助实现高效率的电源转换。

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
