STW12NK90Z 产品概述

基本信息

STW12NK90Z 是意法半导体(STMicroelectronics)推出的一款 N沟道金属氧化物半导体场效应管(MOSFET),其设计旨在满足高电压和高电流应用的需求。该器件具有优越的性能参数,使其适用于各种电源管理、开关和逆变应用。

关键参数

  • 漏源电压(Vdss): 900V

    • 这一参数表明该 MOSFET 能够承受最高 900V 的漏源电压,适合用于高压环境。
  • 连续漏极电流(Id): 11A (25°C 时)

    • 在标准环境温度(25°C)下,STW12NK90Z 能够提供高达 11A 的持续电流,这意味着它适合用于需要高电流管理的应用。
  • 栅源极阈值电压(Vgs(th)): 4.5V @ 100µA

    • 该 MOSFET 的开通电压为 4.5V,这使得其在低电压驱动下也能够快速导通与关断。
  • 漏源导通电阻(Rds(on)): 880mΩ @ 5.5A, 10V

    • 高效的导通特性使得其在应用中能够减少功耗,提高热效率。
  • 最大功率耗散: 230W (Tc)

    • 该参数表明该 MOSFET 能够在 25°C 的环境下承受高达 230W 的功率,适合用于高功率应用。
  • 工作温度范围: -55°C ~ 150°C

    • STW12NK90Z 具备宽广的工作温度范围,适合于恶劣环境及高温应用场合。

封装与安装

STW12NK90Z 使用 TO-247-3 封装,该封装设计不仅方便了散热,还便于通孔安装。这使得该器件在各种电路板设计中都具有良好的适应性,满足了不同应用的需求。

性能特点

  1. 高效能: 该 MOSFET 的导通电阻在数据中显示为 880mΩ,在高电流操作下表现出良好的低损耗特性,显著提升了能源的利用效率。

  2. 快速开关特性: 栅极电荷(Qg)为 152nC,这意味着 MOSFET 响应迅速,可在高频率开关应用中高效工作。此外,Vgs 的最大偏压为 ±30V,使得设计者在驱动电路时能灵活选择。

  3. 可靠性与耐用性: 该 MOSFET 的宽工作温度范围和高功率耗散能力使其在各种工业环境中都能稳定工作,且极大提升了设备的整体可靠性。

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
