BSS138K 产品概述

一、产品简介

BSS138K是一款由安森美（ON Semiconductor）制造的N通道金属氧化物场效应管（MOSFET），其设计旨在满足多种电子应用的需求。凭借其优良的电气特性和适应广泛应用场景的能力，BSS138K在电子设备中广受欢迎，尤其是在开关和放大电路中表现卓越。

二、主要特性

  1. 电压与电流能力:

    • 漏源电压 (Vdss): 支持最高50V的漏极源极电压，使其适合用于中等电压环境。
    • 连续漏极电流 (Id): 在25°C时，BSS138K可承载最高220mA的漏极电流，适合多种条件下的直流电流应用。

  2. 导通电阻:

    • 在不同的栅源电压 (Vgs) 下，BSS138K的导通电阻 (Rds(on)) 最高可达1.6Ω (@ 50mA和5V)。较低的导通电阻意味着该MOSFET能在开启状态下提供更高效的电流流动，有助于减少功耗。

  3. 阈值电压:

    • BSS138K的栅源阈值电压 (Vgs(th)) 最大为1.2V (@ 250µA)，这意味着它能够在较低的电压下进入导通状态，提高了其在低电压电路中的应用宽度。

  4. 温度范围:

    • 该器件工作温度范围广泛，允许在-55°C到150°C之间稳定工作，适用恶劣环境下的应用，并确保产品的可靠性。

  5. 封装与安装方式:

    • BSS138K为表面贴装型（SOT-23-3），便于自动化安装，适合现代电子设备的紧凑设计需求。其小巧的TO-236-3、SC-59封装形式使得其适用于高密度电路设计。

  6. 输入电容和栅极电荷:

    • 该MOSFET在25V下最大输入电容 (Ciss) 限制为58pF，栅极电荷 (Qg) 则最大为2.4nC (@ 10V)，保证了其较快的开关速度和良好的高频性能，适合于高频开关应用。

三、应用场景

BSS138K的性能使其成为多种应用场景下的理想选择，包括但不限于：

  1. 开关电源:

    • 可在开关电源中作为转换器开关，帮助检测并控制电源流动，提高能效。

  2. 信号调理:

    • 在模拟信号处理应用中，可作为信号开关或缓冲器，确保信号的稳定和可靠性。

  3. 电池供电设备:

    • 由于其低导通电压和良好的高温性能，BSS138K无疑是电池供电设备及便携式设备中的一员，最大限度地节能。

  4. LED驱动电路:

    • 可用于LED驱动电路中的开关控制，保证LED 明亮而稳定的光输出。

  5. 汽车电子:

    • 在汽车应用中富有极高的可靠性，能够承受极端的温度并在长时间内稳定工作。

四、总结

综合来看，BSS138K是一款高性价比的N通道MOSFET，具备出色的电气特性和广泛的应用场景。无论是工业应用、消费电子还是汽车电子，BSS138K的稳定性和可靠性使其成为设计师和工程师的首选器件。它适应性能优越的特点，使其能够为现代电子设备提供高效、可靠的解决方案。

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
