BSS138 场效应管(MOSFET)产品概述

概要

BSS138 是一种由 MDD 品牌生产的 N沟道场效应管(MOSFET),采用 SOT-23 封装。这种小型化的 MOSFET 设计,非常适合用于各种需要高效能和紧凑布局的电子应用。

基本参数

以下是 BSS138 的一些关键参数:

  • 功率(Pd): 500 mW

    • 这表明该 MOSFET 在正常操作条件下可以承受的最大功率。
  • 反向传输电容(Crss@Vds): 1.5 pF @ 30 V

    • 这个参数反映了在特定漏源电压下,栅极和漏极之间的电容值,影响信号传输的速度和效率。
  • 导通电阻(RDS(on)@Vgs, Id): 1.1 Ω @ 4.5 V, 0.3 A

    • 当栅极电压为 4.5 V,漏极电流为 0.3 A 时,MOSFET 的导通电阻为 1.1 Ω。这是一个重要的参数,决定了 MOSFET 在导通状态下的能耗和热量生成。
  • 工作温度范围: -55 ℃ ~ +150 ℃

    • 这个广泛的温度范围使得 BSS138 可以在各种环境条件下稳定运行,从极寒到高温环境。
  • 栅极电荷(Qg@Vgs): 60 nC @ 10 V

    • 栅极电荷是指在特定栅极电压下,需要驱动 MOSFET 开启所需的电荷量。较低的栅极电荷意味着更低的驱动能耗。
  • 漏源电压(Vdss): 50 V

    • 这是 MOSFET 可以承受的最大漏源电压,确保在正常操作条件下不会因过压而损坏。
  • 类型: 1 个 N沟道

    • 作为一个 N沟道 MOSFET,它通过应用正栅极电压来控制电流流通。
  • 输入电容(Ciss@Vds): 23.8 pF @ 30 V

    • 输入电容是指在特定漏源电压下,栅极和源极之间的电容值,影响了开关速度和驱动需求。
  • 连续漏极电流(Id): 500 mA

    • 这是 MOSFET 可以连续承受的最大漏极电流,确保在长时间运行中不会过热或损坏。
  • 阈值电压(Vgs(th)@Id): 1.5 V @ 250 μA

    • 阈值电压是指当 MOSFET 开始导通时所需的最小栅极电压。在这里,当栅极电压达到 1.5 V 时,漏极电流将达到 250 μA。

应用场景

BSS138 因其小尺寸、低导通电阻和宽工作温度范围,非常适合以下应用:

  • 低功耗电子设备

    • 如便携式电子设备、无线传感器网络等,需要高效能和低能耗的场景。
  • 自动控制系统

    • 在工业自动化、机器人控制等领域,BSS138 可以作为高频开关元件,实现快速、可靠的信号控制。
  • 电源管理

    • 用于 DC-DC 转换器、电源开关等应用,利用其低导通电阻和高频开关能力来提高效率。
  • 汽车电子

    • 因其宽工作温度范围,适用于汽车电子系统中的各种控制和驱动应用。

优势

  1. 小尺寸封装

    • SOT-23 封装使得 BSS138 非常适合空间有限的设计,提高了 PCB 布局的灵活性。
  2. 低导通电阻

    • 低导通电阻(1.1 Ω)减少了能耗和热量生成,提高了系统整体效率。
  3. 宽工作温度范围

    • 从 -55 ℃ 到 +150 ℃ 的广泛温度范围,确保了在各种环境条件下稳定运行。
  4. 高频开关能力

    • 低输入电容和栅极电荷使得 BSS138 适合高频开关应用,提高了系统响应速度。

总结

BSS138 是一种高性能、紧凑化的 N沟道 MOSFET,通过其优异的参数和广泛的应用场景,成为现代电子设计中的一个理想选择。其低导通电阻、宽工作温度范围和小尺寸封装,使其在低功耗电子设备、自动控制系统、电源管理以及汽车电子等领域都有广泛的应用前景。

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
