在现代电子电路中,场效应晶体管(FET)因其高输入阻抗、低功耗和良好的热稳定性而受到广泛应用。MMBFJ113 是一款 N 通道的结型场效应晶体管(JFET),它设计用于各种低功耗、高灵敏度的应用场合。该器件特别适用于音频放大器、信号处理和开关电路等场景。本文将对 MMBFJ113 的基本参数、特性、应用和优势进行详细介绍。
电阻 RDS(On): 该器件的 RDS(On) 为 100 Ohms,表示在导通状态下的沟道电阻。这一参数决定了流经元件的电流和生成的功耗,较低的 RDS(On) 有助于降低功耗。
安装类型: MMBFJ113 采用表面贴装型(SMD)设计,便于现代电子设备的自动焊接和小型化.
工作温度范围: 器件可在 -55°C 到 150°C 的温度范围内正常工作,使其适用于极端环境下的应用。
漏极电流 (Idss): 在 Vds=15V 和 Vgs=0V 的条件下,漏极电流最大为 2mA。这一特性使得 MMBFJ113 能够在较高的压差下工作,同时仍保持适当的电流输出。
截止电压 (VGS off): 当 Vgs 逐渐增大到 500mV 时,漏极电流会降至 1µA。这表明该器件在关闭状态下的漏电流非常低,有助于减少待机功耗。
击穿电压 (V(BR)GSS): 器件的 V(BR)GSS 为 35V,确保在高压应用下能够承受一定的逆向电压。
最大功率: 最大功耗可达到 350mW,能够满足大多数小功率应用的需求。
封装类型: MMBFJ113 提供 SOT-23-3 封装,这是一种常见的小型表面贴装封装,适合多种电路布置。
高输入阻抗: MMBFJ113 的高输入阻抗可有效隔离前级电路,降低信号损失,适用于高灵敏度的信号放大应用。
低噪声性能: 该配件的设计确保了较低的噪声系数,使其在音频和信号处理应用中表现优异。
宽工作温度范围: 从 -55°C 到 150°C 的工作温度范围,确保了在极端环境中的可靠性,同时可用于汽车电子和工业控制等领域。
MMBFJ113 适用于广泛的应用,包括但不限于以下几种场景:
音频放大器: 由于其低噪声特性,适合用于高保真音频设备中的信号放大单元。
无线电频率放大器: 在无线电和通信设备中,用作高频信号的低噪声放大器。
传感器应用: 在各种传感器应用中,MMBFJ113 用于放大微弱的传感信号,例如温度传感器、光电传感器等。
开关控制: 由于其出色的导通和截止特性,该 FET 可以用于开关电路中,控制其他电路的工作状态。
MMBFJ113 是一款性能优异的 N 通道 JFET,凭借其低功耗、高输入阻抗及宽温度适应性,使其成为各种电子产品、信号处理方案及传感器应用的理想选择。ON (安森美) 作为该器件的制造商,为其提供可靠的质量保证,使得 MMBFJ113 在市场上受到广泛欢迎。无论是在消费电子、工业控制还是汽车电子等领域,MMBFJ113 的多功能性和高性能都得到了充分的体现。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
