BSS84-7-F 产品概述
一、产品简介
BSS84-7-F是一款高性能的P沟道场效应管(MOSFET),由DIODES半导体公司出品,其设计目标是为了提供可靠且高效的开关和线性调节应用。该元件在电子设备中广泛应用,特别适用于需要良好控制电流的场合,如电源管理、开关电路和模拟信号处理等。
二、关键参数
漏源电压(Vdss): 该产品的最大漏源电压为50V,这使其适合用于中等电压应用,能够有效地承受电源电压的波动,而不引起击穿。
连续漏极电流(Id): BSS84-7-F在25°C环境下的最大连续漏极电流为130mA。这一参数决定了它在电路中的载流能力,对于大多数低功率应用而言,这是一个足够的电流范围。
栅源极阈值电压: 此元件的栅源极阈值电压为2V @ 1mA,意味着其可以在低电压下有效启动,符合低功耗电路的需求。
漏源导通电阻(Rds(on)): BSS84-7-F的导通电阻在100mA、5V条件下最大为10Ω。低的导通电阻确保了在开启状态下的电流损耗较小,从而提高了电源的效率。
功率耗散: 最大功率耗散能力为300mW(在25°C环境下),说明该元件能够在较高负载下稳定工作,具有良好的热管理能力。
工作温度范围: BSS84-7-F的工作温度范围从-55°C到150°C,适用于各类严格的环境条件,特别是在温度变化较大的应用场合。
封装及尺寸: 该元件采用SOT-23封装,具有紧凑的尺寸和适合表面贴装的设计,方便在密集的电路板上进行安装。
三、应用领域
BSS84-7-F适用于各种电子设备,尤其是在以下场合具有显著优势:
电源管理: 可用作电源开关和调节器,控制电压和电流,确保电路稳定运行。
模拟电路: 应用在电子开关、负载开关以及模拟信号切换等场合,具有较低的信号失真率。
便携式设备: 由于其低阈值电压和相对较小的封装,BSS84-7-F非常适合于电池供电的设备,提升了产品的续航能力和效率。
LED驱动: 在LED驱动电路中发挥重要作用,能够控制LED的开启与关闭,提升光源的效率与使用寿命。
四、设计优势

宽工作温度范围: 产品能够在极端温度下稳定工作,使其在不同的工业及消费应用中均能出色表现。
小型封装: SOT-23封装对于现代电子设备尤为重要,有助于节省空间并提高集成度。
五、总结
综上所述,BSS84-7-F是一款高效、可靠且应用广泛的P沟道MOSFET,非常适合中低功耗的电子产品设计。其优良的性能特点及设计灵活性,使其成为固态开关、功率管理及模拟电路中的理想选择。对于寻求高效率和稳定性的工程师而言,BSS84-7-F无疑是一个理想的元件选择。
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.
