BFP840FESDH6327XTSA1 是英飞凌(Infineon)公司推出的一款高性能 NPN 型三极管,采用 TSFP-4-1 表面贴装封装,广泛应用于高频通信和无线设备。作为一款设计用于低噪声和高线性度的三极管,BFP840 在频率响应、增益和噪声系数等多个关键性能指标上表现优异,满足现代电子设备对性能的苛刻要求。
安装类型和封装: BFP840FESDH6327XTSA1 采用表面贴装型(SMD)设计,这一特性使得它在现代电路板设计中的安装更加便捷,适用于自动化生产线。封装为 TSFP-4-1,尺寸紧凑,便于节省电路板空间,同时保证了散热性能。
电流和功率性能: 此款三极管的最大集电极电流(Ic)为 35mA,最大功率为 75mW,这使得它在承受高负载的情况下仍能稳定工作。与此相应的,集电极-发射极击穿电压(Vce)最大值为 2.6V,确保其在电路设计时能够处理较低电压下的高电流应用。
频率特性: BFP840FESDH6327XTSA1 的跃迁频率高达 85GHz,显示了其在高频率应用中的优势。该特性使其非常适合用于需要快速信号切换和高带宽的应用,如射频放大器和毫米波信号处理。
增益和噪声性能: 增益(S21)达到 35dB,能够在增益对电路设计至关重要的情况下,提供卓越的信号放大能力。此外,在 5.5GHz 的操作频率下,噪声系数为 0.75dB,显示了出色的低噪声特性,使其非常适合于低噪声放大器(LNA)设计。这一特性对于现代通信系统中的信号接收部分显得尤为重要,能够有效提升信号质量。
工作温度和可靠性: 该三极管的工作温度最高可达 150°C(TJ),使其在极端环境条件下仍能保持良好的工作性能。这一点对于航天、汽车及工业应用尤为重要,能够确保设备在苛刻的工作环境中持续、稳定的运行。
直流电流增益: 在特定条件下(Ic = 10mA,Vce = 1.8V),BFP840的 DC 电流增益(hFE)最低值为 150。这一高增益特性使得它在设计中能够降低对多级放大的需求,简化电路设计,提高系统的可靠性和效能。
基于以上优越的性能指标,BFP840FESDH6327XTSA1 被广泛应用于以下领域:
综上所述,BFP840FESDH6327XTSA1 是一款集高增益、低噪声和宽频带于一体的高性能 NPN 三极管,适用于要求严格的现代通信和无线设备。凭借其可靠性和卓越的电气性能,BFP840 自投放市场以来受到了设计工程师的广泛关注与青睐,是当今电子元件市场中不可或缺的重要组成部分。无论是在传统的 RF 应用还是新兴的物联网设备中,BFP840FESDH6327XTSA1 都展现出其广阔的市场价值和应用前景。

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.
