2SC4081UBTLR 产品概述
概述: 2SC4081UBTLR 是一款高性能的 NPN 型三极管 (BJT),特别设计用于各种低到中功率的电子电路中。作为 ROHM(罗姆)公司的一款产品,该器件具有优越的电气特性和可靠的性能,适用于广泛的工业和消费电子应用。其卓越的频率特性和高集电极电流,使得 2SC4081UBTLR 成为多种电路设计的理想选择,尤其是在对信号放大、开关、驱动器等功能有需求的设备中。
基础参数: 该三极管的集电极电流 (Ic) 最大值为 150mA,能够处理适度的负载。此外,其集射极击穿电压(Vce 耐压)最高可达 50V,这使得 2SC4081UBTLR 可以在多种工作环境中安全工作,提供了良好的电源管理模式。同时,该器件在工作过程中具有非常低的集电极截止电流(ICBO),最大值仅为 100nA,确保了在关断状态下的低功耗运行,适合于高效能应用。
饱和压降和增益特性: 2SC4081UBTLR 当基极电流 (Ib) 为 5mA 和 50mA 时,其 Vce 饱和压降最大为 400mV。这一低饱和压降值是该器件在开关状态时能有效降低功耗的关键特性之一。此外,在小信号条件下,其 DC 电流增益(hFE)最小为 120(在 1mA,6V 的工作条件下),从而保证了良好的信号放大能力和电流控制能力。这一高增益特性使其在多种应用中都能实现高效的驱动性能与信号处理。
频率响应与功率管理: 2SC4081UBTLR 的频率跃迁特性为 180MHz,适用于高速开关和信号放大的应用。这一特性对于当前许多要求高频信号处理的电子设备(如无线通信、音频处理等)至关重要。最大功率额定值为 200mW,意味着该三极管能够在各类应用中有效地管理功耗,将其用于温度和能量密集型工作环境时亦可高效运行。
高温工作能力: 2SC4081UBTLR 的工作温度范围高达 150°C(TJ),使其能够适应严苛的工作环境。这种高温适应性使得该器件在高温或高能耗应用中(例如汽车电子、工业设备等)具有更强的可靠性和耐用性,保证长期稳定操作。
封装和安装: 该三极管采用 SC-85(或 UMT3F)表面贴装封装,这一封装结构的小型化使得 2SC4081UBTLR 在现代电子设计中具有更高的灵活性与适配能力,可以轻松集成到紧凑的电路板设计中,方便实现更小型化和高密度的电路设计需求。
应用场景: 2SC4081UBTLR 广泛适用于开关电源、电子开关控制、音频放大、信号调理、无线通讯以及其他对信号线性放大和开关性能有需求的应用场合。从消费电子产品到工业控制设备,2SC4081UBTLR 不仅能够提供高效能的解决方案,同时也为设计工程师提供了更多的设计灵活性。
总结: 作为一款高性能 NPN 三极管,2SC4081UBTLR 凭借其卓越的电气性能、广泛的应用适用性和高温工作能力,成为当前市场上一款极具竞争力的半导体元件。ROHM 公司专注于提供高质量的电子元器件,2SC4081UBTLR 的推出继续印证了其在高性能半导体领域的领导地位,充分满足了现代科技日益增长的性能需求。无论是在设计阶段还是实际应用中,2SC4081UBTLR 的特点和优势令人印象深刻,值得广泛应用与推广。
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.
