BCM857BS-7-F 产品概述
产品简介
BCM857BS-7-F 是一种高性能 PNP 型双极晶体管(BJT),专为低功耗应用而设计,具有卓越的电气特性和广泛的工作温度范围。作为 DIODES(美台)品牌推出的一款主流产品,BCM857BS-7-F 是一款适用于各种电子电路的理想选择,尤其在开关和放大电路中表现卓越。
基本参数
BCM857BS-7-F 的额定功率为 200mW,适用于负载功率较小的应用场景。该晶体管的集电极电流(Ic)最大值为 100mA,集射极击穿电压(Vce)最高可达 45V,提供了充分的电压承受能力以满足大多数应用需求。在 Vce 饱和状态下,当 Ic 为 5mA 和 100mA 时,最大饱和压降为 400mV,这进一步证明了其在高效信号传输中的优越性能。
电气特性
BCM857BS-7-F 具备卓越的直流电流增益(hFE),在 5V 和 2mA 的工作条件下,最小值可达 220。这一特性使得晶体管在低输入电流下依然能够实现较强的输出能力,非常适合用于信号放大和开关应用。同时,其集电极截止电流(ICBO)低至 15nA,表明其具有良好的漏电性能,确保装置在静态状态下的可靠性和稳定性。
频率响应
该产品的频率响应高达 100MHz,适用于高频应用,特别是在通讯和信号处理领域表现突出。其良好的频率特性确保了在高频信号处理中对信号的清晰重现与高速响应能力,这对现代电子线路的设计至关重要。
工作温度范围
BCM857BS-7-F 具有宽广的工作温度范围,从 -65°C 到 150°C,适应于各种严苛环境应用的使用需求。该特性使此组件在工业、汽车及消费电子产品中表现出色,尤其适用于需要极端耐温特性的应用场景。
封装与安装
BCM857BS-7-F 采用 SOT-363 封装形式,这是一种表面贴装型(SMD)封装,方便在高密度电路板上的安装。小巧的尺寸使得其适用于空间受限的电子设备,同时减小整体电路的尺寸和重量,提升设计的灵活性。
应用领域
BCM857BS-7-F 广泛应用于多种电子电路,包括放大器和开关电路、信号处理单元、与电源管理相关的电路以及高频应用场合。在消费电子、工业控制和汽车电子领域都有着良好的应用前景。
总结
总体来看,BCM857BS-7-F 是一款集高效性能、可靠性和全面适应性的三极管。它凭借200mW 的额定功率、100mA 的集电极电流、45V 的击穿电压以及优良的频率特性,为现代电子设计提供了可靠的解决方案。无论在何种应用场景中,该产品均可提供稳定的性能和高效的电路设计选择,确保设计者在实现功能目标的同时,兼顾产品的耐用性和经济性。
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.
