BC846BHE3-TP 产品概述
一、器件简介
BC846BHE3-TP 为 MCC（美微科）提供的一款通用 NPN 双极型晶体管，采用 SOT-23 小封装，适用于小信号放大与低功率开关场合。器件在 Ic=2mA、Vce=5V 时直流电流增益 hFE≈200，允许集电极电流最高 100mA，集射极击穿电压 Vceo=65V，器件特征频率 fT≈100MHz，兼具较高增益与较好高频响应。
二、关键参数
- 晶体管类型：NPN（单个器件）
- 最大集电极电流 Ic：100mA
- 集射极击穿电压 Vceo：65V
- 功耗 Pd：225mW（典型环境下）
- 直流电流增益 hFE：200（2mA, 5V 条件下）
- 特征频率 fT：100MHz（典型）
- 集电极截止电流 Icbo：100nA（典型）
- 集电极饱和电压 VCE(sat)：约 500mV（典型）
- 发射-基极击穿电压 Vebo：6V
- 工作温度范围：-55℃ ～ +150℃
- 封装：SOT-23
- 品牌：MCC（美微科）
- 数量：1 个 NPN 器件
三、性能与特点
- 高 hFE：在小电流工作点下增益较高，适合前级放大及偏置电路。
- 宽电压余量：65V 的 Vceo 支持较大电压余量，在直流电源和负载变化情况下更稳健。
- 高频特性良好：fT≈100MHz，适合用于高频信号放大与快速开关。
- 小型封装：SOT-23 方便高密度 PCB 设计与自动化贴装。
- 宽温度范围：适应工业级温度需求，可靠性高。
四、典型应用场景
- 小信号放大器、前置放大与音频前级
- 逻辑驱动、低电流开关与电平转换
- 高速脉冲信号放大与信号整形
- 便携式与消费类电子中的小功率开关元件
五、使用建议与注意事项
- 封装功耗 Pd 与 PCB 散热密切相关，使用时应在设计阶段做好铜箔散热，并考虑环境温度和器件结温限制，必要时按厂家手册进行功耗降额计算。
- VCE(sat)≈500mV 为典型值，实际饱和电压与驱动基极电流、集电极电流有关，若用作开关应保证足够基极过驱动以降低饱和损耗。
- 引脚排列与封装细节请以厂方数据手册为准，布局时注意最短线路及地回流路径以减少寄生。
- 焊接遵循推荐回流曲线；避免长时间超温，防止器件老化。
- 做静电防护（ESD），在装配与测试环节使用防静电措施。
六、选型及替代建议
在需要同类性能的替代品时，可参考 BC846 系列或其它通用 NPN 小信号晶体管，但选型时务必核对 Vceo、hFE、Ic、Pd 与封装，确保满足电路的极限与热管理要求。更多细节请参阅 MCC 官方数据手册与典型应用电路。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
