BC817-40 产品概述
概述
BC817-40是一款高性能的NPN型三极管，广泛应用于各类电子电路中，尤其在开关电源、音频放大器和信号放大器等领域中表现出色。它的设计旨在提供高效率和可靠性，满足现代电子设备对小型化和高性能的需求。本产品由合科泰（Hottech）品牌生产，采用SOT-23封装，便于在空间有限的电路中进行应用。
基本参数
BC817-40的主要性能参数如下：
- 功率（Pd）: 最大功率300mW，适合低功率应用。
- 直流电流增益（hFE@Ic,Vce）: 在集电极电流为100mA、集电极-发射极电压为1V的条件下，电流增益高达250，使其在增益要求较高的应用中表现出色。
- 特征频率（fT）: 频率响应达到100MHz，适合需要高频操作的应用。
- 集射极击穿电压（Vceo）: 最大集射极击穿电压为45V，提供较强的电压承受能力，适合多种工作环境。
- 集电极-发射极饱和电压（VCE(sat)@Ic,Ib）: 在集电极电流为500mA、基极电流为50mA时，饱和电压为700mV，表明其在开关状态时有良好的效率。
- 集电极截止电流（Icbo）: 集电极截止电流小于100nA，确保在关断状态下电流泄漏极小，提高了电路整体的能效。
- 集电极电流（Ic）: 最大集电极电流为500mA，支持较大的负载。
封装
BC817-40采用的是SOT-23封装，尺寸较小，非常适合现代紧凑型电路设计。这种封装的优势在于其低引脚电阻和引脚间距，能够有效减少布线时的复杂性和电阻。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
