BC857,215 产品概述
一、产品简介
BC857是一个高性能的PNP型双极性晶体管（BJT），广泛应用于各种电路设计中。这款晶体管由Nexperia（安世）制造，采用TO-236AB的小型封装（又称为SOT-23），具有卓越的电性能，适用于低功耗电子设备、信号放大、开关应用及其他多种用途。
二、基本参数
- 工作电流（Ic）：最大集电极电流为100mA，适合低功耗应用。
- 电压规格（Vce）：集射极击穿电压的最大值为45V，确保在合理的供电范围内工作，适合多种电源电压。
- 饱和压降（Vce(sat)）：在5mA和100mA的集电极电流下，Vce的饱和压降最大为650mV，这意味着在开关特性方面具有很好的性能，确保能有效降低功耗。
- 截止电流（ICBO）：最大集电极截止电流为15nA，表明在关断状态下具有极低的泄漏电流，提高了电路的整体效率。
- DC电流增益（hFE）：在2mA和5V的条件下，最小增益为125，适合中等增益要求的电路。
- 最大功率（Ptot）：250mW的最大功率额定值，确保在多种条件下可靠工作。

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.
