二、主要参数

  1. 晶体管类型：PNP

    • 作为PNP型晶体管，BC857BTT1G在负载连接到正电源时表现优越，适用于开关和放大电路。

  2. 集电极电流最大值（Ic）：100mA

    • BC857BTT1G的集电极电流最大值为100mA，能够支持大部分需要较高输出电流的应用。

  3. 集射极最大击穿电压（Vceo）：45V

    • 最大集射极击穿电压为45V，这使得该元器件在高电压应用中具有良好的安全性，适合于电源管理和信号处理。

  4. 饱和压降（Vce_sat）：650mV at 5mA 和 100mA

    • 在较小的电流条件下（5mA和100mA），饱和压降为650mV，表明其在开关状态下的效率较高，能有效降低功耗。

  5. 集电极截止电流（ICBO）：15nA

    • 极低的截止电流特性使得该晶体管在长时间待机时依然保持较小的泄漏电流。

  6. 直流电流增益（hFE）：220 at 2mA，5V

    • 在较低的偏置电流下（2mA）能够提供高达220的电流增益，代表了良好的放大能力，特别适合于小信号放大器应用。

  7. 功率最大值：200mW

    • 最大功率为200mW，适配丰富的低功耗电路设计，确保其在低功耗和高效率条件下具有良好的工作表现。

  8. 频率跃迁：100MHz

    • 较高的频率特性使其适用于RF和高频信号处理，拓展了其应用范围。

  9. 工作温度范围：-55°C ~ 150°C

    • 宽广的工作温度范围，使得BC857BTT1G在极端环境下也能稳定工作，适用于汽车、航空和工业控制等场合。

三、封装和安装

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
