产品概述：BC857BLT1G PNP型晶体管

基本信息

BC857BLT1G 是一种表面贴装式 PNP 晶体管，专为低功耗应用而设计，适合那些需要高灵敏度、低噪声和高增益的电路。其最大集电极电流 (Ic) 为 100mA，最大集射极击穿电压 (Vce) 为 45V，使其成为多种电子应用的理想选择。包装形式为 SOT-23-3 (TO-236)，确保其在空间受限的电路板上具有良好的适应性。

关键参数

  • 晶体管类型：PNP
  • 最大集电极电流 (Ic)：100mA
  • 最大集射极击穿电压 (Vce)：45V
  • 饱和压降 (Vce(sat))：当 Ib 为 5mA，Ic 为 100mA 时，最大饱和压降为 650mV。
  • 集电极截止电流 (ICBO)：最大为 15nA，体现出其优越的响应特性。
  • 直流电流增益 (hFE)：最小值为 220，这一高增益使得在各种应用中可有效放大信号。
  • 最大功率耗散：300mW
  • 频率响应：跃迁频率高达 100MHz，适合高频应用。
  • 工作温度范围：-55°C 到 150°C，保障其在极端环境下的可靠性。

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
