2SC2881-Y (TE12L, ZC) 产品概述

一、产品概况

2SC2881-Y 是东芝(TOSHIBA)推出的一款 NPN 型双极结晶体管,采用 SC-62-3(等同 TO-243AA)小型封装。器件额定集电极电流 Ic 可达 800mA,集—射极击穿电压 Vceo 为 120V,适合需要中高压耐受且频率性能良好的放大或开关场合。典型直流电流增益 hFE 在 100mA、Vce=5V 时约为 120,特征频率 fT 约 120MHz,适用于 VHF/中频放大级和驱动级应用。

二、主要性能参数

  • 晶体管类型:NPN BJT
  • 最大集电极电流 Ic:800mA(峰值规范)
  • 集—射极击穿电压 Vceo:120V
  • 耗散功率 Pd:500mW(器件级,受封装与散热条件限制)
  • 直流电流增益 hFE:典型 120 @ Ic=100mA, Vce=5V
  • 特征频率 fT:120MHz(高频增益截止)
  • 集电极截止电流 Icbo:100nA(低漏电流,利于高阻态精度)
  • 集电极饱和电压 VCE(sat):约 1V(饱和时需足够基流)
  • 封装:SC-62-3(小型塑封,适合密集布板)

三、典型应用场景

  • 小信号至中功率放大器(VHF/中频级)
  • 驱动/缓冲级电路(继电器驱动、功率 MOSFET 驱动前级)
  • 低功耗开关电路与脉冲应用(需注意平均耗散限制)
  • 工业控制与通信终端中要求高耐压与中等频率响应的场合

四、设计与使用建议

  • 功率与散热:器件 Pd 标称为 500mW,属于小功耗等级。尽管 Ic 峰值可达 800mA,但持续大电流工作会因 VCE*Ic 导致过热。设计时应确保在允许的功耗范围内工作,必要时采用外部散热或限制占空比的脉冲驱动。
  • 饱和驱动:满足 VCE(sat) ≈ 1V 时,需提供足够基极电流。一般按饱和放大系数(forced β)取 5–10 进行基流设计,以保证快速进入饱和并降低 VCE(sat)。
  • 放大应用:hFE 在中等电流点表现良好,适合共射小信号放大。若用于高频放大,应考虑 fT=120MHz 的频率响应及相应的负反馈/偏置网络。
  • 漏电与偏置:Icbo 约 100nA,低漏电特性有利于高阻态偏置稳定性,但高温下漏电会升高,偏置网络应留有裕量。
  • 封装限制:SC-62-3 为小体积塑封,焊接热循环与机械应力敏感。具体引脚排列与焊接工艺请参阅东芝原厂封装图与回流曲线。

五、封装与订购信息

  • 品牌:TOSHIBA(东芝)
  • 型号:2SC2881-Y(代码 TE12L, ZC 可用于批次/包装区分)
  • 封装:SC-62-3(TO-243AA 相容小型塑封)
    请在采购或设计前以原厂最新数据手册为准,确认引脚定义、最大额定值与温度曲线。

六、可靠性与装配注意

  • 建议按东芝规定的回流焊温度曲线进行焊接,避免超温或过长期加热;表面贴装与通孔板间的热传导差异也会影响 Pd。
  • 器件有一定静电敏感性(ESD),在取放、存储与装配时做好防静电措施(腕带、接地台面、抗静电包装)。
  • 长期高温或接近最大额定值运行会降低寿命,关键产品建议做加速寿命试验或留足裕度。

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.

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
