2SC1815L-GR-T92-B 产品概述

一、概览

2SC1815L-GR-T92-B 是 UTC(友顺)提供的一款通用 NPN 小信号三极管,适用于低功耗放大与开关场合。器件承受集电极电流最大 150mA,集—射极击穿电压 Vceo 为 50V,耗散功率 Pd 标称 625mW,封装为常见的 TO-92(2.54mm 引距),便于手工焊接与通用电路板布局。

二、主要电气参数

  • 晶体管类型:NPN
  • 最大集电极电流 Ic:150mA
  • 集—射极击穿电压 Vceo:50V
  • 耗散功率 Pd(注):625mW
  • 直流电流增益 hFE:700(典型,测试条件 2mA,Vce=6V)
  • 特征频率 fT:80MHz(适合中高频小信号放大)
  • 集电极截止电流 Icbo:100nA(低泄漏,利于低噪声电路)
  • 集—射极饱和电压 VCE(sat):250mV(标称,在 100mA, 10mA 条件下)
  • 发—基击穿电压 Vebo:5V

注:Pd 为器件在特定测试条件下的最大耗散,实际应用需按环境温度与散热条件做降额处理。

三、特点与优势

  • 高直流增益:在低电流工作点(2mA)下 hFE 可达 700,适合需要高增益的前置放大器与传感器信号放大。
  • 中高频性能:fT 约 80MHz,适用于音频到射频的中频段放大与开关。
  • 低漏电流与低饱和压:Icbo 低、VCE(sat) 低,有利于提高开关效率并降低静态功耗。
  • 通用封装:TO-92 外形便于手工装配与原型设计,适合教育、开发与小批量生产。

四、典型应用

  • 音频前置放大、MCU 的小信号驱动与接口电路;
  • 低功耗传感器放大、差分放大器和电平转换;
  • 低电压开关与驱动(注意 Vce、Ic 限制);
  • 振荡器、整流/稳压前级与通用放大模块。

五、封装与引脚

封装:TO-92(引距 2.54mm)。
常见 2SC1815 系列引脚排列(以平面朝向观察)为:左—发射极(E)、中—基极(B)、右—集电极(C)。不同厂商版本可能略有差异,具体型号引脚请以 UTC 官方封装图和样片为准。

六、设计与散热建议

  • 在设计时应考虑 Pd 与结温上升,TO-92 自身散热能力有限,长期工作建议将 Ic 保持在安全范围内(如小于 100mA),并避免 Vce 长时间接近最大值。
  • 需要连续较高功率时,可通过散热片、贴片铜箔或把器件固定在散热良好的基板上改善散热条件。
  • hFE 随 Ic、Vce 与温度有较大变化,精确偏置电路应在目标工作点上进行测试与调整。
  • 注意不要让基极承受超过 Vebo 指定的反向电压(5V),以免损伤结。

七、注意事项与订购信息

  • 在高增益应用中需防止自激,建议在输入/反馈回路加合适的频率补偿或阻尼。
  • 规格参数为典型或最大值,实际设计请以 UTC 的最终数据手册为准。
  • 产品型号:2SC1815L-GR-T92-B;品牌:UTC(友顺);封装:TO-92。若需样品、完整数据手册或大批量采购支持,请联系 UTC 授权代理或供应链渠道获取最新库存与技术资料。

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.

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
