DTC123JCA 产品概述

一、产品简介

DTC123JCA 是一款预偏置的 NPN 数字晶体管(Digital Transistor),由 YANGJIE(扬杰)生产,封装为常见的 SOT-23。器件内部集成了基极限流/偏置电阻,方便与微控制器或逻辑电平直接接口,省去外部基极电阻,适合空间受限的开关和驱动场合。

二、主要参数

  • 极性:NPN(预偏置)
  • 集射极击穿电压 Vceo:50 V
  • 集电极最大电流 Ic:100 mA
  • 功耗 Pd:200 mW(封装热限制,需注意热降额)
  • 直流电流增益 hFE:80(在 Ic=10 mA,VCE=5 V 条件下)
  • 输入高电平门限 VI(on):典型 1.1 V(在 VCC=5 V,输入电流 100 μA 条件)
  • 输入低电平最大 VI(off):0.5 V(关断状态上限)
  • 导通时输出压降 VO(on):约 0.3 V(在 Ic≈10 mA 条件)
  • 输入电阻:约 2.86 kΩ,内部分压比率约 26
  • 工作温度范围:-55 ℃ ~ +150 ℃

三、性能特点

  • 预偏置设计:内置基极电阻,直接与 MCU/逻辑电平相连,简化外围电路,节省 PCB 空间与元件成本。
  • 低压降开关:在中等电流(例如 10 mA)下 VCE(sat) 约 0.3 V,有利于减小功耗和发热。
  • 宽温度与电压余量:50 V 的击穿电压和 -55~+150 ℃ 的工作温度,适合工业类环境。
  • 适中增益:hFE≈80 在常用工作点可保证可靠的开关放大能力。

四、典型应用

  • MCU/逻辑电平到负载的直接驱动(指示灯、低功耗继电器驱动的前级)
  • 开关型负载:小信号电机、继电器线圈的驱动前端(注意电流/功耗限制)
  • 电平转换与缓冲:将微控制器 IO 扩展为更强的下游开关能力
  • 工业控制与消费电子中常见的低功耗开关场景

五、使用建议与注意事项

  • 功耗与散热:Pd=200 mW 是封装级别下的额定耗散,实用中请考虑环境温度与 PCB 散热(铜箔面积、热 vias 等)进行热降额,避免长期靠近最大功耗工作。
  • 电流限制:不要超过 Ic=100 mA 峰值,连续工作时建议留裕量以降低发热和应力。
  • 驱动条件:输入高、低阈值表明可直接由 3.3 V 或 5 V MCU 驱动,但在边界电压下请验证开关可靠性。
  • 反向与浪涌:驱动感性负载时务必加续流二极管或其它抑制措施,防止反向尖峰损伤器件。
  • 封装与焊接:SOT-23 适合自动贴片与回流焊,注意回流曲线与焊接工艺对可靠性的影响。

六、封装与采购信息

  • 品牌:YANGJIE(扬杰)
  • 数量:单个封装可选,适合小批量装配与批量采购
  • 封装:SOT-23,便于高密度 PCB 布局与自动化装配

总结:DTC123JCA 以其预偏置的便捷性、适中的导通特性和良好的电压/温度余量,适合用于需要直接由逻辑电平驱动的小功率开关场景。选型时请综合考虑工作电流、功耗与热管理,确保在安全区间内长期稳定工作。若需更详细的引脚定义、典型电路和完整电气特性,建议参照厂商完整数据手册或向供应商索取样片测试。

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
