DTC113ZCA 产品概述

DTC113ZCA 是一款预偏置(数字)NPN 晶体管,适用于直接由逻辑电平驱动的小功率开关场合。器件由 YANGJIE(扬杰)提供,封装为 SOT-23,兼具集成基极限流和基极下拉功能,便于简化外围电路设计。

一、主要参数与性能亮点

  • 集-射极击穿电压 Vceo:50 V
  • 最大集电极电流 Ic:100 mA
  • 功耗 Pd:200 mW(SOT-23,注意热限)
  • 直流电流增益 hFE:33(条件 10 mA,VCE=5V)
  • 最大输入关断电压 VI(off):300 mV(保证截止)
  • 输出饱和电压 VO(on):约 300 mV(测试条件 Ic=10 mA,亦在低电流 0.5 mA 时给出参考)
  • 内置输入电阻(基极限流)约 1.3 kΩ,内置基极下拉/放电电阻与限流电阻比约 12(用于防止漂浮)
  • 工作温度范围:-55 ℃ ~ +150 ℃

二、功能与内部结构说明

DTC113ZCA 为“数字晶体管”,内部集成了一只限流电阻(Rb ≈ 1.3 kΩ)与一只并联到发射极的下拉电阻(比例约为 1:12),因此可直接由 MCU 或 TTL/CMOS 输出端驱动而无需外接基极电阻。VI(off)=300 mV 表示输入低电平低于此值可确保器件处于截止状态,方便数字接口兼容。

三、典型应用场景

  • MCU/逻辑电平直接驱动的小信号开关(LED、指示灯)
  • 低电流继电器/小型电磁阀驱动(需考虑额定电流与功耗)
  • 电平转换、脉冲驱动、信号整形与开集电极输出替代方案
  • 作为下拉/上拉驱动的保护缓冲单元

四、使用要点与热管理建议

  • 虽然 Ic 最大标称为 100 mA,但在 SOT-23 且 Pd=200 mW 的条件下,不建议长期在高电流和高 VCE 下工作。功耗 P = VCE × Ic,应保证在最大功耗内并考虑环境温度与封装热阻的降额。
  • 例如在饱和状态(VCE≈0.3 V)开关 10 mA 时,耗散非常小;但若 VCE 较高(如开漏用于大负载),应核算功耗并避免接近 200 mW 极限。
  • 驱动能力:以 hFE≈33(10 mA)估算,驱动 10 mA 集电极电流所需基极电流约 0.3 mA。内部 Rb≈1.3 kΩ,5 V 输入时可提供足够基极驱动电流,但在驱动接近 100 mA 时需谨慎(基极电流及热耗限制)。

五、接线与典型电路

  • 常见低侧开关:负载一端接 VCC,另一端接到器件集电极,发射极接地,输入端接 MCU GPIO。器件在输入高电平时导通,将负载拉低。
  • 避免在高压大电流应用中将开关长期工作在线性区,优先工作于饱和/截止切换以降低功耗。

六、封装与选型提示

  • SOT-23 小封装适合空间受限电路板,但散热能力有限。若应用需要长时间大电流或较高 VCE,应选择更大功耗或带散热的器件。
  • 选型时关注:工作电压、最大集电极电流、功耗余量、逻辑兼容性(VI(off) 与输入阈值)及工作温度范围(-55~+150 ℃ 满足工业级需求)。

总结:DTC113ZCA 为一款易于直接由数字信号驱动的预偏置 NPN 晶体管,适合中低功率开关场合,使用时应特别注意功耗与热降额,合理安排工作点即可获得可靠的开关性能。

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
