DTC114ECA 是 MSKSEMI(美森科)推出的一款预偏置 NPN 小信号晶体管,采用 SOT-23 封装,面向逻辑接口驱动与小功率开关应用而设计。器件内部集成了基极限流电阻,便于直接由 TTL/CMOS/单片机 I/O 口驱动,简化外围电路布局。其工作温度范围广(-55℃ ~ +150℃),适用于工业级和车规级温度环境下的低功耗信号级切换场合。
注:上列数值为典型或保证测试条件下的数据。实际电路使用时应参考完整数据手册并根据实际环境与散热条件进行裕度设计。
DTC114ECA 采用 SOT-23 典型三引脚封装,体积小、易于贴装。器件的引脚通常为基极、集电极、发射极(具体引脚排列请参考厂方完整封装图与 PCB 布局指导)。在布局时建议:
DTC114ECA 是一款面向逻辑驱动与低功耗开关应用的预偏置 NPN 晶体管,结合 SOT-23 小封装与内部偏置电阻,能显著简化外围电路设计并提高系统集成度。其 50 V 的耐压能力、低饱和压降与工业级温度范围,适合在多种嵌入式与工业控制场景中使用。选择时请结合实际工作点、散热条件与输入驱动特性进行完整验证。若需更详细的电气特性曲线和封装机械尺寸,请参考厂方完整数据手册。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
