基本信息
DTC144EMT2L 是一款由知名半导体制造商 ROHM(罗姆)出品的数字晶体管,采用表面贴装型(SMD)设计,封装形式为 VMT3(SOT-723)。该产品专为低功耗、高效率应用设计,其额定功率为 150mW,具有出色的电气性能,适合用于各种电子设备中,如开关电路和信号处理应用。
电性能参数
DTC144EMT2L 的主要电气参数包括最大集电极电流 Ic 为 30mA,集射极击穿电压 Vce 最大值为 50V。这使得该晶体管能够在较高电压范围内工作,适合用作开关和放大器等应用。其集电极截止电流最大值仅为 500nA,显示出该器件的低功耗性能及良好的关断特性。
对于设计者而言,DTC144EMT2L 的 DC 电流增益(hFE)是一个重要的性能指标,在特定工作条件下,晶体管的增益最小值为 68(在 5mA 的集电极电流和 5V 的 Vce 条件下)。该增益值确保了在低输入信号下依然能够实现有效的信号放大,便利于多种电子电路设计需求。
饱和压降与响应频率
在大多数应用中,晶体管的饱和压降是性能的重要标准。DTC144EMT2L 在较小的输入电流条件下(500µA 的基极电流和 10mA 的集电极电流)具有最大饱和压降 300mV,表明其在开关状态下的效率很高,损耗较小。此外,该器件的跃迁频率达到 250MHz,表明其在高频应用中同样表现良好。这一特性使得 DTC144EMT2L 特别适合于高频数字电路和射频(RF)应用。

Request for quote
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.
