DTA123YKAT146 产品概述

DTA123YKAT146 是由知名电子元器件制造商 ROHM(罗姆)公司推出的一款高性能数字晶体管,采用表面贴装型设计,适用于多种电子电路的需求。该产品在多个参数上表现出色,尤其是在低功耗、高开关频率及良好的电流增益方面,使其成为现代电子设备中不可或缺的组成部分。

关键参数

  1. 电流能力: DTA123YKAT146 的最大集电极电流(Ic)为 100mA,适合于各种低至中功率的应用场合。此外,驱动能力的可接受范围,包括最大集电极截止电流为 500nA,确保其能在极低功耗情况下保持高效工作。

  2. 工作电压: 该数字晶体管的最大集射极击穿电压为 50V,能够在较高电压的环境下稳定工作。这样的特性使其适合用于电源电路及其他需要承受高电压的应用。

  3. 饱和压降: 在不同的基极电流(Ib)和集电极电流(Ic)下,DTA123YKAT146 的 Vce 饱和压降最大值为 300mV(在500µA和10mA时),这意味着在工作状态下能够有效减少功耗,提升整体电路的能效。

  4. 电阻特性: 在其内部结构中,基极电阻(R1)被定义为 2.2 kΩ,而发射极电阻(R2)为 10 kΩ,这些电阻值使得该晶体管能够在给定的电压和电流下提供适当的增益,增强开关特性和频率响应。

  5. 增益特性: 根据不同的集电极电流和集射极电压,DTA123YKAT146 的直流电流增益(hFE)的最小值为 33(在10mA与5V时)。这个增益值特别适用于需要高增益的小信号应用,使其成为信号放大、开关、和其他控制电路的理想选择。

  6. 频率响应: 该晶体管能够支持高达 250MHz 的跃迁频率,对于高频应用极具吸引力。这使得 DTA123YKAT146 能够用于射频和高速数字电路中,满足现代通信和信息处理的需求。

  7. 功率处理: DTA123YKAT146 最大功率为 200mW,使其能够在多种应用环境下安全稳定地工作,适合包括信号调节、负载开关等场合。

应用场景

DTA123YKAT146 非常适合于多种应用场景,包括但不限于:

  • 数字电路:应用于各种数字逻辑电路中,作为开关元件。
  • 音频放大器:在小功率音频放大器中,用于信号的放大和调节。

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
