TIP122 产品概述

一、基本信息

型号: TIP122
类型: 达林顿管
封装: TO-220
制造商: CJ (江苏长电/长晶)
Vceo: 100V
Ic: 5A

达林顿管是一种双极型晶体管,具有高增益和高功率处理能力,广泛应用于各种电子电路中。TIP122是其中一种常见的达林顿管,因其独特的电气特性和结构设计,被广泛用于功率放大、开关电源、电机驱动及其他需要大电流的应用。

二、达林顿管的工作原理

达林顿管由两个NPN晶体管以特定方式串联组成。第一个晶体管的集电极与第二个晶体管的基极连接,这种配置使得输入基极电流得到进一步放大,最终输出集电极电流。因此,相较于单个晶体管,达林顿管可提供更高的电流增益。

TIP122是一个高性能的达林顿管,能够在较高Vce和Ic条件下稳定工作,其Vceo为100V,Ic为5A,这使得TIP122非常适合在高电压和高电流应用场景中使用。

三、应用领域

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
