## Datasheet

📄 [Download PDF](https://novapart.co/datasheet/farnell:2723365/)

## **TN4015H-6I** 

## High temperature 40 A SCRs 

Datasheet - production data 

## **Applications** 

- Motorbike voltage regulator circuits 

- Inrush current limiting circuit 

- Motor control circuits and starters 

- Solid state relays 

## **Description** 

Thanks to its junction temperature Tj up to 150 °C, the device offers high thermal performances operation up to 40 A. It is fully tab insulated thanks to the ceramic inside the TO-220AB package and allows a back to back configuration. 

## **Features** 

- High junction temperature: Tj = 150 °C 

- High noise immunity dV/dt = 500 V/µs up to 150 °C 

- Gate triggering current IGT = 15 mA 

- Peak off-sate voltage 600 V VDRM/VRRM 

- High turn on current rise dI/dt = 100 A/µs 

- ECOPACK[®] 2 compliant component 

- Insulated package TO-220AB: 

   - Insulated voltage: 2500 VRMS 

- Complies with UL 1557 (File ref : E81734) 

Its trade-off noise immunity (dV/dt = 500 V/μs) versus its gate triggering current (IGT = 15 mA) and its turn-on current rise (dI/dt = 100 A/μs) allows to design robust and compact control circuit for voltage regulator in motorbikes and industrial drives, overvoltage crowbar protection, motor control circuits in power tools and kitchen aids, inrush current limiting circuits.
