TN1205H
High temperature 12 A SCRs
Datasheet − production data
Features
■High junction temperature: Tj = 150 °C
■Medium current SCRs
■High noise immunity up to 150 °C
■RoHS (2002/95/EC) compliant
■600 V VDRM, VRRM
Application
■General purpose AC line load switching
■Motor control circuits
■Small home appliances
■Lighting
■Inrush current limiting circuits
■Over-voltage crowbar protection
Description
Available in standard gate triggering levels, the
TN1205H SCR series has very high switching
capability up to junction temperature of 150 °C.
These products fit all modes of control found in
applications such as overvoltage crowbar
protection, motor control circuits in power tools
and kitchen aids, inrush current limiting circuits,
capacitive discharge ignition and voltage
regulation circuits.
These products are particulary adapted for use in
areas where the ambient temperature is high or
the ventilation low, or where an increase of power
density is required.
Through-hole or surface-mount packages provide
performance in a limited space area.
