NTE5442 thru NTE5448  
Silicon Controlled Rectifier (SCR)  
8 Amp  
Description:  
The NTE5442 thru NTE5448 are silicon controlled rectifiers (SCR’s) in a TO127 type package de-  
signed for high–volume consumer phase–control applications such as motor speed, temperature,  
and light controls, and for fast switching applications in ignition and starting systems, voltage regula-  
tors, vending machines, and lamp drivers.  
Features:  
D Small, Rugged Construction  
D Practical Level Triggering and Holding Characteristics @ +25°C:  
IGT = 7mA Typ  
IHold = 6mA Typ  
D Low “ON” Voltage: VTM = 1V Typ @ 5A @ +25°C  
D High Surge Current Rating: ITSM = 80A  
Absolute Maximum Ratings: (Note 1, TJ = +100°C unless otherwise specified)

Note 1. NTE5444 and NTE5446 are discontinued devices and are replaced by NTE5448.  
Note 2. Ratings apply for zero or negative gate voltage but positive gate voltage shall not be applied  
concurrently with a negative potential on the anode. When checking forward or reverse  
blocking capability, thyristor devices should not be tested with a constant current source in  
a manner that the voltage applied exceeds the rated blocking voltage.
