NTE5424  
Silicon Controlled Rectifier (SCR)  
for TV Power Supply Switching  
Description:  
The NTE5424 is a silicon controlled rectifier (SCR) in a TO220 type package designed for high–speed  
switching applications such as power inverters, switching regulators, and high–current pulse applica-  
tions. This device features fast turn–off, high dv/dt, and high di/dt characteristics and may be used  
at frequencies up to 25kHz.  
Features:  
D Fast Turn–Off Time  
D High di/dt and dv/dt Capabilities  
D Shorted–Emitter Gate–Cathode Construction  
D Low Thermal Resistance  
D Center–Gate Construction

Note 1. These values do not apply if there is a positive gate signal. Gate must be open or negatively  
biased.  
Note 2. Any product of gate current and gate voltage which results in a gate power less than the max-  
imum is permitted.
