NTE5554
Silicon Controlled Rectifiers (SCR) 400V 25A TO-220

See also >>> NTE5550 thru NTE5558

Description:
The NTE5550 thru NTE5558 SCR´s are designed primarily for half-wave AC control applications, such as motor controls, heating controls and power supply crowbar circuits.

Features:
- Glass Passivated Junctions with Center Gate Fire for Greater Parameter Uniformity and Stability.
- Small, Rugged, Thermowatt Constructed for Low Thermal Resistance, High Heat Dissipation and Durability.
- Blocking Voltage to 800 Volts
- 300A Surge Current Capability
