NTE5442
Silicon Controlled Rectifier (SCR) 8A, 50V TO-127

See also >>>NTE5442 thru NTE5448

Description:
The NTE5442 thru NTE5448 are silicon controlled rectifiers (SCR´s) in a TO127 type package designed 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 regulators, vending machines, and lamp drivers.

Features:
- Small, Rugged Construction
- Practical Level Triggering and Holding Characteristics @ +25°C:
IGT = 7mA Typ
IHold = 6mA Typ
- Low “ON” Voltage: VTM = 1V Typ @ 5A @ +25°C
- High Surge Current Rating: ITSM = 80A

Note 1. NTE5446 is a discontinued device and is 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.
