NTE5621 thru NTE5627
TRIAC – 10 Amp
Description:
The NTE5621 through NTE5627 TRIACs are designed primarily for full–wave AC control applica-
tions, such as light dimmers, motor controls, heating controls, and power supplies; or wherever full–
wave silicon gate controlled solid–state devices are needed. TRIAC type thyristors switch from a
blocking to a conducting state for either polarity of applied anode voltage with positive or negative gate
triggering.
Features:
D All Diffused and Passivated Junctions for Greater Parameter Uniformity and Stability
D Small, Rugged, Thermopad Construction for Low Thermal Resistance, High Heat Dissipation
and Durability.
D Gate Triggering Guaranteed in Two Modes
Absolute Maximum Ratings:
Repetitive Peak Off–State Voltage (TJ = +100°C, Note 2), VDRM

Note 1. NTE5622 and NTE5627 are discontinued devices and no longer available.
Note 2. Ratings apply for open gate conditions. Thyristor devices shall not be tested with a constant
current source for blocking capability such that the voltage applied exceeds the rated block-
ing voltage.
Note 3. Torque rating applies with use of torque washer. Mounting torque in excess of 8 in. lbs. does
not appreciably lower case–to–sink thermal resistance. Anode lead and heatsink contact
pad are common.
Note 4. For soldering purposes (either terminal connection or device mounting), soldering tempera-
tures shall not exceed +230°C.
