NTE5621

TRIAC – 10 Amp

NTE Electronics 

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.
