DESCRIPTION
Thanks to highly sensitive triggering levels, the UTC
US104S/N is suitable for all applications where the available gate
current is limited, such as motor control for hand tools, kitchen
aids, overvoltage crowbar protection for low power supplies,
Available in through-hole or surface-mount packages, they
provide an optimized performance in a limited space area.

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The device is guaranteed to meet performance specification within 0°C ~70°C operating temperature
range and assured by design from –20°C ~85°C.
