Thyristors
logic level for RCD/ GFI/ LCCB applications
GENERAL DESCRIPTION
Glass passivated, sensitive gate
thyristors in a plastic envelope
suitable for surface mounting,
intended for use in Residual Current
Devices/ Ground Fault Interrupters/
Leakage Current Circuit Breakers
(RCD/ GFI/ LCCB)
applications
where a minimum I
GT
limit is needed.
These devices may be interfaced
directly to microcontrollers, logic
integrated circuits and other low
power gate trigger circuits.

Although not recommended, off-state voltages up to 800V may be applied without damage, but the thyristor may
switch to the on-state. The rate of rise of current should not exceed 15 A/µs.
