This state-of-the-art solid-state relay
is designed for use in AC power
switching applications. The output is
rated for 1A at 250 Vrms and can
operate from 40 to 440 Hz for
resistive and reactive loads with
power factors as low as 0.2. Back-
to-back SCRs are configured for
zero voltage turn-on and can handle
current surges up to 8A. The
patented circuit design assures the
lowest possible EMI by virtually
eliminating commutation spikes
while maintaining excellent noise
immunity. Optical isolation allows
safe control of AC loads from low
level logic circuits. The low-profile
metal DIP package is hermetically

NOTES:
1. Case temperature is measured at point specified.
2. The dv/dt is 200 V/μs with recommended snubber across output
terminals R= 100 ohm, 1/2 W, C=0.01 μf (600V). The dv/dt rating is
based on a source impedance of 50 ohms.
3. Output may lose blocking capability during and after surge until TJ falls
below maximum.
4. Contact factory for additional specifications.
