800V / 1.2A
AC Solid State Relay
Description
The SP946 is a bi-directional, single-pole, single-throw,
normally open multipurpose solid-state relay. The circuit is
composed of one input IR LED which activates an optically
coupled IC on the output that controls the firing angle of
two back-to-back SCRs. This circuit assures no false
triggering under most adverse conditions, and a tight zero-
volt switching window not exceeding 5V. The SP946
provides high peak load voltage (800V+) and high input-to-
output isolation voltage (up to 5kVRMS).
The SP946 comes in a compact 4 pin SIP package, making
it ideal for high-density board applications.

ZERO-VOLT SWITCHING
This solid state relay has been designed with a driver circuit that controls the operation of two back-to-back silicon controlled rectifiers
(SCRs), each responsible for one half of the AC cycle. If an AC signal is examined, the turn on, turn off and zero-volt switching can be
seen. Figure 3 shows a typical 60 HZ, 120VAC signal with a corresponding relay input signal:

Figure 3: Zero-Volt Switching Cycle
Figure 3 shows the sequence of zero-volt switching operation. At Stage 1, an input signal is applied to the relay. The relay will not turn
on until the threshold voltage of 5V is reached. Once this point is reached (Stage 2), SCR #1 (designated as the SCR which controls
positive AC voltage) turns on. However, SCR #1 only conducts for an instant, as the cycle quickly crosses zero. At this point (Stage 3),
SCR #1 will turn off and SCR #2 (negative AC voltage) turns on. Likewise, at the next zero cross (Stage 4), SCR #2 will turn off and
SCR #1 conducts again. Even though the input signal is terminated at Stage 5, the relay will continue to conduct (typical SCR
behavior) until Stage 6, when SCR #1 crosses zero and ceases to conduct. Please note that turn on can likewise begin on the negative
phase of the AC cycle with a -5V threshold, though only the positive phase is shown here.
