SP746-X Zero Cross 600V / 1.2A AC Solid State Relay Description Features The SP746-X is a bi-directional, single-pole, single-throw, normally open multipurpose solid-state relay. The circuit is composed of one input IR LED with a series limiting resistor 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 SP746-X provides high peak load voltage (600V+) and high input-to-output isolation voltage (up to 5kVRMS). The SP746-X comes in a compact 4 pin SIP package, making it ideal for high-density board applications.

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: 1 5 Relay Input Signal is Turned On Relay Input Signal is Turned Off Input Signal 2 SCR #1 Turns On when 5V threshold is reached 6 SCR #1 and Relay Turn Off at Zero Volts 5V Threshold (Zero Cross Voltage) Load Signal 3 4 SCR #1 Turns Off, SCR #2 Turns On at Zero Volts SCR #2 Turns Off, SCR #1 Turns On at Zero Volts 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. © 2015 Solid State Optronics • San José, CA www.ssousa.com • +1.408.293.4600 Page 3 of 6 SP746-X /H/S/TR Rev 2.10 (02/27/2015) 002414 SP746-X Zero Cross 600V / 1.2A AC Solid State Relay SP746-X Solder Reflow Temperature Profile Recommendations (1) Infrared Reflow: Refer to the following figure as an example of an optimal temperature profile for single occurrence infrared reflow.
