CHICAGO, January 13, 2021 - Littelfuse, Inc. (NASDAQ: LFUS), a global manufacturer of leading technologies in circuit protection, power control and sensing, today announced the CPC1561B Solid State Relay (SSR). The CPC1561B is the highest current (1 A, 60 V) normally open SSR currently available on the market to integrate both current-limiting and thermal shutdown circuits. The small, surface-mount CPC1561B SSR’s dual fault protection benefit provides a rugged solution for demanding applications that is not possible when using electro-mechanical relays and standard SSRs. Typical markets and applications for the CPC1561B include:
• Smart homes
• Building Automation
• Gaming

There are 100’s of different kind of optocouplers, so that’s why I don’t here go closer to the specs, same goes for the Mosfet. The principal idea is that when the switch, (or logic), is LOW, the optocoupler LED is ON. R1 is the LED current limitor resistance, (you need to dimension it to your own demands). Thank you Trishpota, The diode rating will be twice of the load current rating. If load is 2 amp, then diodes must be 4 amps. Only 12V to 17 V DC will be enough for the MOSFET switching. Yes the opto will need to be switched externally from an external trigger source, because in an SSR the input and output is supposed to be completely isolated. The opto-isolator (IC1) and its two resistors R1 and R2 are not absolutely essential to the operation of the MOSFET but are highly desirable because the complete circuit makes a very useful self contained switch, suitable for interfacing many low voltage, low current electronics projects to higher voltage/current peripherals.
Opto Isolator Relay Driver
The combination of photovoltaic coupler and MOSFET can be used to realize contactless relay. Parametric Search Triac Output Photocouplers / Thyristor Output Photocouplers Triac-output photocouplers are suitable for controlling AC loads. Thyristor-output photocouplers are used to control AC loads that are directly connected to a 100-Vac or 200. IX4351NE 9A Low-Side SiC MOSFET & IGBT Gate Driver; P/N Index, Application Notes, & PCNs.

'The CPC1561B is ideal for markets and applications that cannot be down for long periods of time due to over current, over temperature and electrical stress,' said Steve Andrezyk, Director of Marketing for Littelfuse-IXYS Integrated Circuits. 'The CPC1561B output relay can survive harsh conditions and resume normal operation once the fault is removed, thus reducing product down-time and potentially eliminating service call time as the SSR both protects itself and resets to resume normal operation.'
