About Solid State Relays (SSR)

Solid-state relays electronically switch signals without mechanical contacts, using semiconductors like MOSFETs or TRIACs. Unlike electromechanical relays, SSRs operate silently, have no contact bounce, and offer faster switching speeds with virtually unlimited cycle life.

SSRs provide crucial isolation between control circuits and load voltages, preventing ground loops and voltage spikes. They’re essential in noise-sensitive applications, extreme environments (-40°C+), and systems requiring high cycling frequency like automated test equipment or process control.

Packaging Options

Available in industry-standard Tape & Reel (TR) for automated assembly, with Cut Tape (CT) options for prototyping needs. PCX maintains ready stock in both configurations.

Frequently Asked Questions

Q: What’s the difference between SPST-NO and other relay formats?
A: SPST-NO (Single Pole Single Throw – Normally Open) has one switch circuit that closes when activated, unlike SPDT relays which can route to multiple paths.

Q: Can this relay switch AC and DC loads?
A: Yes, the CPC1017NTR supports both AC and DC loads within its 0-60V/100mA rating.

Q: Is an external snubber circuit required?
A: For resistive loads under 100mA, no snubber is typically needed. For inductive loads, consult Littelfuse’s datasheet for design recommendations.

Q: What’s the typical lifespan of this SSR?
A: OptoMOS® relays typically exceed 1 billion operations due to solid-state construction – 100x longer than mechanical relays.

Q: Can I parallel multiple relays for higher current?
A: Not recommended due to potential current imbalance. Select a higher-current SSR model instead.

Q: Does PCX provide technical support for integration?
A: Yes! Our engineering team offers design-in assistance and datasheet analysis – contact [email protected].
