An SSR is a relay with no moving contacts, and employs semiconductor switching elements like triacs, thyristors, and diodes. Solid state relays are designed for applications that require high switching speed and feature low switching acoustical noise and extremely long life. These relays are used when direct control by electronic circuits is necessary and switching without arcing or contact chatter is required. SSRs are not a replacement but complement electromechanical power relays.
TE Connectivity SSR Relays: AC and DC Solid State Relays
Features
- AC SSRs are qualified to MIL-PRF-28750/9 for 2A rated JDS9 series, and /10 for 25A rated JPS10 series, and to DSCC drawing 86031 for the 10 A PS12 series.
- DC SSRs are qualified to loads from low level to 2 Amps/60V.
- Some TE DC SSR relays are available with optional status monitoring and/or short circuit protection.
- 10 and 25A rated AC SST mounting configurations are designed primarily for panel or chassis mounting.
- The 2A rated AC JDS9 series and all DC models are designed for printed circuit board mounting, with some models configured for surface mount connection.
- Most models are approved to the applicable military specification, MIL-PRF 28770, or associated detail drawings.
- Special application specific models can be made available.
