The CPC1973Y is a single-pole, normally open, solid state relay with optically coupled MOSFET outputs for high-reliability switching in industrial, medical, and instrumentation applications. It is housed in a 4-pin Power SIP package with dimensions of 10.160 mm x 5.080 mm, and provides 2500 V rms input-to-output isolation. It handles continuous load currents up to 0.35 A rms with a maximum on-resistance of 5 Ω and a blocking voltage of 400 V. The device operates over an ambient temperature range of -40 °C to +85 °C, meets UL 508 and CSA component safety standards, and is certified to EN IEC 62368-1. It has a typical turn-on time of 5 ms and turn-off time of 3 ms at 25 °C, with low drive power requirements and no EMI/RFI generation.
Optically isolated solid state power relays (MOSFET-based). Power SIP Packages: Pin-to-pin compatibility with other solid state relays, easy upgrade path for existing designs, compatibility for new designs.Input to Output Isolation up to 4000VRMS For power applications requiring a non-biased heat sink with superior thermal management properties, the i4-PAC and ISOPLUS-264 power relays are an ideal solution. For high-current applications requiring enhanced isolation, the new Power SOIC is an ideal choice. To upgrade existing designs or to design compatible new designs, select the Power SIP, which offers pin-for-pin compatibility with many existing power relays. Current Loads up to 15 Arms @ Tc=25°C Dc Loads up to 32 A at 25°C Voltage ratings up to 1 kV Low On-resistance Compact i4-PAC Package Industry Standard 4-Pin SIP Package Low input control current Up to 5 kVrms input-to-output isolation Low thermal impedances: 0.35°C/W - i4-PAC
