SMP-74 Photo-MOSFET Relay

Description

The SMP-74 Photo-MOSFET Relay series is a general purpose Form B solid-state relay featuring switching up to 400V AC or peak DC, in a very small SOP (small-outline package), SMD (surface mount design), or DIP (dual-in-line package). It also features a low output capacitance of 1.3pF and a low off-state leakage current of 1μA. Photo-MOSFET Relays also feature fast switching, no contact bounce, low noise, impervious to dirty environments, shock/vibration proof, extremely high input to output isolation, control low-level analog signals to high-level loads: (LED’s, relays, lamps, solenoids). The added benefit of stable on resistance, long life and high reliability make the SMP-74 Photo-MOSFET Relay series ideal in many applications.

Product Training Module – RF Reed Relays Part I

Welcome to Standex Electronics' RF Reed Relays Part I training module. Reed relays have long been known to have the capability to switch and carry RF signals and fast digital pulses. Hardly anyone thought reed relays were capable of switching and carrying RF up to 20 GHz, because the reed switch's leads are composed of nickel/iron which has a relatively high permeability or (MU). However, 20GHz is now a reality at Standex Electronics. We will be presenting the reasons Standex Electronics and their design team have made this possible.

Product Training Module – RF Reed Relays Part II

Welcome to Standex Electronics' RF Reed Relays Part II training module. This second RF presentation assumes you have already heard the first Standex Electronics RF Part I presentation. Understanding the simple physical layout of a reed relay makes it easy to design and rest reed relays for RF and fast digital pulse applications. RF is dependent on the physical layout or signal path it takes while going through circuits and the components that make up those circuits. We will show you how the physical layout of the reed relay will have a direct bearing on the RF signal's success going into and out of the reed relay. Coupled with the relay's physical layout, the materials making up the reed relay are also important.
