BROADCOM Solid State Relay (SSR), 60V, SO4 - 1A
BROADCOM SO4 solid-state relay for 60V loads. Features opto-isolation, 1A current rating, low on-resistance, and CMOS compatibility.
The BROADCOM ASSR series solid-state relay (SSR) offers a highly reliable, opto-isolated switching solution for demanding electronic applications. It consists of an AlGaAs infrared light-emitting diode (LED) input stage optically coupled to a high-voltage output detector circuit. This detector features a high-speed photovoltaic diode array and driver circuitry to switch on and off two discrete high-voltage MOSFETs.
A key advantage of this component is its compact, solid-state bi-directional signal switching capability. It provides low on-resistance and a high input-to-output insulation voltage, ensuring efficient operation and excellent electrical isolation for safety and signal integrity. The relay is designed with low input current, making it compatible with CMOS logic, and it offers very high output off-state impedance to minimise leakage currents.
This SSR is engineered for high-speed switching and features high transient immunity, making it robust against electrical noise and surges in harsh environments. Its surface-mount design and gull-wing terminals facilitate efficient PCB assembly and integration into modern electronic designs. The relay activates (contact closes) with a minimum input current of just 3mA through the input LED and deactivates (contact opens) with an input voltage of 0.8V or less.
With its single-pole, single-throw, normally-open (SPST-NO or 1 Form A) contact configuration, it is a versatile switch suitable for AC or DC loads. This solid-state design eliminates the mechanical wear, contact bouncing, and arcing associated with traditional electromechanical relays, resulting in a longer operational lifespan and silent, maintenance-free performance.
