Product Description
Broadcom ASSR-4118-503E is a high-performance Solid State Relay designed for switching AC loads with a maximum load current of 0.1 A and load voltage up to 400 V. This surface mount device (SO-4 package) integrates a high-efficiency AlGaAs infrared LED input coupled optically to a MOSFET output, delivering superior electrical isolation and long operational life.
The relay supports low control voltages from 1.1 V to 1.6 V, making it compatible with low-power control circuits such as CMOS. With a low on-resistance of 8 ohms for DC and 25 ohms typical for AC/DC switching, it minimizes power dissipation during operation.
Engineered to operate reliably within a temperature range of -40°C to +85°C, the device is suitable for challenging industrial and commercial environments. Its compact dimensions (4.4 mm x 2 mm) facilitate easy integration into densely populated PCBs, and PCB terminal types ensure secure mounting and quick installation.
The 1μA off-state leakage current and 0.4 pF capacitance contribute to minimal signal distortion and energy efficiency, suitable for precision switching tasks. The SPST contact design and compliance with RoHS standards underline the solid quality and environmental compliance of this product.
Applications include telecommunications switching, data communications, industrial automation, medical equipment, and security systems, providing reliable, maintenance-free switching solutions.
The relay provides a compact, bi-directional solid-state signal switch. Its low input current design is compatible with CMOS inputs for easy control. High input-to-output insulation voltage enhances safety and noise immunity.
The device acts as an EMR and Reed Relay replacement for enhanced durability. RoHS compliant and adheres to industry environmental standards.
Broadcom’s ASSR series solid state relays combine compact size, efficient power handling, and compatibility for a wide range of electronic switching applications. Browse similar Solid State Relays and broadcom products on EnvMart for advanced automation and control gear solutions.
