This Neo-Iso SSR is an alternative to mechanical relays and opto-MOS. It
offers up to 10 times lower control current and RDSon, protection from
overcurrent including a feedback status pin, a 90% smaller package, and
higher robustness because there is no moving part. The on/off commands
are sent with a simple transient‐immune differential clock signal from
any microcontroller. The device also includes integrated 240 mΩ
bidirectional load switch allowing AC or polarity free applications up
to 36V peak.

"Semtech's new Neo-Iso solid state relay expands our platform with an
enhanced feature set required for Internet of Things (IoT) such as
automated building systems market," said Francois Ricodeau, Sr. Product
Line Manager for Semtech's Wireless and Sensing Products Group. "Our new
SSR is powered and controlled from a simple clock interface, thus
reducing the design-in effort to a minimum for engineers. We believe
Semtech's Neo-Iso platform will become the standard for multiple

The new Neo-Iso SSR, TS13501, supports DC and AC systems and is priced
at $0.62 in volumes of 10,000 units. For more information, visit the

About Semtech's Neo-Iso™ Solid State Relays

Semtech's Neo-Iso technology is an energy harvesting platform engineered
for self-powered control systems. It enhances Internet of Things
applications, such as smart home technology, by adding higher levels of
intelligence and control. Our compact Neo-Iso switches make it possible
for low-power microcontrollers to control high voltage loads in a
system. Reporting of fault conditions from the switch to the controller
enables system responses resulting in a safer, more efficient operation.
Low current draw allows each switch to operate on power harvested from
the load, eliminating the need for additional supplies. These isolated
power switches are designed as a silent operation with low quiescent
operating current and a single control panel for on/off input.
