FEATURES/BENEFITS
• Industry standard package
• Designed for external heat-sink attachment
• Over-sized thyristor ratings
• Direct-copper bonding technology
DESCRIPTION
These solid-state single inline package (SIP)
relays are designed for mounting on printed circuit
boards. The Series LS relays facilitate heat sinking
by providing an interface surface. The relays are
designed with 16A, 25A and 50A thyristors. They can
switch loads with high starting currents. The nominal
switched currents depend on the size of the heat sink
and are limited by the cross section of the tracks of
the printed circuit (mainly 25A/30A). The relays use a
direct-bonded copper substrate for thermal efficiency,
thermal stress performance and long-life expectancy.

In each case, allow 0.16 in. (4mm) between the printed circuit board and the heat sink to keep a correct insulation
between input to output (0.16 in./4mm insulated washer). To maintain a good contact between the SSR and the heat
sink, use thermal grease.
