High Industrial Performance (HIPpak) Solid-State Relays
Mounting
HIPpak SSRs must be mounted on heat
sinks. A large range of heat sinks is
available. For heat-sink mounting, use
thermal grease or a thermal pad with high
conductibility specied by Teledyne.

Typical Loads
STH relays are designed for AC-51 resistive loads (heating). For other loads, consult our selection guide.
Protection
To protect the SSR against a short-circuit of the load, use a fuse with a I2t value = 1/2 I2t value specied.
EMC
Immunity:
Our data sheets list the immunity level of our SSRs according to the main standards for these of products: IEC/EN61000-4-4 and
IEC/EN61000-4-5. You can compare the high immunity level with other products on the market.
Emission:
Teledyne SSRs are designed in compliance with standards for class A equipment (Industry).
Use of this product in domestic environments may cause radio interference. In this case the user may be required to employ
additional devices to reduce noise. SSRs are complex devices that must be interconnected with other equipment (loads, cables,
etc.) to form a system. Because the other equipment or interconnections may not be under Teledyne’s control, it shall be the
responsibility of the system integrator to ensure that systems containing SSRs comply with the requirement of any rules and
regulations applicable at the system level.
