DESCRIPTION
• SMD lead available on tape and reel
The LH1546AD (4 pin DIP) is robust, ideal for telecom and
ground fault applications. It is an SPST normally open
switch (1 form A) that replaces electromechanical relays in
many applications. It is constructed using a GaAs LED for
actuation control and an integrated monolithic die for the
switch output. The die, fabricated in a high-voltage
dielectrically isolated BCDMOS technology, is comprised of
a photodiode array, switch control circuitry and MOSFET
switches. In addition, it employs current-limiting circuitry
which meets lightning surge testing as per ANSI/TIA-968-B
and other regulatory voltage surge requirements when
overvoltage protection is provided.
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
APPLICATIONS
• General telecom switching
- On/off hook control
- Ring relay
- Dial pulse
- Ground start
- Ground fault protection
• Instrumentation
• Industrial controls
Note
• See “solid-state relays” (application note 56)

Notes
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
(1) Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
