DESCRIPTION
The LH1503 relays are DPST normally open switches
(2 form A) that can replace electromechanical relays in many
applications. The relays are constructed using a GaAlAs
LED for actuation control and an integrated monolithic die
for the switch output. The die, fabricated in a high voltage
dielectrically isolated technology, is comprised of a
photodiode array, switch control circuity, and DMOS
switches. In addition, these relays employ current limiting
circuity, enabling them to pass lightning surge testing as
per ANSI/TIA-968-B and other regulatory voltage surge
requirements when overvoltage protection is provided.
FEATURES
• Current limit protection
• Isolation test voltage 5300 V_RMS
• Typical R_ON 20 
• Load voltage 350 V
• Load current 110 mA
• High surge capability
• Clean bounce free switching
• Low power consumption
• High reliability monolithic receptor
• SMD lead available on tape and reel
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
APPLICATIONS
• General telecom switching
- On/off hook control
- Ring delay
- Dial pulse
- Ground start
- Ground fault protection
• Instrumentation
• Industrial controls
