| LH1502BB/BAC/BACTR Dual 1 Form A/B, C Solid State Relay FEATURES * Current Limit Protection * l/O Isolation, 3750 VRMS * Typical RON 20 * Load Voltage 350 V * Load Current 150 mA * High Surge Capability * Linear, AC/DC Operation * Clean Bounce Free Switching * Low Power Consumption * SMD Lead Available on Tape and Reel AGENCY APPROVALS * UL - File No. E52744 * CSA - Certification 093751 * BSI APPLICATIONS * General Telecom Switching - On/off Hook Control - Ring Delay - Dial Pulse - Ground Start - Ground Fault Protection * Instrumentation * Industrial Controls DESCRIPTION The LH1502 relays contain normally open and normally closed switches that can be used independently as a 1 Form A and 1 Form B relay, or when used together, as a 1 Form C relay. The relays are constructed as a mult.chip hybrid device. Actuation contral is via an Infrared LED. The output switch is a combination of a photodiode array with MOSFET switches and control circuity.
