This SPST-NO solid state relay uses an LED-based optoisolator for signal actuation, giving a high voltage dielectrically isolated component that can switch up to 350V AC or DC. The relay employs current limiting circuitry that meets lightning surge testing to ANSI/TIA-968-B and other regulatory voltage surge requirements. Suitable applications include telecomms, instrumentation, high-voltage test equipment, TRIAC-driver, motor-control circuits, industrial control systems, etc. * Supplied in a DIL-6 package * Current limit protection * High surge capability * Clean, bounce-free switching * Low power consumption * Isolation voltage 5300V * UL, CSA, BSI, FIMKO, DIN EN approvals To find out more about our range of Vishay resistors, diodes, capacitors and switches, please visit our Vishay brand page. https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2025-01-19 https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2025-05-14 https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2025-06-20 https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2025-07-29 https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2025-08-18 https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2025-09-29 https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2026-06-05 https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2026-06-28 https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2026-07-22 https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2026-08-14 https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2026-10-01 https://elecena.pl/product/27714488/vishay-lh1540at-spst-no-solid-state-relay-1-45v-120ma 2026-10-24
