Current transfer ratio spans 160% minimum to 320% maximum at If=10 mA. Output transistor handles up to 70 V Vce and 50 mA continuous per channel. The 300 mV Vce(sat) at rated current keeps the voltage drop low enough that the output can drive a 5 V logic input or a small relay coil without an additional buffer transistor. ## Switching speed and package — line-feed considerations Rise and fall times are 3 µs and 4.7 µs typical; turn-on and turn-off times are 6 µs and 5 µs typical. This is a DC-coupled optocoupler for status feedback, fault signalling, and low-speed data — not for high-speed digital isolation above about 100 kbps. For a PLC digital input or a relay driver, the 3 µs edge is fast enough to avoid missing a pulse from a 1 kHz sensor. 4-SMD gull wing package with a 4-SOP supplier device package. The gull wing leads are pick-and-place friendly and self-align during reflow.","metaTitle":"Vishay TCLT1014 Optoisolator, 5000Vrms, 160-320% CTR, 4-SOP","metaDescription":"Vishay TCLT1014 transistor output optocoupler, 5000 Vrms isolation, 160-320% CTR, 4-SMD gull wing package.
