H11B1-X009T is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Vishay Semiconductor Opto Division. Its product description is OPTOISO 5.3KV DARL W/BASE 6-SMD. Review the specifications below when checking this part for your BOM.
The H11B1-X009T is a single-channel optocoupler manufactured by Vishay Semiconductor Opto Division. It features a DC input and a Darlington transistor output with base access, housed in a 6-pin SMD package. The device provides an isolation voltage of 5300Vrms. Key electrical parameters include a maximum collector-emitter voltage of 18V, a peak forward current of 25mA, and a minimum current transfer ratio of 500% at 1.6mA input. Typical switching times are 600ns for turn-on and 1.5µs for turn-off. The component operates within a temperature range of -55°C to 100°C.
Verify the specific suffix X009T against official Vishay documentation to confirm packaging and tape specifications. Confirm availability status as distribution data may indicate end-of-life or limited stock conditions. Ensure the selected variant matches the required lead time and reel quantity constraints for production integration.
Select this component when high current transfer ratio is required for driving loads directly. The integrated base allows for faster switching or linear operation compared to standard phototransistors. Verify that the 18V output voltage rating meets the circuit requirements. Consider thermal dissipation limits given the SMD package constraints.
This part belongs to the H11B series of Vishay optocouplers. It is distinct from the H11B2 model which also uses a Darlington output but may differ in specific electrical characteristics or pinout configurations. The X009T suffix denotes the specific surface-mount packaging format provided by the manufacturer.
Public confirmed substitutes include the H11B2-X009T. Verify compatibility regarding pinout and electrical ratings before substitution.
