TLP531(HIT-BL-T1,F is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Toshiba Semiconductor and Storage. Its product description is PHOTOCOUPLER. Review the specifications below when checking this part for your BOM.
The TLP531(HIT-BL-T1,F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a gallium arsenide infrared emitting diode with a phototransistor in a six-lead plastic DIP package. Key electrical specifications include a minimum collector-emitter voltage of 55 V, a minimum current transfer ratio of 50%, and a minimum isolation voltage of 2500 Vrms. The device is UL recognized under file number E67349.
Verify the specific suffix (HIT-BL-T1,F) against official Toshiba documentation to confirm lead-free status and tape-and-reel packaging details. Ensure the component meets RoHS directives if required by your manufacturing process. Cross-reference the UL file number E67349 for regulatory compliance requirements in your target market.
Select this component when designing circuits requiring galvanic isolation between control and load sides. The transistor output type is suitable for switching low-voltage DC signals. Consider the 55 V collector-emitter rating and current transfer ratio characteristics to ensure proper interface with downstream logic or relay drivers.
This part belongs to the TLP531 series of transistor output optocouplers from Toshiba. The series is designed for general-purpose isolation tasks. Variants within the series may differ in base connection configurations or specific electrical ranking parameters, but share the fundamental optoelectronic structure and DIP-6 packaging format.
