Procurement Notes
Verify the complete part number including suffixes such as BL, TPL, and E against official Toshiba Semiconductor and Storage documentation. Confirm that the specific ordering code matches the required packaging format and compliance standards before finalizing procurement orders to ensure component authenticity and specification alignment.
Selection Notes
Select this component when a single-channel transistor output isolator with 3750Vrms rating is required. Ensure the 50mA output current capability and 80V collector-emitter voltage meet the load requirements. Verify that the 6-SOP package dimensions fit the available PCB space and that the operating temperature range covers the intended environmental conditions.
Part Context
This device belongs to the TLP183 family of transistor output optocouplers manufactured by Toshiba Semiconductor and Storage. The series offers various configurations optimized for general-purpose isolation tasks. The specific model integrates standard phototransistor technology within a small outline package suitable for automated surface-mount assembly processes.
Replacement Considerations
Consult official Toshiba substitution guides for verified equivalents. Cross-referencing requires matching isolation voltage, output type, and package footprint. Generic replacements may not guarantee identical current transfer ratio or switching speed performance.
