EN60747 Isolation Characteristics
Types: TLP781, TLP781F
Type designations for ‘option: (D4) ’, which are tested under EN60747 requirements.
Ex.: TLP781 (D4-GR-LF6) D4: EN60747 option
GR: CTR rank name
LF6: standard lead bend name
Note: Use TOSHIBA standard type number for safety standard application.
Ex. TLP781 (D4-GR-LF6) → TLP781
