That isolation rating covers reinforced insulation requirements for industrial power supplies, motor drives, and PLC I/O modules where the primary and secondary sides need a solid safety barrier. ## CTR range and switching speed The current transfer ratio spans 200% to 400% at a 5 mA forward current. Typical rise and fall times are 2 µs and 3 µs, with turn-on and turn-off both at 3 µs. ## Package and mounting Supplied in a tube, the part is a surface-mount 6-SOIC with a 0.173-inch body width and 4.40 mm height — the 4-lead variant leaves two pins unpopulated. The 80 V output rating and 50 mA continuous output current cover most signal-level isolation needs.","metaTitle":"TLP385(BLL,E Optoisolator – 5000Vrms, DC Input","metaDescription":"Toshiba TLP385(BLL,E optoisolator: 5000Vrms isolation, DC input, transistor output, 6-SOIC package, 200-400% CTR at 5 mA.
