Product details

The TLP183(BLL-TPL,E: Rated for 3750Vrms isolation between primary and secondary sides. Single DC-input channel with transistor output. The phototransistor saturates below 300mV Vce at 5mA LED drive, which keeps the logic-level low on a 3.3V or 5V MCU input without an extra pull-up resistor.

CTR binning and temperature range

Current transfer ratio is binned from 200% min to 600% max at If=5mA. The 'BLL' suffix selects the 200–600% range. The 6-SOP package has a 4.40mm body width, same footprint as a standard SOIC-6, so it drops onto existing layouts without a pad revision.

ROHS3 compliant, no exemption expiry to track. The 6-SOP package is widely second-sourced by other optocoupler manufacturers if a cross is ever needed, but the Toshiba TLP183 series is the primary reference for this footprint and CTR bin.

Frequently asked questions

What is the difference between TLP183(BLL-TPL,E and TLP183(BL-TPL,E?

The CTR bin. TLP183(BLL-TPL,E guarantees 200%–600% at 5mA, while the 'BL' bin is 100%–600%. The 'BLL' bin gives a tighter low-end floor, which matters if your LED drive current is fixed at 5mA and you need guaranteed saturation across temperature and aging.
