6N135-L 6N136-L series
Part No. : 6N135-L 6N136-L series
BNS-OD-FC002/A4
1. DESCRIPTION
The 6N135/ 6N136-L consists of a high efficient AlGaAs Light Emitting Diode and a high speed optical detector. This design
provides excellent AC and DC isolation between the input and output sides of the Optocoupler. Connection for the bias of the photodiode
improves the speed that of a conventional phototransistor coupler by reducing the base-collector capacitances. The internal shield
ensures high common mode transient immunity. A guaranteed common mode transient immunity is up to 1KV/μsec.
1.1 Features
High speed – 1MBd typical
Available in Dual-in-line, Wide lead spacing, Surface mounting package.
Storable output.
UL, CSA approval
1.2 Applications
Isolation in line receivers
Digital isolation for A/D, D/A conversion
Ground loop elimination
Feedback Element in Switching Mode Power Supplier
Pulse transformer replacement
Power transistor isolation in motor drives
Interface between Microprocessor system, computer and their peripheral
