Technical Details & Description

5000Vrms isolation in a 4-DIP through-hole package

The Renesas NEPOC PS2561B-1-L-A is a single-channel DC-input transistor-output optocoupler in a 4-DIP (0.300", 7.62mm) through-hole package.

200% to 400% CTR at 5 mA — design margin for aging and temperature

The current transfer ratio (CTR) is specified at 200% minimum and 400% maximum when the LED is driven with 5 mA forward current. The 300mV maximum Vce saturation at 50 mA output current keeps power dissipation low.

The NEPOC series is a mature, widely-used optocoupler family with consistent supply. ROHS3 compliance is confirmed, so the part meets current environmental regulations for European and global markets.

Frequently asked questions

What is the price of PS2561B-1-L-A?
