Product details

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.
