DESCRIPTION
The PS9531, PS9531L1, PS9531L2 and PS9531L3 are optically coupled isolators containing a GaAlAs LED on the
input side and a photo diode, a signal processing circuit and a power output transistor on the output side on one chip.
The PS9531 Series is designed specifically for high common mode transient immunity (CMR), high output current
and high switching speed.
The PS9531 Series is suitable for driving IGBTs and MOS FETs.
The PS9531 Series is in a plastic DIP (Dual In-line Package).
The PS9531L1 is lead bending type for long creepage distance.
The PS9531L2 is lead bending type for long creepage distance (Gull-wing) for surface mount.
The PS9531L3 is lead bending type (Gull-wing) for surface mounting.
FEATURES
Long creepage distance (8 mm MIN.: PS9531L1, PS9531L2)
Large peak output current (2.5 A MAX., 2.0 A MIN.)
