SMD marked as 312S (above the three is a dot)
function is simple switched 5V 500mA max from input pin 5 to output pin 2 , switchung drive MCU over diode marked as to P3_1 any as PNP transistor but have 6 pin case and any functionalit on pin 3
2. case marked as
1TI
R5R
size any as MSO8
it's a dual opamp on +5V any as LM358 but I would like to know the exact type
1. PVT312 ralay is in 6pin DIP and size equivalent SMD case, but my IC is in SMD case of size SOT23-6 . Relay on 250V in SOT23-6 is nonsense, because of insulation distances.
2. Yes I look on SMD code book 2014 and other known to me SMD code source but the result is big zero

312S wil be any High-Side Load Switch but what have input and output pin on center pin 2 and 5?
