Notes
1.
ESD testing is performed in accordance with the Human Body Model (HBM) (AEC-Q100-2), and the Machine Model (MM) (AEC-Q100-
003), RZAP = 0Ω
2.
Per JEDEC51 Standard for Multilayer PCB
3.
Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
4.
45V is the Maximum allowable voltage on all LED channels in off-state.
