FAQ
What is the ESD capability of the DZ23C22-HE3_A-08?
The device provides an ESD capability of greater than 8 kV according to the human body model and greater than 800 V according to the machine model, as per AEC-Q101 standards.
How does the power dissipation rating change based on mounting?
The total power dissipation is rated at 500 mW when the thermal resistance to lead is 250 K/W. When mounted on an FR-4 board with the recommended soldering footprint, the power dissipation is limited to 300 mW.
What is the significance of the HE3_A suffix?
The HE3_A suffix indicates that the device is RoHS-compliant and qualified to the AEC-Q101 automotive standard, distinguishing it from the base E3 commercial grade variants.
