Notes:
2. Exceeding these ratings may damage the device.
3. Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when
handling and transporting these device.
4. Test condition for DFN4030-14: Measured on approximately 1” square of 1 oz copper.
5. The device function is not guaranteed outside of the recommended operating conditions.
