Notes
1. Continuous output current capability so long as T_J is ≤ T_J(MAX).
2. ESD1 testing is performed in accordance with the Human Body Model (C_ZAP=100 pF, R_ZAP=1500 Ω), ESD3 testing is performed in
accordance with the Charge Device Model (CDM).
3. The limiting factor is junction temperature, taking into account power dissipation, thermal resistance, and heatsinking.
4. 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.
5. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL),
Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e.
MC33xxxD enter 33xxx), and review parametrics.
6. Maximum power dissipation at indicated ambient temperature.
