Taiwan Semiconductor ABSOLUTE MAXIMUM RATINGS (TA = 25°C unless otherwise noted) PARAMETER SYMBOL LIMIT UNIT Input Supply Voltage (Note 2) VIN -18 ~ +60 V Input Supply Voltage VOPR 26 V Power Dissipation (Note 3) PD Internally Limited W Operating Junction Temperature Range TJ -40 ~ +125 °C Storage Temperature Range TSTG -65 ~ +150 °C THERMAL PERFORMANCE PARAMETER PACKAGE TYPE SYMBOL LIMIT UNIT TO-220 60 Thermal Resistance TO-263 80 RӨJA °C/W Junction to Ambient TO-252 150 SOT-223 170
Notes:
RӨJA is the sum of the junction-to-case and case-to-ambient thermal resistances. The case thermal reference is defined at the solder mounting surface of the drain pins. RӨJA is guaranteed by design while RӨCA is determined by the user’s board design. RӨJA shown below for single device operation on FR-4 PCB in still air.
