Overview
1N6267A Series TVS Diodes 1500 Watt Zener Transient Voltage Suppressors Pb Maximum Ratings and Thermal Characteristics Rating Peak Power Dissipation (Note 1) @ TL ≤ 25°C Steady State Power Dissipation @ TL ≤ 75°C, Lead Length = 3/8 ≤ Derated above TL = 75°C Symbol Value PPK 1500 PD 5.
0 20 Unit W W mW/°C Thermal Resistance, Junction-to-Lead RθJL 20 °C/W Forward Surge Current (Note 2) @TA = 25°C Operating and Storage Temperature Range IFSM 200 A TJ, Tstg −65 to +175 °C/W Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously.
If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
