Product Summary

The SM8S33A is a surface mount automotive transient voltage suppressor.

Parametrics

SM8S33A maximum ratings: (1)Steady state power dissipation PD: 8.0 W; (2)Peak forward surge current, 8.3ms single half sine-wave IFSM: 700 A; (3)Typical thermal resistance junction to case RθJC: 0.90 ℃/W; (4)Operating junction and storage temperature range TJ, TSTG: -55 to +175 ℃.

Features

SM8S33A features: (1)Ideally suited for load dump protection; (2)Plastic package has Underwriters Laboratory Flammability Classification 94V-0; (3)High temperature stability due to unique oxide passivation and patented PARconstruction; (4)Integrally molded heatsink provides a very low thermal resistance for maximum heat dissipation; (5)Low leakage current at TJ = 175℃; (6)High temperature soldering guaranteed: 260℃ for 10 seconds at terminals; (7)Meets ISO7637-2 surge spec.; (8)Low forward voltage drop.
