The package is well-suited for rework under hot air. The body marking is clear enough to identify pin 1 orientation (cathode band) after reflow. No special bake-out is required for standard MSL levels, but the part should be handled per ESD precautions given the junction is exposed to the soldering profile. The wide temperature margin also accounts for self-heating during repetitive clamping events. The device does not include power line protection features (no internal series element), so it is intended for parallel shunt clamping on signal or low-power DC rails, not for series fault interruption. ## Sourcing and lifecycle status For current pricing and lead time, submit an RFQ.","metaTitle":"Littelfuse 1.5SMB36CA TVS Diode, 1500W, DO-214AA","metaDescription":"Littelfuse 1.5SMB36CA bidirectional Zener TVS diode, 1500W peak pulse power, 30.8V standoff, DO-214AA SMB package.
