The tape-and-box packaging (TB suffix) delivers the diodes in ammo-box format for axial insertion machines; the laser-etched marking on the body carries the full part number and date-code for lot traceability back to Taiwan Semiconductor's plant. ## Active production and sourcing posture No pin-compatible alternative within Taiwan Semiconductor's own catalog is listed as a direct successor.","metaTitle":"1.5KE33A A0G TVS Diode, 1500W, 28.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE33A A0G Zener TVS diode, 1500W peak pulse power, 28.2V reverse standoff, 45.7V clamping.
