The tape-and-reel packaging (R0G suffix) is the standard reel quantity for axial diodes — typically 1200 or 1400 pieces per reel depending on the manufacturer's reel diameter, which matters for pick-and-place if you are panel-mounting these on a carrier tape for automated insertion. ## Sourcing and compliance status No pin-compatible second-source is listed on the official record, but the 1.5KE series is a standard JEDEC-registered outline shared by multiple manufacturers — parametric equivalents exist if needed.","metaTitle":"1.5KE39A R0G TVS Diode, 1500W, 33.3V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE39A R0G Zener TVS, 1500W peak pulse, 33.3V reverse standoff, 53.9V clamp, DO-201 axial.
