Maximum power dissipation is 1 W, so the steady-state zener current at 15 V is limited to about 66 mA before the junction temperature rise needs derating — the DO-204AL (DO-41) axial lead body relies on the PCB copper and airflow to shed that heat. Maximum zener impedance (Zzt) is 14 Ohms at the test current — a lower impedance means tighter voltage regulation under varying bias, which matters when the diode is used as a shunt reference or a low-power clamp. Supplied in Tape & Reel (TR) packaging, the through-hole DO-204AL (DO-41) axial body suits automated insertion or hand assembly — the reel format is standard for volume pick-and-place with axial feeders.","metaTitle":"1N4744APE3/TR8 Zener Diode, 15 V, 1 W, DO-41, Active","metaDescription":"Microchip Technology 1N4744APE3/TR8 zener diode, 15 V nominal, ±5% tolerance, 1 W power, DO-204AL (DO-41) axial package.
