The 1N4749ATR is a 24V Zener diode manufactured by On Semiconductor, designed for voltage regulation and reference applications. It offers a nominal zener voltage of 24V with a ±5% tolerance, ensuring precise voltage clamping. With a power dissipation rating of 1W, it can handle moderate power levels in through-hole designs.
This device features a maximum zener impedance of 25Ω at the test current, providing stable voltage regulation. The reverse leakage current is specified at 5µA maximum at 18.2V, ensuring low power loss in standby conditions. The diode is housed in a DO-204AL (DO-41) axial-leaded package, suitable for through-hole mounting on PCBs.
Operating over a wide temperature range of -65°C to 200°C, the 1N4749ATR is suitable for harsh environments. It is RoHS3 compliant and REACH unaffected, though these compliance claims are unverified. The part is commonly used in power supplies, voltage clamping, and reference circuits.
