Maximum Zener impedance is 14 Ohms at the test current. A lower impedance means the Zener voltage shifts less when the load current varies, which is the difference between a clean clamp and a sloppy one in a transient suppressor circuit. Forward voltage is 1.2 V maximum at 200 mA — the diode can also serve as a general-purpose rectifier in a pinch, though the 1 W power limit governs the forward current capability.","metaTitle":"Microchip 1N4744P/TR12 Zener Diode, 15 V, 1 W, DO-41","metaDescription":"Active 15 V Zener diode, 1 W, ±10% tolerance, DO-204AL (DO-41) axial package, Tape & Reel. -65°C to 150°C.
