The ±2% tolerance on the nominal voltage means the breakdown sits between 14.7 V and 15.3 V at the specified test current — tight enough for a reference rail in a linear regulator or as a shunt clamp in a 15 V bus. Maximum impedance (Zzt) is 14 Ohms at the Zener test current, which keeps the voltage regulation tight under varying bias. Reverse leakage is specified at 5 µA max with 11.4 V across the junction — a useful sanity check when the diode is used as a low-power voltage reference rather than a brute-force clamp. ## Temperature Range and Package Operating junction temperature spans -65 to 150 °C, so this part handles the full industrial temperature envelope and then some. The DO-41 axial package is through-hole, easily hand-soldered or wave-soldered, and the tape-and-reel format (TR suffix) suits automated insertion for volume builds. Forward voltage drop is 1.2 V max at 200 mA forward current — not a primary spec for Zener operation, but relevant if the diode sees brief forward conduction in a clamp application. ## Active Lifecycle and Sourcing Microchip lists this part as active in its current product portfolio.","metaTitle":"Microchip 1N4744CE3/TR13 Zener Diode, 15 V, 1 W, DO-41","metaDescription":"1N4744CE3/TR13 Zener diode from Microchip, 15 V nominal, ±2% tolerance, 1 W power dissipation, DO-41 axial package.
