The 15 V nominal breakdown sets the regulation point for shunt voltage-reference and clamping applications where a ±10% tolerance is acceptable. With a maximum impedance of 14 Ohms at the Zener test current (Zzt), the regulation slope is moderate — expect the output voltage to shift by roughly 14 mV per mA of load current change through the device. The 5 µA reverse leakage at 11.4 V confirms the knee is sharp enough for most general-purpose rail clamping and reference duties. ## Wide temperature range — military-grade envelope The forward voltage drop is specified at 1.2 V max when conducting 200 mA — useful for estimating conduction losses if the diode sees forward current during reverse-polarity events. The DO-41 axial package with through-hole mounting suits point-to-point wiring, breadboard prototyping, and PCB layouts where a leaded form factor simplifies manual replacement. The Tape & Reel packaging option supports automated assembly for volume production.","metaTitle":"Microchip 1N4744E3/TR13 Zener Diode, 15 V, 1 W, DO-41","metaDescription":"Microchip 1N4744E3/TR13 Zener diode, 15 V nominal, 1 W, ±10% tolerance, DO-204AL (DO-41) axial package.
