The ±2% tolerance on the nominal Zener voltage means the regulation point stays tight across the operating range — useful for clamping a 15 V rail or as a reference in a shunt regulator where the load current stays under the 66 mA maximum. ## Parametric guardrails for the BOM Maximum impedance (Zzt) is 14 Ohms at the test current — this sets the dynamic regulation slope: a 10 mA load swing shifts the Zener voltage by roughly 140 mV. Reverse leakage is 5 µA max at 11.4 V, so the diode does not load the rail below the knee. Forward voltage drop is 1.2 V max at 200 mA if the diode is forward-biased. The full military temperature range of -65°C to 150°C covers most industrial and automotive under-hood applications without derating the power at the high end. ## Active production — sourcing through distribution The Tape & Reel packaging (TR suffix) suits automated pick-and-place, though the axial DO-41 body requires a formed-lead feeder or a through-hole insertion head.","metaTitle":"Microchip 1N4744CP/TR8 Zener Diode, 15V, 1W, ±2%, DO-41","metaDescription":"Active production 1N4744CP/TR8 Zener diode from Microchip. 15V nominal, 1W, ±2% tolerance, DO-41 axial.
