The ±10% tolerance on the nominal voltage means the actual Zener voltage for any given unit falls between 6.75 V and 8.25 V — a spread that matters when the diode sets a reference rail or clamps a supply line that feeds a 5 V regulator. ## Parametric fit for a clamp or reference Reverse leakage is specified at 10 µA maximum with 5 V reverse bias; at the Zener voltage the leakage is higher, but the 1 W power rating gives headroom for continuous operation at currents up to roughly 133 mA (1 W / 7.5 V), derated for ambient temperature above 25 °C. Forward voltage is 1.2 V maximum at 200 mA forward current — this is the standard silicon diode drop and confirms the part behaves as a conventional rectifier in the forward quadrant when used in a back-to-back clamp pair. The through-hole DO-41 body with axial leads is a standard footprint for hand-assembly or wave-solder lines; the tape-and-reel packaging (TR suffix) suits automated insertion equipment.","metaTitle":"Microchip 1N4737P/TR12 Zener, 7.5 V, 1 W, DO-41","metaDescription":"Active Microchip 1N4737P/TR12 Zener diode, 7.5 V ±10%, 1 W, DO-204AL (DO-41) axial.
