The ±1% tolerance on the nominal voltage means this part holds the regulation point tighter than the standard 5% Zener — useful when the downstream circuit cannot tolerate a 0.6 V shift in the clamp threshold. ## Impedance and leakage — what governs the real regulation Maximum Zener impedance (Zzt) is 7 Ohms at the test current. Combined with the 1 µA maximum reverse leakage at 9 V reverse voltage, the diode draws negligible current below the breakdown knee — it stays out of the circuit until the rail hits the clamp voltage. The forward voltage spec of 1.4 V max at 1 A forward current confirms the diode can also serve as a general-purpose rectifier in low-current paths, though the 500 mW power limit restricts continuous forward duty.","metaTitle":"Microchip 1N6326DUS Zener Diode, 12 V, ±1%, 500 mW, SQ-MELF","metaDescription":"Microchip Technology 1N6326DUS Zener diode, 12 V nominal, ±1% tolerance, 500 mW, SQ-MELF B package, -65 to 175°C.
