The ±5% tolerance on the nominal Zener voltage means the regulation point sits between 10.45 V and 11.55 V across the operating range — tight enough for most low-power reference and clamping circuits. ## Parametric profile and operating limits Maximum impedance (Zzt) is 7 Ohms at the test current — this sets the dynamic resistance the load sees; a lower Zzt means tighter regulation under varying current draw. Reverse leakage is specified at 1 µA maximum at 8.5 V, well below the Zener knee, so the diode draws negligible current in the off state. Forward voltage is 1.4 V maximum at 1 A, typical for a silicon junction at this current density. The SQ-MELF B package (B, SQ-MELF) is a hermetic ceramic barrel with metallized end caps — it handles the temperature extremes and is suitable for high-reliability, avionics, or downhole applications where plastic packages would delaminate.","metaTitle":"1N6325US Zener Diode, 11 V, 500 mW, SQ-MELF B","metaDescription":"Microchip Technology 1N6325US Zener diode, 11 V nominal, ±5% tolerance, 500 mW, SQ-MELF B surface mount, -65°C to 175°C.
