The -65°C to 175°C operating range spans military and avionics temperature profiles, so the regulation point holds across the thermal extremes of an engine bay, satellite orbit, or downhole tool. ## Parametric guardbands for the BOM Maximum Zener impedance (Zzt) is 1.5 kOhms at the test current — this sets the dynamic resistance the load sees; a lower impedance means tighter regulation as the bias current varies. Reverse leakage is specified at 5 µA max at 3.5 V reverse voltage, which is the leakage budget for the node the diode protects. Forward voltage is 1.4 V max at 1 A — useful if the diode is also used as a clamping element in the forward direction. ## Active lifecycle — sourcing posture No pin-compatible replacement is needed for this line item.","metaTitle":"1N6316US Zener Diode, 4.7 V, 500 mW, SQ-MELF","metaDescription":"Microchip Technology 1N6316US Zener diode, 4.7 V nominal, 500 mW, SQ-MELF B package, -65 to 175 °C.
