The 1N6002B/TR is a 12 V Zener diode in a DO-35 axial package, rated for 500 mW continuous power dissipation. The ±5% tolerance is the standard bin for general-purpose voltage reference and clamping — the regulation point lands between 11.4 V and 12.6 V at the specified test current.
Temperature range and reverse leakage
Operating from -65°C to 175°C, the junction handles the full military temperature band — useful in avionics or downhole equipment where the ambient exceeds 125°C. Reverse leakage is specified at 100 nA maximum at 9.1 V reverse bias, which is the knee region below the 12 V breakdown. Forward voltage is 1.1 V maximum at 200 mA forward current — the diode conducts as a standard rectifier when forward-biased, though the primary application is reverse-breakdown regulation.
