16 V zener, 500 mW, DO-35 axial
The 1N6005C is a 16 V zener diode from Microchip Technology, rated for 500 mW continuous power dissipation in a DO-35 axial-lead glass package. The ±2% tolerance on the zener voltage means this part is suited for reference or clamping circuits where a standard ±5% zener would exceed the regulation window.
Parametric fit for precision bias and clamping
Maximum zener impedance (Zzt) is 36 Ohms at the test current — this dynamic resistance determines how much the zener voltage shifts with current variation; lower Zzt means tighter regulation. Reverse leakage is specified at 100 nA maximum with 12 V applied across the junction — 4 V below the zener knee, so the diode draws negligible current in the off state. Forward voltage is 1.1 V maximum at 200 mA, consistent with a standard silicon signal diode — the part can also serve as a general-purpose rectifier in low-current auxiliary paths.
