6.2 V zener in a SOT-223 outline
The Nexperia BZV90-C6V2,115 is a 6.2 V zener diode rated for 1.5 W continuous dissipation in a SOT-223 surface-mount package. The ±5% tolerance on the nominal voltage gives a regulation window tight enough for most low-voltage reference and clamp circuits.
Key ratings for the BOM
The 1.5 W power rating in a SOT-223 means the junction-to-ambient thermal path relies on the board copper — the SOT-223 tab is the main heat path, so a decent ground-plane pad is expected for continuous dissipation near the limit. The 10 Ω maximum impedance (Zzt) at the test current is typical for a 6.2 V zener; it keeps the regulation slope tight enough for most shunt applications. Reverse leakage is 3 µA at 4 V, which is low enough to not load a high-impedance bias divider.
The SOT-223 package is common enough that date-code consistency and marking verification are straightforward — the laser etch on the package face should match Nexperia's plant font for the week code; any mismatch flags a suspect part.
