0.25 W Zener — what the power rating means for the BOM
The HZ3BLLTA-E is a 0.25 W Zener diode for low-power voltage reference or clamping. The 0.25 W ceiling sets the maximum steady-state current at the Zener voltage.
Sourcing posture — quoted to order per BOM line
Sourced through independent distribution, the HZ3BLLTA-E is quoted to order against the specific BOM quantity. The active lifecycle means the factory line is running, so lead times track the normal semiconductor cycle rather than a shrinking surplus pool.
