12V 1/2W Zener Diode (5-Piece Pack)

Rounding out the 12V zener options already in the catalog, this 1/2-watt version is the lightest-duty of the three power ratings available at this voltage, intended for reference circuits and signal-level clamping that draw only a trickle of current through the diode. Keeping a spread of power ratings at the same common voltage lets a builder match the exact part to the actual current demand of their circuit rather than defaulting to an oversized part that costs more board space and money than the application needs.
