The 0.4 W dissipation ceiling sets the maximum steady-state current the diode can handle: at a nominal Zener voltage around 11 V, continuous current is limited to roughly 36 mA before the junction temperature climbs out of the part's safe operating area. For a field-swap scenario, that means this diode is fine on a logic-level bias rail or a low-current sensor supply, but it is not the part for a power bus clamp where the fault current could push past 50 mA. ## No official second source on file No pin-compatible cross-reference or direct replacement is listed in the manufacturer's documentation. If you are dual-sourcing for supply resilience, you will need to qualify a functionally equivalent Zener from another vendor against your specific voltage and power requirements — the 0.4 W rating and the Zener voltage tolerance are the parameters to match.","metaTitle":"HZS11A3TD-E Zener Diode, 0.4 W, Active","metaDescription":"HZS11A3TD-E Zener diode, 0.4 W power dissipation.
