Product details

6 V nominal, 500 mW — DO-35 axial regulator

The HZ6A2L90TA is a 6 V zener diode in the HZ series, rated for 500 mW continuous power dissipation in a DO-204AH (DO-35) axial-lead package. The ±2.5% tolerance on the nominal voltage gives tighter regulation than the standard ±5% grade, which matters when the zener is used as a shunt reference or a low-voltage clamp.

175°C junction — high-ambient headroom

Rated junction temperature goes to 175°C, so the part can sit in a hot enclosure — engine bay, industrial cabinet, near a heatsink — without derating the power budget prematurely. The 40 Ohm maximum zener impedance at the test current means regulation stiffens once the diode is biased above the knee; at low bias currents the output voltage will sit a bit higher than the nominal 6 V.

Active production — no LTB watch needed

No official second source or pin-compatible cross is documented for this exact HZ series variant, so the BOM line is single-sourced from the manufacturer.

Frequently asked questions

What is the power rating of HZ6A2L90TA?

Maximum continuous power dissipation is 500 mW.

Can I replace HZ6A2L90TA with a 6V zener?

Any 6 V zener in a DO-35 package with a 500 mW power rating and ±2.5% or looser tolerance is a functional replacement, but no official cross-reference is recorded for this specific HZ series variant. Confirm the reverse leakage and impedance match the circuit requirements before substituting.
