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.","metaTitle":"HZ6A2L90TA Zener Diode, 6V, 500mW, DO-35, ±2.5%","metaDescription":"HZ6A2L90TA 6V zener diode, 500mW power dissipation, DO-35 axial package, ±2.5% tolerance, 175°C junction rating.","metaKeywords":null},"attributes":{"series":"HZ","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":[],"specifications":{"Series":"HZ","Package":"Bulk","Tolerance":"±2.5%","Power - Max":"500 mW","Mounting Type":"Through Hole","Package / Case":"DO-204AH, DO-35, Axial","lifecycle_stage":"eol_hot","Impedance (Max) (Zzt)":"40 Ohms","Operating Temperature":"175°C (TJ)","Supplier Device Package":"DO-35","Voltage - Zener (Nom) (Vz)":"6 V","Current - Reverse Leakage @ Vr":"5 µA @ 2 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.17","stockQuantity":0,"priceTiers":[{"qty":1758,"price":"$0.17000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/894888660f7e6e8bc627041d173e0812.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the power rating of HZ6A2L90TA?","answer":"Maximum continuous power dissipation is 500 mW."},{"question":"Can I replace HZ6A2L90TA with a 6V zener?","answer":"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.
