The ±6.25% tolerance on the nominal Zener voltage means the actual clamp point sits between 2.25 V and 2.55 V — tight enough for a low-voltage supply rail clamp or a simple shunt reference in an automotive ECU or sensor module. ## 1 W in SOD-128 — thermal reality for continuous use At 1 W max power, the junction temperature is rated to 150 °C. In a continuous shunt regulator, the power dissipated is Vz × Iz; at 2.4 V that means about 400 mA Zener current before hitting the 1 W ceiling. The SOD-128 package has a small footprint — the copper pad area under the cathode tab sets the effective thermal resistance, so a solid ground-plane connection is needed to keep junction temperature below the 150 °C limit in a hot under-hood environment. ## Active production — no obsolescence concern For volume production or a BOM line that needs an automotive-grade 2.4 V Zener, this part is a current-catalog choice — no supply-risk flag from the manufacturer.","metaTitle":"PDZVTFTR2.4B Zener Diode, 2.4 V, 1 W, AEC-Q101, SOD-128","metaDescription":"ROHM PDZVTFTR2.4B Zener diode, 2.4 V nominal, 1 W max power, ±6.25% tolerance, AEC-Q101 qualified, SOD-128 package.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Series":"Automotive, AEC-Q101","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±6.25%","Power - Max":"1 W","Mounting Type":"Surface Mount","Package / Case":"SOD-128","lifecycle_stage":"eol_hot","Impedance (Max) (Zzt)":"15 Ohms","Operating Temperature":"150°C (TJ)","Supplier Device Package":"PMDTM","Voltage - Zener (Nom) (Vz)":"2.4 V","Current - Reverse Leakage @ Vr":"200 µA @ 1 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.46","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.46000","currency":"USD"},{"qty":10,"price":"$0.37200","currency":"USD"},{"qty":100,"price":"$0.25340","currency":"USD"},{"qty":500,"price":"$0.19004","currency":"USD"},{"qty":1000,"price":"$0.14252","currency":"USD"},{"qty":3000,"price":"$0.13065","currency":"USD"},{"qty":6000,"price":"$0.12273","currency":"USD"},{"qty":15000,"price":"$0.11481","currency":"USD"},{"qty":30000,"price":"$0.11100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5aefc2f55ba31c7554c9e98627f10729.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is PDZVTFTR2.4B equivalent to other 2.4 V Zener diodes?","answer":"The PDZVTFTR2.4B is a 2.4 V Zener with 1 W power rating, ±6.25% tolerance, and AEC-Q101 automotive qualification in a SOD-128 package.
