It delivers a nominal zener voltage of 12 V with ±3% tolerance, rated for 500 mW continuous power dissipation in the DO-219AC (microSMF) surface-mount package. ## What the 500 mW rating means for your board At 12 V nominal, 500 mW translates to roughly 42 mA continuous zener current before hitting the thermal ceiling at 25°C ambient. In a 105°C under-hood environment, the allowable dissipation drops to about 60% of the 500 mW rating, so budget the clamp current accordingly.","metaTitle":"PLZ12B-HG3_A/H Zener Diode, 12 V, 500 mW, AEC-Q101, DO-219AC","metaDescription":"Automotive-grade 12 V zener diode in DO-219AC microSMF package. 500 mW power dissipation, ±3% tolerance, 150°C junction rating.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101, PLZ","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Series":"Automotive, AEC-Q101, PLZ","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±3%","Power - Max":"500 mW","Mounting Type":"Surface Mount","Package / Case":"DO-219AC","lifecycle_stage":"eol_hot","Impedance (Max) (Zzt)":"12 Ohms","Operating Temperature":"150°C","Supplier Device Package":"DO-219AC (microSMF)","Voltage - Zener (Nom) (Vz)":"12 V","Current - Reverse Leakage @ Vr":"200 nA @ 9 V","Voltage - Forward (Vf) (Max) @ If":"900 mV @ 10 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.37","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.37000","currency":"USD"},{"qty":10,"price":"$0.30100","currency":"USD"},{"qty":100,"price":"$0.15950","currency":"USD"},{"qty":500,"price":"$0.10494","currency":"USD"},{"qty":1000,"price":"$0.07136","currency":"USD"},{"qty":2000,"price":"$0.06437","currency":"USD"},{"qty":4500,"price":"$0.06436","currency":"USD"},{"qty":9000,"price":"$0.05597","currency":"USD"},{"qty":13500,"price":"$0.04757","currency":"USD"},{"qty":31500,"price":"$0.04477","currency":"USD"},{"qty":112500,"price":"$0.04356","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/21f24ba8dccd996b40ae563db262d071.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to PLZ12B-HG3_A/H?","answer":"No official cross-reference or second-source alternate is listed in the available records.
