1N5349 Zener DIODE 1N-5349

The 1N5349 is a high-power silicon Zener voltage regulator diode typically housed in a rugged, axial-leaded molded plastic package like the DO-201AD or T-18. It is engineered to provide precise voltage regulation with a nominal Zener voltage of 12V and a tight standard voltage tolerance of plus or minus 5%. Designed to handle substantial energy loads, it boasts a hefty maximum power dissipation of 5.0 watts and can withstand high surge stresses up to 180W. Featuring a very low reverse leakage current of just 2 microamperes and low dynamic impedance, this reliable component is highly utilized in stabilized power supplies, surge protection frameworks, and industrial voltage-clamping circuits across a wide temperature window of -65°C to 200°C.
