The 1N5245B is a Zener diode designed for voltage regulation and reference applications. It provides a nominal Zener voltage of 15 V at a test current of 8.5 mA. Key characteristics include a maximum Zener impedance of 16 Ω and a low reverse leakage current of 0.1 μA at 11 V. The device has a power dissipation rating of 500 mW and operates over a wide junction temperature range from -65°C to +200°C. Housed in a hermetically sealed DO-35 glass package, the 1N5245B is suitable for general-purpose regulation, clipping, and protection circuits.
