1N5998B Description

Short technical summary and product information.

The 1N5998B is a Zener Diode from On Semiconductor, specified with a nominal Zener voltage of 8.2V and a tolerance of ±5%. It is designed for voltage regulation and protection circuits requiring a stable reference voltage. The device offers a maximum power dissipation of 500mW at a lead temperature of 75°C, with a derating factor of 4.0 mW/°C above 75°C.

 

Electrical characteristics include a test current of 5 mA, a dynamic resistance of 7 Ω, and a knee impedance of 600 Ω at 250 µA. The maximum Zener current is 61 mA, and reverse leakage current is 0.5 µA at 6 V. The forward voltage is 1.2 V at 200 mA. The operating temperature range spans from -65°C to 200°C.

 

The diode is housed in a DO-35 glass axial-lead package, designed for through-hole mounting. The cathode is identified by a color band. This part is part of the 1N5985B-1N6025B series and is suitable for general-purpose Zener diode applications.
