The 1N990B is a Zener voltage regulator diode from Microchip Technology, part of the 1N957B-1N992B series of 0.5 watt Zener diodes. It provides a nominal Zener voltage of 160V with a tolerance of ±5%, making it suitable for voltage regulation and reference applications.
This diode features a power dissipation of 500mW and a forward voltage of 1.1V at 200mA. The reverse leakage current is 5µA at 121.6V, and the Zener impedance (Zzt) is 1700Ω. It operates over a wide temperature range from -65°C to 175°C.
The 1N990B is housed in a DO-7 (DO-204AA) glass axial-leaded package, designed for through-hole mounting. The cathode is indicated by a band on the body. This package offers robust mechanical and thermal performance for general-purpose voltage regulation.
The nominal Zener voltage is 160V.
The power dissipation is 500mW.
The tolerance is ±5%.
The forward voltage is 1.1V at 200mA.
The operating temperature range is -65°C to 175°C.
The 1N990B is available in a DO-7 (DO-204AA) through-hole package.
