The 1N821 from Siemens is a temperature-compensated Zener reference diode designed for applications requiring stable voltage regulation. It features a Zener voltage range of 5.9V to 6.5V at a test current of 7.5mA, with a maximum Zener impedance of 96Ω.
This diode boasts a low temperature coefficient of 0.01%/°C over an operating temperature range of -65°C to +175°C, ensuring reliable performance across various environmental conditions. The DC power dissipation is rated at 500mW at +50°C, with power derating of 4 mW/°C above that temperature.
Packaged in a hermetically sealed DO-35 case with through-hole mounting, the 1N821 has copper clad steel leads with a tin/lead finish. Its construction is metallurgically bonded with a double plug design, contributing to its reliability. The reverse leakage current is a maximum of 2μA at 3Vdc.
