The 1N821-1 is a temperature compensated Zener reference diode designed for applications requiring stable voltage references. It is part of the 1N821 thru 1N829A series, offering nominal voltages such as 6.2V and 6.55V.
Key electrical characteristics include a Zener test current of 7.5mA, with a maximum Zener impedance of 15 Ohms for certain part numbers. The temperature coefficient is as low as 0.0005% / °C for specific variants, ensuring stable operation across a wide temperature range of -65°C to +175°C.
This diode is housed in a hermetically sealed glass case with a DO-35 outline and axial lead termination. The mounting type is through-hole, making it suitable for various PCB assembly processes. The maximum DC power dissipation is 500mW at +50°C, with power derating of 4mW/°C above this temperature.
