The 1N821 from American Power Devices is a temperature-compensated Zener reference diode designed for stable voltage regulation.
This diode series offers a Zener voltage range of 5.9V to 6.5V, with specific models providing tighter tolerances. The 1N821 is rated for a maximum DC power dissipation of 500mW at +50°C, with power derating of 4 mW/°C above that temperature. It operates across a wide temperature range of -65°C to +175°C.
Key electrical characteristics include a Zener test current of 7.5mA and a maximum Zener impedance of up to 96 Ohms. The temperature coefficient varies by model, with some offering as low as 0.0005%/°C for high stability applications.
The 1N821 is housed in a hermetically sealed DO-35 package with through-hole mounting. The lead material is copper clad steel with a tin/lead finish. This series is available in JAN, JANTX, JANTXV, and JANS specifications for high-reliability applications.
