This part is a single 20 V zener diode in an axial DO-41 package with a 5% nominal zener-voltage tolerance. Standard 1N4747A family data shows 1.0 W power dissipation at a lead temperature of 50°C with derating above that point. Typical family characteristics include a 22 mA test current, 12.5 Ω maximum zener impedance at test current, and 5 µA maximum reverse leakage at 15.2 V. The axial package corresponds to JEDEC DO-204AL, and standard family operating and storage temperature range is -65°C to +200°C.
