BZX55C4V3 Zenerdiod 4.3V 500mW DO-35
Eq. 1N5229, 1N5229B, 1N5991, 1N5991B
Atari Lynx II (D13) BZX55C4V3 has a test current of 5mA and is a exact replacement for the original zener diode 1N5991B. If using 1N5229 that have a higher test current of 20mA and that can cause problem with low output voltage in the range of 4.4V and R74 has to be changed from 120ohms to 30ohms for proper zener operation.
Product Code: BZX55C4V3
