The Microchip 1N746A-1E3 is a 3.3 V Zener diode in the standard DO-35 axial-lead package, rated for 500 mW maximum power dissipation. The ±5% tolerance on the nominal voltage means the regulation point stays within 3.135 V to 3.465 V across the operating range — tight enough for most low-voltage rail clamping or reference applications.
