Description

The 1N4733A is a 5.1V, 1W Zener diode designed for voltage regulation and protection in electronic circuits. It operates in the reverse breakdown (Zener) region, maintaining a stable voltage across its terminals when the current exceeds the minimum knee current.
### Key Features:
- Zener Voltage (Vz): 5.1V (typical at 49mA)
- Power Dissipation (Pz): 1W
- Tolerance: ±5%
- Max. Reverse Leakage Current: 5µA (below breakdown)
- Package: DO-41 (axial lead)
### Applications:
- Voltage regulation in power supplies
- Overvoltage protection
- Reference voltage source
### Notes:
- Requires a current-limiting resistor in series.
- Operates effectively within 20mA–178mA (1W limit).
A cost-effective, reliable choice for low-power regulation.
