Visão Geral
Description
- Zener Voltage (Vz): 5.6V (nominal) at a test current of 53mA.
- Power Dissipation: 1W (requires heat sinking near max ratings).
- Tolerance: ±5% for precise regulation.
- Package: DO-41 axial leaded.
### Applications:
- Voltage regulation in power supplies.
- Overvoltage protection.
- Voltage reference in circuits.
### Notes:
- Operates in reverse bias (breakdown region).
- Current must be limited via a series resistor.
A cost-effective, reliable component for low-power regulation.
Equivalent
- BZX55C5V6 (5.6V, 500mW)
- 1N4734 (Same specs, lower tolerance)
- 1N5234B (5.6V, 500mW)
- MM3Z5V6 (5.6V, 200mW SMD)
- BZT52C5V6 (5.6V, 200mW SMD)
Check voltage, power rating, and package compatibility before substitution.
Features
- Voltage: 5.6V (nominal Zener voltage at 45mA test current).
- Power Dissipation: 1W (derate above 50°C).
- Tolerance: ±5% (for tighter regulation).
