These are 13V Zener diodes with similar voltage and power ratings. Verify specs (power dissipation, tolerance) for exact replacement.
Features
- Voltage: 5.8V (nominal Zener voltage)
- Power Dissipation: 1.5W
- Tolerance: ±5%
- Forward Voltage: 1.2V (max)
- Operating Temperature: -65°C to +150°C
- Package: SMA (DO-214AC)
- Low Leakage Current: <1µA (at working voltage)
Ideal for surge protection, voltage clamping, and regulation in circuits. Compact and reliable for consumer electronics, automotive, and industrial applications.
Application
- Consumer Electronics: Protecting USB ports, HDMI, and other interfaces.
- Automotive Systems: Safeguarding ECUs, sensors, and infotainment systems from voltage spikes.
- Industrial Equipment: Shielding control circuits and communication lines (RS-485, CAN bus).
- Telecom & Networking: Defending against ESD and surges in routers, switches, and base stations.
- Power Supplies: Clamping overvoltage in DC-DC converters and AC/DC adapters.
Its bidirectional design and high surge capability make it ideal for ESD and surge protection in sensitive electronics.
