Overview
The ON-SEMI 1N5404 is a robust diffused junction rectifier designed for general-purpose high-current rectification. Its primary function is to convert AC to pulsating DC with a critical characteristic being its substantial 3A forward current rating. A key design consideration often overlooked is managing thermal dissipation; while the 1N5404 boasts a low forward voltage drop (typically 0.95V at 3A), exceeding its peak repetitive reverse voltage (PRV) of 400V or inadequate heatsinking can lead to premature junction failure due to thermal runaway, a common trade-off in cost-effective, high-current discrete rectifiers.
Key Features
- Forward Current: 3A
- Peak Repetitive Reverse Voltage (PRV): 400V
- Forward Voltage Drop: 0.95V (Max) at 3A
- Reverse Leakage Current: 5µA (Max) at 400V
- Operating Temperature Range: -55°C to 150°C
- Package: DO-201AD (Molded Plastic)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Power supply rectification in industrial control systems
- AC to DC conversion in consumer electronics power bricks
- Reverse polarity protection in automotive circuits
- Freewheeling diode for inductive load switching
