Overview
The ROHM Semiconductor 1SR154-400TE25 is a high-performance single rectifier diode designed for efficient power rectification in demanding electronic circuits. Its critical operational characteristic lies in its robust 1A forward current capability at a 400V reverse voltage, ensuring reliable operation in moderate power applications. A key design consideration for engineers selecting this component is the trade-off between its 1.1V forward voltage drop and the need for minimal power dissipation; while low, this Vf can impact efficiency in very high-frequency switching applications where cumulative losses become significant, necessitating careful thermal management and potential parallel configurations for higher current demands.
Key Features
- Reverse Voltage (Vr): 400 V
- Forward Current (If): 1 A
- Forward Voltage (Vf): 1.1 V
- Max Surge Current: 30 A
- Reverse Current (Ir): 10 µA
- Dimensions: 4.5 mm (L) x 2.6 mm (W) x 1.9 mm (H)
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.
- General-purpose rectification in AC-DC power supplies
- Reverse polarity protection for sensitive circuitry
- Output rectification in low-power SMPS (Switched-Mode Power Supplies)
- Signal demodulation in RF receiver front-ends
