RS1MFP

RS1MFP Description

The RS1MFP from onsemi is a high-voltage, fast-recovery rectifier diode designed for demanding automotive and general-purpose applications. With a 1000V reverse voltage (Vr) and 1.2A average rectified current (Io), this diode offers robust performance in high-voltage circuits. Its fast recovery time (300ns) and low forward voltage drop (1.3V @ 1.2A) ensure efficient switching and minimal power loss. Packaged in a SOD123HE surface-mount form factor, it is optimized for compact PCB designs while maintaining high reliability under harsh conditions.

RS1MFP Features

• High Voltage & Current Handling: Supports 1000V Vr and 1.2A Io, making it suitable for power supply and rectification tasks.
• Fast Recovery (≤500ns): Ensures reduced switching losses in high-frequency applications.
• Low Leakage Current: 5µA @ 1000V minimizes standby power consumption.
• Automotive-Grade Compliance: Meets stringent automotive reliability standards.
• Low Capacitance (18pF @ 0V): Enhances performance in high-speed switching circuits.
• RoHS3 & REACH Compliant: Environmentally friendly and suitable for global markets.
• Surface-Mount (SOD123HE): Ideal for space-constrained designs with MSL1 (Unlimited) moisture sensitivity.

RS1MFP Applications

• Automotive Systems: Used in ECUs, LED lighting, and DC-DC converters due to its high reliability.
• Power Supplies: Efficient rectification in AC-DC converters and SMPS.
• Industrial Electronics: Suitable for motor drives, inverters, and surge protection.
• Consumer Electronics: Ideal for fast-switching circuits in adapters and chargers.

Conclusion of RS1MFP

The RS1MFP stands out as a high-performance, automotive-grade diode with fast recovery, low leakage, and robust voltage handling. Its surface-mount design and compliance with environmental regulations make it a versatile choice for modern electronics. While marked as "Not For New Designs," it remains a reliable option for legacy systems requiring high-voltage rectification with minimal losses. Engineers can leverage its fast switching and low capacitance for efficient power management in automotive, industrial, and consumer applications.
