MUR1510

MUR1510 Description

The MUR1510 from onsemi is a high-performance 100V, 15A general-purpose rectifier diode from the SWITCHMODE™ series, designed for fast recovery and efficient power conversion. Encased in a TO-220-2 through-hole package, this diode is optimized for high-current, high-voltage applications requiring rapid switching and low power loss. With a reverse recovery time (trr) of just 35 ns and a forward voltage drop of 1.05V at 15A, it minimizes energy dissipation, making it ideal for demanding power electronics. Although marked as obsolete, its robust design and compliance with REACH Unaffected and EAR99 regulations ensure reliability in legacy systems.

MUR1510 Features

• Ultra-Fast Recovery: Trr of 35 ns ensures minimal switching losses, outperforming standard rectifiers.
• High Current Capacity: 15A average rectified current (Io) with a low 10 µA reverse leakage at 100V.
• Low Forward Voltage: 1.05V max @ 15A reduces thermal stress and improves efficiency.
• Durable Packaging: TO-220-2 through-hole mount for easy integration and heat dissipation.
• Industry-Standard Compliance: REACH Unaffected, MSL 1 (Unlimited) moisture resistance, and EAR99 export classification.

MUR1510 Applications

The MUR1510 excels in:

• Switch-mode power supplies (SMPS): Fast recovery minimizes noise and improves efficiency.
• DC-DC converters: Low Vf and trr enhance performance in high-frequency circuits.
• Freewheeling diodes: Protects inductive loads in motor drives and inverters.
• Rectification in industrial equipment: Reliable operation in high-current, high-voltage environments like welding machines and UPS systems.

Conclusion of MUR1510

The MUR1510 is a proven solution for high-efficiency, fast-switching applications, offering a balance of speed, current handling, and thermal performance. While obsolete, its SWITCHMODE™ pedigree ensures compatibility with legacy designs requiring dependable rectification. Engineers seeking a low-loss, high-reliability diode for power electronics will find it a cost-effective choice, particularly in industrial and automotive systems where durability and efficiency are critical.
