Overview
The MURD620CT is a silicon rectifier diode manufactured by onsemi, designed for high-speed switching applications. It features a dual common cathode configuration housed in a TO-252 (DPAK) surface-mount package with three pins. The device supports a maximum repetitive peak reverse voltage of 200 V and an average forward current of 6 A per leg. Key electrical characteristics include a fast reverse recovery time of 35 ns and a low forward voltage drop of 1.2 V at rated conditions. It withstands a non-repetitive peak forward surge current of 50 A and operates within a junction temperature range from -65°C to 175°C.
Feature Summary
- Ultrafast reverse recovery performance with 35 ns typical recovery time
- Soft recovery characteristic to minimize electromagnetic interference during switching
- High thermal stability with glass-passivated junction and extended operating temperature range up to 175°C
- Robust surge handling capability suitable for demanding power conversion environments
Applications
- Negative switching power supplies
- Inverter circuits
- Freewheeling diode implementations
- Single-phase full-wave bridge rectification when paired with complementary devices
Procurement Notes
Verify the specific suffix against official documentation, as ordering codes may indicate variations in packaging or automotive qualification status. Confirm RoHS compliance and lead-free status requirements for your assembly process. Ensure the TO-252 footprint matches your PCB design constraints. Cross-reference the manufacturer's latest datasheet revision to validate all electrical parameters before finalizing component selection.
Selection Notes
Select this component for designs requiring rapid switching speeds and low conduction losses in compact form factors. The dual common cathode topology simplifies circuit layout compared to discrete single-diode solutions. Evaluate thermal management needs based on the 6 A rating and ensure adequate heatsinking or copper area for the DPAK package. Consider the soft recovery feature if minimizing voltage spikes is critical for system reliability.
Part Context
This device belongs to the SWITCHMODE Power Rectifier family from onsemi, engineered for efficient power conversion. It serves as a complement to the MURB1620CT common cathode device in certain bridge configurations. The product line emphasizes high efficiency and stress protection through guard-ring technology, catering to modern power supply and instrumentation demands.
Replacement Considerations
The RURD620CCS9A is a confirmed substitute part number available from multiple manufacturers including Fairchild and Renesas. This alternative maintains similar 6 A and 200 V specifications in a compatible TO-252AA package.
