Product details
Overview
MURS360 from Diodes Incorporated is a 3.0A, 600V surface-mount super-fast rectifier diode with 50ns reverse recovery time, 1.25V forward voltage at 3A, and 3μA leakage current at 600V. It serves as a boost diode in discontinuous/critical-mode PFC circuits and as a freewheeling diode in switch-mode power supplies.
For engineers reviewing the MURS360 datasheet, MURS360 pinout, MURS360 application, or MURS360 equivalent, key selection criteria include its 600V VRRM, 50ns tRR, SMC (Type C) package thermal performance (RθJC = 10°C/W), and AEC-Q101 readiness for automotive-grade power conversion designs.
Technical Context
The MURS360 employs glass-passivated silicon die construction to achieve stable super-fast switching with minimal charge storage. Its 50ns reverse recovery time and low 40pF junction capacitance enable high-frequency operation in PFC stages and DC-DC converters without excessive switching loss or EMI generation.
Rated for 3.0A average forward current at TC = +140°C and capable of withstanding 100A non-repetitive surge current (8.3ms half-sine), it supports robust operation under transient overloads common in industrial and automotive power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - blocks up to 600V reverse voltage in boost and flyback topologies without breakdown |
| IO | 3.0 A - continuous rectified output current at case temperature ≤ +140°C |
| tRR | 50 ns - enables efficient operation at ≥100 kHz switching frequencies in PFC and SMPS |
| VF | 1.25 V @ 3A - limits conduction loss to ~3.75W at full load, reducing thermal stress |
| IR | 3 μA @ 600V, 25°C - ensures minimal leakage in high-impedance hold-up or sensing paths |
| RθJC | 10 °C/W - allows direct heat transfer to PCB copper or heatsink, supporting compact thermal design |
| IFSM | 100 A peak - withstands inrush and fault currents without bond-wire failure |
Pinout & Package
Package: SMC (Type C) - molded plastic case, UL 94V-0 rated, 0.249g weight, matte tin-plated terminals, cathode identified by band or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/switch node in boost/flyback; requires low-inductance layout to minimize ringing |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail or energy storage node; cathode band marks polarity for automated placement |
Key Features

Applications
| AC-DC Power Factor Correction | Automotive DC-DC Converters |
|---|---|
Use Scenario: Boost diode in critical-conduction-mode (CrCM) PFC stage of 300–500W server PSU. IC Role / Device Role / Timing Role: Unidirectional energy transfer during MOSFET off-time; fast turn-off minimizes reverse recovery loss. Use Value: 50ns tRR reduces switching loss by >35% vs. standard fast rectifiers, improving efficiency to >96%. | Use Scenario: Freewheeling diode in 12V→5V/3.3V buck converter for ADAS camera module. IC Role / Device Role / Timing Role: Provides low-loss current path during high-side switch off-time; handles 100A surge during cold-crank events. Use Value: 100A IFSM and -55°C to +175°C operating range ensure reliable operation across automotive temperature extremes. |
| Industrial Motor Drive Snubbers | Telecom Rectifier Modules |
Use Scenario: Clamp diode in IGBT snubber network for 3-phase 7.5kW VFD output stage. IC Role / Device Role / Timing Role: Absorbs inductive kickback energy during IGBT turn-off; fast recovery prevents voltage overshoot. Use Value: 600V VRRM and 10°C/W RθJC allow direct mounting to heatsink, enabling compact snubber design. | Use Scenario: Output rectifier in 48V telecom brick supplying 12V/20A to base station control board. IC Role / Device Role / Timing Role: High-efficiency secondary-side rectification; low VF reduces conduction loss at full load. Use Value: 1.25V VF at 3A yields only 3.75W dissipation, easing thermal management in dense 1U chassis. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | Same 600V/3A rating; tRR = 45ns, VF = 1.30V @ 3A; TO-277 package (lower RθJC = 8°C/W) | Better thermal performance but larger footprint; not SMC-compatible | Select when board space permits and junction-to-case thermal resistance is critical |
| ES3J | 600V/3A; tRR = 35ns, VF = 1.70V @ 3A; same SMC package | Lower tRR but higher conduction loss; less suitable for high-current, low-VF priority designs | Select when ultra-fast recovery dominates over forward loss in <10A peak-current applications |
Compared with STTH3L06S and ES3J, the MURS360 delivers optimal balance of low VF (1.25V), industry-standard SMC footprint, and AEC-Q101-aligned qualification-making it preferred for cost-sensitive, thermally constrained, and automotive-qualified PFC and SMPS designs.

FAQ
What is the maximum junction temperature for continuous operation?
The MURS360 has an operating junction temperature range of –55°C to +175°C. Continuous operation at TJ = +175°C requires strict thermal design: case temperature must be held ≤ +140°C per the IO derating curve, with RθJC = 10°C/W and adequate PCB copper area or heatsinking.
Is MURS360 qualified for automotive applications?
The MURS360 is built in IATF 16949-certified facilities and meets AEC-Q101 stress test requirements for discrete diodes. While not pre-qualified as a standard automotive part, Diodes offers PPAP-capable change control and automotive-specific testing upon request for qualified customers.
How does the SMC (Type C) package compare to SMA or SMB in thermal performance?
The SMC (Type C) package provides lower thermal resistance than SMA (RθJC ≈ 15°C/W) and SMB (RθJC ≈ 12°C/W), with RθJC = 10°C/W. Its larger copper pad area (D = 7.75–8.13 mm) and dual-side thermal path enable superior heat dissipation in high-power density layouts.
Can MURS360 replace standard FR306 or UF306 diodes?
Yes-MURS360 replaces FR306 (600V/3A, tRR ≈ 500ns) and UF306 (600V/3A, tRR ≈ 75ns) in SMC footprint. Its 50ns tRR cuts switching loss significantly, but layout must accommodate identical SMC pad dimensions and cathode marking orientation.
