Product details
Overview
MUR260 from Taiwan Semiconductor is a 2 A, 600 V ultra-fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 50 ns reverse recovery time, 175°C maximum junction temperature, and glass passivated junction for high reliability in switching power supplies.
For engineers reviewing the MUR260 datasheet, MUR260 pinout, MUR260 application, or MUR260 equivalent, key selection criteria include forward voltage at 2 A (≤1.35 V), surge current rating (35 A), thermal resistance (RθJL = 17 °C/W), and AEC-Q101 qualification status of variant MUR260HA0G.
Technical Context
The MUR260 is a single-die, planar epitaxial ultra-fast recovery rectifier optimized for high-frequency switching applications. Its 50 ns trr and low junction capacitance (26 pF at 4 V) minimize switching losses and EMI generation during turn-off transitions.
Designed with glass passivation and pure tin-plated leads compliant with J-STD-002, the device supports reflow soldering and operates continuously from –55°C to +175°C. Thermal performance is characterized on a 10 mm × 10 mm copper pad PCB per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - blocks up to 600 V repetitive reverse voltage without breakdown |
| IF | 2 A - continuous average forward current rating at TL = 75°C |
| IFSM | 35 A - withstands 8.3 ms half-sine surge, critical for inrush and fault tolerance |
| trr | 50 ns - ultra-fast recovery minimizes reverse recovery charge and switching loss |
| TJ max | +175°C - enables operation in high-temperature environments like automotive under-hood DC/DC converters |
| RθJL | 17 °C/W - low junction-to-lead thermal resistance improves heat transfer to PCB copper |
| VF @ 2 A, 25°C | 1.09–1.35 V - forward voltage range directly impacts conduction loss and thermal design margin |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same 2 A / 600 V rating; trr = 55 ns (slightly slower); RθJL = 20 °C/W | Qualified to AEC-Q101 but not offered in ammo box packaging | Preferred where STMicroelectronics supply chain alignment is required; verify layout thermal relief for higher RθJL |
| ES2D | Lower IF = 2 A but only VRRM = 200 V; trr = 35 ns; smaller DO-214AA package | Not suitable for 600 V systems; used in low-voltage secondary-side SMPS | Only viable if system VRRM requirement is ≤200 V; not a drop-in replacement for MUR260 |
Compared with STTH2R06 and ES2D, the MUR260 offers superior thermal resistance (17 vs. 20 °C/W) and full 600 V capability-critical for high-bus industrial and automotive converters where voltage margin and thermal headroom directly impact field reliability.

FAQ
What is the maximum junction temperature rating for the MUR260?
The MUR260 has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table. This allows reliable operation in high-ambient environments such as automotive under-hood DC/DC modules or enclosed industrial power supplies. The MUR260 maintains specified electrical parameters up to this limit when thermal design accounts for RθJL = 17 °C/W and PCB copper area.
Is the MUR260 available in an AEC-Q101 qualified version?
Yes-the MUR260HA0G variant is explicitly qualified to AEC-Q101 for automotive applications. It shares identical electrical and thermal specifications with the base MUR260 but undergoes additional stress testing including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing. The "H" suffix denotes AEC-Q101 qualification in Taiwan Semiconductor's ordering code.
What is the reverse recovery time (trr) of the MUR260 and under what test conditions?
The MUR260 has a maximum reverse recovery time (trr) of 50 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the datasheet's Electrical Specifications table. This ultra-fast recovery enables efficient operation in 100–500 kHz switching converters where diode switching loss dominates total losses.
What package type does the MUR260 use and what are its mechanical highlights?
The MUR260 uses the DO-204AC (DO-15) axial package: molded plastic case rated UL 94V-0, pure tin-plated leads compliant with J-STD-002 solderability, and cathode polarity indicated by a visible band. Its weight is approximately 0.400 g, and it meets JESD 201 Class 2 whisker resistance requirements for long-term reliability in vibration-prone applications.
How does the forward voltage (VF) of the MUR260 vary with current and temperature?
At 25°C, VF is 1.09 V (typical) to 1.35 V (max) at IF = 2 A; at 150°C, it drops to 0.87–1.15 V due to negative temperature coefficient of silicon PN junctions. This reduction lowers conduction loss at elevated temperatures-critical for thermal stability in sealed enclosures where ambient rises during operation.
