Product details
Overview
MUR460H from Taiwan Semiconductor is an AEC-Q101 qualified ultra-fast recovery rectifier diode rated for 4 A average forward current and 600 V repetitive peak reverse voltage, with 50 ns reverse recovery time and 1.28 V max forward voltage at 4 A and 25°C, used in automotive-grade DC-DC converters and switching inverters.
For engineers reviewing the MUR460H datasheet, MUR460H pinout, MUR460H application, or MUR460H equivalent, key selection criteria include its DO-201AD package, 125 A surge rating, 175°C maximum junction temperature, glass-passivated junction, and AEC-Q101 qualification for under-hood power conversion systems.
Technical Context
The MUR460H employs a single-die silicon PN junction with glass passivation to ensure stable high-temperature operation up to 175°C and robust reliability under repetitive surge conditions. Its ultra-fast 50 ns trr enables high-frequency switching in SMPS topologies without excessive switching loss.
Designed for automotive power electronics, the device meets JESD201 Class 2 whisker resistance and RoHS/halogen-free requirements (IEC 61249-2-21), with pure tin-plated leads compliant to J-STD-002 solderability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH4R06DJF | Same DO-201AD package; 600 V VRRM; 45 ns trr; 1.25 V VF(max); no AEC-Q101 qualification | Targeted at industrial/commercial SMPS, not automotive-qualified systems | Select when AEC-Q101 is not required and faster recovery is prioritized over qualification documentation |
| ON Semiconductor MUR460E | DO-201AD; 600 V VRRM; 50 ns trr; 1.28 V VF(max); RoHS-compliant but not AEC-Q101 qualified | General-purpose replacement where automotive reliability validation is not mandated | Choose for cost-sensitive industrial designs needing identical electrical specs without automotive certification overhead |

FAQ
What is the maximum junction temperature rating for the MUR460H?
The MUR460H has a maximum junction temperature (TJ) rating of +175°C, enabling reliable operation in high-ambient environments such as automotive engine compartments and industrial power supplies. This rating is validated under AEC-Q101 stress testing and supported by its glass-passivated chip construction. The MUR460H maintains specified electrical parameters up to this limit, making it suitable for thermally constrained PCB layouts where active cooling is limited.
Is the MUR460H pin-compatible with non-AEC-Q101 versions like MUR460 or MUR460E?
Yes, the MUR460H shares identical DO-201AD package dimensions, lead configuration, and pinout with MUR460 and MUR460E - all feature axial leads with cathode band marking. However, the MUR460H adds AEC-Q101 qualification and enhanced process controls; electrical specs (600 V VRRM, 50 ns trr, 1.28 V VF) remain unchanged. The MUR460H can be substituted in existing designs where automotive qualification is later required.
What does the 'H' suffix signify in MUR460H?
The 'H' suffix in MUR460H explicitly denotes AEC-Q101 qualification per the Taiwan Semiconductor ordering code convention. It indicates full compliance with the AEC-Q101 stress test standard for discrete semiconductors, including HTSL, TC, UHAST, and bond wire pull tests. This distinguishes the MUR460H from standard MUR460 variants and confirms its suitability for automotive power electronics applications requiring certified reliability.
How does the MUR460H's reverse recovery time compare to standard fast recovery diodes?
The MUR460H achieves a typical reverse recovery time (trr) of 50 ns, significantly faster than standard fast recovery diodes (typically 100–500 ns). This enables higher switching frequencies and reduced switching losses in DC-DC converters. Measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions, the MUR460H's 50 ns trr is consistent across its operating temperature range and contributes directly to improved system efficiency in automotive and industrial SMPS designs.
Does the MUR460H meet halogen-free and RoHS requirements?
Yes, the MUR460H complies with both RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use pure tin plating. These specifications are verified in Taiwan Semiconductor's material declarations and support environmentally regulated markets including EU automotive and industrial equipment.
