Product details
Overview
MUR460_E from Diodes Incorporated is a super fast glass passivated rectifier diode rated for 600 V repetitive peak reverse voltage and 4.0 A average forward current at 120°C lead temperature, featuring 50 ns reverse recovery time, 1.28 V forward voltage at 4 A, and AEC-Q101 Rev_C qualification for automotive-grade reliability in power conversion stages.
For engineers reviewing the MUR460_E datasheet, MUR460_E pinout, MUR460_E application, or MUR460_E equivalent, this device is selected for high-efficiency AC/DC front-ends, boost PFC circuits, and flyback snubber networks where low trr, low VF, and robust thermal performance under transient surge are critical design requirements.
Technical Context
This device operates as a unidirectional power rectifier with a DO-201AD axial package, optimized for high-frequency switching (up to 20 kHz square-wave operation) using super-fast recovery characteristics. Its 50 ns trr and 40 pF junction capacitance support minimal switching loss in SMPS topologies.
The diode exhibits graded doping and optimized lifetime control to achieve stable reverse leakage (<10 µA at 25°C, <250 µA at 125°C) and thermal resistance of 11°C/W (junction-to-lead), enabling reliable operation up to 175°C junction temperature.
Key Specifications

| IF(AV) | 4.0 A @ TL = 120°C - Sustains continuous output current in thermally constrained PCB layouts |
| trr | 50 ns - Enables efficient operation in >100 kHz switch-mode supplies with low commutation loss |
| VF | 1.28 V @ IF = 4 A, TJ = 25°C - Reduces conduction loss in high-current DC bus paths |
| IR | 10 µA @ VR = 600 V, TJ = 25°C - Minimizes standby power loss in offline adapters |
| RthJL | 11 °C/W - Supports direct lead-mount thermal path for improved power dissipation |
| IFSMT | 110 A @ tp = 8.3 ms - Survives standard AC line surge events per IEC 61000-4-5 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH4R06DJF | Same DO-201AD package; 600 V VRRM, 4 A IF(AV), but trr = 35 ns (faster), VF = 1.45 V (higher) | Better suited for >200 kHz ZVS/ZCS topologies where recovery speed dominates loss budget | Select when minimizing reverse recovery charge outweighs forward conduction loss penalty |
| ON Semiconductor MUR460G | Identical ratings and DO-201AD package; same VF, trr, and thermal specs; differs only in marking and tape/reel packaging | No functional difference; fully interchangeable in all designs requiring AEC-Q101 compliance | Preferred for dual-sourcing programs requiring second-source validation without redesign |
Compared with STTH4R06DJF and MUR460G, the MUR460_E delivers optimal balance of low VF and moderate trr for cost-sensitive 65–150 kHz industrial and automotive power supplies, while maintaining full AEC-Q101 qualification and green material compliance.

FAQ
What is the maximum junction temperature rating for MUR460_E?
The MUR460_E has a specified maximum junction temperature (TJ) of +175°C, verified per AEC-Q101 Rev_C thermal cycling and high-temperature operating life testing. This allows uninterrupted operation in engine-bay-mounted LED drivers and industrial power supplies without thermal derating below 150°C ambient.
Is MUR460_E suitable for use in non-isolated buck-derived topologies?
Yes - its 50 ns trr, 1.28 V VF, and 110 A IFSM make it appropriate for synchronous rectifier replacement in high-side buck configurations where reverse recovery must be tightly controlled. However, it is not a Schottky diode and cannot replace ultra-low-VF devices in sub-1 V output applications.
Does MUR460_E require heatsinking in typical 4 A applications?
At 4 A average current and 120°C lead temperature, the DO-201AD package achieves thermal equilibrium with RthJL = 11°C/W. No external heatsink is required if PCB copper area ≥ 250 mm² per lead is provided; forced air or chassis mounting further extends safe operating area without additional thermal interface materials.
How does the AEC-Q101 qualification impact MUR460_E's use in industrial applications?
AEC-Q101 qualification subjects MUR460_E to accelerated stress tests including HTGB, HTRB, and temperature cycling far exceeding standard industrial requirements. This results in lower infant mortality, tighter parameter distributions, and proven reliability in harsh environments - making it preferred for industrial UPS, solar inverters, and motor drives despite no automotive end-use.
