Product details
Overview
NUR460/L02,112 from NXP Semiconductors is an ultrafast epitaxial power diode in axial-leaded SOD141 (DO-201AD) package, designed for high-frequency switching in PFC and SMPS stages. It delivers 600 V repetitive peak reverse voltage, 4 A average forward current, 1.28 V forward voltage at 4 A/25 °C, 25–65 ns reverse recovery time, and low thermal resistance (55 K/W junction-to-ambient).
For engineers reviewing the NUR460/L02,112 datasheet, NUR460/L02,112 pinout, NUR460/L02,112 application, or NUR460/L02,112 equivalent, key selection criteria include soft recovery behavior, low VF at high junction temperature, DCM-compatible dynamic performance, and axial-leaded mechanical compatibility with legacy through-hole power supply layouts.
Technical Context
This diode employs epitaxial construction to achieve fast, soft reverse recovery-critical for reducing EMI and snubber losses in discontinuous-mode PFC and high-frequency flyback converters. Its ramp-recovery trr of 33–65 ns and step-recovery trr of 25–50 ns are measured under standardized dIF/dt = 50 A/µs conditions, ensuring predictable turn-off behavior across operating temperatures.
Thermal design is supported by a junction-to-ambient Rth(j-a) of 55 K/W in free air, enabling reliable operation up to 150 °C junction temperature. The device sustains non-repetitive surge currents up to 110 A (8.3 ms sine), making it suitable for transient overload handling in industrial AC-DC front-ends.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast power diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6006D | 600 V VRRM, 6 A IF(AV), TO-220AC package, trr = 35 ns (typ) | Higher current rating but larger footprint; requires heatsinking above 3 A continuous | Select when higher average current (>4.5 A) or surface-mount compatibility is required |
| ON Semiconductor MUR460 | 600 V VRRM, 4 A IF(AV), DO-201AD package, trr = 60 ns (max), VF = 1.3 V | Nearly identical mechanical and electrical specs; slightly higher VF and longer max trr | Preferred for cost-sensitive designs where 0.02 V VF increase and 5 ns trr margin are acceptable |
Compared with STTH6006D and MUR460, the NUR460/L02,112 offers superior thermal resistance in axial package and tighter trr distribution-advantageous for EMI-critical, space-constrained PFC stages where layout-driven parasitics must be minimized.

FAQ
What is the maximum junction temperature rating for the NUR460/L02,112?
The NUR460/L02,112 has a maximum junction temperature (Tj) rating of 150 °C, verified per IEC 60134 limiting values. This allows operation in enclosed industrial environments without active cooling, provided PCB copper area and ambient conditions maintain junction temperature below this limit. Derating curves in Figure 1 and Figure 2 of the NXP datasheet define safe IF(AV) limits at elevated temperatures.
Does the NUR460/L02,112 have a soft recovery characteristic, and how is it implemented?
Yes, the NUR460/L02,112 features a soft recovery characteristic achieved via epitaxial silicon construction and optimized carrier lifetime control. This results in gradual minority-carrier removal during turn-off, minimizing voltage overshoot and di/dt-induced ringing. Measured trr values (25–65 ns) reflect controlled ramp/step recovery behavior, directly supporting low-EMI PFC and flyback designs without added snubbers.
What is the reverse leakage current specification for the NUR460/L02,112 at rated voltage and temperature?
At VR = 600 V and Tj = 25 °C, the NUR460/L02,112 exhibits a maximum reverse current (IR) of 50 µA, as specified in Table 6 of the NXP datasheet. This low leakage supports stable bus voltage hold-up in high-impedance PFC outputs and reduces standby power loss in energy-efficient adapters.
Is the NUR460/L02,112 suitable for automotive applications?
No-the NUR460/L02,112 is not automotive-qualified. Per NXP's legal disclaimers, it is intended for industrial and commercial power supplies only. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond 150 °C junction. For automotive use, engineers must select explicitly qualified alternatives such as NXP's automotive-grade diode families.
How does the forward voltage of the NUR460/L02,112 change with junction temperature?
The NUR460/L02,112 forward voltage decreases with rising junction temperature: VF = 1.28 V at 4 A/25 °C, and 0.88–1.05 V at 4 A/150 °C (Table 6). This negative temperature coefficient improves thermal stability in parallel configurations and maintains conduction efficiency under sustained load in thermally constrained enclosures.
