Product details

Overview

NUR460P from NXP Semiconductors is an ultrafast power diode in DO-201AD (SOD141) axial package, rated for 600 V repetitive peak reverse voltage, 4 A average forward current, and 50 ns reverse recovery time. It serves as a high-frequency freewheeling or output rectifier in DCM PFC stages and SMPS secondary-side circuits.

For engineers reviewing the NUR460P datasheet, NUR460P pinout, NUR460P application, or NUR460P equivalent, this page delivers verified electrical parameters, thermal resistance (55 K/W), soft recovery behavior, cathode/anode terminal mapping, and direct alternatives for high-voltage switching diode selection.

Technical Context

The NUR460P employs a planar epitaxial silicon structure optimized for fast, soft reverse recovery-critical for minimizing EMI and voltage overshoot in discontinuous-mode PFC boost diodes. Its low leakage (≤10 µA at 600 V, 25 °C) and stable VF (0.82–1.05 V at 3 A, 150 °C) support reliable operation across industrial temperature ranges.

Thermal design is enabled by its 55 K/W junction-to-ambient resistance in free air and 175 °C maximum junction temperature. The device sustains non-repetitive surge currents up to 110 A (8.3 ms sine wave), supporting robust transient handling in AC/DC front-end designs.

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 V_RRM, 6 A I_F(AV), 60 ns t_rr, TO-220AC package	Higher current rating but larger footprint; requires heatsinking above 2.5 W	Select when higher average current or PCB-mount thermal management is needed

FAQ

What is the maximum junction temperature rating for the NUR460P?

The NUR460P has a maximum junction temperature (T_j) of 175 °C, enabling reliable operation in high-ambient environments such as enclosed industrial power supplies or thermally dense PCB layouts. This rating is validated per IEC 60134 limiting values and supports sustained conduction at full I_F(AV) with appropriate thermal design. The NUR460P must not exceed this limit during steady-state or transient conditions to ensure long-term reliability.

Does the NUR460P have a soft recovery characteristic, and why does it matter?

Yes, the NUR460P features a soft recovery characteristic, meaning its reverse current decay is gradual rather than abrupt during turn-off. This reduces voltage overshoot and high-frequency ringing in switching nodes-critical for meeting EMI standards in Class B power supplies. In DCM PFC circuits, soft recovery directly lowers snubber losses and simplifies filter design. The NUR460P's softness is inherent to its epitaxial structure and confirmed in Fig. 5 and Fig. 6 of its official datasheet.

What is the thermal resistance from junction to ambient for the NUR460P in free air?

The NUR460P has a typical thermal resistance from junction to ambient (R_th(j-a)) of 55 K/W when mounted in free air with no heatsink. This value allows estimation of junction temperature rise: T_j = T_amb + (P_diss × 55). For example, at 1.2 W dissipation and 50 °C ambient, T_j ≈ 116 °C-well within the 175 °C absolute maximum. The NUR460P's R_th(j-a) is measured per standard JEDEC test conditions for axial devices.

How does the forward voltage of the NUR460P vary with temperature and current?

The NUR460P's forward voltage decreases with rising junction temperature: it is 1.05 V (max) at 3 A and 150 °C, versus 1.25 V (max) at 3 A and 25 °C. This negative temperature coefficient improves thermal stability in parallel configurations. At 4 A and 25 °C, V_F reaches up to 1.28 V. These values are measured per Fig. 4 in the NUR460P datasheet and reflect actual silicon behavior-not extrapolated estimates. Designers should use the 150 °C curve for worst-case thermal analysis.

Is the NUR460P suitable for automotive applications?

No, the NUR460P is not automotive-qualified. Per NXP's legal disclaimers (Section 12.3), unless explicitly stated in the datasheet, the device is not tested or warranted for automotive use. It lacks AEC-Q101 qualification, and its production status is marked "Production" for industrial/commercial applications only. For automotive-grade alternatives, consult NXP's AEC-Q101-certified diode portfolio. The NUR460P remains appropriate for industrial, consumer, and computing power supplies where automotive reliability standards do not apply.
