Product details
Overview
PNU65020EPX from Nexperia is a 650 V, 2 A ultrafast recovery rectifier in CFP5 (SOD128) surface-mount package, designed for high-efficiency AC/DC conversion and freewheeling in power supplies. It delivers 35 ns typical reverse recovery time, 0.87 V forward voltage at 2 A and 125 °C, and operates up to 175 °C junction temperature - enabling compact, thermally robust designs in SMPS and battery chargers.
For engineers reviewing the PNU65020EPX datasheet, PNU65020EPX pinout, PNU65020EPX application, or PNU65020EPX equivalent, key selection criteria include ultrafast trr performance under high dIF/dt conditions, low VF across temperature, stable IR leakage at 125 °C, and thermal resistance optimization via clip-bonded cathode tab mounting.
Technical Context
This planar Pt-doped silicon rectifier uses lifetime-controlled carrier recombination to achieve ultrafast switching with minimal reverse recovery charge (Qrr = 32 nC) and low peak reverse recovery current (IRM = 1.7 A). Its step-recovery trr of 35 ns is specified at IF = 0.5 A, IR = 1 A, and IR(meas) = 0.25 A, Tj = 25 °C.
The device integrates a low-inductance, flat-lead SMD structure with clip-bond technology enhancing thermal conduction from die to solder point (Rth(j-sp) = 8 K/W), while its 21 pF diode capacitance at VR = 4 V supports high-frequency operation without excessive ringing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Withstands repetitive peak reverse voltage in high-voltage DC bus applications without breakdown. |
| IF(AV) | 2 A - Sustains average forward current in continuous conduction mode SMPS with δ = 0.5, f = 20 kHz square wave. |
| trr (typ) | 35 ns - Enables high-frequency switching (>100 kHz) with minimal switching loss and EMI generation. |
| VF @ 2 A, 125 °C | 0.87 V - Reduces conduction loss and thermal stress in high-temperature battery charger and UPS designs. |
| IR @ 650 V, 125 °C | 0.76 µA - Ensures low leakage in high-impedance hold-up circuits and improves system efficiency at elevated temperatures. |
| Rth(j-sp) | 8 K/W - Delivers efficient heat transfer from junction to cathode solder point, supporting high-power density layouts. |
| Qrr | 32 nC - Limits energy dissipation during turn-off, critical for ZVS/ZCS soft-switching topologies. |
Pinout & Package
Encapsulated in CFP5 (SOD128) - a compact 3.8 mm × 2.6 mm × 1.0 mm surface-mount plastic package with flat, power-optimized leads and clip-bonded cathode tab for low thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K (cathode) | Main current exit path; clip-bonded to large copper pad for enhanced thermal and current handling. |
| 2 | A (anode) | Current entry terminal; optimized for low-inductance routing in high-dI/dt freewheeling paths. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 35 ns trr enables >100 kHz switching in PFC and LLC resonant converters without excessive loss. |
| Planar Pt-doped die | Controlled carrier lifetime ensures consistent trr and Qrr across temperature and production lots. |
| Clip-bond construction | Reduces Rth(j-sp) to 8 K/W, allowing higher sustained current on standard FR4 PCBs with 1 cm² cathode pad. |
| Low forward voltage | 0.87 V at 2 A/125 °C lowers conduction loss by ~15% vs. comparable 650 V rectifiers at operating temperature. |
| Low diode capacitance | 21 pF at 4 V reverse bias minimizes capacitive turn-on loss and improves EMI profile in high-frequency SMPS. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | 600 V VRRM, 35 ns trr, VF = 1.15 V @ 2 A/125 °C, TO-220AC package | Higher VF increases conduction loss; through-hole mounting limits board-level power density | Select when legacy through-hole layout or higher IFSM (75 A) is required over thermal efficiency. |
| ON Semiconductor MUR260 | 600 V VRRM, 60 ns trr, VF = 1.05 V @ 2 A/125 °C, DO-41 package | Slower recovery increases switching loss in >50 kHz designs; axial lead limits automated assembly | Choose only for cost-sensitive, low-frequency (<30 kHz), non-SMT applications where footprint is not constrained. |
Compared with STTH2R06 and MUR260, PNU65020EPX offers superior thermal performance (Rth(j-sp) = 8 K/W), lower VF at operating temperature, and SMT compatibility - making it optimal for high-density, high-frequency, and thermally constrained power converter designs.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PNU65020EPX has a rated maximum junction temperature of 175 °C. It achieves this rating using planar Pt-doped silicon and clip-bond thermal architecture, enabling reliable operation in high-ambient environments such as enclosed battery chargers and server PSUs when mounted on a 1 cm² cathode pad per datasheet condition [2].
Does PNU65020EPX support reflow soldering, and what footprint is recommended?
Yes - PNU65020EPX is qualified for lead-free reflow soldering. The recommended footprint is defined in Figure 16 of the datasheet: 4.4 mm × 2.1 mm solder lands with 2.5 mm × 3.4 mm solder paste stencil opening, matching the CFP5 (SOD128) outline and ensuring robust thermal and mechanical attachment of the clip-bonded cathode.
How does the 35 ns trr value translate to real-world switching loss reduction?
At 100 kHz switching frequency and 1 A reverse recovery current, the 35 ns trr reduces stored charge dissipation by ~30% versus a 60 ns diode, cutting turn-off energy loss from ~1.8 µJ to ~1.3 µJ per cycle - directly improving efficiency by 0.3–0.5% in 200–500 W SMPS designs.
Is PNU65020EPX automotive-qualified?
No - PNU65020EPX is not automotive-qualified. It is specified for industrial and consumer power applications. Nexperia explicitly states in Section 15 of the datasheet that non-automotive qualified products are neither tested nor warranted for automotive use, including AEC-Q101 stress testing or PPAP documentation.
