Product details
Overview
PNU65020EP-QX from Nexperia is a 650 V, 2 A ultrafast recovery rectifier in CFP5 (SOD128) surface-mount package, designed for high-efficiency power conversion in automotive-grade systems. It features 35 ns typical reverse recovery time, 0.87 V forward voltage at 2 A and 125 °C, Pt-doped lifetime control, and AEC-Q101 qualification - deployed in on-board chargers and DC/DC converters where fast switching and thermal robustness are critical.
For engineers reviewing the PNU65020EP-QX datasheet, PNU65020EP-QX pinout, PNU65020EP-QX application, or PNU65020EP-QX equivalent, key selection criteria include reverse recovery time (trr ≤ 65 ns), junction-to-solder-point thermal resistance (Rth(j-sp) = 8 K/W), peak reverse recovery current (IRM = 1.7 A), and AEC-Q101 qualification for automotive power electronics.
Technical Context
This planar silicon rectifier uses platinum doping to precisely control carrier lifetime, enabling ultrafast recovery with low Qrr (32 nC) and minimal VFRM (3.9 V). Its clip-bond construction enhances thermal conduction from die to cathode tab, supporting sustained 2 A average forward current at Tsp ≤ 160 °C.
The device operates with low diode capacitance (21 pF at 4 V), low inductance packaging, and stable reverse leakage (<1 µA at 650 V, 25 °C), making it suitable for high-frequency hard-switched topologies in EV traction auxiliary supplies and bidirectional DC/DC stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Withstands repetitive peak reverse voltage up to 650 V without breakdown, enabling use in 400 V DC bus systems with margin. |
| IF(AV) | 2 A - Sustains 2 A average forward current under square-wave conditions (δ = 0.5, f = 20 kHz) with solder point ≤ 160 °C. |
| trr | 35 ns (typ) - Ultrafast reverse recovery minimizes switching losses and EMI in high-frequency (>100 kHz) converters. |
| VF @ 2 A, 125 °C | 0.87 V (typ) - Low forward voltage reduces conduction loss and thermal stress in thermally constrained automotive modules. |
| Qrr | 32 nC - Low reverse recovery charge limits turn-off energy and snubber requirements in hard-switched applications. |
| Rth(j-sp) | 8 K/W - Junction-to-solder-point thermal resistance enables efficient heat transfer to PCB copper, critical for compact layouts. |
| AEC-Q101 | Qualified - Meets stress test requirements for discrete semiconductors in automotive applications including temperature cycling and HTRB. |
Pinout & Package
Encapsulated in CFP5 (SOD128) - a flat, power-optimized surface-mount plastic package measuring 3.8 mm × 2.6 mm × 1.0 mm with 4 mm lead pitch and exposed cathode tab for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main current exit terminal; large-area metal tab provides low-inductance path and primary thermal interface to PCB. |
| 2 | Anode (A) | Current entry terminal; smaller pad optimized for signal integrity and layout symmetry in bridge configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast trr | 35 ns typical - Enables operation in >200 kHz switching converters while maintaining low EMI and reduced snubber losses. |
| Clip-bond technology | Direct die-to-tab interconnect - Reduces thermal resistance by ~30% vs. wire-bond equivalents, improving power density and reliability. |
| Pt-doped lifetime control | Stable, reproducible trr and Qrr across temperature - Eliminates process drift and ensures consistent performance in automotive thermal cycles. |
| Low Rth(j-sp) | 8 K/W - Allows direct thermal coupling to copper pour, enabling 2 A operation without heatsink in space-constrained OBC modules. |
| AEC-Q101 qualification | Full stress test compliance - Validated for automotive under-hood environments including HTGB, HTRB, and temperature cycling (-40 °C to 150 °C). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06S | 600 V VRRM, 35 ns trr, TO-277 package (larger footprint, higher Rth(j-a)) | Lacks AEC-Q101 qualification; not recommended for automotive production | Select when cost sensitivity outweighs automotive qualification and board space is unconstrained. |
| ES1JHM3/84A | 600 V VRRM, 35 ns trr, SMA package (smaller size, lower IF(AV) = 1 A) | Lower current rating and no AEC-Q101 - suited for non-automotive consumer/industrial SMPS | Choose only for space-limited, sub-1 A applications where automotive qualification is unnecessary. |
Compared with STTH2R06S and ES1JHM3/84A, the PNU65020EP-QX uniquely combines 650 V rating, AEC-Q101 qualification, 2 A current capability, and CFP5 thermal performance - making it the only drop-in solution for automotive OBC and DC/DC secondary-side rectification requiring both reliability and power density.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PNU65020EP-QX has a maximum junction temperature (Tj) rating of 175 °C. Continuous operation at this limit requires strict thermal design - including ≥1 cm² copper pad under the cathode tab and controlled ambient/solder point temperature per Figure 9 and Figure 10 in the datasheet. Derating applies above 150 °C Tj.
Does the device support bidirectional current flow in reverse-conducting configurations?
No - the PNU65020EP-QX is a unidirectional ultrafast recovery rectifier. It conducts only from anode to cathode under forward bias and blocks up to 650 V in reverse. It is not rated for reverse conduction and lacks symmetrical characteristics required for RC-IGBT or reverse-conducting SiC diode replacement.
How does the CFP5 package compare thermally to TO-277 or SMA packages?
The CFP5 (SOD128) package delivers Rth(j-sp) = 8 K/W - significantly lower than TO-277 (~15 K/W) and SMA (~30 K/W) - due to its exposed cathode tab and clip-bond construction. This enables 2 A operation with minimal external copper, whereas TO-277 and SMA require larger thermal pads or heatsinks to achieve equivalent current handling.
Is the marking code 'EV' sufficient for full traceability in automotive production?
Yes - the 'EV' marking on PNU65020EP-QX corresponds to the full type number per Table 4 of the datasheet and is supported by Nexperia's automotive traceability system. Each reel includes lot-specific date codes and conforms to IATF 16949-compliant manufacturing records, enabling full material traceability back to wafer batch.
