Product details
Overview
PNE20040EPX from Nexperia is a hyperfast switching recovery rectifier optimized for high-frequency power conversion, reverse polarity protection, and freewheeling in compact SMD designs. It delivers 200 V repetitive peak reverse voltage, 4 A average forward current, ≤30 ns reverse recovery time, and low 720–780 mV forward voltage at 4 A and 125 °C - enabling efficient operation in DC-DC converters and motor drive snubbers.
For engineers reviewing the PNE20040EPX datasheet, PNE20040EPX pinout, PNE20040EPX application, or PNE20040EPX equivalent, key selection criteria include trr ≤30 ns for minimal switching loss, clip-bond thermal performance (Rth(j-sp) = 115 K/W), SOD128 package compatibility with automated assembly, and Pt-doped lifetime control for stable recovery behavior across temperature.
Technical Context
This planar silicon rectifier uses platinum doping to precisely control carrier lifetime, achieving tightly specified reverse recovery characteristics (trr = 13–30 ns typ.) under step- and ramp-recovery test conditions (IF = 0.5 A, IR = 1 A, dIF/dt = 100 A/µs). Its junction-to-solder-point thermal resistance of 115 K/W enables 4 A continuous conduction on FR4 PCBs with 1 cm² cathode pad.
The device operates with low diode capacitance (55 pF at 4 V), low inductance layout, and high surge capability (80 A IFSM), making it suitable for high-dV/dt environments such as synchronous rectifier flyback snubbers and automotive body control modules requiring fast transient response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands repetitive reverse voltage up to 200 V without breakdown, supporting 12–48 V system inputs with margin. |
| IF(AV) | 4 A - Sustains 4 A average forward current at Tsp ≤ 158 °C, enabling compact 20–50 W power stages. |
| trr | ≤30 ns - Ultra-fast recovery minimizes switching losses and EMI in >100 kHz SMPS topologies. |
| VF @ 4 A, 125 °C | 720–780 mV - Low forward drop reduces conduction loss and thermal stress in thermally constrained layouts. |
| Rth(j-sp) | 115 K/W - Enables effective heat transfer from junction to solder point on standard FR4 with 1 cm² cathode pad. |
| Qrr | 9 nC - Low reverse recovery charge limits turn-off energy dissipation and improves efficiency in hard-switched circuits. |
| IRM | 1 A - Peak reverse recovery current remains controlled, easing gate driver design in synchronous configurations. |
Pinout & Package
Encapsulated in CFP5 (SOD128) - a 2-terminal, surface-mount plastic package measuring 3.8 mm × 2.6 mm × 1.0 mm with 4 mm lead pitch and flat leads for low-inductance mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Main current exit terminal; connected to PCB thermal pad for enhanced heat dissipation and low-inductance return path. |
| 2 (A) | Anode | Current entry terminal; routed with minimal trace length to reduce parasitic inductance in high-dI/dt paths. |
Key Features
| Feature | Design Value |
|---|---|
| Hyperfast trr ≤30 ns | Enables operation in >200 kHz switching converters while maintaining low EMI and reduced turn-off loss. |
| Clip-bond construction | Improves thermal conductivity and current handling vs. wire-bonded equivalents, supporting 5.6 A DC forward current. |
| Pt-doped lifetime control | Ensures consistent, predictable reverse recovery behavior across temperature and production lots. |
| Low Rth(j-a) = 185 K/W | Permits natural-convection cooling in space-constrained applications without forced airflow or heatsinks. |
| SOD128 footprint | Compatible with industry-standard reflow profiles and automated optical inspection (AOI) for high-yield manufacturing. |
Applications
| DC-DC Converter Output Rectification | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Secondary-side rectification in isolated 24 V input, 5–12 V output flyback or forward converters operating at 100–300 kHz. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; critical timing role in defining dead-time loss and output ripple. Use Value: 30 ns trr and 9 nC Qrr reduce switching loss by ≥15% vs. standard fast recovery diodes, improving full-load efficiency by 0.8–1.2%. |
Use Scenario: Input protection circuit for industrial IoT nodes powered via 2-pin connectors where plug orientation is uncontrolled. IC Role / Device Role / Timing Role: Series blocking diode; conducts only during correct polarity insertion, with no active control required. Use Value: 200 V VRRM provides 4× margin over 48 V nominal systems, and 80 A IFSM withstands hot-plug inrush transients. |
| Motor Drive Freewheeling | High-Frequency Snubber Network |
|
Use Scenario: Freewheeling path for brushed DC motor H-bridge drivers in battery-powered power tools (18–36 V). IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when PWM switches turn off; timing-critical for minimizing voltage spikes. Use Value: 720–780 mV VF at 125 °C ensures <1.2 W conduction loss at 4 A, reducing thermal load on small PCB areas. |
Use Scenario: RC snubber across MOSFET drain-source in resonant LLC converters operating at 300–500 kHz. IC Role / Device Role / Timing Role: Fast-recovery clamp diode limiting dv/dt-induced ringing; timing role defined by trr and Qrr. Use Value: 55 pF capacitance and ≤30 ns trr suppress high-frequency oscillations without adding excessive capacitive loading to the switch node. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH4L06D | 600 V VRRM, 4 A IF(AV), trr = 35 ns, TO-277 package (larger, higher Rth(j-a)) | Higher voltage rating suits 400 V bus applications; less suitable for space-constrained 24–48 V designs due to larger footprint. | Select when system requires >200 V reverse margin or legacy through-hole compatibility is needed. |
| ON Semiconductor MUR420 | 200 V VRRM, 4 A IF(AV), trr = 35 ns, DO-214AC (SMA) package, higher VF (≥1.15 V @ 4 A) | Higher forward drop increases conduction loss; SMA package lacks thermal pad, limiting power density. | Choose only if SOD128 footprint is unavailable and thermal derating to ≤2.8 A is acceptable. |
Compared with STTH4L06D and MUR420, PNE20040EPX offers superior power density (SOD128 + clip-bond), lowest VF at elevated temperature, and tightest trr distribution - making it optimal for miniaturized, high-efficiency 24–48 V power supplies where thermal and EMI constraints are stringent.

FAQ
What is the maximum junction temperature for continuous operation?
The PNE20040EPX has a rated maximum junction temperature of 175 °C, validated per IEC60134 absolute maximum ratings. Operation at this limit requires thermal design ensuring Rth(j-sp) ≤115 K/W - typically achieved using a 1 cm² copper pad on FR4 with tin plating and standard reflow profile.
Does PNE20040EPX support wave soldering?
Yes - Nexperia provides dedicated wave soldering footprint data (Fig. 20) for the SOD128 package, specifying 4.2 mm × 2× dummy tracks, 5.7 mm overall length, and 3.65 mm × 2× solder lands. Thermal profiling must avoid exceeding 260 °C peak for ≤10 seconds to prevent delamination.
How does Pt doping affect reliability in high-temperature operation?
Pt doping stabilizes minority carrier lifetime across temperature, resulting in consistent trr and Qrr values from –40 °C to 125 °C. Accelerated life testing shows <0.5% parameter shift after 1000 hours at 150 °C, confirming suitability for extended-life industrial deployments.
Is the marking code 'ET' sufficient for full traceability?
Yes - 'ET' is the official Nexperia marking for PNE20040EPX (per Table 4), and each reel includes full lot traceability including wafer ID, assembly date, and test data. Aetrix Electronics provides full material traceability documentation upon request for audit-compliant builds.
