Product details
Overview
PNE20020EXDX from Nexperia is a hyperfast recovery rectifier diode designed for high-efficiency, high-frequency switching applications in compact SMD power supplies and DC-DC converters. It delivers 200 V reverse voltage rating, 2 A average forward current, ≤25 ns reverse recovery time, and low 950 mV forward voltage at 2 A - enabling reduced conduction and switching losses in freewheeling and reverse polarity protection circuits.
For engineers reviewing the PNE20020EXDX datasheet, PNE20020EXDX pinout, PNE20020EXDX application, or PNE20020EXDX equivalent, key selection criteria include its CFP2-HP (SOD323HP) package height of 0.68 mm, Pt-doped planar die for stable trr, clip-bond thermal performance, and validated operation up to 175 °C junction temperature.
Technical Context
This device employs a platinum-doped planar silicon die with lifetime control to achieve consistent hyperfast recovery behavior under dynamic load conditions. Its trr is specified at ≤25 ns using step-recovery test conditions (IF = 0.5 A, IR = 1 A, IR(meas) = 0.25 A, Tj = 25 °C), with ramp-recovery trr ≤15 ns and Qrr = 4 nC at IF = 1 A, dIF/dt = 50 A/µs, VR = 30 V.
The CFP2-HP package integrates a copper clip-bond structure that lowers thermal resistance to 6 K/W (junction-to-solder-point), enabling higher power density than standard SOD323 devices. It maintains rated IF(AV) = 2 A at Tsp ≤ 163 °C with δ = 0.5 square-wave excitation at 20 kHz, supported by low-inductance layout and flat lead geometry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 200 V - supports input rectification in 100–120 VAC SMPS front-ends and 48 V industrial bus protection. |
| Average Forward Current (IF(AV)) | 2 A - sustains continuous conduction in high-duty-cycle freewheeling paths without derating below 163 °C solder point. |
| Reverse Recovery Time (trr) | ≤25 ns - minimizes switching loss and EMI in >100 kHz DC-DC topologies such as synchronous buck and flyback. |
| Forward Voltage (VF) | 950 mV typ. at 2 A, 25 °C - reduces conduction loss versus standard fast rectifiers (e.g., ~1.1 V), improving efficiency at medium loads. |
| Junction Temperature (Tj) | 175 °C max - enables reliable operation in thermally constrained environments like sealed LED drivers or motor control PCBs. |
| Thermal Resistance (Rth(j-sp)) | 125 K/W (FR4, 1 cm² cathode pad) - allows 1.2 W dissipation at Tamb ≤ 25 °C, supporting compact heatsinkless designs. |
| Diode Capacitance (Cd) | 10 pF at VR = 4 V, 1 MHz - limits capacitive turn-on loss and improves high-frequency noise immunity in snubberless layouts. |
Pinout & Package
Encapsulated in the ultra-low-profile CFP2-HP (SOD323HP) surface-mount plastic package measuring 2.2 mm × 1.3 mm × 0.68 mm, this rectifier uses a clip-bond construction for enhanced thermal and electrical performance over conventional wire-bonded SOD323 variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main current exit terminal; connected to internal clip-bond tab for low-inductance, low-resistance path and direct thermal conduction to PCB. |
| 2 | Anode (A) | Main current entry terminal; bonded via fine-wire or embedded metallization; optimized for minimal parasitic inductance in high-dI/dt paths. |
Key Features
| Feature | Design Value |
|---|---|
| Hyperfast recovery | trr ≤ 25 ns ensures minimal reverse recovery charge (Qrr = 4 nC), reducing switching loss and voltage overshoot in hard-switched converters. |
| Planar Pt-doped die | Provides tightly controlled, temperature-stable trr across -40 °C to 175 °C, eliminating variability seen in diffusion-controlled diodes. |
| Clip-bond technology | Reduces Rth(j-sp) to 6 K/W at cathode solder point, enabling 25 A non-repetitive surge handling (IFSM) and improved power cycling reliability. |
| Low-profile SMD package | 0.68 mm height and 2.2 mm × 1.3 mm footprint allow placement beneath connectors or in ultra-thin power modules without mechanical interference. |
| Low forward voltage | 950 mV typ. at 2 A, 25 °C lowers conduction loss by ~15% vs. legacy 2 A fast rectifiers, directly improving light-load efficiency. |
Applications
| AC-DC Adapter Output Rectification | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Secondary-side rectification in 12–24 V, 20–40 W wall adapters using quasi-resonant flyback topology. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; must recover before next switching cycle to avoid shoot-through. Use Value: 25 ns trr prevents reverse recovery overlap with primary switch turn-on, eliminating cross-conduction loss and reducing EMI filter size. |
Use Scenario: Input protection for USB-C PD power delivery modules where miswired cables could apply reversed 20 V input. IC Role / Device Role / Timing Role: Series blocking diode placed between connector and DC-DC input; conducts only during correct polarity insertion. Use Value: 200 V VR rating provides 2× safety margin over 20 V max input, while 2 A IF(AV) handles peak 1.8 A PD3.1 loads without thermal derating. |
| DC-DC Buck Converter Freewheeling | Motor Driver Flyback Clamping |
|
Use Scenario: High-frequency (500 kHz) 5 V/3 A buck converter powering FPGA I/O rails in industrial PLC modules. IC Role / Device Role / Timing Role: Synchronous rectifier replacement operating in discontinuous conduction mode (DCM); recovers within <100 ns dead time. Use Value: Low Qrr (4 nC) and 950 mV VF reduce total power loss by 0.35 W vs. standard fast diode, lowering local PCB temperature rise by 12 °C. |
Use Scenario: Clamp diode across brushed DC motor terminals in battery-powered power tools to suppress inductive kick during PWM commutation. IC Role / Device Role / Timing Role: Transient energy sink during MOSFET turn-off; must conduct rapidly to limit VDS spike to <200 V. Use Value: 25 A IFSM rating absorbs 10 ms motor stall surges, while 25 ns trr prevents delayed conduction that would cause MOSFET avalanche stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EY20-M3 | Same 200 V/2 A rating but TO-277 package (4.5 mm × 3.5 mm × 1.1 mm); trr = 35 ns; VF = 1.05 V @ 2 A. | Larger footprint and 40% higher height limit use in ultra-thin designs; higher VF increases conduction loss by ~110 mW. | Select when board space permits and higher surge robustness (IFSM = 40 A) is prioritized over profile and efficiency. |
| ON Semiconductor MUR220SFT1G | SOD-123FL package (3.7 mm × 1.7 mm × 1.0 mm); trr = 30 ns; VF = 1.02 V @ 2 A; Tj = 175 °C. | Higher VF and 0.32 mm greater height reduce power density; slower trr increases switching loss in >300 kHz designs. | Choose for legacy SOD-123 footprint compatibility where minor efficiency and EMI trade-offs are acceptable. |
Compared with VS-2EY20-M3 and MUR220SFT1G, PNE20020EXDX offers the lowest profile (0.68 mm), fastest trr (≤25 ns), and lowest VF (950 mV), making it optimal for space-constrained, high-frequency, and efficiency-critical freewheeling and clamping roles.

FAQ
What is the maximum allowable solder point temperature for PNE20020EXDX during reflow?
The device supports peak reflow temperatures up to 260 °C for ≤30 seconds per J-STD-020, with maximum solder point temperature limited to 163 °C under continuous 2 A operation (δ = 0.5, f = 20 kHz). Exceeding 163 °C at the cathode solder point causes irreversible IF(AV) derating per Figure 10.
Does PNE20020EXDX require a heatsink in typical 2 A applications?
No external heatsink is required when mounted on an FR4 PCB with a 1 cm² cathode copper pad: Rth(j-sp) = 125 K/W enables full 2 A IF(AV) at Tamb ≤ 25 °C. With standard footprint (no extended pad), derating begins above Tamb = 45 °C per Figure 8.
How does the Pt-doped planar process improve reliability versus standard fast rectifiers?
Platinum doping provides precise carrier lifetime control, resulting in stable trr across temperature (-40 °C to 175 °C) and current (0.1–2 A), eliminating erratic recovery behavior and thermal runaway risks common in gold-diffused or uncontrolled diffusion diodes.
Can PNE20020EXDX replace Schottky diodes in 200 V applications?
No - Schottky diodes lack 200 V capability; the highest-voltage commercial Schottkys are ~170 V. PNE20020EXDX is a silicon PN junction rectifier optimized for 200 V hyperfast operation where Schottkys cannot function, offering superior VR rating and temperature stability versus lower-VF alternatives.
