Product details
Overview
PNE20020AER-QX from Nexperia is a 200 V, 2 A hyperfast recovery rectifier in CFP3 (SOD123W) package, designed for high-efficiency automotive power conversion. It delivers trr ≤ 25 ns reverse recovery time, VF = 735–820 mV at 2 A / 125 °C, and is qualified to AEC-Q101 for under-hood DC/DC converters and motor control freewheeling paths.
For engineers reviewing the PNE20020AER-QX datasheet, PNE20020AER-QX pinout, PNE20020AER-QX application, or PNE20020AER-QX equivalent, key selection criteria include hyperfast switching performance, low forward voltage at elevated junction temperature, AEC-Q101 qualification, and thermal resistance Rth(j-sp) = 105 K/W on FR4 with cathode pad.
Technical Context
This planar silicon rectifier uses Pt-doped lifetime control to achieve sub-25 ns trr while maintaining low VF and high IRM tolerance. Its clip-bond construction enhances thermal transfer and current handling beyond standard SOD123W devices.
The device operates across Tj = −40 °C to 175 °C, supports reflow and wave soldering, and exhibits stable reverse leakage (IR ≤ 10 µA at 125 °C / 200 V), enabling reliable operation in automotive transients and high-temperature engine compartments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; enables use in 12 V/24 V automotive systems with 100 V+ transient margin. |
| IF(AV) | 2 A - Average forward current at δ = 0.5 / 20 kHz square wave with Tsp ≤ 164 °C; supports continuous conduction in compact DC/DC stages. |
| trr | 10–25 ns - Measured step recovery time; minimizes switching losses and EMI in >100 kHz SMPS designs. |
| VF | 735–820 mV @ 2 A / 125 °C - Low forward drop reduces conduction loss and thermal stress in high-duty-cycle freewheeling paths. |
| Rth(j-sp) | 105 K/W - Junction-to-solder-point thermal resistance on FR4 with 1 cm² cathode pad; enables direct thermal coupling to PCB ground plane. |
| Qrr | 9 nC - Reverse recovery charge at IF = 1 A / dIF/dt = 100 A/µs; limits diode-induced voltage spikes during hard-switching transitions. |
| IRM | 1 A - Peak reverse recovery current; informs snubber sizing and MOSFET voltage stress during turn-on of synchronous rectifiers. |
Pinout & Package
Encapsulated in CFP3 (SOD123W) plastic SMD package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile optimized for automated assembly and thermal dissipation via cathode tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Main current exit terminal; large-area metal tab provides primary thermal path to PCB copper; must be connected to thermal pad per Fig. 19 footprint. |
| 2 (A) | Anode | Current entry terminal; smaller pad area; electrically isolated from cathode; connects to switching node or input rail. |
Key Features
| Feature | Design Value |
|---|---|
| Hyperfast recovery | trr ≤ 25 ns ensures minimal switching loss and reduced EMI in high-frequency (>200 kHz) buck and flyback topologies. |
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control units and ADAS power supplies. |
| Clip-bond construction | Enables 2.8 A DC forward current rating and improved thermal reliability vs. wire-bonded SOD123W equivalents. |
| Pt-doped lifetime control | Provides precise trr/VF trade-off without compromising softness or leakage-critical for noise-sensitive infotainment systems. |
| Reflow/wave solder compatible | Qualified for JEDEC J-STD-020D reflow profiles and wave soldering; eliminates assembly process risk in high-volume production. |
Applications
| Automotive DC/DC Converters | Motor Drive Freewheeling |
|---|---|
|
Use Scenario: Secondary-side rectification in 48 V–12 V bidirectional buck-boost converters for mild hybrid vehicles. IC Role / Device Role / Timing Role: High-efficiency unidirectional current path with minimal reverse recovery energy loss during high-frequency PWM switching. Use Value: 735 mV VF at 125 °C reduces conduction loss by ~18% vs. standard fast rectifiers, lowering thermal load on converter PCB. |
Use Scenario: Freewheeling path across brushed DC motor windings in electronic power steering (EPS) modules. IC Role / Device Role / Timing Role: Clamp inductive kickback during MOSFET turn-off; requires <25 ns trr to prevent voltage overshoot exceeding 200 V rating. Use Value: 10 ns minimum trr and 1 A IRM enable robust clamping without external snubbers, simplifying EPS board layout. |
| Reverse Polarity Protection | On-Board Charger Input Stage |
|
Use Scenario: Series-connected protection diode at battery input of automotive telematics control units (TCUs). IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage from accidental battery reversal during service. Use Value: 200 V VRRM withstands jump-start transients up to 160 V RMS; low VF avoids excessive voltage drop during cold-cranking conditions. |
Use Scenario: Input rectification stage in 6.6 kW AC/DC OBC front-end using Vienna rectifier topology. IC Role / Device Role / Timing Role: Fast-recovery diode in boost leg switching cells where trr directly impacts THD and efficiency. Use Value: 9 nC Qrr reduces reactive current burden on gate drivers and improves power factor correction linearity at 50/60 Hz input. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02AY | Same VRRM (200 V), IF(AV) = 2 A, but trr = 35 ns (typ); VF = 950 mV @ 2 A / 25 °C; no AEC-Q101 qualification. | Limited to industrial/non-automotive use; higher VF increases conduction loss in thermally constrained modules. | Select when AEC-Q101 is not required and cost is prioritized over thermal performance. |
| ON Semiconductor MUR220RLG | VRRM = 200 V, IF(AV) = 2 A, trr = 35 ns (max), VF = 950 mV @ 2 A / 25 °C; TO-220AC package (not SMD). | Requires through-hole assembly and heatsinking; unsuitable for space-constrained automotive modules. | Choose only if legacy through-hole design mandates TO-220 footprint and thermal mass outweighs size penalty. |
Compared with STTH2R02AY and MUR220RLG, PNE20020AER-QX offers superior trr (≤25 ns), lower VF at high temperature, AEC-Q101 compliance, and SMD CFP3 packaging-making it the only option qualified for next-generation automotive power electronics requiring miniaturization and thermal robustness.

FAQ
Is PNE20020AER-QX suitable for reflow soldering?
Yes. The device is qualified for JEDEC J-STD-020D-compliant reflow profiles, including peak temperatures up to 260 °C. Its CFP3 (SOD123W) package uses tin-plated leads and is validated for both leaded and lead-free processes per Figure 19 footprint guidelines.
What is the maximum ambient temperature for continuous 2 A operation?
At δ = 0.5 / 20 kHz square wave, the device supports 2 A average forward current up to Tamb = 105 °C on FR4 with 1 cm² cathode pad (Fig. 9). Above this, derating applies per the thermal curves in Figures 8–9; full 2 A requires Tsp ≤ 164 °C.
Does PNE20020AER-QX have a soft recovery characteristic?
No. As a Pt-doped hyperfast rectifier, it exhibits fast but not soft recovery: trr is tightly controlled (10–25 ns), and IRM reaches 1 A. Soft recovery is not specified; designers should verify EMI behavior in target circuits and consider RC snubbers if voltage ringing exceeds system limits.
Can PNE20020AER-QX replace standard fast recovery diodes in existing designs?
Yes-if the PCB footprint matches SOD123W and thermal design accommodates its 105 K/W Rth(j-sp). Its lower VF and faster trr improve efficiency and reduce EMI, but layout review is essential to confirm cathode pad area and solder joint integrity for optimal thermal performance.
