Product details
Overview
PNS40010AERX from Nexperia is a high-power-density standard-recovery surface-mount rectifier diode in SOD123W (CFP3) package, rated for 400 V repetitive peak reverse voltage and 1 A average forward current. It delivers low forward voltage (0.93 V typ. at 1 A, 25 °C), low reverse leakage (1 µA max at 400 V, 25 °C), and fast reverse recovery time (0.5–1.5 µs), enabling efficient general-purpose rectification and reverse polarity protection in space-constrained power supplies.
For engineers reviewing the PNS40010AERX datasheet, PNS40010AERX pinout, PNS40010AERX application, or PNS40010AERX equivalent, key selection criteria include thermal resistance (115 K/W junction-to-solder-point), 1 mm profile height, reflow/wave solder compatibility, and performance across -40 °C to +175 °C junction temperature range.
Technical Context
This planar-technology standard-recovery rectifier operates with fixed anode–cathode polarity and exhibits defined transient thermal impedance (15 K/W to solder point) and low diode capacitance (6–15 pF at 4 V). Its recovery behavior follows step- and ramp-defined trr test conditions per IEC standards, with IR(meas) set at 0.25 A during reverse recovery measurement.
The device uses a single-junction silicon die in a molded plastic SMD package with flat leads optimized for thermal conduction via cathode pad. It supports DC and pulsed operation up to 30 A non-repetitive peak forward current (8.3 ms half-sine), with derating governed by ambient and solder-point temperature limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in AC/DC bridge or flyback clamp circuits. |
| IF(AV) | 1 A - Average forward current at Tsp ≤ 166 °C; defines continuous DC output capability in linear or low-frequency switching supplies. |
| VF @ 1 A, 25 °C | 0.93 V (typ.) - Forward voltage drop determines conduction loss and self-heating; enables <1 W dissipation at full load on FR4 PCB. |
| trr | 0.5–1.5 µs - Reverse recovery time impacts switching losses and EMI in 20 kHz square-wave applications; qualifies as standard-speed (not ultrafast). |
| Rth(j-sp) | 115 K/W - Thermal resistance from junction to solder point; enables 1.3 W total power dissipation with 1 cm² cathode copper pad. |
| Cd @ 4 V | 6–15 pF - Junction capacitance affects high-frequency noise coupling and snubber design in SMPS input stages. |
| IR @ 400 V, 25 °C | 1 µA (max) - Low reverse leakage preserves efficiency in high-impedance bias networks and reverse-blocking configurations. |
Pinout & Package
Package: SOD123W (CFP3), surface-mount plastic package with 2.6 mm × 1.7 mm × 1.0 mm body and 1 mm typical height; optimized for automated assembly and thermal transfer via cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to negative output or ground return path; primary thermal interface-requires ≥1 cm² copper pad for rated power handling. |
| 2 (A) | Anode | Connected to AC input or positive rail; carries forward current; minimal thermal contribution compared to cathode. |
Key Features
| Feature | Design Value |
|---|---|
| High power density | 1 A / 1 mm height enables compact layout in USB-C PD adapters, LED drivers, and industrial AC-DC modules. |
| Low forward voltage | 0.93 V typ. at 1 A reduces conduction loss by ~15% vs. legacy 1N4007 in same footprint, improving thermal margin. |
| Standard switching time | 0.5–1.5 µs trr supports 20 kHz square-wave rectification without excessive ringing-ideal for offline SMPS secondary-side use. |
| Reflow/wave solder compatible | Qualified per J-STD-020; withstands peak reflow temperatures up to 260 °C, ensuring robust manufacturing yield. |
| Low reverse leakage | 1 µA max at 400 V, 25 °C ensures stable blocking in battery backup paths and reverse-polarity protection circuits. |
Applications
| AC-DC Power Supply Rectification | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Secondary-side rectification in 5–24 V, 10–30 W offline flyback converters. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC; operates at line frequency or 20–100 kHz switching frequency. Use Value: 0.93 V forward drop minimizes heat generation in confined enclosures; 1 mm height allows stacked PCB designs. |
Use Scenario: Input protection for 12 V/24 V industrial controllers powered from external DC sources. IC Role / Device Role / Timing Role: Series-blocking diode preventing damage when supply polarity is accidentally reversed. Use Value: 1 µA max reverse leakage avoids standby current drain; 400 V rating covers surge transients per IEC 61000-4-5. |
| DC-DC Converter Output Stage | Capacitor Charging Circuit |
|
Use Scenario: Output rectification in isolated 48 V → 12 V forward converters for telecom equipment. IC Role / Device Role / Timing Role: Freewheeling path during MOSFET off-time; handles 20 kHz square-wave current with defined trr. Use Value: 115 K/W Rth(j-sp) enables 1.3 W dissipation with minimal board area; low Cd suppresses high-frequency oscillation. |
Use Scenario: Charging hold capacitors in energy-harvesting nodes and backup power systems. IC Role / Device Role / Timing Role: Isolation diode preventing capacitor discharge back into source during intermittent charging cycles. Use Value: 175 °C max junction temperature supports operation in sealed enclosures; low IR preserves stored charge over days. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard-recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1H100S | Same 100 V rating but lower VRRM; Schottky architecture yields 0.55 V VF, no reverse recovery. | Not suitable for 400 V line-referenced circuits; preferred where low VF outweighs reverse leakage sensitivity. | Select only if system reverse voltage never exceeds 100 V and ultra-low conduction loss is critical. |
| ON Semi MUR120 | Higher 200 V VRRM, TO-220 package; faster trr (≤75 ns), higher IF(AV) (1 A), but larger footprint and 4.5 mm height. | Requires through-hole assembly and heatsinking; unsuitable for ultra-thin SMT-only designs. | Choose when board-level thermal management permits TO-220 mounting and 200 V rating suffices. |
Compared with STPS1H100S and MUR120, PNS40010AERX uniquely balances 400 V rating, 1 mm profile, and standard-speed recovery in a low-cost SOD123W package-making it optimal for cost-sensitive, space-constrained 20 kHz rectification where Schottky leakage or TO-220 size are unacceptable.

FAQ
What is the maximum allowable solder point temperature for PNS40010AERX during reflow?
The device is qualified for standard reflow profiles per J-STD-020, with peak temperature up to 260 °C. The absolute maximum solder point temperature is not specified separately, but thermal design must ensure Tsp ≤ 166 °C during steady-state operation to maintain 1 A IF(AV) rating. Exceeding this limit causes irreversible derating of forward current capability.
Can PNS40010AERX replace a 1N4007 in existing designs?
Yes, but with caveats: PNS40010AERX matches the 1N4007's 1 A / 1000 V rating only partially-it offers identical 1 A average current but lower 400 V VRRM. Its SOD123W footprint is incompatible with axial 1N4007; replacement requires PCB redesign. However, its lower VF and superior thermal performance justify migration in new SMT-based 400 V-class designs.
Does PNS40010AERX have automotive qualification?
No. Per Nexperia's legal disclaimers, PNS40010AERX is explicitly designated as non-automotive qualified. It has not undergone AEC-Q101 stress testing or been validated for automotive temperature ranges, reliability requirements, or failure mechanisms. Use in automotive applications is unsupported and at the customer's sole risk.
How does reverse recovery time affect EMI in a 20 kHz SMPS design?
At 20 kHz, PNS40010AERX's 0.5–1.5 µs trr generates moderate dI/dt during turn-off, contributing to high-frequency ringing (typically 1–10 MHz) that couples into input/output filters. This necessitates careful snubber placement and layout-especially minimizing loop inductance around the cathode pad-to meet CISPR-22 Class B conducted emissions limits without oversizing filter components.
