Product details
Overview
PNS40010AER-QX from Nexperia is a 400 V, 1 A standard-recovery surface-mount rectifier diode in SOD123W (CFP3) package, designed for automotive-grade general-purpose rectification and reverse polarity protection. It delivers low forward voltage (0.93 V typ. at 1 A, 25 °C), low reverse leakage (0.001 µA typ. at 400 V, 25 °C), and fast reverse recovery time (0.5–1.5 µs), enabling efficient power conversion in space-constrained DC/DC and battery management circuits.
For engineers reviewing the PNS40010AER-QX datasheet, PNS40010AER-QX pinout, PNS40010AER-QX application, or PNS40010AER-QX equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, 1 mm profile height, and compatibility with reflow/wave soldering-critical for under-hood automotive modules, industrial power supplies, and high-reliability embedded systems.
Technical Context
This standard-recovery rectifier uses high-efficiency planar silicon technology to achieve stable forward conduction and controlled reverse recovery behavior. Its 0.5–1.5 µs trr supports moderate-frequency switching (e.g., <100 kHz) while maintaining low EMI and thermal stress during commutation.
The device operates across –40 °C to +175 °C junction temperature, with thermal resistance Rth(j-sp) of 15 K/W to cathode solder point-enabling high-power-density layouts on FR4 PCBs with minimal copper area. Its 1.3 W total power dissipation (at Tamb ≤ 25 °C, 1 cm² cathode pad) supports sustained 1 A average current in thermally optimized designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V repetitive peak reverse voltage - ensures reliable blocking in 24 V/48 V automotive systems with load-dump transients. |
| IF(AV) | 1 A average forward current - supports continuous rectification in compact 5–10 W power rails without forced cooling. |
| VF @ 1 A, 25 °C | 0.93 V typical forward voltage - reduces conduction loss to ~0.93 W per diode, improving efficiency in low-voltage DC/DC stages. |
| IR @ 400 V, 25 °C | 0.001 µA typical reverse leakage - minimizes standby power loss in always-on vehicle subsystems. |
| trr | 0.5–1.5 µs reverse recovery time - balances switching speed and EMI for non-resonant flyback and buck converter freewheeling paths. |
| Rth(j-sp) | 15 K/W thermal resistance to solder point - enables direct thermal coupling to PCB copper, simplifying thermal design in tight spaces. |
| Tj(max) | 175 °C maximum junction temperature - meets under-hood automotive thermal requirements without derating at ambient up to 125 °C. |
Pinout & Package
Encapsulated in a compact SOD123W (CFP3) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm, with flat leads optimized for automated assembly and low-profile mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to output/positive rail side; primary heat path via cathode tab to PCB copper. |
| 2 (A) | Anode | Connected to input/negative rail side; carries full forward current during conduction phase. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and ADAS power supplies. |
| Low-profile SOD123W package | 1.0 mm max height enables use in ultra-thin modules and stacked PCB assemblies. |
| Reflow- and wave-solder compatible | Withstands JEDEC-standard reflow profiles and traditional wave soldering without delamination or parametric shift. |
| High power capability | Rated for 1.4 A peak forward current and 30 A non-repetitive surge, supporting transient overload conditions. |
| Low diode capacitance | 6–15 pF at 4 V reverse bias - minimizes capacitive switching losses and RF noise coupling in high-frequency circuits. |
Applications
| Automotive Body Control Module (BCM) | Industrial 24 V DC Power Supply |
|---|---|

IC Role / Device Role / Timing Role: General-purpose rectifier converting transformer secondary to DC bus for meter SoC and RTC. Use Value: Ultra-low IR (0.001 µA typ.) prevents battery drain in backup power circuits, extending supercapacitor hold-up time by 3×. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1H100SF | 100 V VRRM, Schottky architecture, VF = 0.55 V @ 1 A - lower conduction loss but limited to ≤100 V systems. | Not suitable for 400 V automotive load-dump environments; requires redesign of clamping network. | Select only if system reverse voltage stays below 80 V and efficiency at light load is critical. |
| ONsemi MUR110E | 100 V VRRM, ultrafast recovery (trr = 50 ns), TO-220AC package - faster switching but larger footprint and no AEC-Q101 rating. | Requires mechanical mounting and heatsinking; not qualified for automotive vibration or thermal cycling. | Prefer for non-automotive 100 V SMPS where EMI-sensitive high-frequency operation is required. |
Compared with STPS1H100SF and MUR110E, the PNS40010AER-QX uniquely combines 400 V blocking, AEC-Q101 compliance, and SOD123W form factor-making it the only drop-in solution for space-constrained, high-reliability 24/48 V automotive rectification without trade-offs in voltage rating or qualification.

FAQ
Is PNS40010AER-QX suitable for reflow soldering?
Yes. The device is qualified for both lead-free reflow soldering (per JEDEC J-STD-020) and wave soldering. Its SOD123W package withstands peak temperatures up to 260 °C for 10 seconds, and the recommended stencil thickness is 0.1 mm for optimal paste deposition and void-free joints.
What is the maximum average forward current at 100 °C ambient temperature?
At Tamb = 100 °C on an FR4 PCB with a 1 cm² cathode pad, the PNS40010AER-QX supports 0.85 A average forward current (δ = 0.5, f = 20 kHz square wave), as confirmed by Figure 9 in the datasheet. Derating is linear from 1 A at 25 °C to zero at 175 °C.
Does PNS40010AER-QX have a specified junction-to-case thermal resistance?
No. The datasheet specifies Rth(j-sp) = 15 K/W (junction-to-solder-point) and Rth(j-a) = 115 K/W (junction-to-ambient, with 1 cm² cathode pad), but does not define a discrete case interface. Thermal design must reference the solder point as the primary heat transfer node.
How does reverse recovery time vary with temperature?
trr increases with junction temperature: at Tj = 125 °C, trr rises to 0.7–1.8 µs (vs. 0.5–1.5 µs at 25 °C), per test conditions in Table 7. This is due to increased minority carrier lifetime, and must be accounted for in EMI filter sizing for high-temperature operation.
