Product details
Overview
PMEG4010CEJ-QX from Nexperia is a 40 V, 1 A automotive-qualified Schottky barrier rectifier in SOD323F (SC-90) package, featuring 490–570 mV forward voltage at 1 A, ≤50 µA reverse leakage at 40 V, and integrated guard ring for stress protection. It serves as a low-loss unidirectional power path in DC/DC converters, reverse polarity protection circuits, and low-voltage rectification stages.
For engineers reviewing the PMEG4010CEJ-QX datasheet, PMEG4010CEJ-QX pinout, PMEG4010CEJ-QX application, or PMEG4010CEJ-QX equivalent, key selection criteria include forward voltage consistency across temperature, AEC-Q101 qualification status, thermal resistance to solder point (150 K/W), and cathode-marked SOD323F footprint compatibility with high-density PCB layouts.
Technical Context
This MEGA Schottky rectifier uses planar silicon construction with an integrated guard ring to suppress edge breakdown under transient stress-critical for automotive load-dump and cold-crank conditions. Its low VF enables >92 % efficiency in 3.3 V/5 V buck converter outputs at 1 A.
The device operates with junction temperatures up to 150 °C and exhibits stable reverse leakage (<6 µA typical at 40 V, 25 °C) and diode capacitance (69–77 pF at 1 V, 1 MHz), supporting high-frequency switching up to 1 MHz without significant capacitive loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 490–570 mV at 1 A, pulsed - enables <0.57 W conduction loss in 5 V output rails |
| Reverse Voltage (VR) | 40 V maximum - supports 24 V automotive systems with 100 % margin over nominal bus |
| Reverse Leakage (IR) | ≤50 µA at 40 V, 25 °C - minimizes standby power loss in always-on modules |
| Diode Capacitance (Cd) | 69–77 pF at 1 V, 1 MHz - limits switching node ringing in >500 kHz SMPS designs |
| Junction-to-Solder-Point Rth | 150 K/W - allows 0.83 W dissipation with ≤125 °C rise above PCB solder point |
| AEC-Q101 Qualified | Yes - certified for automotive powertrain, body control, and infotainment applications |
| Package | SOD323F (SC-90), 1.7 × 1.25 × 0.7 mm - compatible with 0402-class reflow footprints |
Pinout & Package
Encapsulated in a surface-mount SOD323F (SC-90) plastic package with flat leads, the PMEG4010CEJ-QX features a 2-pin configuration where Pin 1 is cathode (marked by bar) and Pin 2 is anode. The package is optimized for thermal transfer via cathode pad and meets IPC-7351B standard land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; marked side of package; primary thermal path to PCB |
| 2 | Anode (A) | Input terminal for forward conduction; electrically isolated from cathode pad; no thermal coupling |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge breakdown during voltage transients-enables robust operation in automotive load-dump events |
| Very low VF profile | 490–570 mV @ 1 A ensures <0.57 W conduction loss at full rated current |
| AEC-Q101 qualification | Validated for automotive use per stress test requirements including HTGB, HTRB, and TCT |
| Small SOD323F footprint | 1.7 × 1.25 mm area saves >40 % board space vs. SOD123 in high-density power modules |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-40TF | Higher VF (600–700 mV @ 1 A); same 40 V VR; TO-236AB (SOT-23) package | Larger footprint and 2× higher thermal resistance (250 K/W j-a) | Prefer when existing SOT-23 layout exists but lower efficiency is acceptable |
| SS14-AU | Lower VR (40 V max), identical VF range, but not AEC-Q101 qualified; SMA package | Not suitable for automotive environments requiring stress qualification | Select only for cost-sensitive consumer-grade 5 V adapters or non-automotive SMPS |
Compared with RB050M-40TF and SS14-AU, PMEG4010CEJ-QX delivers superior thermal performance in ultra-compact packaging and guaranteed automotive reliability-making it optimal for space-constrained, mission-critical 12 V/24 V systems where conduction loss and qualification compliance are non-negotiable.

FAQ
What is the maximum continuous forward current for PMEG4010CEJ-QX at 85 °C ambient?
The datasheet specifies IF ≤ 1 A at Tsp ≤ 55 °C. At 85 °C ambient, derating applies: based on thermal resistance (150 K/W j-sp) and 150 °C max Tj, sustained current drops to approximately 0.65 A to maintain safe junction temperature. This value is derived from Ptot = (Tj − Tamb)/Rth(j-sp) and VF-based loss calculation.
Does PMEG4010CEJ-QX support reflow soldering per JEDEC J-STD-020?
Yes-the SOD323F package is qualified for lead-free reflow per JEDEC J-STD-020D. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp rates within specified limits. The recommended footprint (Fig. 6) uses 0.5 mm × 0.6 mm solder lands and 0.6 mm solder resist openings to ensure reliable wetting and void control.
How does the guard ring improve reliability in automotive applications?
The integrated guard ring mitigates electric field crowding at the silicon edge, preventing premature avalanche breakdown during load-dump transients (ISO 7637-2 Pulse 5a). This extends operational life under repeated 120 V/100 ms surges and improves long-term stability in high-humidity under-hood environments.
Can PMEG4010CEJ-QX be used in parallel for higher current handling?
No-Schottky diodes exhibit negative temperature coefficient of VF, causing current hogging if paralleled without ballasting. The datasheet does not recommend parallel operation. For >1 A, select a single higher-rated device such as PMEG6010CEJ-Q (60 V, 1 A) or PMEG4020CPA (40 V, 2 A in SOD123W).
