Product details
Overview
PMEG4010BEA-QF from Nexperia is a 1 A, 40 V planar MEGA Schottky barrier rectifier in SOD323 (SC-76) package, featuring very low forward voltage (540–640 mV at 1 A), integrated guard ring for stress protection, and AEC-Q101 qualification for automotive use - deployed in DC-DC converter output stages and reverse polarity protection circuits.
For engineers reviewing the PMEG4010BEA-QF datasheet, PMEG4010BEA-QF pinout, PMEG4010BEA-QF application, or PMEG4010BEA-QF equivalent, key selection criteria include forward voltage at 1 A, thermal resistance to solder point (90 K/W), reverse leakage at 40 V (≤100 µA), diode capacitance (43–50 pF), and AEC-Q101 qualification status.
Technical Context
This Schottky rectifier uses a planar MEGA structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF enables high-efficiency operation in low-voltage, high-current paths where conduction loss dominates.
The device operates with junction temperature up to 150 °C and is characterized for FR4 PCB mounting with single-sided copper. Thermal resistance from junction to solder point is 90 K/W - critical for thermal design in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward current (IF) | 1 A continuous - supports compact 12 V/5 V DC-DC output rectification without forced cooling |
| Reverse voltage (VR) | 40 V - suitable for 24 V automotive systems with margin against load dump transients |
| Forward voltage (VF) | 540–640 mV at 1 A, 25 °C - reduces power loss to ≤640 mW versus >1.2 V for standard silicon diodes |
| Reverse leakage (IR) | ≤100 µA at 40 V, 25 °C - ensures minimal standby power drain in battery-sensitive applications |
| Diode capacitance (Cd) | 43–50 pF at 1 V, 1 MHz - enables fast switching in <1 MHz buck converters without excessive ringing |
| Thermal resistance (Rth(j-sp)) | 90 K/W - allows direct thermal coupling to PCB copper pour for passive heat dissipation |
| Junction temperature (Tj) | 150 °C max - supports operation in under-hood environments with ambient up to 125 °C |
Pinout & Package
Encapsulated in SOD323 (SC-76) surface-mount plastic package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode marked with bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output node for rectified current; connects to PCB copper pour for thermal relief and EMI control |
| 2 | Anode (A) | Input node for unidirectional current flow; requires low-inductance trace routing in high-dI/dt paths |
Key Features
| Feature | Design Value |
|---|---|
| Very low VF Schottky architecture | 640 mV max at 1 A enables ≥92% efficiency in 5 V synchronous-buck secondary-side rectification |
| Integrated guard ring | Suppresses edge avalanche during voltage transients - improves robustness in automotive load-dump conditions |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, HAST, and ESD (HBM ≥2 kV) |
| SOD323 footprint | 0.95 mm height and 1.7 mm length enable placement in ultra-thin modules (e.g., ADAS camera ECUs) |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Clamp |
|---|---|
Use Scenario: Reverse polarity protection on 12 V supply rail feeding microcontroller and CAN transceiver. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage during battery misconnection.

| Industrial 24 V IoT Gateway | Low-Power Wearable Charger |
Use Scenario: OR-ing diode in dual 24 V input redundancy path for PoE-powered gateway. IC Role / Device Role / Timing Role: Low-loss current steering element enabling seamless switchover. Use Value: 100 µA max IR at 40 V ensures <2.4 µW standby loss per diode in always-on mode. |
Use Scenario: Output rectifier in miniature 3.3 V buck-boost charger for Li-ion coin cell. IC Role / Device Role / Timing Role: High-efficiency synchronous rectifier replacement in discontinuous conduction mode. Use Value: 0.95 mm profile fits within 3.2 mm total board thickness constraint of wristband PCB. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB055LAM-40TR | Higher VF (700 mV typ. @ 1 A); same 40 V VR; SOD-123 package (larger footprint) | Less suitable for ultra-thin designs; higher conduction loss in thermally constrained layouts | Select when cost sensitivity outweighs VF and size requirements |
| SS14-E3/5AT | Lower VR (40 V same); VF 500 mV typ. @ 1 A; SMA package (3.5 mm × 1.6 mm) | Not AEC-Q101 qualified; lacks guard ring; unsuitable for automotive under-hood deployment | Select only for non-automotive consumer applications with relaxed reliability requirements |
Compared with RB055LAM-40TR and SS14-E3/5AT, PMEG4010BEA-QF delivers the lowest VF in smallest AEC-Q101-compliant package - making it optimal for space- and efficiency-critical automotive subsystems where thermal headroom is limited.

FAQ
What is the maximum allowable soldering temperature for PMEG4010BEA-QF?
The device is qualified for reflow soldering per J-STD-020, with peak temperature of 260 °C for ≤30 seconds. The SOD323 package withstands this profile without delamination or parameter shift, provided solder paste volume and preheat ramp rates follow Nexperia's recommended footprint (Fig. 5).
Does PMEG4010BEA-QF support bidirectional current flow?
No - it is a unidirectional Schottky rectifier. Current flows only from anode to cathode; reverse conduction is blocked above 40 V. It cannot replace a bidirectional TVS or ESD diode, nor function as a synchronous rectifier switch without external gate control.
How does the guard ring affect layout requirements?
The integrated guard ring requires no special PCB layout but mandates minimum 0.2 mm clearance between cathode pad and adjacent traces to prevent field crowding. Standard SOD323 footprints (e.g., Fig. 5) already satisfy this requirement.
Is PMEG4010BEA-QF compatible with lead-free and RoHS-compliant assembly?
Yes - the device is fully RoHS-compliant and rated for lead-free reflow. Its termination is matte tin, and the SOD323 package meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), eliminating bake requirements before assembly.
