Product details
Overview
PMEG4010BEA from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 40 V reverse voltage and 1 A forward current, featuring a very low 540–640 mV forward voltage at 1 A and 25 °C. It is used in low-voltage DC-to-DC conversion stages, reverse polarity protection circuits, and blocking diode applications where minimal conduction loss and compact size are critical.
For engineers reviewing the PMEG4010BEA datasheet, PMEG4010BEA pinout, PMEG4010BEA application, or PMEG4010BEA equivalent, key selection criteria include verified low VF performance at full rated current, thermal resistance to solder point (90 K/W), SOD323 package footprint compatibility, and reverse leakage stability under pulsed 40 V stress.
Technical Context
This Schottky rectifier employs a planar die structure with an integrated guard ring to enhance ruggedness against transient overvoltage and electrostatic stress. Its low barrier height enables sub-640 mV forward drop at 1 A while maintaining 30–100 µA reverse leakage at 40 V and 25 °C under pulsed conditions.
The device is optimized for surface-mount operation on FR4 PCBs with single-sided copper, delivering 210 K/W junction-to-solder-point thermal resistance when mounted with a 1 cm² cathode pad. It supports repetitive peak forward currents up to 3.5 A (1 ms, 50% duty) and non-repetitive surges of 10 A (8 ms square wave).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum continuous blocking capability; defines safe operating range in clamping and reverse-battery protection. |
| Forward Current (IF) | 1 A - Continuous DC current rating at ≤55 °C solder point temperature; sets usable load capacity in power paths. |
| Forward Voltage (VF) | 540–640 mV @ 1 A, 25 °C - Directly determines conduction loss (0.54–0.64 W at 1 A); enables high-efficiency low-voltage rectification. |
| Reverse Current (IR) | 30–100 µA @ 40 V, pulsed - Low leakage preserves efficiency in standby and low-power modes; validated under IEC-standard pulse conditions. |
| Diode Capacitance (Cd) | 43–50 pF @ 1 V, 1 MHz - Enables fast switching in DC-DC feedback paths and high-frequency clamp circuits without excessive ringing. |
| Junction Temperature (Tj) | 150 °C - Maximum allowable die temperature; constrains thermal design margin when operating near IF max under ambient stress. |
| Thermal Resistance (Rth(j-sp)) | 90 K/W - Quantifies heat transfer efficiency from junction to cathode solder point; critical for estimating temperature rise in layout-constrained designs. |
Pinout & Package
Encapsulated in the ultra-compact SOD323 (SC-76) plastic SMD package (1.7 mm × 1.25 mm × 0.95 mm), the PMEG4010BEA uses a two-terminal configuration optimized for high-density board layouts and automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output/low-side terminal; connects to ground or return path; carries full forward current and anchors thermal dissipation via solder pad. |
| 2 | Anode (A) | Input/high-side terminal; receives input voltage or switched node; polarity-sensitive connection for unidirectional conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Enhances ESD and transient voltage immunity without external components; improves reliability in noisy industrial and automotive-adjacent environments. |
| Very low VF at 1 A | Reduces conduction loss by ≥30% vs. comparable 40 V Schottkys; directly increases efficiency in 3.3 V/5 V DC-DC output stages. |
| SOD323 package footprint | Enables placement in space-constrained locations (e.g., wearables, IoT sensors); compatible with standard 0603-class pick-and-place and reflow profiles. |
| Pulsed reverse current rating | Validated at 30–100 µA under 40 V, 300 µs pulses - ensures stable clamping behavior during fast transients in protection circuits. |
Applications
| USB Power Delivery Protection | Low-Voltage DC-DC Output Rectification |
|---|---|
Use Scenario: Preventing reverse current flow and voltage backfeed between dual USB-C ports sharing a common bus. IC Role / Device Role / Timing Role: Blocking diode placed in series with each port's VBUS line to enforce unidirectional power routing. Use Value: Sub-640 mV VF minimizes voltage drop and power loss at 1 A, preserving PD negotiation margins and reducing thermal load on connectors. |
Use Scenario: Rectifying synchronous buck converter output in battery-powered microcontroller systems operating at 1.8–3.3 V. IC Role / Device Role / Timing Role: Low-loss freewheeling path during high-side switch off-time in non-synchronous configurations. Use Value: 43–50 pF capacitance and fast recovery enable clean switching transitions without excessive ringing or EMI in 1–3 MHz converters. |
| Reverse Polarity Input Protection | Low-Power Sensor Node Clamping |
Use Scenario: Safeguarding 24 V industrial sensor inputs against accidental reverse wiring during field installation. IC Role / Device Role / Timing Role: Series-connected Schottky in the positive rail to block reverse current while passing normal forward current. Use Value: 40 V VR rating provides 16 V headroom above nominal 24 V supply; guard ring withstands installation-induced transients. |
Use Scenario: Clamping analog front-end inputs of environmental sensors exposed to ESD events in unshielded enclosures. IC Role / Device Role / Timing Role: Low-capacitance shunt diode tied between signal line and ground to divert ESD pulses. Use Value: 43–50 pF Cd avoids signal distortion in <100 kHz sensor bandwidths; low VF ensures minimal offset in precision measurement paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-40T1G (ON Semiconductor) | Same 40 V VR, 1 A IF, but VF = 550–750 mV @ 1 A; SOD-523 package (smaller, 1.2 × 0.8 mm). | Higher VF increases conduction loss by ~0.1 W at 1 A; smaller footprint limits thermal mass and solder-pad area. | Select when board area is more constrained than thermal budget; verify Rth(j-sp) compatibility with layout. |
| SS14 (Good-Ark) | 40 V VR, 1 A IF, VF = 500–600 mV @ 1 A; DO-214AC (SMA) package (larger, 4.3 × 2.6 mm). | Lower typical VF improves efficiency slightly, but SMA package occupies >5× board area and requires different reflow profile. | Select when higher surge current (30 A IFSM) or legacy through-hole compatibility is required; not suitable for ultra-dense layouts. |
Compared with RB520S-40T1G and SS14, the PMEG4010BEA delivers the best balance of low VF, proven SOD323 thermal performance (90 K/W Rth(j-sp)), and robust guard-ring protection-making it optimal for space-limited, thermally sensitive 1 A power rails.

FAQ
What is the maximum continuous forward current for PMEG4010BEA under real-world PCB conditions?
The PMEG4010BEA is rated for 1 A continuous forward current when the solder point temperature (Tsp) does not exceed 55 °C. This assumes mounting on an FR4 PCB with single-sided copper, tin-plated traces, and the standard SOD323 footprint per Nexperia's datasheet Figure 5. Exceeding this Tsp limit risks accelerated degradation and thermal runaway due to Schottky's negative temperature coefficient.
Does PMEG4010BEA have automotive qualification?
No. The January 2023 datasheet explicitly states that PMEG4010BEA was changed to non-automotive qualification in revision v.4. It is not tested or certified to AEC-Q101 or other automotive standards. For automotive applications, Nexperia offers separate -Q qualified variants-consult their website for PMEG4010BEA-Q or equivalent qualified Schottky rectifiers.
How does the integrated guard ring improve reliability in protection circuits?
The guard ring mitigates edge breakdown under high electric field stress, significantly improving resistance to ESD (per IEC 61000-4-2) and transient overvoltage events. In reverse-polarity or clamping applications, it prevents localized avalanche at the die periphery-extending operational life and maintaining consistent IR and VF parameters after repeated stress exposure.
Can PMEG4010BEA be used in synchronous rectification topologies?
No. As a passive Schottky rectifier, PMEG4010BEA lacks gate control and cannot replace actively driven MOSFETs in synchronous rectification. It is designed for non-synchronous freewheeling or simple blocking roles. Using it in place of a controlled switch would result in unregulated conduction, increased losses, and potential instability in current-mode-controlled converters.
