Product details
Overview
PMEG3010BEA-QF from Nexperia is a 1 A, 30 V low-forward-voltage Schottky barrier rectifier in SOD323 (SC-76) package, featuring an integrated guard ring for stress protection and AEC-Q101 qualification. It delivers 450–560 mV forward voltage at 1 A and 40–150 µA reverse leakage at 30 V, enabling high-efficiency DC-to-DC conversion and automotive-grade voltage clamping.
For engineers reviewing the PMEG3010BEA-QF datasheet, PMEG3010BEA-QF pinout, PMEG3010BEA-QF application, or PMEG3010BEA-QF equivalent, this device supports low-power rectification, blocking diode functions, and protection circuits where compact size, thermal robustness, and automotive reliability are critical.
Technical Context
This MEGA Schottky rectifier uses planar technology with an integrated guard ring to enhance ESD and transient stress resilience-critical for automotive load-dump and hot-swap environments. Its low VF minimizes conduction loss in 3.3 V/5 V rail conditioning and battery-powered systems.
Thermal design is constrained by Rth(j-sp) = 210 K/W (FR4, single-sided copper) and Rth(j-a) = 450 K/W in free air. Junction temperature must be limited to 150 °C, with thermal runaway mitigation required due to significant reverse power losses at elevated VR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 450–560 mV @ IF = 1 A, pulsed - enables <150 mW conduction loss in 1 A DC paths |
| Reverse Voltage (VR) | 30 V max - suitable for 24 V automotive supply rails with margin against transients |
| Reverse Leakage (IR) | 40–150 µA @ VR = 30 V - low enough to avoid excessive standby power in always-on modules |
| Diode Capacitance (Cd) | 55–70 pF @ VR = 1 V, 1 MHz - supports fast switching in <10 MHz DC/DC controllers |
| Junction Temperature (Tj) | −65 to +150 °C - rated for under-hood automotive operation without derating below 125 °C |
| Thermal Resistance (Rth(j-sp)) | 210 K/W - requires ≥1 cm² cathode pad on FR4 for sustained 1 A operation |
Pinout & Package
Encapsulated in SOD323 (SC-76), a 1.7 mm × 1.25 mm × 0.95 mm surface-mount plastic package with 1.3 mm lead pitch and cathode-marked top-side bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output node for forward conduction; connects to PCB thermal pad for heat dissipation |
| 2 | Anode (A) | Input node; polarity-sensitive connection to source or switch node in buck/flyback topologies |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Improves ruggedness against ESD and voltage transients per AEC-Q101 stress tests |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics |
| Low VF across current range | 215–250 mV @ 10 mA enables efficient biasing of low-current sensors and logic |
| SOD323 footprint compatibility | Standardized 1.3 mm pitch allows drop-in replacement in space-constrained layouts |
Applications
| Automotive Body Control Module | USB-C Power Delivery Clamp |
|---|---|
|
Use Scenario: Reverse-polarity protection and load-dump clamping in BCM power inputs. IC Role / Device Role / Timing Role: Schottky clamp diode placed between battery rail and LDO input. Use Value: 30 V VR rating withstands ISO 7637-2 pulse 5a; 450 mV VF limits voltage drop to <0.5 V at 1 A. |
Use Scenario: Output voltage clamping in USB-C PD sink designs with 20 V max input. IC Role / Device Role / Timing Role: Fast-response clamp limiting transient overshoot on VBUS line. Use Value: 70 pF capacitance avoids signal integrity degradation; 150 µA IR ensures minimal quiescent drain. |
| Industrial Sensor Node | Portable Medical Monitor |
|
Use Scenario: Low-loss blocking diode in energy-harvesting power path from solar cell or piezoelectric source. IC Role / Device Role / Timing Role: Prevents backfeed during low-light or idle conditions. Use Value: 285–340 mV VF @ 100 mA maximizes harvested energy transfer efficiency above 0.8 V threshold. |
Use Scenario: Battery backup isolation in dual-supply medical monitors with Li-ion primary and coin-cell backup. IC Role / Device Role / Timing Role: Prevents coin-cell discharge into main battery circuit during charging. Use Value: 40 µA typical IR at 3 V ensures >10-year backup runtime; SOD323 fits 3.5 mm height constraint. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TR | Higher VF (550–700 mV @ 1 A); same VR (30 V); SOD-123 package | Larger footprint (2.5 × 1.3 mm vs. 1.7 × 1.25 mm); lower thermal performance (Rth(j-sp) ≈ 300 K/W) | Select when legacy board layout prohibits SOD323 rework but AEC-Q101 is not required |
| SB130-E3/54 | Higher IF (3 A); higher VF (500–750 mV @ 1 A); DO-214AA package | Through-hole mounting; unsuitable for ultra-compact or automated SMT lines | Choose only for prototyping or high-reliability through-hole assemblies where thermal mass outweighs size penalty |
Compared with RB050M-30TR and SB130-E3/54, PMEG3010BEA-QF offers superior space efficiency, lower conduction loss, and automotive qualification-making it optimal for production-grade SMT designs requiring AEC compliance and sub-1 mm height.

FAQ
Is PMEG3010BEA-QF suitable for 24 V automotive systems?
Yes. With a 30 V reverse voltage rating and AEC-Q101 qualification, it withstands ISO 7637-2 load-dump pulses up to 35 V and operates reliably from −40 °C to +125 °C ambient. Its guard ring structure enhances immunity to electrical stress in vehicle power networks.
What is the maximum continuous forward current at 85 °C ambient?
At Tamb = 85 °C on standard FR4 (single-sided copper), the maximum continuous forward current is derated to approximately 0.7 A, based on thermal resistance Rth(j-sp) = 210 K/W and Tj(max) = 150 °C. Full 1 A operation requires Tamb ≤ 55 °C or enhanced PCB copper area.
Does PMEG3010BEA-QF have a cathode marking, and how is it identified?
Yes. The cathode is marked by a bar on the top surface of the SOD323 package, aligned with Pin 1. This matches the pinning diagram in the datasheet and corresponds to the "K" terminal in schematic symbols. The marking code "V2" appears adjacent to the bar.
Can PMEG3010BEA-QF replace older Schottky diodes like BAT54 in SOD-323 footprint?
No. While both use SOD323, BAT54 is a dual-series diode (two anodes, one common cathode) with 30 V VR but higher VF (≈800 mV @ 100 mA) and no AEC-Q101 qualification. PMEG3010BEA-QF is a single-diode rectifier optimized for 1 A continuous operation-not functionally interchangeable without circuit redesign.
