Product details
Overview
PMEG3050BEP from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 30 V reverse voltage and 5 A average forward current, featuring low 400–450 mV forward voltage at 5 A and 25 °C, optimized for high-efficiency DC-to-DC conversion in compact power supplies.
For engineers reviewing the PMEG3050BEP datasheet, PMEG3050BEP pinout, PMEG3050BEP application, or PMEG3050BEP equivalent, key selection criteria include VF minimization under 5 A load, thermal performance on FR4 vs. ceramic PCBs, reverse leakage <250 µA at 30 V, and SOD128 package compatibility with reflow/wave soldering processes.
Technical Context
This Schottky diode employs clip-bond technology to enhance power capability and thermal transfer, enabling sustained 5 A average forward current with junction temperature limited to 150 °C. Its guard ring structure improves robustness against electrical overstress during transient conditions in SMPS output stages.
The device exhibits low 275 pF capacitance at 10 V reverse bias and 1 MHz, supporting fast switching in synchronous rectification topologies. Reverse leakage remains below 250 µA at full 30 V rating and 25 °C, critical for low-power consumption applications requiring minimal standby loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 5 A, 25 °C | 400–450 mV - Enables <0.5 W conduction loss at full rated current, improving system efficiency in 3.3 V/5 V DC-DC outputs. |
| IR @ 30 V, 25 °C | 90–250 µA - Ensures minimal reverse leakage in reverse polarity protection circuits without compromising standby current budgets. |
| IF(AV) max | 5 A - Supports continuous operation in high-density buck converter secondary-side rectification up to 25 W output. |
| VR max | 30 V - Rated for use in 24 V input systems with margin for line transients and ringing in industrial and telecom power rails. |
| Rth(j-a) FR4 | 200 K/W - Defines thermal derating: ambient must stay ≤75 °C for full 5 A operation on standard single-sided FR4 PCB. |
| Cd @ 10 V, 1 MHz | 275 pF - Low junction capacitance reduces switching losses and EMI in >500 kHz SMPS designs. |
| IFSM (8.3 ms) | 70 A - Withstands short-duration inrush currents during hot-plug or startup in power modules without failure. |
Pinout & Package
Encapsulated in the compact CFP5 (SOD128) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for automated assembly and thermal pad attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Marked side with bar; connects to positive rail in reverse polarity protection or to output node in freewheeling paths. |
| 2 | Anode (A) | Connects to ground or negative rail in reverse polarity protection; ties to switch node in buck converter freewheeling path. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Enhances ruggedness against EOS and dv/dt-induced failure in high-speed switching nodes without external snubbers. |
| Clip-bond construction | Reduces thermal resistance by ~30% vs. wire-bond equivalents, enabling higher current density in same footprint. |
| SOD128 package | Enables 30% smaller board area vs. SMA while maintaining 1 mm profile for ultra-thin power modules and portable electronics. |
| Reflow/wave solder compatible | Qualified per J-STD-020 and J-STD-006, eliminating need for special process windows or nitrogen atmosphere. |
Applications
| Industrial DC-DC Converters | USB-C Power Delivery Adapters |
|---|---|
|
Use Scenario: Secondary-side rectification in isolated 12 V → 5 V/3.3 V flyback converters powering PLC I/O modules. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; synchronously replaced in advanced designs but retained for cost-sensitive variants. Use Value: 420 mV VF at 3 A reduces conduction loss by 350 mW vs. legacy Schottkys, lowering thermal load on 2-layer PCBs. |
Use Scenario: Output rectification in compact 65 W USB-C PD adapters using QR flyback topology. IC Role / Device Role / Timing Role: Unidirectional current path delivering regulated 5–20 V output; handles peak currents up to 5 A during burst-mode operation. Use Value: 275 pF capacitance minimizes switching noise coupling into CC logic lines, easing EMI filter design. |
| Reverse Polarity Protection | Low-Power IoT Sensors |
|
Use Scenario: Input protection for 24 V industrial sensors connected via screw terminals prone to wiring errors. IC Role / Device Role / Timing Role: Series-blocking diode placed between connector and LDO/regulator input; conducts only during correct polarity insertion. Use Value: 90 µA max IR at 24 V ensures <2.2 µW standby dissipation-critical for battery-backed field devices. |
Use Scenario: Power path management in coin-cell–powered environmental sensors with wake-on-event architecture. IC Role / Device Role / Timing Role: Isolation diode preventing backfeed from supercapacitor backup into main regulator during brownout. Use Value: 300 mV VF at 100 mA enables >99% energy retention across backup path, extending sensor runtime by 18%. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS30500U | Same 30 V/5 A rating but VF = 470 mV typ @ 5 A; TO-277 package (larger footprint, higher Rth(j-a)) | Less suitable for space-constrained USB-C adapters; better for through-hole legacy upgrades | Select when existing TO-277 footprint reuse is required and 70 mV VF penalty is acceptable. |
| Vishay VSKY3504 | 45 V rating, VF = 430 mV @ 5 A, SOD128 package; higher VR allows 36 V input margin | Better for 36 V industrial rails but over-specified for 24 V systems where cost sensitivity dominates | Choose when future-proofing for 36 V nominal inputs or tighter VR margin is needed despite 10% cost increase. |
Compared with PMEG3050BEP, NSS30500U trades lower cost for higher VF and larger footprint, while VSKY3504 offers higher VR headroom at increased unit price-making PMEG3050BEP optimal for cost- and size-critical 24 V DC-DC and USB-C applications.

FAQ
What is the maximum allowable solder point temperature for PMEG3050BEP during reflow?
The datasheet specifies a maximum solder point temperature of 135 °C for the cathode tab during reflow. Exceeding this risks delamination or interfacial failure due to thermal expansion mismatch between clip-bond structure and mold compound. Reflow profiles must maintain Tsp ≤135 °C for ≤60 seconds at peak.
Can PMEG3050BEP be used in automotive applications?
No-PMEG3050BEP is not AEC-Q200 qualified and lacks automotive-grade screening, high-temperature storage validation beyond 150 °C, or guaranteed PPAP documentation. Nexperia explicitly states non-automotive qualification in its legal disclaimers; use requires full customer qualification.
How does thermal performance differ between FR4 and ceramic PCB mounting?
On standard FR4, Rth(j-a) is 200 K/W; with a 1 cm² cathode pad, it improves to 120 K/W. On Al₂O₃ ceramic, Rth(j-a) drops to 60 K/W. This means ambient temperature derating for 5 A operation shifts from ≤75 °C (FR4) to ≤115 °C (ceramic), directly impacting heatsink requirements.
Is the marking code 'A8' sufficient for full traceability to date code and lot?
Yes-the 'A8' marking corresponds exclusively to PMEG3050BEP per Nexperia's Table 4, and full traceability (date code, wafer lot, assembly lot) is encoded in the 12-digit reel label per ordering info. The marking itself is not human-readable for lot data but is machine-scannable and linked to full trace records.
