Product details
Overview
PMEG4050ETP from Nexperia is a high-temperature planar Schottky barrier rectifier in SOD128 (CFP5) package, designed for low-VF power conversion with 40 V reverse voltage rating, 5 A average forward current, and 175 °C maximum junction temperature. It integrates a guard ring for stress protection and uses clip-bonding technology to deliver high power capability in compact surface-mount form - deployed in DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG4050ETP datasheet, PMEG4050ETP pinout, PMEG4050ETP application, or PMEG4050ETP equivalent, this device is selected for high-efficiency, high-temperature rectification where low forward voltage drop (430–490 mV @ 5 A, 25 °C), low reverse leakage (≤300 µA @ 40 V, 25 °C), and thermal robustness (Tj ≤ 175 °C) are critical.
Technical Context
This Schottky diode employs a planar silicon structure with integrated guard ring to suppress edge breakdown and improve reliability under repetitive surge and thermal stress. Its clip-bonded construction reduces thermal resistance and enhances current handling beyond conventional wire-bonded equivalents.
It operates as a unidirectional, two-terminal power rectifier with cathode-anode polarity defined by a marking bar on the SOD128 body. The device exhibits low capacitance (220 pF @ 10 V, 1 MHz) and stable forward voltage across temperature (340–390 mV @ 5 A, 125 °C), enabling efficient switching in high-frequency SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum blocking voltage before significant reverse conduction; defines usable input range in buck/boost converters. |
| Average Forward Current (IF(AV)) | 5 A - Continuous DC or pulsed current capability at Tsp ≤ 155 °C; supports high-power density board layouts. |
| Forward Voltage (VF) | 430–490 mV @ 5 A, 25 °C - Low conduction loss improves system efficiency; enables >95% efficiency in 5–12 V output DC-DC stages. |
| Reverse Current (IR) | 60–300 µA @ 40 V, 25 °C - Low leakage preserves standby power budget in battery-powered systems. |
| Junction Temperature (Tj) | 175 °C - Enables operation in under-hood automotive auxiliary modules, industrial motor drives, and sealed power supplies without derating. |
| Thermal Resistance (Rth(j-sp)) | 12 K/W - Low junction-to-solder-point resistance allows effective heat transfer via cathode tab to PCB copper pour. |
| Diode Capacitance (Cd) | 220 pF @ 10 V - Minimizes switching node ringing and EMI in >100 kHz SMPS designs. |
Pinout & Package
Encapsulated in the SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for reflow and wave soldering. Cathode marked by a bar on the component top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main current exit terminal; connected to PCB ground plane or low-side return path; large copper pad required for thermal management. |
| 2 | Anode (A) | Main current entry terminal; ties to switch node or input rail; minimal trace inductance critical for high-frequency performance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge electric field concentration, improving long-term reliability under repeated reverse-bias stress and temperature cycling. |
| Clip-bonding technology | Reduces bond wire inductance and thermal resistance versus wire-bonded Schottkys, supporting higher peak currents (IFSM = 70 A) and lower VF drift. |
| SOD128 package footprint | Enables high-density layout with 2.6 mm width - 30% smaller than SMA while maintaining 5 A rating and superior thermal performance. |
| Reflow/wave solder compatible | Qualified per J-STD-020 and J-STD-006; withstands peak reflow temperatures up to 260 °C, eliminating assembly process restrictions. |
Applications
| High-Efficiency DC-DC Conversion | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Secondary-side synchronous rectification in isolated 12 V → 3.3 V/5 V flyback or forward converters. IC Role / Device Role / Timing Role: Uncontrolled low-loss rectifier replacing MOSFETs in cost-sensitive designs; conducts during transformer secondary voltage positive half-cycle. Use Value: 430 mV VF cuts conduction loss by ~40% vs. standard silicon diodes, directly increasing converter efficiency from 88% to 92% at full load. |
Use Scenario: Input protection for USB-C PD adapters, PoE injectors, and industrial 24 V DC power inputs. IC Role / Device Role / Timing Role: Series-connected anode-to-input, cathode-to-load; blocks reverse voltage during plug-in misorientation or supply reversal. Use Value: Withstands 40 V reverse bias and 175 °C ambient - ensures fail-safe operation in hot enclosures without thermal shutdown. |
| Low-Voltage Rectification | High-Temperature Power Supplies |
|
Use Scenario: Output rectification in 3.3 V/5 V non-isolated buck converters powering FPGAs, ASICs, or microcontrollers. IC Role / Device Role / Timing Role: Freewheeling diode in asynchronous buck topology; clamps inductor current during high-side switch off-time. Use Value: Low 220 pF capacitance minimizes switching node oscillation, reducing EMI filter burden and enabling smaller output capacitors. |
Use Scenario: Auxiliary power supply in motor drive inverters, HVAC control boards, and railway signaling units operating at 105–150 °C ambient. IC Role / Device Role / Timing Role: Primary rectifier in offline AC-DC stage or DC input stage; handles continuous 5 A load at elevated board temperature. Use Value: Rated for Tj = 175 °C with Rth(j-sp) = 12 K/W - maintains 5 A rating at 125 °C ambient when mounted on 1 cm² cathode pad. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-50WQ04FNTR-M3 | Same 40 V/5 A rating but TO-277 package (larger footprint, higher Rth(j-a) = 45 K/W); VF = 450 mV typ. | Requires more PCB area and heatsinking; less suitable for ultra-thin or high-density designs. | Select when legacy TO-277 footprint compatibility is required or when higher surge current (IFSM = 120 A) is prioritized over size. |
| ON Semiconductor MBR540LSFT1G | SOD-123FL package (smaller, 2.7 × 1.7 mm); lower IF(AV) = 3 A; VF = 520 mV @ 3 A. | Limited to ≤3 A loads; higher VF increases conduction loss by ~21% at rated current. | Choose only for space-constrained <3 A applications where SOD-123FL footprint is mandated and thermal margin is ample. |
Compared with VS-50WQ04FNTR-M3 and MBR540LSFT1G, PMEG4050ETP delivers optimal balance of miniaturization (SOD128), thermal performance (12 K/W Rth(j-sp)), and efficiency (430 mV VF), making it preferred for next-gen high-density, high-temperature power supplies.

FAQ
What is the maximum allowable soldering temperature for PMEG4050ETP?
The PMEG4050ETP is qualified for standard lead-free reflow soldering per J-STD-020, with a peak temperature of 260 °C for ≤30 seconds. Wave soldering is also supported using the recommended footprint in Figure 16, with preheat ≤150 °C and contact time ≤5 seconds. Exceeding these limits risks delamination or internal bond damage.
Can PMEG4050ETP replace a standard silicon rectifier in an existing 24 V input supply?
Yes - provided the original rectifier's reverse voltage rating is ≤40 V and average current ≤5 A. PMEG4050ETP's lower VF reduces conduction losses and thermal rise, but its higher reverse leakage (vs. silicon) must be verified against the design's standby current budget. No circuit changes are needed for pin-compatible replacement in SOD128 footprints.
How does the guard ring affect reliability in high-humidity environments?
The integrated guard ring mitigates surface leakage paths and prevents premature edge breakdown under high humidity and bias stress. Accelerated testing per JEDEC JESD22-A110 shows no parameter shift after 1000 hours at 85 °C/85% RH, confirming enhanced moisture resistance versus non-guard-ring Schottky diodes in conformally coated industrial modules.
Is PMEG4050ETP automotive-qualified?
No - the datasheet revision history explicitly states this part was changed to non-automotive qualification in v.3 (2023). It lacks AEC-Q101 stress testing and automotive-grade traceability. For automotive use, Nexperia offers the PMEG4050ETP-Q variant, which shares identical electrical specs but includes extended qualification and PPAP documentation.
