Product details
Overview
PMEG4030ETP from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for high-temperature operation up to 175 °C, 40 V reverse voltage rating, 3 A average forward current, and low 430–490 mV forward voltage at 3 A/25 °C - used in DC-to-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG4030ETP datasheet, PMEG4030ETP pinout, PMEG4030ETP application, or PMEG4030ETP equivalent, this device is selected for low-VF, high-temperature rectification where thermal robustness and solder compatibility (reflow/wave) are critical in compact SMD power designs.
Technical Context
This Schottky diode employs clip-bonding technology to enhance thermal performance and power capability, enabling stable operation at junction temperatures up to 175 °C. Its guard ring structure improves reliability under electrical stress and transient conditions.
The SOD128 (CFP5) package delivers low thermal resistance - as low as 12 K/W from junction to solder point - and supports both reflow and wave soldering. Diode capacitance is 140 pF at 10 V, supporting high-frequency switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum blocking capability without breakdown in standard operating conditions |
| Average Forward Current (IF(AV)) | 3 A - continuous DC or pulsed current handling at Tsp ≤ 165 °C on standard FR4 PCB |
| Forward Voltage (VF) | 430–490 mV at IF = 3 A, Tj = 25 °C - enables high-efficiency rectification with minimal conduction loss |
| Reverse Current (IR) | 35–200 µA at VR = 40 V, Tj = 25 °C - low leakage preserves efficiency in standby and light-load modes |
| Junction Temperature (Tj) | 175 °C - allows operation in under-hood, industrial, or enclosed high-ambient environments |
| Thermal Resistance (Rth(j-sp)) | 12 K/W - low junction-to-solder-point resistance enables effective heat transfer via cathode tab |
Pinout & Package
Encapsulated in a compact, flat-lead SOD128 (CFP5) surface-mount plastic package measuring 3.8 mm × 2.6 mm × 1.0 mm, with 4 mm pitch and optimized thermal pad layout for cathode-side heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; marked by bar on top surface; primary heat path to PCB via large copper pad |
| 2 | Anode (A) | Positive input terminal; connects to source side of rectification path; lower thermal mass than cathode |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ruggedness against ESD and voltage transients without derating VR |
| Clip-bonding construction | Reduces bond wire inductance and increases current-carrying cross-section versus wire-bonded equivalents |
| Soldering compatibility | Qualified for both lead-free reflow (peak 260 °C) and wave soldering per J-STD-020/001 |
| High-temperature rating | Rated for continuous operation at Tj = 175 °C - exceeds standard Schottky limits by ≥25 °C |
| Low-profile SMD package | SOD128 footprint enables dense board layouts while maintaining >1 mm creepage/clearance at 40 V |
Applications
| DC-DC Converter Output Rectification | Reverse Polarity Protection |
|---|---|
Use Scenario: Secondary-side rectification in isolated or non-isolated buck-derived DC-DC converters delivering 3.3 V–12 V at up to 3 A. IC Role / Device Role / Timing Role: Unidirectional current valve replacing synchronous MOSFETs where gate drive complexity must be avoided. Use Value: 430 mV VF reduces conduction loss by ~30% vs. standard 600 mV Schottkys, improving efficiency at light-to-moderate loads. |
Use Scenario: Input protection for USB-powered peripherals, battery-backed sensors, and field-deployable IoT nodes. IC Role / Device Role / Timing Role: Series-blocking diode placed between power input and system rail to prevent damage during incorrect connector insertion. Use Value: Low 35 µA IR at 25 °C minimizes standby current drain, extending battery life in always-on devices. |
| High-Temperature Power Supply | Low-Voltage AC/DC Adapter |
Use Scenario: Auxiliary power supply in automotive engine control units (ECUs), industrial motor drives, and LED drivers exposed to ambient >105 °C. IC Role / Device Role / Timing Role: Input rectifier in flyback or forward converter front-end operating continuously at Tamb ≥ 100 °C. Use Value: 175 °C Tj rating eliminates need for oversized heatsinking or derating in thermally constrained enclosures. |
Use Scenario: Output rectification in compact wall adapters supplying 5 V/2.4 A for consumer electronics. IC Role / Device Role / Timing Role: Low-loss freewheeling path in discontinuous conduction mode (DCM) flyback secondary stage. Use Value: SOD128 package fits tight 12 mm × 12 mm board area budgets while sustaining 3 A peak currents without thermal shutdown. |
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-3EYH02-M3/54 | Same 40 V/3 A rating but higher VF (520 mV typ.), no guard ring, TO-277 package (larger, higher Rth(j-a)) | Limited to ≤150 °C Tj; less robust in surge-prone inputs | Select when legacy TO-277 footprint is required and thermal margin >25 K exists |
| ON Semiconductor NSR3403MX | Lower VF (390 mV typ.) but rated only to 150 °C Tj; same SOD128 package | Not suitable for sustained >150 °C ambient or junction-limited designs | Select only for cost-sensitive, lower-temperature applications where 25 °C Tj margin is acceptable |
Compared with VS-3EYH02-M3/54 and NSR3403MX, PMEG4030ETP uniquely combines 175 °C operation, guard ring protection, and sub-490 mV VF in SOD128 - making it optimal for thermally aggressive, reliability-critical rectification where both efficiency and ruggedness are mandatory.

FAQ
What is the maximum allowable soldering temperature for PMEG4030ETP?
The PMEG4030ETP is qualified for lead-free reflow soldering with a peak temperature of 260 °C for ≤30 seconds, per J-STD-020. Wave soldering is also supported with preheat ≤150 °C and contact time ≤5 seconds. Exceeding these limits risks delamination or parametric shift.
Can PMEG4030ETP replace a standard 1N5822 in existing designs?
No - the 1N5822 uses DO-201AD packaging (through-hole, higher Rth(j-a) ≈ 50 K/W) and is rated only to 125 °C. PMEG4030ETP is SMD-only, has 175 °C Tj, and requires PCB layout adaptation for its SOD128 footprint and cathode thermal pad.
How does the guard ring improve reliability in PMEG4030ETP?
The integrated guard ring mitigates edge breakdown under high dv/dt or reverse-biased transients by redistributing electric field concentration away from the active junction periphery - verified by accelerated life testing showing >2× improvement in surge survivability versus non-guarded equivalents at 40 V.
Is PMEG4030ETP suitable for automotive under-hood applications?
While rated to 175 °C Tj, PMEG4030ETP is not AEC-Q101 qualified. It may be used in non-safety-critical under-hood functions (e.g., cabin HVAC control, lighting modules) only after full system-level validation - Nexperia does not warrant automotive use without explicit qualification.
