Product details
Overview
PMEG3020CEP from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection. It delivers 2 A average forward current at ≤30 V reverse voltage, with a typical forward voltage of 365 mV at 2 A and 25 °C, housed in a compact SOD128 (CFP5) surface-mount package.
For engineers reviewing the PMEG3020CEP datasheet, PMEG3020CEP pinout, PMEG3020CEP application, or PMEG3020CEP equivalent, key selection criteria include low VF performance under 2 A load, thermal resistance to solder point (12 K/W), clip-bond power capability, and compatibility with reflow/wave soldering on FR4 or ceramic PCBs.
Technical Context
This Schottky diode employs planar die construction with an integrated guard ring to enhance ruggedness against electrical overstress and improve reliability in transient-prone environments. Its clip-bond packaging enables higher power handling versus wire-bonded equivalents while maintaining low thermal resistance.
The device operates with minimal forward conduction loss-VF remains ≤420 mV at full 2 A load and 25 °C-and exhibits low reverse leakage (55 µA at 5 V, 25 °C), supporting high-efficiency topologies where reverse recovery loss must be eliminated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 2 A average forward current - supports continuous 2 A DC or pulsed loads with δ = 0.5 at Tsp ≤ 140 °C |
| VR | 30 V reverse voltage - suitable for 24 V rail protection and SMPS secondary-side rectification |
| VF @ 2 A | 365–420 mV - reduces conduction loss by ~40% vs. standard silicon diodes in low-VF critical paths |
| IR @ 5 V | 55 µA max - ensures minimal standby power drain in battery-backed or energy-sensitive systems |
| Rth(j-sp) | 12 K/W - enables efficient heat transfer from junction to cathode solder point on FR4 with 1 cm² pad |
| Cd @ 1 V | 170 pF - low capacitance preserves switching speed in high-frequency DC/DC converters (>1 MHz) |
| Tj(max) | 150 °C - allows operation in thermally constrained industrial or automotive-adjacent environments |
Pinout & Package
Encapsulated in the SOD128 (CFP5) plastic surface-mount package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for automated assembly and thermal relief.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Marked side (bar) - connects to output/load return; serves as primary thermal path via clip-bonded cathode tab |
| 2 | Anode (A) | Input/positive rail connection - low-inductance terminal for fast-switching node placement |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD and surge robustness without derating - validated per IEC 61000-4-2 Level 4 (8 kV contact) |
| Clip-bond interconnect | Enables 2.1 W total power dissipation on FR4 (standard footprint) - 2× higher than comparable wire-bond SOD128 diodes |
| Reflow/wave solder compatible | Qualified per J-STD-020D and IPC-J-STD-001 - no special profile needed for lead-free reflow (peak 260 °C) |
| Low thermal resistance to solder point | 12 K/W - allows direct thermal coupling to copper pour, reducing junction temperature rise by >30% vs. standard SOD128 |
| Marking code AG | Unambiguous identification on 2.6 mm width body - supports AOI verification and traceability in high-mix production |

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 NSS20201MR6T1G | Same SOD128 package, 20 V VR, 2 A IF(AV), VF = 390 mV @ 2 A - lower voltage rating limits use to ≤15 V systems | Restricted to 12 V rail protection; unsuitable for 24 V SMPS secondary rectification | Select only when VR ≤ 20 V suffices and legacy ON Semi sourcing is required |
| Vishay VS-2EDH02HM3/85A | SOD123 package (smaller), 30 V VR, 2 A IF(AV), VF = 450 mV @ 2 A - higher VF increases conduction loss by 100 mW at full load | Lacks clip-bond construction - Rth(j-sp) = 25 K/W vs. 12 K/W, limiting thermal headroom on FR4 | Acceptable for space-constrained designs where thermal margin >15 °C exists and 450 mV VF is tolerable |
Compared with NSS20201MR6T1G and VS-2EDH02HM3/85A, PMEG3020CEP uniquely combines 30 V rating, sub-400 mV VF, and 12 K/W thermal resistance in SOD128 - making it optimal for thermally dense 24 V DC/DC and reverse protection where efficiency and board area are co-constrained.

FAQ
What is the maximum allowable solder point temperature for PMEG3020CEP during reflow?
The device is qualified for lead-free reflow per J-STD-020D with peak temperature up to 260 °C. The absolute maximum solder point temperature is 260 °C for ≤30 seconds, verified using thermocouple attachment to the cathode tab per JEDEC standards. Exceeding this risks delamination of the clip-bond interface.
Can PMEG3020CEP replace a standard silicon diode in a 24 V SMPS secondary rectifier?
Yes - its 30 V VR rating and 2 A IF(AV) support direct substitution in 24 V-output flyback or forward converters. With VF ≈365 mV at 2 A, it reduces conduction loss by ~65% versus a 1N5822 (VF ≈1.0 V), improving efficiency by 1.2–1.8% at full load depending on duty cycle.
Does the guard ring affect the device's reverse recovery behavior?
No - as a Schottky diode, PMEG3020CEP has no minority-carrier storage and therefore zero reverse recovery time (trr). The guard ring solely improves ruggedness against dv/dt-induced snapback and ESD, not switching dynamics. Measured trr is undefined (non-applicable).
How does thermal performance differ between FR4 and ceramic PCB mounting?
On FR4 with 1 cm² cathode pad, Rth(j-sp) = 12 K/W; on Al₂O₃ ceramic, Rth(j-a) drops to 60 K/W (vs. 200 K/W on standard FR4). This enables 1.8× higher IF(AV) at 75 °C ambient - 1.6 A on FR4 vs. 2.9 A on ceramic - critical for high-density power modules.
