Product details
Overview
PMEG3020EXE from Nexperia is a planar Schottky barrier rectifier in CFP3-HP (SOD123HP) package, designed for low-voltage, high-efficiency power conversion. It delivers 2 A average forward current at 30 V reverse voltage, with typical forward voltage of 460 mV at 2 A and 25 °C, low leakage (15 µA at 30 V/25 °C), and robust 50 A non-repetitive surge capability - deployed in DC-DC converters and SMPS output stages.
For engineers reviewing the PMEG3020EXE datasheet, PMEG3020EXE pinout, PMEG3020EXE application, or PMEG3020EXE equivalent, key selection criteria include forward voltage drop at 2 A, thermal resistance to solder point (6 K/W), reverse leakage at 125 °C (8–25 mA), junction temperature limit (175 °C), and SOD123HP footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky rectifier uses a planar metal-semiconductor junction optimized for minimal conduction loss and fast switching. Its clip-bond construction enhances thermal transfer from die to exposed cathode tab, enabling higher power density than standard SOD123 devices.
The device exhibits ultra-fast recovery (trr ≤ 7 ns ramp, ≤ 5 ns step) and low diode capacitance (50 pF at 10 V), making it suitable for high-frequency (>1 MHz) synchronous rectification and reverse polarity protection where low Qrr (<2.5 nC) and minimal VFRM (<380 mV) reduce switching losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 30 V - Maximum blocking voltage before breakdown; defines safe operating range in 24 V rail protection and 12 V DC-DC outputs. |
| IF(AV) (Avg. Forward Current) | 2 A - Continuous DC current handling at Tsp ≤ 168 °C; supports compact 2 A buck converter outputs without forced air. |
| VF @ 2 A / 25 °C | 460–520 mV - Low conduction loss reduces I²R heating; enables >95% efficiency in 5 V/2 A point-of-load designs. |
| IR @ 30 V / 125 °C | 8–25 mA - Elevated leakage at high temp impacts standby power; critical for always-on battery-powered systems. |
| Rth(j-sp) | 6 K/W - Thermal resistance from junction to cathode solder point; enables direct thermal coupling to large copper pour for passive cooling. |
| Qrr | 2.5 nC - Reverse recovery charge; determines turn-off loss in high-frequency switching; lower than comparable 3 A Schottkys. |
| trr (ramp) | 7 ns - Fast recovery minimizes dead-time loss in synchronous rectifiers operating above 500 kHz. |
Pinout & Package
Encapsulated in CFP3-HP (SOD123HP) surface-mount package: 2.80 mm × 1.80 mm × 0.90 mm body with exposed cathode pad for thermal enhancement. Standard footprint per Figure 16 (Nexperia doc 23-11-29), featuring 1 cm² cathode mounting pad recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to load ground or negative rail; marked by bar on top surface; serves as primary thermal path to PCB. |
| 2 | Anode (A) | Connected to input/source side; carries full forward current; electrically isolated from heatsink function. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 460 mV typ. @ 2 A/25 °C - Reduces conduction loss by ~30% vs. legacy Schottkys, directly improving light-load efficiency. |
| Exposed cathode thermal pad | 6 K/W Rth(j-sp) - Enables 1.3 W power dissipation at Tamb = 25 °C with 1 cm² copper, eliminating need for external heatsinks. |
| High surge robustness | 50 A IFSM (8.3 ms half-sine) - Withstands inrush in hot-plug 24 V systems without derating or parallel devices. |
| Ultra-low Qrr | 2.5 nC - Limits turn-off energy loss in 1–3 MHz DC-DC controllers, reducing MOSFET gate driver stress. |
| Step/ramp recovery optimization | trr ≤ 5 ns (step), ≤ 7 ns (ramp) - Supports zero-voltage switching (ZVS) topologies with minimal ringing in high-side rectification. |
Applications
| DC-DC Converter Output Rectification | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Secondary-side rectification in 5 V/2 A synchronous buck converter operating at 1 MHz. IC Role / Device Role / Timing Role: Low-loss freewheeling path replacing MOSFET body diode; conducts during low-side switch off-time.

Use Scenario: Input protection for USB-C PD sink circuitry powered from 20 V adapter. IC Role / Device Role / Timing Role: Series-connected anode-to-input, cathode-to-system rail; blocks reverse current during miswiring. Use Value: 30 V VR rating covers full USB PD 3.1 range; 25 mA IR at 125 °C ensures <10 µW standby loss in automotive infotainment. |
| SMPS Auxiliary Supply | Low-Power Standby Regulation |
|
Use Scenario: +12 V auxiliary winding rectification in 400 W server PSU main transformer. IC Role / Device Role / Timing Role: High-reliability, low-leakage rectifier feeding +12 V fan and control logic rails. Use Value: 175 °C Tj rating allows operation in confined transformer vicinity; 50 A surge withstand prevents failure during cold-start. |

IC Role / Device Role / Timing Role: Output rectifier for 100 kHz flyback supplying 100 mA continuous + 500 mA peak. Use Value: 15 µA IR at 25 °C keeps no-load power below 0.5 mW; 7 ns trr avoids cross-conduction in burst-mode operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VSSAF2M4HM3/H | Same 30 V/2 A rating but SOD123 (not HP); Rth(j-a) = 200 K/W vs. 115 K/W; VF = 490 mV min. | Lacks exposed thermal pad; unsuitable for >1.2 W continuous dissipation without airflow. | Prefer when board space is constrained but thermal budget allows higher ambient rise. |
| ON Semiconductor NSR20F30NXT5G | 30 V/2 A, VF = 450 mV typ., but SOD-123FL package; Rth(j-sp) not specified; Qrr = 3.5 nC. | Higher Qrr increases switching loss in >1 MHz designs; no published Rth(j-sp) limits thermal design confidence. | Select only if footprint compatibility with legacy SOD-123FL is mandatory and frequency <500 kHz. |
Compared with VSSAF2M4HM3/H and NSR20F30NXT5G, PMEG3020EXE offers superior thermal performance via its clip-bonded cathode pad (6 K/W), lower Qrr for high-frequency efficiency, and verified 125 °C leakage - making it optimal for thermally dense, high-switching-frequency DC-DC and protection circuits.

FAQ
What is the maximum allowable solder point temperature during reflow for PMEG3020EXE?
The device is qualified for standard lead-free reflow per J-STD-020. Peak solder point temperature must not exceed 260 °C for ≤ 30 seconds, with ramp rates ≤ 3 °C/s pre-peak. The cathode tab's thermal mass requires careful profiling to avoid localized overheating while ensuring full solder joint formation on the 1 cm² pad.
Can PMEG3020EXE replace a standard SOD-123 Schottky in existing layouts?
Yes - CFP3-HP (SOD123HP) shares identical 2.80 mm × 1.80 mm outline and 0.90 mm height with standard SOD-123, but features an extended cathode pad. Existing footprints require minor land pattern adjustment (enlarged cathode pad to 1 cm²) to realize full thermal benefit; mechanical fit is guaranteed.
How does PMEG3020EXE perform under reverse bias at elevated temperature?
At 125 °C and 30 V reverse bias, IR is specified 8–25 mA - significantly higher than room-temperature leakage (15–50 µA). This must be accounted for in battery-powered standby designs, where total system quiescent current could increase by >20 µA per diode in multi-rail systems.
Is PMEG3020EXE suitable for automotive applications?
No - this device is not AEC-Q200 qualified. Nexperia explicitly states in its legal disclaimers that PMEG3020EXE is non-automotive qualified and not tested to automotive reliability or temperature requirements. Use in automotive systems requires formal qualification and validation by the end customer.
