Product details
Overview
PMEG3020EXE-QX from Nexperia is a 30 V, 2 A automotive-qualified Schottky barrier rectifier in CFP3-HP (SOD123HP) package, designed for low-loss unidirectional current flow in DC/DC converters and reverse polarity protection circuits. It delivers 460 mV typical forward voltage at 2 A and 25 °C, supports 50 A non-repetitive surge current, and operates up to 175 °C junction temperature.
For engineers reviewing the PMEG3020EXE-QX datasheet, PMEG3020EXE-QX pinout, PMEG3020EXE-QX application, or PMEG3020EXE-QX equivalent, key selection criteria include forward voltage vs. temperature performance, thermal resistance to solder point (6 K/W), AEC-Q101 qualification status, and SOD123HP footprint compatibility with high-density automotive PCB layouts.
Technical Context
This planar Schottky diode uses metal–semiconductor junction technology to achieve fast switching with near-zero reverse recovery charge (2.5 nC) and sub-10 ns reverse recovery time. Its clip-bond construction enhances thermal conduction from junction to exposed cathode tab.
The device is characterized for operation under pulsed conditions to maintain stable junction temperature, with limiting values defined per IEC 60134. Thermal runaway mitigation is required due to temperature-dependent reverse leakage growth-reverse power loss becomes significant above 100 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 30 V maximum reverse voltage - defines safe blocking capability in 24 V automotive systems with transient margin. |
| IF(AV) | 2 A average forward current - rated at δ = 0.5, 20 kHz square wave, Tsp ≤ 168 °C - supports continuous operation in SMPS output stages. |
| VF @ 2 A | 460 mV typical at 25 °C - enables <1 W conduction loss at full load, critical for thermally constrained modules. |
| IR @ 125 °C | 8–25 mA reverse leakage - impacts standby power in reverse polarity protection; requires thermal derating above 85 °C ambient. |
| Rth(j-sp) | 6 K/W junction-to-solder-point - enables direct thermal coupling to large copper pads, reducing thermal impedance by >80% vs. standard SOD123. |
| Qrr | 2.5 nC reverse recovery charge - minimizes switching loss and EMI in high-frequency (>500 kHz) DC/DC topologies. |
| trr | 5 ns step recovery time - ensures clean commutation in synchronous rectifier and flyback applications. |
Pinout & Package
Encapsulated in CFP3-HP (SOD123HP) surface-mount plastic package: 2.80 mm × 1.80 mm × 0.90 mm body with exposed cathode heatsink pad. Standard footprint per Figure 16 (Nexperia doc 23-11-29); recommended stencil thickness 0.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main current exit terminal; marked with bar; connects to exposed thermal pad for low-Rth path to PCB. |
| 2 | Anode (A) | Current entry terminal; electrically isolated from thermal pad; routed to input or switch node. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high temperature | 380–470 mV at 2 A and 125 °C - maintains efficiency in under-hood environments where ambient exceeds 85 °C. |
| AEC-Q101 qualified | Stress-tested per automotive discrete semiconductor standard - validated for temperature cycling, HTRB, and ESD robustness. |
| High surge robustness | 50 A IFSM (8.3 ms half-sine) - withstands load dump transients and inrush currents without degradation. |
| Optimized thermal interface | Exposed cathode pad with Rth(j-sp) = 6 K/W - enables >1.3 W power dissipation on 1 cm² copper pad at 25 °C ambient. |
| Low capacitance | 50 pF at VR = 10 V - reduces switching noise and improves EMI performance in high-frequency converters. |

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-2EY30-M3/54 | Same 30 V/2 A rating but TO-277A package (larger footprint, higher Rth(j-a)) | Lacks AEC-Q101 qualification; not automotive-grade | Select only for cost-sensitive industrial designs where thermal margin exceeds 25 °C and qualification is not required. |
| ON Semiconductor NSR20F30HT1G | SOD-123FL package (no exposed pad); Rth(j-a) = 125 K/W vs. 115 K/W for PMEG3020EXE-QX | Qualified to AEC-Q101 but lower thermal performance limits continuous current to 1.5 A at 70 °C ambient | Prefer when board space is constrained and peak power dissipation remains below 0.8 W. |
Compared with VS-2EY30-M3/54 and NSR20F30HT1G, PMEG3020EXE-QX uniquely combines AEC-Q101 compliance, 6 K/W junction-to-solder-point thermal resistance, and 2 A continuous rating in SOD123HP-enabling smaller, cooler-running automotive power rails without derating.

FAQ
What is the maximum allowable solder point temperature for PMEG3020EXE-QX during reflow?
The device is rated for Tsp ≤ 168 °C under average forward current conditions (δ = 0.5, 20 kHz). Reflow peak temperature must not exceed 260 °C for ≤ 30 seconds per J-STD-020, with thermal profile validated using the recommended SOD123HP footprint (Figure 16) and 0.1 mm stencil thickness.
Can PMEG3020EXE-QX replace standard SOD-123 Schottky diodes in existing designs?
Yes, it is footprint-compatible with standard SOD-123 but offers superior thermal performance due to its exposed cathode pad. To realize full benefit, redesign the PCB to include ≥1 cm² copper area connected to pin 1 (cathode), and verify thermal relief patterns do not impede solder wetting to the thermal pad.
How does reverse leakage behave at elevated temperatures?
Reverse current increases exponentially with junction temperature: IR = 15–50 µA at 25 °C, rising to 8–25 mA at 125 °C. In reverse polarity protection applications above 85 °C ambient, thermal design must limit Tj to ≤100 °C to keep leakage below 1 mA and avoid excessive standby power loss.
Is PMEG3020EXE-QX suitable for synchronous rectification?
No-it is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier IC. However, its low Qrr (2.5 nC) and fast trr (5 ns) make it an effective replacement for slower diodes in freewheeling paths where gate drive complexity must be avoided, especially in compact 1–3 A DC/DC outputs.
