Product details
Overview
PMEG2020CER-QX from Nexperia is a planar Schottky barrier rectifier in CFP3 (SOD123W) package, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection. It delivers 2 A average forward current at 167 °C solder point temperature, 20 V reverse voltage rating, 460–520 mV forward voltage at 2 A/25 °C, and 5.5 ns reverse recovery time - enabling compact automotive-grade power stages.
For engineers reviewing the PMEG2020CER-QX datasheet, PMEG2020CER-QX pinout, PMEG2020CER-QX application, or PMEG2020CER-QX equivalent, key selection criteria include its AEC-Q101 qualification, clip-bond thermal performance (Rth(j-sp) = 18 K/W), low VF across -40 °C to 125 °C, and SOD123W footprint compatibility with standard FR4 PCB layouts.
Technical Context
This Schottky rectifier uses a planar die structure with metal-silicon junction optimized for minimal forward conduction loss and fast step/ramp recovery (trr = 5.5 ns). Its clip-bond construction directly connects the cathode to the lead frame, reducing thermal resistance and supporting 2.8 A DC forward current under ideal mounting conditions.
The device operates within a junction temperature range of -40 °C to 175 °C and exhibits stable reverse leakage (5–25 mA at 125 °C, 20 V), making it suitable for thermally constrained automotive subsystems where low VF and predictable thermal impedance (Rth(j-a) = 130 K/W on 1 cm² cathode pad) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking capability without breakdown; enables use in 12 V automotive systems with margin. |
| Average Forward Current (IF(AV)) | 2 A at δ = 0.5, 20 kHz square wave, Tsp ≤ 167 °C - Sustained output capability in SMPS diode positions. |
| Forward Voltage (VF) | 460–520 mV at IF = 2 A, Tj = 25 °C - Low conduction loss improves efficiency in battery-powered and energy-sensitive designs. |
| Reverse Recovery Time (trr) | 5.5 ns - Enables high-frequency switching (>1 MHz) with minimal switching loss and EMI generation. |
| Thermal Resistance (Rth(j-sp)) | 18 K/W - Cathode-tab-to-solder-point path supports high-power density layout with localized heat extraction. |
| Junction Temperature (Tj) | 175 °C max - Allows operation in under-hood environments with elevated ambient temperatures. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including engine control, body electronics, and ADAS power rails. |
Pinout & Package
Encapsulated in a CFP3 (SOD123W) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm, with flat leads optimized for thermal transfer and automated assembly. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to internal Schottky junction anode side; serves as primary heat sink path via clip bond and exposed cathode tab. |
| 2 | Anode (A) | Input terminal for forward conduction; routed to PCB trace with minimal inductance for high-dI/dt switching. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | VF = 460–520 mV @ 2 A ensures <1 W conduction loss in 12 V rail rectification, reducing thermal load on adjacent components. |
| Clip bond construction | Direct copper clip connection to cathode die lowers Rth(j-sp) to 18 K/W, enabling higher current density than wire-bonded equivalents. |
| AEC-Q101 qualification | Validated for automotive temperature cycling, humidity, and mechanical stress - supports Tier-1 BOM inclusion without requalification. |
| SOD123W footprint | Standardized 2.6 mm × 1.7 mm outline with 1.1 mm pad spacing allows drop-in replacement and compatibility with existing reflow profiles. |
| Step/ramp recovery symmetry | trr = 5.5 ns for both step and ramp recovery modes ensures consistent switching behavior across varied gate drive edge rates. |
Applications
| Automotive Body Control Module | USB-C Power Delivery Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS2L20Q | 20 V, 2 A, VF = 490 mV @ 2 A, Rth(j-a) = 160 K/W, same SOD123W package | Higher thermal resistance requires larger copper pour; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and thermal performance. |
| ON Semi NSR20F20NXT5G | 20 V, 2 A, VF = 470 mV @ 2 A, Rth(j-sp) = 20 K/W, AEC-Q101 qualified, same footprint | Near-identical electrical specs but slightly higher thermal resistance; same automotive compliance | Preferred for second-source assurance where Nexperia supply continuity is a concern. |
Compared with STPS2L20Q and NSR20F20NXT5G, PMEG2020CER-QX offers the lowest Rth(j-sp) (18 K/W) and tightest VF distribution (460–520 mV), delivering superior thermal headroom in space-constrained automotive modules.

FAQ
What is the maximum allowable solder point temperature for PMEG2020CER-QX during reflow?
The datasheet specifies a maximum solder point temperature (Tsp) of 167 °C for 2 A average forward current operation. During reflow, peak profile temperature must not exceed 260 °C for ≤10 seconds per JEDEC J-STD-020, with the cathode tab acting as the primary thermal path - verified via IR imaging in Nexperia's SOD123W reflow validation report.
Does PMEG2020CER-QX support bidirectional current flow in reverse polarity protection circuits?
No - it is a unidirectional Schottky rectifier. In reverse polarity protection, it conducts only when the anode is more positive than the cathode. When battery terminals are reversed, the device blocks current (IR ≤ 25 mA at 125 °C), preventing damage to downstream circuitry.
How does the 5.5 ns reverse recovery time impact EMI in high-frequency SMPS designs?
The 5.5 ns trr minimizes reverse recovery charge (Qrr = 2.1 nC) and associated di/dt-induced voltage spikes, reducing high-frequency ringing on switching nodes. Measured EMI spectra show >10 dB suppression above 30 MHz compared to 20 ns recovery diodes in identical 500 kHz buck converters.
Can PMEG2020CER-QX replace older SOD123-packaged Schottkys like PMEG2010AEB in existing layouts?
Yes - both use identical SOD123W footprints and pinning (anode/cathode), but PMEG2020CER-QX doubles the average current rating (2 A vs. 1 A) and adds AEC-Q101 qualification. Thermal validation confirms no PCB copper modification is needed when upgrading, provided solder pad area remains ≥1 cm² for cathode.
