Product details
Overview
PMEG2030CER-QX from Nexperia is a planar Schottky barrier rectifier in CFP3 (SOD123W) package, rated for 20 V reverse voltage and 3 A average forward current at Tsp ≤ 161 °C, with typical forward voltage of 510 mV at 3 A and 25 °C. It serves as a low-loss power rectifier in automotive-grade DC/DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG2030CER-QX datasheet, PMEG2030CER-QX pinout, PMEG2030CER-QX application, or PMEG2030CER-QX equivalent, key selection criteria include its AEC-Q101 qualification, clip-bond thermal performance, low VF at high junction temperature, and SOD123W footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode uses a planar metal-semiconductor junction to achieve fast recovery (trr = 5.5 ns), negligible minority-carrier storage, and stable reverse leakage (IR = 5–25 mA at 125 °C, 20 V). Its clip-bond construction reduces thermal resistance to Rth(j-sp) = 18 K/W, enabling higher power density than wire-bonded equivalents.
The device operates across –40 °C to +175 °C junction temperature, with forward voltage varying from 550 mV at –40 °C to 455 mV at 125 °C (IF = 3 A), supporting wide-temperature automotive systems. Diode capacitance is 145 pF at 1 V and 51 pF at 10 V (f = 1 MHz), minimizing switching losses in high-frequency SMPS.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS3L20Q | Same 20 V / 3 A rating, but TO-277 package (larger footprint, higher Rth(j-a) = 45 K/W). | Less suitable for ultra-thin automotive modules due to 1.8 mm height and manual soldering constraints. | Select when board space allows larger package and thermal management relies on ambient convection over solder-pad conduction. |
| ON Semi NSR20F20NT1G | 20 V / 2 A rating, SOD-123 package, VF = 520 mV @ 2 A - lower current capacity and no AEC-Q101 certification. | Not qualified for automotive use; limited to consumer-grade power supplies with <2 A load. | Choose only for cost-sensitive non-automotive applications where 1 A derating and absence of automotive qualification are acceptable. |
Compared with STPS3L20Q and NSR20F20NT1G, PMEG2030CER-QX offers superior thermal performance in minimal area, AEC-Q101 assurance for automotive deployment, and verified 3 A continuous capability - making it optimal for space-constrained, high-reliability 12–24 V systems.

FAQ
Is PMEG2030CER-QX suitable for synchronous rectification replacement?
No - it is a passive Schottky rectifier, not a synchronous rectifier IC or MOSFET driver. However, its 5.5 ns trr and low VF make it an effective drop-in replacement for standard diodes in flyback or boost converters where active synchronous control is unnecessary or cost-prohibitive.
What is the maximum allowable solder point temperature during reflow?
The absolute maximum solder point temperature is not specified separately, but the device is qualified for standard lead-free reflow profiles. The datasheet specifies Tsp ≤ 161 °C for 3 A average current derating; peak reflow temperature must comply with IPC/JEDEC J-STD-020 (≤ 260 °C for ≤ 30 s), and the CFP3 package is rated for such profiles per Nexperia's SOD123W footprint guidelines.
Does the marking 'N5' indicate RoHS or AEC-Q101 compliance?
The 'N5' marking is a manufacturer-specific code for PMEG2030CER-QX and does not encode compliance status. AEC-Q101 qualification and RoHS compliance are documented in the product data sheet and ordering information - both are confirmed for this part number, independent of the top-side marking.
Can PMEG2030CER-QX handle 20 V reverse bias continuously at 125 °C junction temperature?
Yes - the datasheet specifies IR = 5–25 mA at VR = 20 V and Tj = 125 °C, confirming stable blocking capability under those conditions. Thermal design must ensure Tj does not exceed 175 °C, and layout should provide adequate copper area to maintain safe operating temperature.
