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.

Key Specifications

Avg. Forward Current (IF(AV)) 3 A - Sustained DC or pulsed rectification capacity under δ = 0.5, 20 kHz square wave, Tsp ≤ 161 °C.
Forward Voltage (VF) 510 mV typ. @ 3 A, 25 °C - Low conduction loss enabling >95% efficiency in low-voltage DC/DC stages.
Reverse Recovery Time (trr) 5.5 ns - Ultrafast recovery minimizes switching loss and EMI in >500 kHz SMPS designs.
Thermal Resistance (Rth(j-sp)) 18 K/W - Low junction-to-solder-point resistance enables reliable operation on FR4 with 1 cm² cathode pad.
AEC-Q101 Qualified Yes - Validated for automotive applications including engine control, body electronics, and ADAS power supplies.
Package CFP3 (SOD123W) - 2.6 mm × 1.7 mm × 1.0 mm surface-mount outline with flat leads for automated assembly and thermal relief.

Pinout & Package

Encapsulated in a CFP3 (SOD123W) plastic surface-mount package measuring 2.6 mm × 1.7 mm × 1.0 mm, with tin-plated flat leads optimized for reflow soldering and thermal transfer via cathode tab.

Pin/Terminal Circuit Role Design Meaning
1 (Marked side) Cathode (K) Negative output terminal; marked by bar; connects to ground or return path; primary thermal interface via large copper pad.
2 Anode (A) Positive input terminal; accepts input voltage; carries full forward current during conduction phase.

Key Features

Feature Design Value
Low forward voltage VF = 510 mV @ 3 A, 25 °C - Reduces conduction loss by ≥30% vs. standard silicon diodes in 5–12 V rails.
Clip-bond construction Rth(j-sp) = 18 K/W - Enables 4.2 A peak forward current (IF) and 50 A non-repetitive surge (IFSM) without thermal runaway.
AEC-Q101 qualification Validated per stress test standard for discrete semiconductors - Ensures reliability in automotive under-hood environments.
Ultra-low reverse recovery trr = 5.5 ns - Eliminates reverse recovery tail, reducing switching node ringing and gate driver stress in synchronous rectifiers.
Wide temperature operation Tj = –40 °C to +175 °C - Maintains stable VF and IR across engine bay thermal cycles.

Use Scenario: Battery reverse protection and low-loss charging path in coin-cell or Li-ion powered wireless sensors.

IC Role / Device Role / Timing Role: Standby isolation element with <8 µA reverse leakage at 25 °C, preserving battery shelf life.

Use Value: 8 µA max IR at 20 V and 25 °C extends 10-year battery life in always-on environmental monitors.

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.
