Product details
Overview
PMEG3030CER-QX from Nexperia is a 30 V, 3 A planar Schottky barrier rectifier in CFP3 (SOD123W) surface-mount package, designed for low-voltage rectification and reverse polarity protection in automotive-grade power circuits. It delivers VF = 510–580 mV at IF = 3 A (25 °C), IR ≤ 50 µA at VR = 30 V (25 °C), and operates up to Tj = 175 °C with AEC-Q101 qualification.
For engineers reviewing the PMEG3030CER-QX datasheet, PMEG3030CER-QX pinout, PMEG3030CER-QX application, or PMEG3030CER-QX equivalent, key selection criteria include forward voltage drop at 3 A, thermal resistance to solder point (Rth(j-sp) = 18 K/W), reverse leakage at 125 °C (8–25 mA), and AEC-Q101 compliance for under-hood automotive use.
Technical Context
This Schottky rectifier uses a planar silicon die with clip-bond interconnection to minimize parasitic inductance and enhance thermal transfer from junction to cathode tab. Its low VF and negligible reverse recovery (trr = 5.5 ns) enable high-efficiency operation in DC-DC converters and SMPS topologies where switching losses must be minimized.
The device is optimized for continuous conduction mode (δ = 0.5, f = 20 kHz square wave) with IF(AV) = 3 A at Tsp ≤ 161 °C, and supports non-repetitive surge currents up to IFSM = 50 A (tp = 8.3 ms). Thermal design relies on Rth(j-sp) = 18 K/W to a 1 cm² cathode pad, not ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 30 V maximum reverse voltage - sets upper limit for blocking capability in 24 V automotive systems. |
| IF(AV) | 3 A average forward current - supports sustained 3 A load in DC-DC output stages with proper PCB copper area. |
| VF @ 3 A | 510–580 mV at 25 °C - enables <1.75 W conduction loss per diode at full load, critical for thermal budget in compact layouts. |
| IR @ 30 V, 125 °C | 8–25 mA - defines worst-case reverse leakage power dissipation in hot environments (e.g., engine bay). |
| Rth(j-sp) | 18 K/W - quantifies thermal path efficiency from junction to solder point; requires ≥1 cm² cathode copper for rated current. |
| trr | 5.5 ns - eliminates reverse recovery tail, reducing EMI and enabling >1 MHz switching in synchronous rectifiers. |
| AEC-Q101 Qualified | Qualified for automotive applications - meets stress test requirements for temperature cycling, HTRB, and ESD per AEC standard. |
Pinout & Package
Package: CFP3 (SOD123W), 2.6 mm × 1.7 mm × 1.0 mm body, flat lead SMD plastic package with exposed cathode tab for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode (K) | Connected to PCB copper pour for heat sinking; marking bar identifies this terminal - critical for polarity-sensitive reverse protection. |
| 2 | Anode (A) | Input-side connection; low-inductance clip bond ensures minimal voltage overshoot during fast turn-off in SMPS freewheeling paths. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | VF = 510 mV typ. at 3 A/25 °C - reduces conduction loss by ~30% vs. comparable 45 V Schottkys, improving system efficiency. |
| Clip bond construction | Enables 4.2 A peak forward current (IF) and 50 A non-repetitive surge - supports transient overload without bond wire failure. |
| AEC-Q101 qualification | Validated for automotive under-hood use - includes HTGB, H3TRB, and temperature cycling tests per AEC standard. |
| Small flat SMD footprint | SOD123W outline (2.6 × 1.7 mm) - allows high-density placement in space-constrained ADAS and infotainment power rails. |
| Thermal resistance to solder point | Rth(j-sp) = 18 K/W - enables direct thermal coupling to PCB ground plane, eliminating need for external heatsinks in 3 A designs. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Input Protection |
|---|---|
|
Use Scenario: Reverse polarity protection on 12 V battery input to BCM microcontroller power rail. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage during jump-start misconnection. Use Value: With VF < 580 mV and IR < 25 mA at 125 °C, it limits standby power loss to <1.8 mW while surviving 175 °C junction temperature. |
Use Scenario: Input OR-ing diode in dual-source USB-C PD adapter (battery + wall adapter). IC Role / Device Role / Timing Role: Low-loss power path selector ensuring seamless source switchover without voltage droop. Use Value: 5.5 ns trr and 510 mV VF enable clean, fast switching between sources with <100 ns dead time and no shoot-through risk. |
| Automotive LED Headlamp Driver | Industrial 24 V DC-DC Buck Converter Output Rectifier |
|
Use Scenario: Freewheeling path in high-side buck controller driving 40 W LED array. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in low-VF, high-frequency (>500 kHz) topology. Use Value: Rth(j-sp) = 18 K/W allows direct mounting to aluminum-backed PCB, maintaining Tj < 150 °C at 3 A continuous with no heatsink. |
Use Scenario: Secondary-side rectifier in isolated 24 V → 5 V flyback converter for PLC I/O modules. IC Role / Device Role / Timing Role: Low-loss output rectifier minimizing conduction loss in thermally constrained industrial enclosures. Use Value: 30 V VR rating provides 2× margin over 24 V bus transients; 8–25 mA IR at 125 °C ensures stable operation in sealed cabinets. |
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-3EYH03-M3/54 | Same 30 V/3 A rating, VF = 540 mV typ., but TO-277 package (larger, higher Rth(j-a)) and no AEC-Q101 qualification. | Lacks automotive qualification; suitable only for industrial/commercial use with adequate heatsinking. | Select when cost is prioritized over automotive compliance and board space is not constrained. |
| ON Semiconductor NSR30C30NXT5G | CFP3 package, AEC-Q101 qualified, VF = 520 mV typ., but IR = 100 µA at 30 V/25 °C (2× higher than PMEG3030CER-QX). | Higher reverse leakage reduces efficiency in battery-critical applications like always-on modules. | Select when slightly lower VF is acceptable and leakage sensitivity is low; verify thermal derating at 125 °C. |
Compared with VS-3EYH03-M3/54 and NSR30C30NXT5G, PMEG3030CER-QX offers the lowest combination of VF, IR, and Rth(j-sp) in an AEC-Q101-qualified CFP3 package - making it optimal for space- and thermal-constrained automotive power rails requiring long-term reliability.

FAQ
What is the maximum allowable solder point temperature for PMEG3030CER-QX during operation?
The maximum solder point temperature (Tsp) is 161 °C for δ = 0.5 square-wave operation and 158 °C for DC (δ = 1), as defined in the limiting values table. Exceeding these temperatures risks permanent degradation of the clip bond interface and thermal performance.
Can PMEG3030CER-QX be used in a synchronous rectifier configuration?
No - PMEG3030CER-QX is a passive Schottky rectifier, not a controlled switch. It lacks gate terminals and cannot be actively driven. However, its 5.5 ns trr and low VF make it suitable as a high-performance freewheeling or OR-ing diode in synchronous topologies where external FETs handle active switching.
How does the CFP3 package improve thermal performance versus standard SOD-123?
The CFP3 (SOD123W) package features an enlarged cathode pad and internal clip bonding that reduces Rth(j-sp) to 18 K/W - 30% lower than typical SOD-123 devices. This allows 3 A continuous current with only a 1 cm² copper pad, whereas standard SOD-123 would require larger copper or forced air cooling.
Is the marking code 'N6' sufficient to identify PMEG3030CER-QX on the PCB?
Yes - per Table 4 of the datasheet, 'N6' is the unique marking code for PMEG3030CER-QX. The cathode is indicated by a bar adjacent to pin 1, and the 'N6' marking appears on the top surface of the CFP3 body, enabling visual and automated optical inspection verification.
