Product details
Overview
PMEG3020CER-QX from Nexperia is a 30 V, 2 A planar Schottky barrier rectifier in CFP3 (SOD123W) surface-mount package, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection in automotive power rails. It delivers VF = 460–520 mV at IF = 2 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 PMEG3020CER-QX datasheet, PMEG3020CER-QX pinout, PMEG3020CER-QX application, or PMEG3020CER-QX equivalent, key selection criteria include forward voltage at 2 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 die structure with clip-bond interconnection to minimize parasitic inductance and enhance thermal transfer from junction to cathode tab. Its low VF and absence of minority-carrier storage enable near-zero reverse recovery (trr = 5.5 ns), eliminating switching losses in high-frequency SMPS topologies.
The CFP3 package features an exposed cathode pad optimized for thermal conduction to PCB copper, supporting Ptot = 1.15 W on 1 cm² cathode pad (Tamb ≤ 25 °C). Junction-to-solder-point thermal resistance is specified at 18 K/W - critical for thermal design in space-constrained automotive modules.
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) | 2 A average forward current - supports continuous operation in 5–12 V DC/DC converters with δ = 0.5 square wave. |
| VF @ 2 A | 460–520 mV at 25 °C - enables >92% efficiency in 5 V → 3.3 V buck stages at full load. |
| IR @ 30 V, 125 °C | 8–25 mA reverse leakage - defines worst-case standby power loss in reverse-polarity protection circuits. |
| trr | 5.5 ns typical - eliminates tail current, enabling clean switching at ≥1 MHz in synchronous rectifier designs. |
| Rth(j-sp) | 18 K/W - quantifies thermal path from junction to cathode solder point, enabling accurate board-level thermal modeling. |
| Cd @ 10 V | 51 pF diode capacitance - limits high-frequency displacement current in RF-coupled gate drive or EMI-sensitive locations. |
Pinout & Package
The PMEG3020CER-QX is housed in a CFP3 (SOD123W) plastic surface-mount package measuring 2.6 mm × 1.7 mm × 1.0 mm, with an exposed cathode pad for enhanced thermal performance. The marking bar denotes the cathode end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main current return path; thermally coupled to PCB copper via exposed metal pad - primary heat dissipation node. |
| 2 | Anode (A) | Input terminal for forward conduction; electrically isolated from thermal pad - minimal thermal contribution. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | VF = 460 mV typ. at 2 A/25 °C - reduces conduction loss by ≥30% vs. standard silicon diodes in 12 V input rails. |
| AEC-Q101 qualified | Stress-tested per automotive discrete semiconductor standard - validated for engine control, body electronics, and ADAS power supplies. |
| Clip-bond construction | Eliminates wire bonds - improves current handling (IFSM = 50 A) and thermal reliability under thermal cycling. |
| Small flat SMD footprint | SOD123W outline (2.6 × 1.7 mm) - enables high-density layout in compact infotainment and lighting modules. |
| High junction temperature rating | Tj(max) = 175 °C - allows operation in under-hood environments without derating at ambient ≤ 125 °C. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Input Protection |

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 VR = 30 V, IF(AV) = 2 A, but VF = 550 mV min at 2 A; TO-277 package (larger, higher Rth(j-a)). | Lacks AEC-Q101 qualification; not recommended for automotive under-hood use. | Select only for cost-sensitive industrial non-automotive designs where thermal margin exceeds 25 °C. |
| ON Semiconductor NSR2030HT1G | VF = 450 mV typ. at 2 A, same CFP3 package, but IR = 100 µA at 30 V/25 °C (2× higher leakage). | Higher reverse leakage increases standby power in always-on automotive modules (e.g., CAN wake-up circuits). | Prefer for non-automotive consumer power adapters where leakage <100 µA is acceptable and AEC-Q101 not required. |
Compared with VS-2EY30-M3/54 and NSR2030HT1G, PMEG3020CER-QX uniquely combines AEC-Q101 qualification, lowest VF among CFP3 30 V/2 A Schottkys, and industry-leading Rth(j-sp) = 18 K/W - making it optimal for thermally constrained automotive power rails requiring zero-recovery performance.

FAQ
What is the maximum allowable solder point temperature for PMEG3020CER-QX during reflow?
The device is rated for Tsp ≤ 167 °C under δ = 0.5 square-wave conditions (per Table 5). For reflow, peak temperature must not exceed 260 °C for ≤ 30 seconds per J-STD-020, with thermal profile validated using the CFP3 footprint in Figure 16 - ensuring cathode pad reaches but does not exceed 167 °C transiently.
Can PMEG3020CER-QX replace a standard PN-junction diode in an existing 12 V automotive circuit?
Yes - with direct substitution in most cases. Its lower VF (≈460 mV vs. ≈700–900 mV for PN diodes) reduces power loss and heat generation. However, verify reverse leakage at operating temperature: at 125 °C, IR reaches 8–25 mA, which may exceed legacy design assumptions for standby current budgets.
Does PMEG3020CER-QX require a heatsink in a 2 A continuous application?
No external heatsink is required when mounted on an FR4 PCB with a 1 cm² cathode copper pad (per Table 5). At Tamb = 70 °C, the device sustains 2 A with junction temperature ≤ 155 °C - within its 175 °C rating - due to Rth(j-sp) = 18 K/W and low VF-induced self-heating.
How does the CFP3 package improve thermal performance over traditional SOD-123?
CFP3 (SOD123W) adds an exposed cathode pad and clip-bond die attachment, reducing Rth(j-sp) to 18 K/W versus ≈45–60 K/W for standard SOD-123. This 2.5× better thermal path lowers junction temperature by ≈45 °C at 2 A, directly extending lifetime and enabling higher ambient operation in automotive modules.
