Product details
Overview
PMEG3030EXE-QX from Nexperia is a 30 V, 3 A planar Schottky barrier rectifier in a CFP3-HP (SOD123HP) surface-mount package, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection in automotive power rails. It delivers 500 mV typical forward voltage at 3 A and 25 °C, supports 50 A non-repetitive surge current, and is qualified to AEC-Q101 for under-hood applications.
For engineers reviewing the PMEG3030EXE-QX datasheet, PMEG3030EXE-QX pinout, PMEG3030EXE-QX application, or PMEG3030EXE-QX equivalent, key selection criteria include its low VF (500 mV typ.), low IR (15 µA typ. at 30 V/25 °C), thermal resistance to solder point (6 K/W), AEC-Q101 qualification, and SOD123HP footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky rectifier uses a planar metal–semiconductor junction architecture optimized for minimal forward conduction loss and fast switching with negligible reverse recovery charge (Qrr = 2.5 nC). Its clip-bond construction enhances thermal transfer from the die to the exposed cathode tab, enabling stable operation up to 175 °C junction temperature.
The device operates without minority-carrier storage, eliminating reverse recovery time (trr < 7 ns) and associated switching losses-critical for high-frequency SMPS topologies. Its capacitance (145 pF at 1 V) and low leakage support efficient operation in low-power consumption and battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 30 V maximum reverse voltage - sets safe operating limit for 24 V automotive rail clamping and reverse polarity protection. |
| IF(AV) | 3 A average forward current - supports continuous 36 W dissipation in standard FR4 layout with δ = 0.5 duty cycle. |
| VF | 500 mV typical at IF = 3 A, 25 °C - reduces conduction loss by ~30% vs. comparable silicon diodes, improving system efficiency. |
| IR | 15 µA typical at VR = 30 V, 25 °C - enables low standby power in always-on automotive modules. |
| Rth(j-sp) | 6 K/W junction-to-solder-point - allows direct thermal coupling to large copper pour, critical for thermal reliability in engine control units. |
| Qrr | 2.5 nC reverse recovery charge - eliminates switching tail current, reducing EMI and MOSFET stress in synchronous buck converters. |
| Tj(max) | 175 °C maximum junction temperature - meets under-hood thermal requirements per AEC-Q101 Grade 1. |
Pinout & Package
Encapsulated in a CFP3-HP (SOD123HP) plastic surface-mount package measuring 2.80 mm × 1.80 mm × 0.90 mm, with an exposed cathode pad for enhanced thermal performance and standard reflow-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main current sink terminal; marked with bar; connects directly to heatsink plane for lowest Rth(j-sp). |

Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 500 mV typ. at 3 A ensures ≤1.5 W conduction loss in 24 V input buck stages, extending battery runtime. |
| High surge robustness | 50 A IFSM (8.3 ms half-sine) withstands load dump transients in 12 V/24 V automotive systems without failure. |
| Exposed cathode thermal pad | 6 K/W Rth(j-sp) enables >1.3 W power dissipation on 1 cm² copper, eliminating need for external heatsinks. |
| AEC-Q101 qualification | Qualified for automotive Grade 1 (−40 °C to +125 °C ambient), including HTGB, HTRB, and temperature cycling tests. |
| Low reverse recovery charge | 2.5 nC Qrr minimizes shoot-through risk and gate driver stress in synchronous rectification circuits. |

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-3EPH03-M3/86A | Same 30 V/3 A rating but TO-277 package; higher Rth(j-a) (35 K/W vs. 115 K/W); no AEC-Q101 qualification. | Not suitable for automotive under-hood use; limited to industrial ambient ≤85 °C. | Select only if board space permits larger TO-277 and AEC compliance is not required. |
| ON Semiconductor NSR3030P2T5G | SOD-123 package (not SOD123HP); 600 mV VF at 3 A; 20 µA IR at 30 V/25 °C; AEC-Q101 qualified. | Higher conduction loss and leakage reduce efficiency in battery-critical designs. | Acceptable for cost-sensitive automotive interiors where 50 mV VF penalty and 33% higher IR are tolerable. |
Compared with VS-3EPH03-M3/86A and NSR3030P2T5G, PMEG3030EXE-QX offers superior thermal performance via its clip-bond SOD123HP package, lower VF and IR, and verified AEC-Q101 Grade 1 compliance-making it the optimal choice for thermally constrained, high-reliability automotive power rails.

FAQ
What is the maximum allowable solder point temperature for PMEG3030EXE-QX during reflow?
The device is rated for a maximum solder point temperature (Tsp) of 163 °C at δ = 0.5 duty cycle, per Table 5 limiting values. Reflow profiles must ensure peak temperature at the cathode pad does not exceed this value to avoid bond degradation or delamination. Recommended stencil thickness is 0.1 mm per Figure 16.
Does PMEG3030EXE-QX support bidirectional current flow?
No. As a Schottky barrier rectifier, PMEG3030EXE-QX conducts current only from anode to cathode. Reverse current is limited to leakage (≤25 mA at 125 °C), and the device is not rated for reverse conduction. It must be oriented correctly in series with the power path to block reverse polarity.
How does the CFP3-HP package improve thermal performance over standard SOD-123?
The CFP3-HP (SOD123HP) package features a copper clip-bond structure and an exposed cathode pad that reduces junction-to-solder-point thermal resistance to 6 K/W-nearly 5× better than standard SOD-123. This enables higher continuous current handling on compact PCBs without thermal vias or external heatsinks.
Is PMEG3030EXE-QX compatible with lead-free reflow processes?
Yes. The device is qualified for lead-free reflow per J-STD-020, with a maximum peak temperature of 260 °C for ≤30 seconds. Its moisture sensitivity level (MSL) is 1, meaning it can be stored indefinitely at ≤30 °C/85% RH without baking prior to assembly.
