Product details
Overview
PMEG050V030EPE-QZ from Nexperia is a 50 V, 3 A planar low forward voltage Schottky barrier rectifier in a CFP15B (SOT1289B) surface-mount package, designed for high-efficiency DC-to-DC conversion and automotive-grade freewheeling applications. It delivers typ. 460 mV VF at 3 A and 25 °C, supports 120 A non-repetitive peak forward current, and is qualified to AEC-Q101.
For engineers reviewing the PMEG050V030EPE-QZ datasheet, PMEG050V030EPE-QZ pinout, PMEG050V030EPE-QZ application, or PMEG050V030EPE-QZ equivalent, this device is selected for low-loss rectification in space-constrained automotive power rails where thermal performance, reverse polarity protection, and fast recovery (<12 ns) are critical.
Technical Context
This Schottky diode uses clip-bonding technology to achieve low thermal resistance (Rth(j-sp) = 3 K/W) and high power capability in an ultra-thin 5.8 × 4.3 × 0.95 mm SMD package. Its planar construction ensures stable junction temperature under pulsed conditions and enables reliable operation up to Tj = 175 °C.
The device exhibits minimal reverse recovery (trr = 12 ns step recovery), negligible stored charge (Qrr not specified but implied by Schottky architecture), and low diode capacitance (323 pF at VR = 1 V), making it suitable for high-frequency switching topologies including synchronous rectification and OR-ing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 50 V reverse voltage rating - defines maximum blocking capability in reverse-biased operation |
| IF(AV) | 3 A average forward current - sustainable continuous conduction with δ = 0.5 square wave at Tsp ≤ 174 °C |
| VF | 460–530 mV at IF = 3 A, 25 °C - enables <0.5 W conduction loss per diode in 12 V systems |
| IR | 35–100 µA at VR = 50 V, 25 °C - ensures low leakage in reverse-biased protection schemes |
| trr | 12 ns step recovery - minimizes switching losses and EMI in >100 kHz SMPS designs |
| Rth(j-sp) | 3 K/W - enables efficient heat transfer from junction to cathode solder point on PCB |
| IFS M | 120 A non-repetitive peak forward current - supports surge handling in motor drive flyback paths |
Pinout & Package
Encapsulated in a thermally enhanced CFP15B (SOT1289B) plastic SMD package measuring 5.8 × 4.3 × 0.95 mm with 2.13 mm lead pitch and ultra-thin profile optimized for high-density automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary current entry point; electrically tied to Pin 2 for parallel anode connection |
| 2 | Anode | Second anode terminal - dual-anode configuration reduces series resistance and improves current sharing |
| 3 | Cathode | Main current exit and thermal interface; large copper tab provides low Rth(j-sp) = 3 K/W |
Key Features
| Feature | Design Value |
|---|---|
| Very low forward voltage | Typ. 460 mV @ 3 A/25 °C - directly reduces conduction loss and improves system efficiency |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS3L50Q | Same 50 V/3 A rating; VF = 520 mV typ. @ 3 A; TO-277A package (larger footprint, higher Rth(j-a)) | Less suitable for ultra-thin automotive modules due to 1.6 mm height and no AEC-Q101 documentation | Select when board-level thermal relief is available and AEC-Q101 compliance is not required |
| ONsemi NSR3G5002MW | 50 V/3 A; VF = 490 mV typ.; same CFP15B package; AEC-Q101 qualified; slightly higher IR (150 µA) | Compatible drop-in replacement with identical mounting and thermal interface | Prefer when sourcing diversification is needed and 30 µA higher leakage is acceptable |
Compared with STPS3L50Q and NSR3G5002MW, the PMEG050V030EPE-QZ offers the lowest VF (460 mV), best thermal interface (3 K/W Rth(j-sp)), and documented AEC-Q101 qualification - making it optimal for thermally constrained, safety-critical automotive power stages.

FAQ
What is the maximum junction temperature and how does it affect derating?
The PMEG050V030EPE-QZ has a maximum junction temperature of 175 °C. Derating follows Fig. 8 and Fig. 9: at Tamb = 100 °C, IF(AV) drops to ~2.2 A (δ = 0.5) on standard FR4, or ~2.7 A with 1 cm² cathode pad. Exceeding Tj = 175 °C risks permanent parametric shift or failure.
Is the dual-anode configuration internally paralleled or separate terminals?
Pins 1 and 2 are electrically connected anodes - confirmed by the simplified outline and graphic symbol in Table 2. This dual-terminal layout reduces effective series resistance and improves current distribution across the die, supporting the 4.2 A DC rating.
How does the CFP15B package compare thermally to traditional SOD-123 or SMA packages?
CFP15B achieves Rth(j-sp) = 3 K/W via direct clip-bonding to the cathode tab, versus >20 K/W for SOD-123. This enables >2× higher power dissipation at the same board area and eliminates thermal bottlenecks in high-current automotive applications.
Can this diode be used in synchronous rectification topologies?
No - the PMEG050V030EPE-QZ is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier controller. However, its low VF and fast trr make it suitable as the freewheeling diode in quasi-resonant or hard-switched synchronous converters where body diode conduction occurs.
