Product details
Overview
PMEG4005CT,215 from Nexperia is a dual common-cathode Schottky barrier rectifier in SOT23 package, rated for 40 V reverse voltage and 500 mA average forward current per diode, with typical forward voltage of 410–470 mV at 500 mA and reverse leakage under 100 µA at 40 V. It serves as a low-loss rectification and polarity protection device in compact DC/DC converters and SMPS outputs.
For engineers reviewing the PMEG4005CT,215 datasheet, PMEG4005CT,215 pinout, PMEG4005CT,215 application, or PMEG4005CT,215 equivalent, key selection criteria include low VF performance at 500 mA, thermal derating on FR4 PCBs, dual-diode common-cathode topology, and SOT23 footprint compatibility with high-density layouts.
Technical Context
This dual Schottky rectifier uses planar die construction with integrated guard ring for ESD and transient stress protection. Its common-cathode configuration enables shared cathode routing in dual-rail or redundancy applications while maintaining independent anode control.
The device exhibits ultrafast reverse recovery (trr ≤ 13 ns) and low junction capacitance (Cd = 43–50 pF), supporting high-frequency switching up to several MHz. Thermal resistance varies significantly with PCB layout: Rth(j-a) ranges from 270 K/W (ceramic) to 375 K/W (standard FR4), directly impacting power handling at elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 40 V - Maximum blocking voltage before breakdown; defines usable input range in 3.3 V/5 V/12 V rail protection and buck converter freewheeling. |
| IF(AV) (Avg. Forward Current) | 0.5 A per diode - Sustained DC or square-wave current capability at Tsp ≤ 130 °C; supports continuous 500 mA loads in space-constrained designs. |
| VF (Forward Voltage) | 410–470 mV @ 500 mA, 25 °C - Low conduction loss enabling >95% efficiency in low-voltage (<5 V) DC/DC stages and battery-powered systems. |
| IR (Reverse Leakage) | 27–100 µA @ 40 V, 25 °C - Minimal standby power loss; critical for reverse polarity protection in always-on IoT nodes and energy-harvesting circuits. |
| trr (Reverse Recovery Time) | ≤13 ns - Enables clean turn-off in high-frequency (>1 MHz) switching topologies without tail current or cross-conduction risk. |
| Cd (Diode Capacitance) | 43–50 pF @ 1 V, 1 MHz - Low capacitive loading preserves signal integrity in fast-switching gate drive paths and RF-adjacent power rails. |
Pinout & Package
Encapsulated in a standard SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch), the PMEG4005CT,215 features three terminals optimized for automated assembly and thermal management on FR4 or ceramic PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input terminal for first Schottky diode; connects to positive source in dual-rail rectification or isolated output path. |
| 2 | Anode (Diode 2) | Independent input terminal for second diode; enables OR-ing, redundancy, or dual-output freewheeling without shared anode impedance. |
| 3 | Common Cathode (K1/K2) | Shared output node; simplifies PCB routing and thermal coupling; requires adequate copper area (≥1 cm² recommended on FR4) for 460 mW total dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF Schottky architecture | 410–470 mV @ 500 mA reduces conduction loss by ≥30% vs. standard silicon diodes, directly improving light-load efficiency in portable devices. |
| Integrated guard ring | Enhances ruggedness against ESD and voltage transients (IEC 61000-4-2 Level 4), eliminating need for external TVS in cost-sensitive consumer power rails. |
| Common-cathode dual-diode topology | Enables compact OR-ing of two power sources (e.g., battery + USB) or dual-output buck converter freewheeling with single thermal pad. |
| SOT23 footprint compatibility | Matches industry-standard pick-and-place tooling and reflow profiles; supports 0.6 mm solder paste stencil apertures per IPC-7351B. |
Applications
| USB Power Path Management | Battery Backup OR-ing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (520 mV typ @ 500 mA); TO-236AB (SOT-23 variant) with identical pinout but larger thermal pad. | Lower efficiency in battery-fed apps; better thermal margin on FR4 due to larger exposed cathode area. | Choose when board-level thermal resistance exceeds 310 K/W and 460 mW dissipation must be sustained at Tamb = 85 °C. |
| SS34-E3/57T | Single-diode SMC package (3.7 mm × 2.7 mm); 40 V VR, 3 A IF(AV), VF = 500 mV @ 3 A. | Not pin-compatible; requires redesign for dual-path use; higher current rating suits higher-power SMPS outputs. | Choose only when scaling to >1 A per path and SOT23 size constraint is relaxed; not suitable for OR-ing or space-limited layouts. |
Compared with RB050M-30 and SS34-E3/57T, the PMEG4005CT,215 delivers the lowest VF in SOT23 form factor, enabling highest efficiency in miniaturized dual-rail systems, while its guard ring and 13 ns trr provide superior transient immunity and high-frequency suitability unmatched by alternatives.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature (Tj) is 150 °C per the datasheet limiting values. For reliable long-term operation, design should maintain Tj ≤ 130 °C under worst-case conditions-achievable with ≤0.5 A average current on FR4 PCBs with 1 cm² cathode copper, or ≤0.75 A on ceramic substrates. Thermal simulation using Rth(j-sp) = 60 K/W is recommended for precision thermal modeling.
Can PMEG4005CT,215 be used in automotive applications?
No-this part is explicitly marked non-automotive qualified per the 2024 revision history. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation. For automotive use, Nexperia offers the PMEG4005CT-Q series with full AEC-Q101 compliance, enhanced HTOL testing, and guaranteed operation from −40 °C to +150 °C.
How does the common-cathode configuration affect PCB layout?
The shared cathode (Pin 3) must be routed to a single low-impedance ground or output net with sufficient copper area-minimum 1 cm² on FR4 for full 460 mW dissipation. Splitting cathode traces or using narrow traces increases thermal resistance and risks localized overheating. Thermal vias under Pin 3 are strongly recommended for high-reliability designs.
Is the 13 ns trr value guaranteed across temperature and voltage?
Yes-the 13 ns maximum trr is specified under standardized test conditions (IF = 10 mA, IR = 10 mA, IR(meas) = 1 mA, RL = 100 Ω, Tj = 25 °C). At elevated temperatures (e.g., 125 °C), trr increases to ~18 ns; at lower currents (<1 mA), it drops below 10 ns. The value remains valid for VR ≤ 40 V and is unaffected by forward voltage swing.
