Product details
Overview
PMEG2005CT from Nexperia is a dual common-cathode Schottky barrier rectifier in SOT23 package, designed for low-voltage, high-efficiency DC/DC conversion and reverse polarity protection. It delivers 500 mA average forward current per diode, 20 V reverse voltage rating, and ultra-low 360–390 mV forward voltage at 0.5 A and 25 °C - enabling reduced conduction loss in compact power rails.
For engineers reviewing the PMEG2005CT datasheet, PMEG2005CT pinout, PMEG2005CT application, or PMEG2005CT equivalent, key selection criteria include its dual-diode common-cathode topology, thermal performance on FR4 vs. ceramic PCBs, reverse recovery time of 22 ns, and compatibility with space-constrained SMPS designs requiring <1 mm height.
Technical Context
This device integrates two planar Schottky diodes sharing a single cathode terminal (Pin 3), with guard ring stress protection to enhance reliability under transient overvoltage. Its low VF stems from optimized metal-semiconductor junction design, not silicon PN structure.
Thermal behavior is highly dependent on PCB mounting: Rth(j-a) ranges from 270 K/W (ceramic) to 375 K/W (standard FR4), and maximum junction temperature is rated at 150 °C. Repetitive peak forward current reaches 3.9 A (tp ≤ 1 ms), supporting pulsed load handling in synchronous rectification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - defines maximum blocking capability per diode in reverse bias; sets upper limit for input voltage in buck converters or reverse protection circuits. |
| Average Forward Current (IF(AV)) | 0.5 A per diode - continuous DC or square-wave current capacity at Tsp ≤ 130 °C on FR4; determines usable output current in low-power SMPS outputs. |
| Forward Voltage (VF) | 360–390 mV at IF = 0.5 A, Tj = 25 °C - directly reduces conduction loss and heat generation compared to standard silicon diodes (~700–1000 mV). |
| Reverse Recovery Time (trr) | 22 ns - enables efficient high-frequency switching (>1 MHz) without significant switching loss or ringing in fast-switching topologies. |
| Reverse Current (IR) | 30–200 µA at VR = 20 V, Tj = 25 °C - low leakage preserves efficiency in battery-powered systems during standby or light-load conditions. |
| Diode Capacitance (Cd) | 66–80 pF at VR = 1 V, f = 1 MHz - limits high-frequency noise coupling and affects EMI filter design in sensitive RF or audio supply rails. |
| Junction Temperature (Tj) | 150 °C maximum - constrains thermal design margin; requires attention to solder-point thermal resistance (Rth(j-sp) = 60 K/W) for reliable long-term operation. |
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 PMEG2005CT uses a 3-terminal common-cathode configuration optimized for minimal board area and thermal path efficiency.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input/output node for first Schottky diode; connects to source-side of rectification path (e.g., switch node in buck converter). |
| 2 | Anode (Diode 2) | Independent anode for second diode; supports dual-rail or redundancy configurations without shared anode parasitics. |
| 3 | Common Cathode (K1/K2) | Shared cathode terminal for both diodes; serves as low-impedance return path and primary thermal interface to PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-cathode topology | Enables independent anode routing while minimizing cathode loop inductance - critical for reducing voltage spikes in high-dI/dt SMPS applications. |
| Guard ring stress protection | Improves ruggedness against ESD and transient overvoltage events without sacrificing low VF, extending field reliability in unregulated input environments. |
| Low thermal resistance to solder point | Rth(j-sp) = 60 K/W - allows direct thermal coupling from junction to PCB copper, supporting higher sustained current on thermally optimized layouts. |
| Ultra-fast reverse recovery | trr = 22 ns - eliminates minority-carrier storage delay, enabling clean turn-off in synchronous rectifier or OR-ing applications up to 2 MHz. |
| Small footprint & low profile | SOT23 package (1.0 mm max height) - fits under low-clearance shields and enables dense layout in portable electronics and wearables. |
Applications
| USB Power Delivery Input Protection | Secondary-Side Rectification in Buck Converters |
|---|---|
|
Use Scenario: Protecting 5 V/9 V/15 V USB PD input rails from reverse connection or backfeed during multi-source negotiation. IC Role / Device Role / Timing Role: Dual-anode configuration allows separate upstream/downstream polarity enforcement; common cathode simplifies ground-referenced sensing. Use Value: 360 mV VF minimizes voltage drop across protection path, preserving >98% of input voltage margin for downstream regulation. |
Use Scenario: Output rectification in 3.3 V/1.8 V buck converters operating at 500 kHz–2 MHz switching frequency. IC Role / Device Role / Timing Role: Schottky diode replacing synchronous MOSFET gate driver complexity; 22 ns trr ensures minimal dead-time loss. Use Value: Low Cd (66–80 pF) reduces high-frequency capacitive loading on switch node, improving EMI signature and stability. |
| Redundant Power OR-ing | Low-Power IoT Sensor Rail Protection |
|
Use Scenario: Combining two independent 3.3 V LDO outputs (e.g., main + backup battery) into a single system rail with automatic failover. IC Role / Device Role / Timing Role: Each anode accepts one supply; common cathode feeds load - provides passive, zero-latency OR-ing without control IC. Use Value: 0.5 A per diode rating supports typical sensor node loads (≤300 mA); 30 µA IR at 25 °C prevents excessive standby drain. |
Use Scenario: Reverse polarity and overvoltage clamp for coin-cell–powered BLE/Wi-Fi modules with tight space constraints. IC Role / Device Role / Timing Role: Placed inline between battery connector and PMIC input; guards against accidental reverse insertion or charger misconnection. Use Value: SOT23 footprint fits within 2.5 mm × 1.5 mm keep-out zone; 20 V VR safely clamps 12 V adapter surges without breakdown. |
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 | Single-diode SOD-323 package; 30 V VR, 500 mA IF(AV), VF ≈ 450 mV @ 0.5 A | Lacks dual-anode flexibility; no common-cathode advantage for OR-ing or dual-rail use | Choose only when single-diode function suffices and board space permits larger SOD-323 footprint. |
| SS24 | Single-diode SMA package; 40 V VR, 2 A IF(AV), VF ≈ 500 mV @ 2 A - higher VF, larger size, no dual configuration | Not pin-compatible; unsuitable for space-constrained dual-path designs due to discrete packaging | Select only for higher-current, lower-frequency applications where thermal mass outweighs VF penalty. |
Compared with RB050M-30 and SS24, the PMEG2005CT uniquely combines dual-anode routing, SOT23 miniaturization, and sub-400 mV VF - making it optimal for compact, multi-rail, high-frequency DC/DC where layout density and conduction loss are co-critical.

FAQ
What is the maximum ambient temperature for continuous 0.5 A operation on standard FR4?
At δ = 0.5 and f = 20 kHz, the PMEG2005CT supports 0.5 A average forward current up to 100 °C ambient temperature when mounted on standard FR4 PCB (Fig. 9). Above this, derating is required to maintain Tj ≤ 150 °C - e.g., 0.35 A at 125 °C ambient.
Can Pin 1 and Pin 2 be used for different voltage rails simultaneously?
Yes - Pins 1 and 2 are electrically isolated anodes, each forming a separate Schottky diode with the common cathode (Pin 3). This enables true dual-rail operation, such as independent 3.3 V and 5 V OR-ing or separate reverse protection paths without cross-talk.
Is the PMEG2005CT automotive qualified?
No - the latest revision (v.4, October 2024) explicitly states "non-automotive qualification" in the revision history. For automotive applications, Nexperia offers Q-grade alternatives (e.g., PMEG2005CT-Q), which undergo AEC-Q101 testing and have different qualification documentation.
How does the guard ring affect layout or PCB design?
The integrated guard ring improves voltage standoff and ESD robustness but does not require special layout rules. However, maintaining recommended solder pad dimensions (Fig. 16/17) and avoiding solder mask over the cathode pad (Pin 3) is essential to preserve its thermal and electrical performance as specified in the datasheet.
