Product details
Overview
PMEG2005AELD from Nexperia is a 20 V, 0.5 A planar Schottky barrier rectifier in an ultra-small SOD882D leadless package, featuring integrated guard ring stress protection, low forward voltage (365–440 mV at 500 mA), 6 ns reverse recovery time, and AEC-Q101 qualification for automotive use in DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG2005AELD datasheet, PMEG2005AELD pinout, PMEG2005AELD application, or PMEG2005AELD equivalent, this device supports high-efficiency low-voltage rectification in space-constrained designs requiring thermal robustness, ultra-fast switching, and solderable side pads on FR4 or ceramic PCBs.
Technical Context
This Schottky diode uses a planar MEGA structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF and ultra-fast trr (6 ns) stem from optimized metal-semiconductor junction design and minimal carrier storage.
Thermal performance is defined by three distinct Rth(j-a) values: 370 K/W (free air), 190 K/W (FR4 with 1 cm² cathode pad), and 125 K/W (Al₂O₃ ceramic), enabling precise thermal modeling across mounting configurations. Junction temperature is rated to 150 °C with ambient operating range from −55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 365–440 mV at 500 mA - enables <150 mW conduction loss in 0.5 A DC-DC output stages |
| Reverse Voltage (VR) | 20 V - suitable for 12 V automotive and 5 V/3.3 V system rail protection |
| Reverse Recovery Time (trr) | 6 ns - minimizes switching losses and EMI in >1 MHz SMPS topologies |
| Diode Capacitance (Cd) | 19–25 pF at 1 V - supports clean high-frequency waveform integrity in signal path clamping |
| Average Forward Current (IF(AV)) | 0.5 A at Tamb ≤85 °C (FR4, 1 cm² cathode pad) - defines continuous power delivery capability in compact layouts |
| Junction Temperature (Tj) | 150 °C max - allows operation in under-hood automotive environments without derating below 85 °C ambient |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Encapsulated in a leadless SOD882D plastic package (1.0 × 0.6 × 0.37 mm), with visible and solderable side pads for reflow-compatible assembly. Cathode identified by marking bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Main current exit terminal; connects to ground or lower-potential rail; largest thermal pad area for heat dissipation |
| 2 | Anode | Main current entry terminal; connects to input or higher-potential rail; smaller pad than cathode |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Prevents edge breakdown under voltage transients, improving long-term reliability in automotive load-dump conditions |
| Solderable side pads | Enables visual inspection and automated optical inspection (AOI) of solder joints without X-ray |
| Ultra-low profile (0.37 mm typ.) | Permits stacking under shields or integration into ultra-thin portable electronics and ADAS modules |
| Low IR (300–600 μA at 10 V) | Reduces standby leakage in always-on battery-powered systems such as telematics and sensor nodes |
| Reflow-only soldering | Eliminates wave soldering compatibility concerns and ensures consistent joint formation in high-volume SMT lines |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Clamp |
|---|---|
Use Scenario: Reverse polarity protection on 12 V supply rail feeding microcontroller and CAN transceiver circuitry. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage during battery jump-start misconnection. Use Value: 440 mV VF limits voltage drop to <0.5 V at 0.5 A, preserving brown-out margin for 5 V LDOs downstream. |
Use Scenario: Low-capacitance clamping diode on USB-C CC line to protect Type-C controller from ESD and overvoltage. IC Role / Device Role / Timing Role: Fast-switching Schottky clamp limiting CC pin voltage to safe levels during hot-plug events. Use Value: 6 ns trr and 25 pF Cd ensure sub-10 ns response without distorting 300 kHz CC signaling waveforms. |
| Industrial IoT Sensor Node | Portable Medical Monitor Power Path |

IC Role / Device Role / Timing Role: Low-loss rectifier converting irregular AC-like harvest output to stable DC bus. Use Value: 365 mV VF at 100 mA enables >85% conversion efficiency even at microwatt input levels. |
Use Scenario: OR-ing diode in dual-battery backup path for ECG front-end analog circuitry. IC Role / Device Role / Timing Role: Ultra-low VF diode ensuring seamless switchover between primary and backup Li-ion cells. Use Value: 0.37 mm height avoids interference with stacked PCB interconnects in handheld form factor. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | 30 V VR, 0.2 A IF(AV), SOD-523 package (1.2 × 0.8 mm), VF = 370 mV @ 100 mA | Higher VR but lower current rating; larger footprint increases board area by 40% | Select when 30 V margin is required and 0.2 A suffices; avoid in 0.5 A automotive loads |
| NSR0230P2T5G | 30 V VR, 0.2 A IF(AV), SOD-923 package (1.0 × 0.6 mm), VF = 450 mV @ 200 mA, no AEC-Q101 | Same footprint but lacks automotive qualification and has higher VF at rated current | Acceptable for consumer wearables; not recommended for automotive or industrial safety-critical paths |
Compared with RB521S-30T2R and NSR0230P2T5G, PMEG2005AELD uniquely delivers 0.5 A current handling in the smallest SOD882D outline while maintaining AEC-Q101 compliance and lowest VF at full rated current-critical for thermally constrained automotive power rails.

FAQ
What is the maximum allowable soldering temperature profile for PMEG2005AELD?
Reflow soldering is the only recommended method. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s, per J-STD-020. Wave soldering is not supported due to package construction and thermal limitations.
Does PMEG2005AELD require derating when mounted on standard FR4 without extended copper pour?
Yes. With no dedicated 1 cm² cathode pad, average forward current drops to 0.25 A at Tamb = 85 °C (per Fig 10). Derating follows linear interpolation: at 25 °C ambient, max IF(AV) = 0.5 A; at 100 °C ambient, max IF(AV) = 0 A - full thermal design requires proper pad layout per datasheet Figure 2.
Can PMEG2005AELD be used in reverse-biased clamping applications above 10 V?
Yes, up to its rated 20 V VR. At VR = 20 V, reverse current is 500–1500 μA (typ./max), which remains acceptable for most clamping functions. However, power dissipation (PR = VR × IR) must be checked: at 20 V and 1500 μA, PR = 30 mW - well within the 340 mW Ptot limit at 25 °C ambient.
How does the integrated guard ring affect layout requirements?
The guard ring eliminates need for extra keep-out clearance around the die edge. Standard SOD882D land pattern (1.4 × 0.8 mm per Fig 17) is sufficient. No additional spacing beyond IPC-7351B recommendations is required - unlike non-guard-ring Schottkys that demand ≥0.1 mm extra margin to prevent surface flashover.
