Product details
Overview
PMEG2005ELD,315 from Nexperia is a 20 V, 0.5 A planar Schottky barrier rectifier in an ultra-small SOD882D leadless package, featuring 450 mV typical forward voltage at 500 mA, 7 ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability-used in low-voltage DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG2005ELD,315 datasheet, PMEG2005ELD,315 pinout, PMEG2005ELD,315 application, or PMEG2005ELD,315 equivalent, key selection criteria include low VF performance under 500 mA load, thermal resistance of 190 K/W on FR4 with 1 cm² cathode pad, ultra-thin 0.37 mm height for space-constrained PCBs, and solderable side pads enabling high-density assembly.
Technical Context
This Schottky rectifier uses a planar MEGA (Maximum Efficiency General Application) structure with integrated guard ring for enhanced ESD and surge robustness. Its low barrier height enables sub-500 mV forward voltage while maintaining <30 μA reverse leakage at 10 V.
The device operates up to 150 °C junction temperature and supports repetitive peak forward current of 2.5 A (tp ≤1 ms). Its 24–30 pF capacitance at 1 V reverse bias and 7 ns trr support ultra-high-speed switching in synchronous buck topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 450 mV typ. at 500 mA - reduces conduction loss in 3.3 V/5 V rail converters |
| Reverse Voltage (VR) | 20 V max - suitable for 12 V automotive and industrial input rails with margin |
| Average Forward Current (IF(AV)) | 0.5 A at Tamb ≤85 °C - defines continuous DC output capability on standard FR4 |
| Reverse Recovery Time (trr) | 7 ns typ. - enables >1 MHz switching without significant switching loss penalty |
| Thermal Resistance (Rth(j-a)) | 190 K/W on FR4, 1 cm² cathode pad - determines derating curve above 85 °C ambient |
| Diode Capacitance (Cd) | 24–30 pF at VR = 1 V - minimizes ringing and EMI in high-frequency SMPS outputs |
| Junction Temperature (Tj) | 150 °C max - allows operation in under-hood automotive environments |
Pinout & Package
Encapsulated in the SOD882D ultra-small leadless plastic package (1.0 × 0.6 × 0.37 mm), this two-terminal device features visible and solderable side pads for automated optical inspection and reliable reflow attachment. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to ground or low-side return path; largest thermal pad for heat dissipation |
| 2 | Anode | Input terminal for forward conduction; routed to supply rail or switch node |
Key Features
| Feature | Design Value |
|---|---|

| Solderable side pads | Supports AOI verification and eliminates tombstoning risk in 0201-class placement |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics applications requiring zero defect rates |
| Ultra-low profile (0.37 mm) | Enables stacking under connectors or in ultra-thin portable power modules |
Applications
| USB Power Delivery Protection | Automotive Body Control Module |
|---|---|
|
Use Scenario: Reverse polarity protection at USB-C port input in portable medical devices. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between input connector and downstream DC-DC converter.

Use Value: <5 μA typical IR at 3.3 V ensures ≤1.5 nA self-discharge current, extending 10-year shelf life target. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-40T1G | 40 V VR, 200 mA IF(AV), VF = 370 mV @ 100 mA - lower current rating, higher voltage margin | Used in 24 V industrial I/O modules where VR margin outweighs current demand | Select when system requires >25 V reverse standoff but can accept 0.2 A average current limit |
| NSR0230HT1G | 30 V VR, 0.2 A IF(AV), VF = 410 mV @ 200 mA - smaller die, lower thermal mass, no AEC-Q101 | Preferred in cost-sensitive consumer wearables lacking automotive qualification requirements | Choose for non-automotive designs prioritizing BOM cost over 150 °C Tj or AEC compliance |
Compared with PMEG2005ELD,315, RB520S-40T1G trades 0.3 A current capacity for +20 V VR headroom, while NSR0230HT1G sacrifices AEC-Q101 and thermal robustness to reduce footprint and unit cost-neither matches its 0.5 A/20 V/AEC-Q101/0.37 mm combination.

FAQ
What is the maximum allowable soldering temperature profile for PMEG2005ELD,315?
Reflow soldering is the only recommended method. Peak temperature must not exceed 260 °C for ≤10 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s. Preheat to 150–200 °C for 60–120 s before reflow, per JEDEC J-STD-020. Wave or hand soldering is not qualified.
Does PMEG2005ELD,315 support bidirectional current flow?
No. It is a unidirectional Schottky rectifier with fixed anode-cathode polarity. Forward conduction occurs only from anode (pin 2) to cathode (pin 1); reverse bias blocks current up to 20 V. The marking bar on the top surface identifies the cathode terminal.
How does the SOD882D package affect thermal performance compared to SOD-123?
SOD882D delivers 30% lower Rth(j-a) than SOD-123 on identical FR4 layouts due to solderable side pads increasing copper contact area. At 0.5 A, junction-to-ambient rise is ~95 °C in SOD882D vs. ~135 °C in SOD-123-enabling higher ambient operation without heatsinking.
Is PMEG2005ELD,315 suitable for use in synchronous rectification circuits?
Yes. With 7 ns trr and low Cd (24–30 pF), it supports gate-drive timing in synchronous buck controllers up to 2 MHz. However, it is a passive rectifier-not a MOSFET-so it replaces the low-side switch only in non-synchronous topologies or as a freewheeling diode alongside active switches.
