Product details
Overview
PMEG2005EH-QX from Nexperia is a 20 V, 0.5 A planar MEGA Schottky barrier rectifier in SOD123F package, featuring 355–390 mV forward voltage at 500 mA, AEC-Q101 qualification, and integrated guard ring for stress protection-used in automotive reverse polarity protection and low-voltage DC-DC converters.
For engineers reviewing the PMEG2005EH-QX datasheet, PMEG2005EH-QX pinout, PMEG2005EH-QX application, or PMEG2005EH-QX equivalent, key selection criteria include ultra-low VF performance, thermal resistance (Rth(j-sp) = 60 K/W), AEC-Q101 compliance, and SOD123F footprint compatibility with space-constrained automotive power rails.
Technical Context
This Schottky rectifier employs a planar MEGA structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress-critical for automotive 12 V system inputs. Its low VF minimizes conduction loss while maintaining low IR (≤200 µA at 20 V) and Cd (66–80 pF at 1 V).
The device operates across −65 °C to +150 °C junction temperature, with pulsed IF capability up to 10 A (8 ms) and continuous IF limited to 0.5 A at Tsp ≤ 55 °C. Thermal design relies on solder-point cooling (Rth(j-sp) = 60 K/W) due to its FR4-mounting-optimized cathode pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 20 V reverse voltage rating-supports full automotive battery transients (ISO 7637-2 Pulse 5a) without breakdown. |
| IF(AV) | 0.5 A average forward current-enables compact, low-loss rectification in 5–12 V auxiliary rails. |
| VF @ 500 mA | 355–390 mV typical-reduces power loss to ≤195 mW at full load, easing thermal management. |
| IR @ 20 V | ≤200 µA reverse leakage-minimizes standby power drain in always-on automotive modules. |
| Cd @ 1 V | 66–80 pF junction capacitance-supports high-frequency switching (>1 MHz) in synchronous buck topologies. |
| Rth(j-sp) | 60 K/W junction-to-solder-point thermal resistance-enables direct thermal coupling to PCB copper for stable operation at 150 °C TJ. |
Pinout & Package
Encapsulated in a 2.6 mm × 1.6 mm × 1.1 mm SOD123F surface-mount plastic package with flat leads and cathode-marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; marked by bar on package body; connects to load ground or return path. |
| 2 | Anode (A) | Input terminal for forward conduction; connects to input rail or switch node; carries full forward current. |
Key Features
| Feature | Design Value |
|---|---|
| Very low VF | 355–390 mV at 500 mA enables ≥95% efficiency in 3.3–5 V buck converter outputs. |
| AEC-Q101 qualified | Stress-tested per automotive discrete semiconductor standard-validates use in engine control, body electronics, and ADAS power stages. |
| Integrated guard ring | Suppresses edge-field concentration to prevent premature avalanche-enhances long-term reliability under repetitive surge conditions. |
| SOD123F package | Small footprint (2.6 × 1.6 mm) with flat leads supports automated placement and reflow, and improves mechanical robustness vs. SOD123. |
Applications
| Automotive Reverse Polarity Protection | Low-Voltage DC-DC Converter Output Rectification |
|---|---|
Use Scenario: Protects infotainment head units and telematics modules from damage during battery jump-start misconnection. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed in series with main 12 V input rail. Use Value: 20 V VR rating withstands load-dump spikes; 390 mV VF limits voltage drop to <0.4 V at 0.5 A, preserving system startup margin. |
Use Scenario: Output rectifier in 5 V/0.5 A buck converter powering MCU core logic in ADAS camera ECU. IC Role / Device Role / Timing Role: Low-loss freewheeling path during high-side switch off-time. Use Value: 66–80 pF capacitance avoids resonance with gate drivers; low VF reduces conduction loss by >40% vs. standard Schottky alternatives. |
| USB-C Power Delivery Input Clamp | Industrial Sensor Node Power Rail Protection |
Use Scenario: Clamps reverse voltage on USB-C VBUS line when connected to legacy 5 V adapters with incorrect polarity detection. IC Role / Device Role / Timing Role: Back-to-back configured as polarity guard before LDO input. Use Value: AEC-Q101 qualification ensures operation over −40 °C to +105 °C ambient; 0.5 A rating supports up to 2.5 W input power. |
Use Scenario: Isolates 3.3 V sensor supply from field-wiring faults in smart building occupancy sensors. IC Role / Device Role / Timing Role: Series protection element between PoE-derived DC-DC output and analog front-end. Use Value: Guard ring prevents failure under induced lightning surges; 200 µA IR at 20 V avoids measurable quiescent current penalty. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (450 mV typ. @ 0.5 A); same 20 V VR; SOD-123 package but no AEC-Q101 qualification. | Limited to industrial/commercial use; not validated for automotive temperature cycling or humidity testing. | Select only if AEC-Q101 is not required and board-level surge immunity is managed externally. |
| SS22 | Lower IF rating (2 A), higher VF (500 mV typ.), larger DO-214AC package; no guard ring or automotive qualification. | Requires more PCB area; unsuitable for space-constrained automotive modules or high-reliability reverse protection. | Prefer for cost-sensitive non-automotive designs where thermal margin exceeds 2× requirement. |
Compared with RB050M-30 and SS22, PMEG2005EH-QX delivers superior thermal performance (60 K/W Rth(j-sp)), guaranteed automotive reliability, and smallest footprint-making it optimal for safety-critical, space-limited 12 V system nodes where VF and qualification are non-negotiable.

FAQ
What is the maximum allowable junction temperature for PMEG2005EH-QX?
The absolute maximum junction temperature is 150 °C, as defined in the limiting values table. Operation at this temperature requires strict thermal design-specifically, mounting on an FR4 PCB with a 1 cm² cathode pad to achieve the rated 60 K/W Rth(j-sp). Continuous operation above 125 °C degrades long-term reliability even within specification limits.
Is PMEG2005EH-QX compatible with lead-free reflow soldering profiles?
Yes-PMEG2005EH-QX is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. The SOD123F package outline and recommended footprint (2.9 mm × 1.6 mm solder land) are explicitly defined in the datasheet for reliable wetting and void-free joints under IPC-A-610 Class 2 conditions.
Does the marking code 'A3' correspond exclusively to PMEG2005EH-QX?
Yes-the marking code 'A3' is assigned solely to PMEG2005EH-QX per Nexperia's official marking table. It appears as a laser-etched alphanumeric identifier on the cathode side of the SOD123F body and is used for traceability in automotive production lots.
Can PMEG2005EH-QX be used in parallel for higher current handling?
No-Schottky diodes exhibit negative temperature coefficient behavior, causing current imbalance when paralleled without external ballasting. The datasheet does not specify matched VF bins or recommend parallel operation. For >0.5 A applications, select a higher-rated part such as PMEG3005EH-QX (30 V, 0.5 A, lower VF) or PMEG6005EH-QX (60 V, 0.5 A).
