Product details
Overview
PMEG2010AEBF from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 20 V reverse voltage and 1 A forward current, featuring ultra-low forward voltage (510–620 mV @ 1 A) in an SOD523 (SC-79) package. It serves as a low-loss unidirectional switch in compact DC/DC converters and polarity protection circuits.
For engineers reviewing the PMEG2010AEBF datasheet, PMEG2010AEBF pinout, PMEG2010AEBF application, or PMEG2010AEBF equivalent, key selection criteria include its 1 A continuous forward rating at ≤55 °C solder point temperature, 20 V blocking capability, 19–25 pF junction capacitance at 1 V, thermal resistance of 75 K/W (junction-to-solder point), and cathode/anode pin configuration in ultra-small SMD form.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF stems from optimized metal-semiconductor interface design, enabling high conduction efficiency without PN-junction recovery losses.
Thermal performance is defined relative to solder point (Rth(j-sp) = 75 K/W), not ambient, due to self-heating sensitivity in Schottky devices; reverse leakage (0.32–1.5 mA @ 20 V) and capacitance (19–25 pF @ 1 V, 1 MHz) are characterized under pulsed conditions to minimize self-heating effects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum DC or repetitive peak reverse bias before breakdown; defines safe operating range in clamping and reverse-polarity protection. |
| Forward Voltage (VF) | 510–620 mV @ 1 A, 25 °C - Directly determines conduction loss (0.51–0.62 W) in high-efficiency 1 A power paths. |
| Forward Current (IF) | 1 A continuous @ Tsp ≤ 55 °C - Thermal limit tied to solder point temperature, not ambient; requires PCB copper thermal relief design. |
| Junction Capacitance (Cd) | 19–25 pF @ 1 V, 1 MHz - Sets high-frequency switching node impedance; critical for EMI and snubberless flyback or buck converter operation. |
| Reverse Leakage (IR) | 0.32–1.5 mA @ 20 V, 25 °C - Dominates standby power loss in low-power systems; increases significantly above 85 °C. |
| Thermal Resistance (Rth(j-sp)) | 75 K/W - Junction-to-cathode-tab solder point; enables thermal modeling using PCB pad as heat sink, not ambient air. |
Pinout & Package
The PMEG2010AEBF is housed in an SOD523 (SC-79) surface-mount plastic package measuring 1.2 mm × 0.8 mm × 0.6 mm, with gull-wing leads and cathode tab solder point for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to internal N-type semiconductor; primary heat path to PCB via cathode tab; must be routed to thermal pad for rated 1 A operation. |
| 2 | Anode (A) | Connected to platinum-silicide Schottky contact; carries full forward current; no thermal sinking function. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge electric field concentration, improving VR consistency and surge robustness without derating. |
| Ultra-low VF at 1 A | Reduces conduction loss by ≥30 % vs. comparable 20 V Schottkys, directly extending battery life in portable 3.3 V/5 V rails. |
| SOD523 footprint | Enables placement in <1.5 mm² board area-critical for wearables, hearing aids, and space-constrained IoT sensors. |
| 150 °C max junction temperature | Allows operation in sealed enclosures up to 85 °C ambient when thermally anchored via cathode pad. |
Applications

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, 200 mA IF, 370 mV VF @ 100 mA; SOD-523 package | Lower current rating limits use to sub-200 mA rails; better VF at light load | Select when system operates below 200 mA and requires tighter VF control at microampere loads. |
| NSR0230HT1G | 30 V VR, 200 mA IF, 450 mV VF @ 100 mA; SOD-123 package (larger) | Larger SOD-123 footprint increases board area by 3×; higher thermal mass improves pulse handling | Choose where board space allows and repetitive 3.5 A peak current (IFRM) is required over continuous 1 A. |
Compared with RB521S-30T2R and NSR0230HT1G, the PMEG2010AEBF uniquely supports 1 A continuous conduction in SOD523 while maintaining <620 mV forward drop-enabling miniaturized, high-current 3.3 V/5 V power rails where thermal anchoring to cathode pad is feasible.

FAQ
What is the maximum continuous forward current for PMEG2010AEBF?
The PMEG2010AEBF supports 1 A continuous forward current only when the solder point temperature (Tsp) is maintained at or below 55 °C. This is not an ambient temperature rating-it requires direct thermal coupling of the cathode pad to PCB copper, verified via thermal simulation or IR measurement under real operating conditions.
Does PMEG2010AEBF have automotive qualification?
No, the PMEG2010AEBF is not AEC-Q200 qualified or specified for automotive use. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products like this device are unsuitable for safety-critical or life-support systems, and inclusion in such applications is solely at the customer's risk.
How does the guard ring improve reliability?
The integrated guard ring redistributes electric field lines away from the semiconductor edge, preventing premature avalanche breakdown under voltage transients or mechanical stress. This allows consistent 20 V reverse blocking performance even after repeated thermal cycling or board flex-critical for wearable and medical patch applications.
Can PMEG2010AEBF replace a standard PN diode in a 5 V rail?
Yes-its 510–620 mV forward voltage reduces conduction loss by ~65 % versus a typical 1 A silicon PN diode (~1.1 V VF). However, reverse leakage (up to 1.5 mA at 20 V) is higher than PN diodes, so verify standby current budgets in always-on systems before substitution.
