Product details
Overview
PMEG2020EH/6X from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 20 V reverse voltage and 2 A forward current, featuring a very low 450–525 mV forward voltage at 2 A (25 °C, pulsed), housed in an SOD123F surface-mount package. It serves as a low-loss unidirectional power switch in automotive-grade DC-DC converters and polarity protection circuits.
For engineers reviewing the PMEG2020EH/6X datasheet, PMEG2020EH/6X pinout, PMEG2020EH/6X application, or PMEG2020EH/6X equivalent, key selection criteria include its AEC-Q101 qualification, thermal resistance to solder point (150 K/W), low VF performance across temperature, and SOD123F footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to enhance ruggedness against electrical overstress and improve reliability under repetitive surge conditions. Its low forward voltage stems from optimized metal-semiconductor interface design, minimizing conduction losses in low-voltage, high-current paths.
The device operates with junction temperatures up to 150 °C and supports non-repetitive peak forward currents up to 9 A (8 ms, 25 °C initial), making it suitable for transient-heavy automotive subsystems. Thermal resistance from junction to solder point is 150 K/W on standard FR4 with 1 cm² cathode pad - critical for thermal management in compact power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking capability without breakdown; defines use in ≤12 V system rails with margin. |
| Forward Current (IF) | 2 A continuous - Sustained conduction rating at ≤55 °C solder point temperature. |
| Forward Voltage (VF) | 450–525 mV @ 2 A - Directly reduces power loss (≤1.05 W) and heat generation in high-efficiency converters. |
| Reverse Current (IR) | 45–200 µA @ 20 V - Low leakage preserves battery life in always-on automotive modules. |
| Diode Capacitance (Cd) | 50–60 pF @ 5 V - Enables fast switching with minimal AC loss in SMPS output stages. |
| Junction Temperature (Tj) | −65 to +150 °C - Supports operation in under-hood automotive environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive discrete semiconductor stress testing per AEC standard. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; connects to ground or return path; primary thermal interface via exposed cathode pad. |
| 2 | Anode (A) | Positive terminal; receives input voltage; carries forward current into load or converter stage. |
Key Features

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 (550 mV typ @ 2 A), same 20 V VR, SOD-123 package but not AEC-Q101 qualified. | Limited to industrial/commercial use; lacks automotive stress validation. | Select when AEC-Q101 is not required and cost sensitivity outweighs 100 mV VF penalty. |
| SS22H | Same 20 V/2 A rating, VF = 470 mV typ, SOD-123 package, AEC-Q101 qualified, but higher IR (300 µA @ 20 V). | Higher leakage may impact ultra-low-power battery hold-up time. | Prefer where leakage <200 µA is critical, e.g., always-on vehicle telematics modules. |
Compared with RB050M-30 and SS22H, PMEG2020EH/6X delivers the lowest VF (450 mV) among AEC-Q101-qualified 20 V/2 A Schottkys while maintaining the tightest IR spec - optimizing both conduction efficiency and standby integrity in automotive power rails.

FAQ
What is the maximum allowable solder point temperature for PMEG2020EH/6X during reflow?
The device is rated for Tsp ≤ 55 °C continuous operation, but its SOD123F package supports standard lead-free reflow profiles with peak temperatures up to 260 °C for ≤10 seconds. The 55 °C limit applies only to sustained operational solder point temperature - not transient reflow exposure.
Does PMEG2020EH/6X support bidirectional current flow?
No - it is a unidirectional Schottky rectifier. Forward conduction occurs only from anode to cathode; reverse bias blocks current up to 20 V. Its guard ring enhances reverse avalanche capability but does not enable controlled reverse conduction.
How does the SOD123F package compare thermally to SOD-123?
SOD123F has identical footprint dimensions but features flattened leads that improve solder joint reliability and thermal transfer to the PCB. Measured Rth(j-sp) is 150 K/W (vs ~180 K/W for standard SOD-123), enabling ~17% higher power dissipation under identical board conditions.
Is PMEG2020EH/6X suitable for synchronous rectification replacement?
No - it is a passive Schottky diode, not a MOSFET-based synchronous rectifier. While its low VF makes it ideal for asynchronous rectification or OR-ing applications, replacing a synchronous rectifier requires active gate control and is not functionally equivalent.
