Product details
Overview
PMEG2020EH 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 typ. 450 mV forward voltage at 2 A and housed in an AEC-Q101-qualified SOD123F package. It serves as a low-loss unidirectional power switch in automotive and industrial DC/DC converters requiring high efficiency and compact footprint.
For engineers reviewing the PMEG2020EH datasheet, PMEG2020EH pinout, PMEG2020EH application, or PMEG2020EH equivalent, key selection criteria include its ultra-low VF (≤525 mV), 150 °C junction temperature rating, AEC-Q101 qualification, and thermal resistance to solder point (150 K/W) - all critical for space-constrained, thermally demanding 12 V/24 V automotive subsystems.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient overvoltage stress. Its low barrier height enables VF as low as 200 mV at 10 mA and 450 mV at 2 A, directly reducing conduction losses in synchronous rectification and reverse polarity protection circuits.
The device operates across –65 °C to 150 °C ambient, with thermal resistance from junction to solder point at 150 K/W on standard FR4 PCB - enabling stable performance in high-density power modules where heatsinking is limited. Reverse leakage remains ≤200 µA at 20 V and 25 °C, supporting low-quiescent-current designs.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB055LAM-40TR | 40 V VR, 5 A IF, VF = 490 mV @ 5 A, SOD-123FL package (longer lead) | Higher voltage margin but larger VF at low current; less suitable for <15 V systems | Choose when 40 V transient immunity is required and board space allows longer lead form factor |
| SS22HE3_A/H | 20 V VR, 2 A IF, VF = 500 mV @ 2 A, AEC-Q101 qualified, SMA package (larger, 4.5 mm × 2.7 mm) | Same electrical specs but 2.5× larger footprint and higher Rth(j-a) (330 K/W) | Use only if existing layout accommodates SMA and thermal budget permits higher junction rise |
Compared with RB055LAM-40TR and SS22HE3_A/H, PMEG2020EH delivers the lowest VF at 2 A in the smallest AEC-Q101-qualified footprint, making it optimal for space- and efficiency-critical 12 V automotive loads where thermal dissipation is constrained.

FAQ
What is the maximum allowable soldering temperature for PMEG2020EH?
The SOD123F package is rated for standard lead-free reflow profiles per JEDEC J-STD-020. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp rates limited to ≤3 °C/s pre-peak and ≤6 °C/s post-peak. Thermal pad design per Figure 5 in the datasheet ensures reliable joint formation without delamination.
Does PMEG2020EH support bidirectional current flow?
No - PMEG2020EH is a unidirectional Schottky rectifier. It conducts only from anode to cathode and blocks current in reverse direction up to 20 V. Bidirectional operation would require a back-to-back diode configuration or a dedicated bidirectional switch IC.
Can PMEG2020EH replace a standard silicon diode in an existing 12 V circuit?
Yes, provided the original diode's VR ≥ 20 V and IF ≥ 2 A. Due to its lower VF, the PMEG2020EH reduces forward drop by ~250–300 mV, lowering power loss and junction temperature. Verify that reverse leakage (≤200 µA) meets system standby requirements before substitution.
Is the marking code 'A6' sufficient for full traceability?
Yes - 'A6' is the official Nexperia top-side marking for PMEG2020EH per Table 4. When combined with reel labeling (including date code, lot number, and Nexperia logo), it provides full traceability to wafer lot and assembly batch per IATF 16949 requirements.
