Nexperia USA Inc. PMEG120G20ELRZ

Overview

PMEG120G20ELRZ from Nexperia is a 120 V, 2 A silicon-germanium (SiGe) power rectifier in CFP3 package, designed for high-efficiency DC/DC conversion and output rectification in compact power supplies. It delivers low forward voltage (VF = 0.75 V @ 2 A), fast recovery (trr = 45 ns), and operates up to 175 °C junction temperature - enabling use in automotive infotainment power rails and industrial SMPS secondary-side rectification.

For engineers reviewing the PMEG120G20ELRZ datasheet, PMEG120G20ELRZ pinout, PMEG120G20ELRZ application, or PMEG120G20ELRZ equivalent, key selection criteria include its SiGe process advantage over standard Schottky diodes (higher VRRM with comparable VF), thermal robustness in CFP3, and suitability for space-constrained 12–24 V input systems requiring >90% efficiency at light-to-moderate loads.

Technical Context

This SiGe rectifier uses a monolithic silicon-germanium epitaxial structure to achieve higher reverse breakdown voltage than conventional Schottky diodes while retaining low forward conduction loss. Its 120 V VRRM rating supports 24 V automotive battery systems with margin against load-dump transients.

The device features a single-anode, single-cathode configuration with metal-silicon-germanium barrier formation, enabling fast switching (45 ns trr) without minority-carrier storage delay. Its CFP3 thermally enhanced flat-lead package provides low thermal resistance (Rth(j-l) = 25 K/W) for direct PCB copper pour cooling.

FAQ

Is PMEG120G20ELRZ pin-compatible with standard SOD-123 or SMA packages?

No. PMEG120G20ELRZ uses the CFP3 package (2.5 mm × 2.5 mm, gull-wing leads), which is mechanically and thermally distinct from SOD-123 or SMA. Its thermal pad (Pin 3) requires dedicated PCB land pattern per Nexperia's AN11862 layout guidelines - direct substitution would cause thermal failure and solder joint reliability issues.

Does PMEG120G20ELRZ require a heatsink in typical 2 A operation?

No. At 2 A and 25 °C ambient, with 1 cm² internal copper pour connected to the thermal pad, junction temperature remains below 100 °C. The CFP3 package's 25 K/W Rth(j-l) enables heatsink-free operation in most 24 V industrial and automotive applications - verified per JEDEC JESD51-14 transient thermal simulation.

What is the maximum surge current rating (IFSM) for PMEG120G20ELRZ?

The peak non-repetitive forward surge current (IFSM) is 30 A at 10 ms half-sine wave, per datasheet Figure 6. This rating applies to cold-start inrush or short-duration overload events - sustained current above 2 A must be thermally managed using PCB copper area per the thermal derating curve in Section 6.2 of the official datasheet.

Can PMEG120G20ELRZ replace a 1N5822 in an existing design?

Only with layout revision. While both are 3 A-rated rectifiers, PMEG120G20ELRZ has higher VRRM (120 V vs. 40 V), lower VF (0.75 V vs. 0.9 V), and CFP3 vs. DO-201AD packaging. Direct replacement risks mechanical interference, thermal mismatch, and solder voiding - redesign of footprint, thermal pad, and clearance is mandatory for reliable operation.
