Nexperia USA Inc. PMEG045V100EIPE-QZ

Overview

PMEG045V100EIPE-QZ from Nexperia is a 45 V, 10 A planar low forward voltage Schottky barrier rectifier in a CFP15B (SOT1289B) thermally enhanced SMD package. It delivers VF = 490–540 mV at 10 A and 25 °C, supports 210 A non-repetitive peak forward current, is AEC-Q101 qualified, and is used for freewheeling and OR-ing in automotive DC/DC converters.

For engineers reviewing the PMEG045V100EIPE-QZ datasheet, PMEG045V100EIPE-QZ pinout, PMEG045V100EIPE-QZ application, or PMEG045V100EIPE-QZ equivalent, key selection criteria include ultra-low VF at high current, thermal resistance Rth(j-sp) = 3 K/W to cathode solder point, AEC-Q101 qualification, and dual-anode configuration for parallel conduction paths.

Technical Context

This Schottky rectifier uses clip-bond technology to minimize parasitic inductance and enhance thermal transfer from junction to solder point. Its planar structure enables stable reverse recovery (trr = 15 ns ramp, 22 ns step) and low capacitance (Cd = 700 pF at VR = 1 V).

The dual-anode (pins 1 & 2) and single-cathode (pin 3) configuration supports high-current routing with reduced trace resistance and improved current sharing in high-efficiency power stages. Junction temperature is rated up to 175 °C, with derating defined across ambient and solder-point temperatures.

FAQ

What is the maximum junction temperature and how is it enforced?

The absolute maximum junction temperature is 175 °C, verified per IEC 60134 limiting values. Operation above this threshold causes permanent degradation. Thermal design must ensure Tj ≤ 175 °C under worst-case ambient and power dissipation-using Rth(j-sp) = 3 K/W and measured solder-point temperature as the primary thermal boundary condition.

Does the dual-anode configuration require separate PCB traces?

No-pins 1 and 2 are electrically and thermally tied internally as a single anode node. They may be routed to the same net on the PCB; splitting them offers no electrical benefit and risks unbalanced current if trace impedances differ. The dual-pin layout primarily improves mechanical robustness and solder joint reliability.

How does the CFP15B package compare to standard SOD-123 or TO-252 in thermal performance?

CFP15B achieves Rth(j-sp) = 3 K/W-over 15× better than SOD-123FL (~45 K/W) and ~15× better than TO-252 (~45 K/W)-due to its exposed cathode tab directly bonded to PCB copper. This allows >2 W dissipation on a 1 cm² pad, whereas SOD-123 is limited to ~0.3 W and TO-252 to ~1.2 W under identical conditions.

Is the 45 V reverse voltage rating suitable for 24 V automotive systems with load dump?

Yes-the 45 V VR rating complies with ISO 7637-2 Pulse 5a (load dump), which specifies up to 35 V for 12 V systems and up to 60 V for 24 V systems. While marginally below 60 V, PMEG045V100EIPE-QZ is qualified per AEC-Q101 for automotive use and commonly deployed in 24 V systems with clamping or filtering upstream; system-level validation is required for unclamped 60 V transients.
