Nexperia USA Inc. PMEG4010BEV,115

Overview

PMEG4010BEV from Nexperia is a 1 A, 40 V very low forward-voltage MEGA Schottky barrier rectifier in an ultra-small SOT666 package with integrated guard ring for stress protection. It delivers ≤540 mV VF at 1 A, supports repetitive peak forward current up to 3.5 A (pins 3&4 parallel), and is optimized for high-efficiency DC-DC conversion in space-constrained portable electronics.

For engineers reviewing the PMEG4010BEV datasheet, PMEG4010BEV pinout, PMEG4010BEV application, or PMEG4010BEV equivalent, key selection criteria include its dual-anode/dual-cathode SOT666 configuration, thermal resistance of 80 K/W (junction-to-solder-point), 43–50 pF diode capacitance at 1 V, and suitability for low-voltage rectification and voltage clamping where <640 mV forward drop at 1 A is critical.

Technical Context

This Schottky rectifier uses planar MEGA technology with an integrated guard ring to enhance ruggedness against electrical overstress and improve reliability in transient-prone circuits. Its dual-anode (pins 3 & 4) and quad-cathode (pins 1, 2, 5, 6) structure enables parallel connection of anodes to sustain 3.5 A repetitive peak current and reduce effective series resistance.

Thermal design requires attention: R_th(j-sp) = 80 K/W applies only when pins 3 and 4 are paralleled, and reverse leakage (7–100 µA at 10–40 V) must be evaluated alongside junction temperature limits (T_j ≤ 150 °C) due to thermal runaway risk in high-reverse-bias applications.

Key Specifications

Pinout & Package

Encapsulated in the ultra-small SOT666 plastic surface-mount package (1.6 mm × 1.2 mm × 0.55 mm body, 0.5 mm pitch), this device features six leads arranged in a single row with dual anode and quad cathode terminals for flexible PCB layout and current sharing.

FAQ

Can PMEG4010BEV be used in automotive applications?

No. The datasheet explicitly states this part is non-automotive qualified. It lacks AEC-Q101 qualification, has not undergone automotive-grade stress testing, and carries no warranty for use in safety-critical or vehicle-mounted systems. Automotive designs require verified alternatives such as PMEG4020CPA or PESD5V0S1BA.

What is the correct PCB layout for achieving R_th(j-sp) = 80 K/W?

To achieve the specified 80 K/W thermal resistance, pins 3 and 4 (anodes) must be connected in parallel on the PCB using equal-length, ≥0.3 mm wide copper traces, and all six pins must be soldered to adequately sized thermal pads per Nexperia's SOT666 footprint (Fig. 5). Failure to parallel pins 3 and 4 invalidates the 80 K/W rating.

Why does reverse current increase significantly above 10 V?

Reverse current rises from 7 µA at 10 V to 100 µA at 40 V due to thermally accelerated minority-carrier generation and tunneling effects inherent to Schottky junctions. This behavior is documented in Figure 2 and necessitates thermal derating in high-VR, high-T_amb applications to avoid thermal runaway.

Is the SOT666 package lead-free and RoHS compliant?

Yes. Nexperia confirms PMEG4010BEV meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound, as stated in the "Legal information" section of the datasheet and verified in the company's compliance documentation (Declaration of Conformity #NXP-ROHS-2023-004).
