Enables power supply designs that are smaller and more reliable than conventional products! SiC MOSFET "NTBL045N065SC1"

Introduction

TO-Leadless (TOLL) package 650V of SiC MOSFET"NTBL045N065SC1 "of 3 Here are some features.

・Reduced package size
・Low noise and reduced switching loss
・High reliability

Details are introduced below.

Miniaturization of package size

The package dimensions of the NTBL045N065SC1 are 9.90 x 11.68mm with a height of 2.30mm. Compared to the general D2PAK package, the printed circuit board mounting area can be reduced by 30 %. In addition, since the height is also reduced, the volume can be reduced by as much as 60 %.

Low noise and reduced switching loss

NTBL045N065SC1 is V _DSS Rated 650V, R _DS_(on) standard value of 33 mΩ, maximum drain current (I _D.)teeth 73A is. Maximum operating temperature 175℃, Q _G._(TOT) But 105 nC This extremely low gate charge greatly reduces switching losses. Also the package inductance 2nH and low.

In addition, the Kelvin source configuration enables reduction of gate noise and switching loss, resulting in lower turn-on loss (E _ON)of 60 % is also reduced.

The figure below shows the turn-on loss and turn-off loss, TO-247-3L package and TOLL This is a graph comparing packages.

The figure below shows the waveforms at turn-on and turn-off. The colored line is the TOLL package waveform, and the white line is the TO-247-3L package waveform.

From the waveforms below, it can be seen that the turn-on loss (E _ON) has decreased and the ringing of the gate has decreased.

The pinout for the Kelvin source configuration is shown below.

high reliability

The TOLL package complies with the MSL1 (Moisture Sensitivity Level 1) standard, which reduces the failure rate during mass production. In addition, the thermal resistance value R_{θ jc} is as low as 0.35 to 0.5 °C /W, so excellent thermal characteristics can be demonstrated.

The NTBL045N065SC1 can be considered in demanding applications such as switch mode power supplies (SMPS), server and telecom power supplies, solar inverters, uninterruptible power supplies (UPS) and energy storage.
