Power Semiconductor Devices: Low-Profile LPTO-263

2208p_mv_pc_en.png 2208p_mv_sp_en.png

Introducing Kyocera’s LPTO-263 power semiconductor devices, which have a lower height and higher heat dissipation than existing products (TO-263 package outline).

Features

package outline
  • Low Profile: Approximately 60% lower thickness than the TO-263 package outline.
  • High Heat Dissipation: Chip is connected to the external terminal by a clip to increase the area of the heat sink on the rear.
  • Compatibility: Similar design as the TO-263 package outline.
  • Avalanche-guaranteed SBDs are also available in the lineup.

Size Comparison with the TO-263

By reducing the height, the thickness has been decreased by approximately 60% compared to the TO-263.

Comparison of Heat Generation with the TO-263

In 10A/30V SBD

Heat dissipation has been improved by enlarging the terminal surface and applying internal soldering.

Comparison of heat generation

In 30A/30V SBD

Compared to the TO-263, the temperature rise is reduced by approximately 35 to 50%, and heat dissipation is also improved.
