Seven power MOSFETs target compact vehicle electronic control units

August 05, 2010 | Paul Buckley | 222901013
Seven power MOSFETs target compact vehicle electronic control units Renesas Electronics has introduced seven new power metal-oxide-semiconductor field-effect-transistor (MOSFET) products equipped in HSON packages for use in automotive electronics control units for applications including direct injection engine management and electric pump motor control.

The new products, including N-channel MOSFETs with voltage ratings of 40 V and 60 V and P-channel MOSFETs with a voltage rating of –30 V, can be used for solenoids and motor switching or to protect against reversed battery conditions.

The new products have the following features:

  • Available in HSON packages that are approximately one-half the size of the existing TO-252 package,
  • Can switch currents up to 75 A DC, and
  • Support channel temperatures up to 175 degrees C. Of note, the NP75N04YUG device features continuous current of 75 A and a low on-resistance maximum rating of 4.8 mΩ, the best-in-class performance among the industry’s existing automotive power MOSFETs in equivalent packages.
The number of vehicle electronic control units increases each year, creating a need to minimize module size and weight while maximizing functionality. Renesas Electronics’ new power MOSFET products were designed specifically to meet the demand for compact, power-dense systems. The newly developed 8-pin HSON package of a quality suitable for use in automotive electrical systems while retaining the same performance as larger TO-252 package MOSFET products.

Key features of the new power MOSFET devices are as follows.

Compact package approximately one-half the size of existing products
  • The newly developed 8-pin HSON package has 48 percent the surface area of the previous TO-252 package. In spite of its compact size, the NP75N04YUG power MOSFET has a low channel-to-case thermal resistance (Note 1) of 1.09 degrees Celsius per watt (degrees C/W). Thus it can handle a maximum continuous power level of 138 W when the case temperature is fixed at 25 degrees C.
