New Product Introduction

Infineon OptiMOS™ 5 80 V/100 V automotive MOSFET

OptiMOS™ 5 80 V/100 V automotive MOSFET in SSO8 and S3O8 packages for 48 V applications

Infineon Technologies OptiMOSTM-5 80 V100 V product image

Infineon is extending its product family of 80 V and 100 V MOSFETs based on OptiMOS™-5 Silicon technology. The MOSFET family is offered in the SSO8 package with its 5x6 mm² footprint for medium power and the smaller S3O8 for lower power applications, such as 48 V auxiliaries, but also automotive LED lighting. The new MOSFETs have tightened VGS thresholds in order to support designs with parallel MOSFETs, providing a very low system level RDS(ON). Next to the low RDS(ON) types, a broad selection of 80 V and 100 V MOSFETs with higher RDS(ON) is on offer.


Key features

  • RDS(ON) down to 3.1 mΩ (80 V) and 4.0 mΩ (100 V) in SSO8 package
  • Higher RDS(ON) variants in 80 V and 100 V in small S3O8 package
  • Reduced conduction losses
  • Optimized switching performance


Additional features

  • Reduced form factor compared to traditional SMD packages



  • 48 V Application
  • Battery Management and Power Distribution
  • E-booster, E-compressor and E-suspension
  • Auxiliaries


Available tools
