BTS50015-1TAD - Power PROFET™

The BTS50015-1TAD is the lead product of an ultra-low ohmic protected high-side switch family (1.0mΩ to 2.5mΩ) based on a new technology offering the benchmark current & energy capabilities to drive applications from 20A up to 40A DC. 
The Power PROFET™ are especially designed to replace high current relays and fuses in a wide range of applications such as power distribution (e.g. module main switches and trailer node supply), heating (e.g. PTC heaters and rear defoggers) or application with high switching cycles and energy requirements (Vacuum pump, Fan, Starter relay, …)


  • High Side Switch embedded with diagnostic and protection functions 
  • Ultra-low RDS_ON to drive applications up to 35A DC. 
  • Inrush current up to 135A 
  • Load current sensing 
  • Benchmark energy capability (EAS=3000mJ, EAR=550mJ @ Inom) 
  • Outstanding short circuit performance (Grade A by AEC-Q100) 
  • Operating voltage range: 8V to 18V 
  • 3.3V to Vs compatible logic inputs 
  • Very low leakage current at OUT pin 
  • Optimized EMC behaviour


  • Turn-key solution reducing time to market. 
  • Reduce power losses up to factor 7 compared to relays 
  • Save cost on system level by removing the need for freewheeling diode for many applications 
  • Improved load monitoring and protection with current sense 
  • Resettable device with benchmark short-circuit performance : no maintenance required

Target Applications

  • Suitable for resistive, inductive and capacitive loads 
  • Replaces electromechanical relays, fuses and discrete circuits 
  • Most suitable for applications with high current loads, such as heating system, main switch for power distribution, start-stop power supply switch 
  • PWM applications with low frequencies

Application Examples

  • Smart power distribution 
  • Heating applications: PTC heater, rear defogger, wind-shield de-icer 
  • Electric break vacuum pump, starter relay
