30V small signal PMOS

The CHT-MARS is a high voltage 30V P-channel small-signal MOSFET designed to achieve high performance in an extremely wide temperature range: typical operation temperature goes from -55°C to 225°C.

Typical performances:

  • Temperature range: -55°C to +225°C
  • Drain voltage up to -30V
  • Max 310mA  drain current @ 225°C
  • Vgs=0V to -5V
  • Input capacitance: 14pF
  • Gate Leakage: 0.4µA @ 225°C 
  • Available in TO18 metal can package



  • Sensor interfaces, such as piezoelectric sensors
  • Guard amplifiers
  • Switches of high and medium impedance loads
  • Level shifters
