Cissoid has extended its Planet family of high temperature transistors and switches. Mars is a high temperature 30V small signal P-channel MOSFET transistor suitable for long-term reliable operation from -55°C up to +225°C.
This logic-level P-MOSFET sources up to 310mA at 225°C and can be used to switch medium or high resistances, e.g. to convert a 3.3/5V logic signal to a high voltage open-source output with turn on/off times lower than 10ns. With the gate tied to the source, Mars can also perform as a 30V small current diode for high reliability at high temperature.
Mars complements Mercury –its N-Channel equivalent- for electronic engineers who require reliable, simple discrete analog or digital circuits at high temperature such as pre-regulators, low-dropout regulators, level-shifters, CMOS switches or open source/drain logic on a bus.
Main features: • 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 TO39 metal can package or as bare die
Applications: Sensor interfaces, such as piezoelectric sensor, guard amplifiers, switches of high and medium impedance loads, level-shifters and high temperature diodes
Availability: The product, referenced as CHT-SPMOS30 is now available in TO-39 Metal Can package for sampling and evaluation.
Pricing: Pricing starts at 129 euros ($171) up to 200 units.
