Infineon Multiplexer CMOS Surface Mount 5-Pin TO-263 Package, 4.75-41V, Low On-State Resistance BTS441TGATMA1

Infineon BTS441TGATMA1 is a multiplexer CMOS device featuring a 5-pin TO-263 surface mount package designed for efficient power and signal routing in electronic systems. It operates reliably across a minimum supply voltage of 4.75V to a maximum of 41V, making it suitable for various applications requiring wide voltage range compatibility. The device exhibits a low on-state resistance of 20 milliohms, minimizing conduction losses and enhancing energy efficiency.

Designed for harsh conditions, the device supports operation within an ambient temperature range from -40°C up to 150°C, enabling deployment in automotive and industrial environments. Its CMOS output type ensures low quiescent switching currents for reduced power consumption. The TO-263 package includes a thermal pad and necessitates proper soldering fillets for heat dissipation and mechanical stability.

Typical applications include multiplexing automotive power rails, high-current load switching in power distribution systems, and battery management systems requiring low-loss switches. This multiplexer is also ideal for compact surface-mount power selectors on printed circuit boards and is suitable for industrial control assemblies operating across wide voltage ranges.

PCB designers should consider thermal via implementations and adequate copper areas to ensure effective heat spread and maintain junction temperature within operating limits. The device provides a reliable solution where controlled signal or power routing with low resistance and compact form factor is essential.
