LS312 SUPER-BETA DUAL NPN TRANSISTOR Linear Systems Offers Direct Alternative for Analog Devices MAT01 The LS312 is a monolithic pair of Super-Beta High Voltage NPN transistors mounted in a single TO-78 package. The monolithic dual chip design reduces parasitics and gives better performance while ensuring extremely tight matching. The LS312 is a direct electrical alternative / equivalent for Analog Devices MAT01. The hermetically sealed TO-78 is well suited for hi-rel and harsh environment applications. (See Packaging Information).
