The MAT03 dual monolithic PNP transistor offers excellent parametric matching and high frequency performance. Low noise characteristics （1 nV/√Hz max @ 1 kHz）， high bandwidth （190 MHz typical）， and low offset voltage （100 μV max）， makes the MAT03 an excellent choice for demanding preamplifier applications. Tight current gain matching （3% max mismatch） and high current gain （100 min）， over a wide range of collector current， makes the MAT03 an excellent choice for current mirrors. A low value of bulk resistance （typically 0.3 ?） also makes the MAT03 an ideal component for applications requiring accurate logarithmic conformance. Each transistor is individually tested to data sheet specifications. Device performance is guaranteed at 25°C and over the extended industrial and military temperature ranges. To ensure the longterm stability of the matching parameters， internal protection diodes across the base-emitter junction clamp any reverse baseemitter junction potential. This prevents a base-emitter breakdown condition that can result in degradation of gain and matching performance due to excessive breakdown current.
