Silicon P-N-P Transistors
For Driver and Output Stages in Audio-Amplifier Circuits
Features:
• Planar construction provides low-noise and low·leakage
characteristics
• Gain bandwidth product (fT) = 50 MHz min.
• 40538 is p·n·p complement of 40539' rTh-_-d-'-Yic-"-,-,,-,,,-j-'.-b-',-w-i-Ih-'-i-lh-er-.-,%-...,
• Low saturation voltage: VCE(sat) = -1.1 V max. (40537) = -2.0 V max. (40538)
• High pulse beta at high collector current: hFE = 50 min. at IC = -50 mA (40537)
