Applications

  • Automotive relay driver
  • LED string drive transistor
  • High-voltage level shifting
  • Industrial control switching

The MMBTA42Q-7-F from Diodes Inc is an AEC-Q101 automotive NPN high-voltage transistor rated 300V VCEO and 500mA IC in SOT-23 package. The 300V rating suits relay driving, high-voltage level shifting, and LED string driving in automotive and industrial applications. hFE of 30-40 provides adequate gain for saturated switching with moderate base drive.

Standard planar NPN epitaxial structure. The high-voltage collector design uses a lightly-doped collector drift region to support 300V without avalanche breakdown. Base drive current (IB) controls collector current (IC = hFE * IB). For saturated switching, IB must exceed IC/hFE(sat) to ensure VCE(sat) < 0.9V.
