MMBTA44 product

MMBTA44

Transistors - Bipolar (BJT) - Single

NPNHigh VoltageSOT-23

The MMBTA44 is a high-voltage NPN transistor designed for applications requiring up to 400V collector-emitter breakdown voltage in a compact SOT-23 surface-mount package.

Best for

  • High voltage switching
  • General purpose amplification

Avoid if

  • Applications requiring high current (>200mA)
  • Extremely space-constrained designs where thermal management is impossible

Check before use

  • Thermal dissipation limits
  • PCB creepage and clearance for 400V
