MMBT5551

Transistors - Bipolar (BJT) - Single

NPNHigh VoltageSOT-23BJT

The MMBT5551 is a high-voltage NPN transistor in an SOT-23 package, ideal for medium-power switching and amplification.

Best for

  • High-voltage switching
  • Medium-power amplification

Avoid if

  • Applications requiring very high current (>600mA) or low-voltage logic levels where a standard small-signal transistor suffices.

Check before use

  • Thermal dissipation limits
  • hFE classification (L: 100-200, H: 200-300)
