Application Scenarios & Design Considerations

SENSITIVE GATE SCR

Alternative Part Number

  • 2N5060 --: Sensitive-gate SCR in TO-92 with similar gate trigger current and voltage ratings, widely available and a common substitute for small-signal SCRs.
  • C106B --: Sensitive-gate SCR rated for similar blocking voltage and current, suitable for low-power switching applications as an alternative to the STM part.
  • MCR100-6 --: Popular sensitive-gate SCR in TO-92 with comparable gate sensitivity and current capability, often used where small SCRs like the X0203 series are specified.
