• High static dv/dt capability for noise immunity
• Small die planar construction for fast turn-off time

Scrs Applications

• Phase control circuits
• General purpose switching applications
• Electronic circuits requiring thyristor-based regulation

Scrs Procurement Notes

Verify the specific suffix AP against the manufacturer datasheet to confirm pinout and packaging variations. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the Littelfuse part number with distributor catalogs to confirm availability status and lead times prior to ordering.

Scrs Selection Notes

Select this component when a 600V blocking voltage and 1.5A continuous current rating are required in a compact TO-92 package. The sensitive gate characteristics suit applications demanding minimal gate drive current. Verify thermal management capabilities for the intended operating environment within the specified -40°C to +125°C range.

Scrs Part Context

This part belongs to the Sx02xS series of low power SCRs from Littelfuse. The series offers high static dv/dt and low turn-off times through small die planar construction. These devices are designed for general-purpose switching and phase control applications where compact size and reliable performance are essential.

Scrs Replacement Considerations

Direct substitutes may include other 600V, 1.5A SCRs in TO-92 packages from manufacturers such as STMicroelectronics or Vishay. Verify equivalent gate trigger currents and holding currents to ensure circuit compatibility before substitution.
