BT168GW,135

Scrs Overview

The BT168GW,135 is a planar passivated silicon controlled rectifier (SCR) featuring a sensitive gate structure, housed in a SOT223 surface-mountable plastic package. Designed for direct interfacing with microcontrollers and logic integrated circuits, it supports low power gate trigger applications. Key electrical parameters include a repetitive peak reverse voltage of 600 V, an average on-state current of 0.63 A, and an RMS on-state current of 1 A. The device withstands a surge current of 8 A, requires a maximum gate trigger current of 0.2 mA, and offers a high dV/dt rating of 500 V/µs. It operates within an industrial qualification range with a maximum junction temperature of 125°C.

Scrs Feature Summary

• Sensitive gate design enables direct interface with microcontrollers and logic ICs without additional drive circuitry.
• Planar passivated SCR construction provides robust performance and reliability in surface-mount applications.
• High dV/dt capability ensures stable operation against rapid voltage transients in switching environments.

Scrs Applications

• Direct interfacing with microcontrollers for low-power switching control
• Logic integrated circuit output stages requiring isolated triggering
• Low power gate trigger circuits in industrial automation

Scrs Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration. The BT168GW,135 designation corresponds to a 13-inch reel packing format. Confirm RoHS compliance and lead-free status through official manufacturer documentation or authorized distributor datasheets before procurement integration.

Scrs Selection Notes

Select this component when a surface-mount SCR with sensitive gate characteristics is required for logic-level interfacing. Ensure the application demands do not exceed the 600 V blocking voltage or 0.63 A average current limits. Consider the SOT223 package constraints for thermal management and PCB layout requirements relative to the 125°C maximum junction temperature specification.
