CZS5064 TR PBFREE

Overview

The CMPS5064 is a silicon controlled rectifier (SCR) manufactured by Central Semiconductor Corp, designed for surface-mount applications in the SOT-23 package. It features a 400 V off-state voltage rating and supports a maximum average on-state current of 160 mA with an RMS current capacity of 250 mA. The device utilizes a sensitive gate structure, requiring a maximum gate trigger voltage of 800 mV and a gate trigger current of 200 µA to initiate conduction. In the on-state, it exhibits a maximum voltage drop of 1.7 V. The component operates within a junction temperature range of -65°C to 125°C and maintains a maximum off-state leakage current of 1 µA.

Feature Summary

• Sensitive gate architecture enables reliable triggering with low control power requirements.
• Surface-mount SOT-23 packaging facilitates automated assembly and compact circuit board layouts.
• High thermal stability supports operation across extended industrial temperature ranges.

Applications

• Battery protection circuits
• Overvoltage crowbar protection
• General purpose switching

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the tape and reel configuration. Ensure that the procurement request explicitly references the CMPS5064 part number to distinguish it from through-hole variants or other family members. Confirm RoHS compliance status directly with the supplier prior to finalizing orders.

Selection Notes

Select this component when a surface-mount SCR with a 400 V blocking capability is required. The sensitive gate characteristic makes it suitable for applications where minimal gate drive current is available. Verify that the SOT-23 package dimensions fit the design constraints and that the 160 mA average current rating meets the load requirements.

Part Context

This component belongs to the Central Semiconductor thyristor family, specifically engineered for modern electronics requiring small form factors. The CMPS5064 variant replaces older through-hole designs in space-constrained applications while maintaining robust electrical performance standards typical of the manufacturer's discrete semiconductor portfolio.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult the manufacturer's official cross-reference guides or contact technical support directly to identify equivalent components with matching electrical specifications and package footprints.
