CS89M TR PBFREE

Scrs Overview

The CS89M TR PBFREE is a surface-mount silicon Silicon Controlled Rectifier (SCR) manufactured by Central Semiconductor Corp. It features a standard recovery characteristic with a maximum off-state voltage of 600 V and a gate trigger voltage maximum of 800 mV. The device is rated for an RMS on-state current of 0.8 A and is housed in a SOT-89 package. This component is designed for applications requiring reliable switching in compact form factors, offering robust performance within its specified electrical limits.

Scrs Feature Summary

• Surface mount construction utilizing SOT-89 packaging for space-constrained designs
• Standard recovery characteristics suitable for general-purpose switching applications
• High off-state voltage rating of 600 V for robust circuit protection

Scrs Applications

• General purpose AC/DC switching circuits
• Overvoltage protection devices
• Triggering circuits for power control systems

Scrs Procurement Notes

Verify the specific ordering suffix requirements when sourcing lead-free plated devices from Central Semiconductor Corp. The manufacturer specifies adding the 'PBFREE' suffix to the base part number during the ordering process to ensure compliance with lead-free standards. Confirm availability status as distribution channels may vary for this specific surface-mount SCR variant.

Scrs Selection Notes

Select this component when a surface-mount SCR with a 600 V blocking capability is required in a SOT-89 footprint. Ensure the application current does not exceed the 0.8 A RMS rating. Consider thermal management requirements inherent to the small outline package. Verify that the gate trigger voltage specifications align with the driving circuit capabilities.

Scrs Part Context

This SCR belongs to Central Semiconductor's discrete semiconductor portfolio, which includes various standard and niche devices. The company specializes in both through-hole and surface-mount technologies. The CS89M series represents their surface-mount SCR offerings, providing alternatives to traditional axial-leaded components for modern PCB layouts.

Scrs Replacement Considerations

Direct substitutes must match the 600 V rating, 0.8 A current capacity, and SOT-89 package. Cross-reference datasheets for equivalent SCRs from other manufacturers ensuring identical pinout configuration and electrical parameters. Verify compatibility with existing board space and thermal constraints.
