LIC01-215B-TR

DIACs, SIDACs Overview

The STMicroelectronics LIC01-215B-TR is a high-voltage breakover diode designed for light ignition circuits, specifically for high-pressure sodium and metal halide lamps. It operates directly on 220/240 VAC mains to generate high voltage pulses. The device features a minimum breakover voltage of 215 V and a maximum holding current exceeding 50 mA. It supports a repetitive surge peak on-state current of ±50 A and an RMS on-state current of 1.2 A at 90°C ambient temperature. The component utilizes planar diffused technology for high reliability and is housed in a DPAK package.

DIACs, SIDACs Procurement Notes

Verify the specific suffix 'B' corresponds to the DPAK plastic package as indicated in the ordering information section. Confirm that the 'TR' designation aligns with the manufacturer's standard tape and reel delivery mode, as the datasheet explicitly lists tube packaging for the base part numbers. Ensure the required breakover voltage range matches the 215V specification variant.

DIACs, SIDACs Selection Notes

Select this component when designing ignition circuits requiring direct connection to 220/240 VAC mains without complex driver stages. The 215V minimum breakover voltage makes it suitable for applications where higher trigger thresholds are needed compared to the 195V variant. Consider the thermal resistance of 100 °C/W for junction-to-ambient calculations to ensure safe operating temperatures under continuous pulsing conditions.

DIACs, SIDACs Part Context

This device belongs to the LIC01 Series, a family of application-specific discretes engineered for light ignition. The series includes variants with different breakover voltages, such as the LIC01-195. The product line leverages STMicroelectronics' planar diffused technology to provide robust performance in high surge current operations typical of lamp starting applications.

DIACs, SIDACs Replacement Considerations

The datasheet does not list specific substitute part numbers. Engineers should evaluate other high-voltage breakover diodes from the same manufacturer or industry peers that offer comparable breakover voltage ranges and surge current capabilities.
