LIC01-215H

Overview

The STMicroelectronics LIC01-215H is a high voltage breakover diode designed for light ignition circuits. It operates in the IPAK package and features a minimum breakover voltage of 215 V with a maximum of 255 V at 25°C. The device 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. It exhibits a holding current greater than 50 mA and can withstand a critical rate of rise on-state current of 80 A/μs. The component functions by switching from an off-state to a low voltage on-state when the applied voltage exceeds the breakover threshold, returning to the off-state once the current drops below the holding level.

Feature Summary

• Monolithic integration of high voltage breakover functionality within a rugged planar diffused structure
• High surge current pulse capability suitable for direct operation on 220/240 VAC mains circuits
• Space-saving design achieved through integrated circuit architecture

Applications

• Light ignitors for high pressure sodium lamps
• Lamp flashing circuits
• Light ignitors for metal halide lamps

Procurement Notes

Verify the specific ordering suffix to confirm the package type before procurement. The 'H' suffix indicates the IPAK plastic package, while the 'B' suffix corresponds to the DPAK variant. Ensure that the required thermal management aligns with the junction-to-ambient resistance specifications provided in the datasheet. Confirm that the application environment remains within the specified operating junction temperature range of -20 to +125 °C.

Selection Notes

Select the LIC01-215H when a higher breakover voltage threshold is required compared to the 195 V variant. This model provides a minimum breakover voltage of 215 V, making it suitable for applications where the trigger voltage must be set above standard line peaks without premature firing. Consider the IPAK package for through-hole mounting requirements and verify that the 1.2 A RMS current rating meets the load demands of the ignition transformer primary circuit.

Part Context

The LIC01 series consists of application-specific discretes engineered for high voltage pulse generation. The family includes the LIC01-195 and LIC01-215 variants, differentiated primarily by their breakover voltage ranges. These devices utilize planar technology to ensure reliability under harsh environmental conditions and high surge currents typical in lighting ballast systems.
