LIC01-195H

Overview

The STMicroelectronics LIC01-195H is a high voltage breakover diode designed for light ignition circuits. It operates with a minimum breakdown voltage of 195 V and a maximum of 230 V at 25°C. The device supports a repetitive surge peak on-state current of ±50 A (10 µs pulse) and an RMS on-state current of 1.2 A at 90°C ambient temperature. It features a holding current greater than 50 mA and a critical rate of rise on-state current of 80 A/µs. The component is housed in an IPAK plastic package, operating within a junction temperature range of -20°C to 125°C.

Feature Summary

• Monolithic integration of high voltage breakover functionality
• High reliability planar diffused technology construction
• Direct operation capability on 220/240 VAC mains circuits

Applications

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

Procurement Notes

Verify the specific ordering suffix 'H' corresponds to the IPAK package configuration as defined in the manufacturer's documentation. Confirm that the electrical parameters align with system requirements before procurement. Ensure compliance with the manufacturer's restrictions regarding use in life support devices or systems without express written approval.

Selection Notes

Select this component when designing circuits requiring a precise high voltage trigger threshold between 195 V and 230 V. Consider the thermal resistance values and maximum lead soldering temperature limits during PCB layout. Evaluate the holding current specifications against the circuit's leakage characteristics to ensure reliable turn-off behavior after the ignition pulse.

Part Context

This device belongs to the LIC01 Series, which includes variants such as the LIC01-215H offering higher breakdown voltage thresholds. The series utilizes planar technology suitable for rugged environmental conditions and high surge current operations. Other package options within the family include the DPAK configuration, identified by the 'B' suffix in the ordering information.
