The VSMY7852X01 and VSMY7850X01 are high power and very low thermal resistivity infrared emitters. They can be operated continuously or pulsed. The VSMY7852X01 contains a 20 mil chip and can be driven continuously up to 250 mA or pulsed up to 1.5 A while keeping optical power and intensity linear. The VSMY7850X01 contains a 42 mil chip, can be driven continuously up to 1 A DC or pulsed up to 5 A. Both emitters are AEC-Q101 qualified for automotive applications.
