VR	35 to 45 V

FEATURES

• 150 °C TJ operation

	• Center tap TO-247 package		Pb-free
			Available
	•	Very low forward voltage drop	RoHS*
	•	High frequency operation	COMPLIANT

• High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance

• Guard ring for enhanced ruggedness and long term reliability

• Lead (Pb)-free (“PbF” suffix)

• Designed and qualified for industrial level

DESCRIPTION

The 40CPQ...PbF center tap Schottky rectifier has been optimized for very low forward voltage drop with moderate leakage. The proprietary barrier technology allows for reliable operation up to 150 °C junction temperature. Typical applications are in switching power supplies, converters, freewheeling diodes, and reverse battery protection.
