• Package: SOIC16
• Output Source / Sink Current: +3.5A source/-3.5A sink
• Vcc range: 10-20V w/ULVO
• Vbs range: 10-20V w/ULVO
• Typical propagation delay: 90/90ns On/Off

 AUIRGP50B60PD1 key highlights:

• Package: TO-247
• VCES: 600
• IC @25oC: 60A
• VCE(on) typ: 2.0V @33A
• Co-pack diode: 25A HEXFRED
• Qg: 205nC 

Pricing: In 100ku quantities, the AUIRS2191S begins at $1.35 each and the AUIRGP50B60PD1 at $3.78.
