• Current - Collector Cutoff (Max): ≤ 10 µA
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Power - Max: Equal to or greater than 1.75 W
• Frequency - Transition: Equal to or greater than 60 MHz
• Operating Temperature Range: Equal to or greater than -65°C to 150°C
• Product Status: Active substitutes preferred for obsolete main part

Three substitute parts meet these criteria and are listed below.
