SFR151 THRU SFR157
SOFT FAST RECOVERY RECTIFIERS
Reverse Voltage – 50 to 1000 Volts
Forward Current – 1.5 Amperes
Features
• Low forward voltage drop.
• High current capability.
• High reliability.
• High surge current capability.
• Fast switching for high efficiency.
Mechanical Data
• Cases: Molded plastic
• Lead: Axial leads, solderable per MIL-STD-202,
Method 208 guaranteed.
• Polarity: Color band denotes cathode end
• High temperature soldering guaranteed:
250oC/10 seconds/ 0.375”, (9.5mm) lead
lengths at 5 Ibs., (2.3kg) tension
Absolute Maximum Ratings and Characteristics
Rating at 25oC ambient temperature unless otherwise specified. Single-phase, half wave, 60Hz, resistive or inductive
load. For capacitive load, derate current by 20%.
