Planar passivated Silicon Controlled Rectifier (SCR) in a SOT78 (TO-220AB) plastic package intended for use in applications requiring very high inrush current capability, high thermal cycling performance and high junction temperature capability (Tj(max) = 150 °C).

Features and Benefits
• High junction operating temperature capability (Tj(max) = 150 °C)
• Very high current surge capability
• Planar passivated for voltage ruggedness and reliability
• High turn-on current rise dIT/dt = 100 A/μs
• High noise immunity dVD/dt = 500 V/μs up to 150 °C
• High thermal cycling performance
• High voltage capability
• Ignition circuits
• Protection circuits e.g. SMPS inrush current
• Motor control circuits and starters
• Voltage regulation
• Solid state relays
• High junction operating temperature capability (Tj(max) = 150 °C)
