The SMA4FY Transil series are designed to protect sensitive automotive circuits against surges and against electrostatic discharges. The Planar technology makes it compatible with high-end circuits where low leakage current and high junction temperature are required to provide long term reliability and stability.

Peak pulse power: 400 W (10/1000 μs) and 2.5 kW (8/20 μs)

Flat and thin package: 1 mm

Stand-off voltage range from 5 V to 188 V

Unidirectional type

Low leakage current: 0.2 μA at 25 °C and 1 μA at 85 °C

Operating Tj max: 175 °C

High power capability at Tj max.: up to 200 W (10/1000 μs)

Lead finishing: matte tin plating
