    • 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
