      • 600 W (10/1000 μs)
      • 4 kW (8/20 μs)
    • Stand-off voltage 213 V
    • Bidirectional type
    • Low leakage current:
      • 200 nA at 25 °C
      • 1 μA at 85 °C
    • Operating Tj max: 175 °C
    • High power capability at Tj max
    • JEDEC registered package outline
    • Resin meets UL 94, V0
    • AEC-Q101 qualified
    • Complies with the following standards
      • IEC 61000-4-2 exceeds level 4:
        • 30 kV (air discharge)
        • 30 kV (contact discharge)
      • ISO 10605, C = 330 pF, R = 330 Ω exceeds level 4:
        • 30 kV (air discharge)
        • 30 kV (contact discharge)
      • ISO 7637-2
