Product overview

Description

The SMAJ Transil series has been designed to protect sensitive equipment against electrostatic discharges according to IEC 61000-4-2, and MIL STD 883, method 3015, and electrical over stress according to IEC 61000-4-4 and 5. These devices are generally used against surges below 400 W (10/1000 μs). Planar technology makes these devices suitable for high-end equipment and SMPS where low leakage current and high junction temperature are required to provide reliability and stability over time.
SMAJ are packaged in SMA (SMA footprint in accordance with IPC 7531 standard).
  • All features

    • Peak pulse power:
      • 400 W (10/1000 μs)
      • 2.3 kW (8/20 μs)
    • Stand off voltage range: from 5 V to 188 V
    • Unidirectional and bidirectional types
    • Low leakage current:
      • 0.2 μA at 25 °C
      • 1 μA at 85 °C
    • Operating Tj max: 150 °C
    • High power capability at Tj max:
      • 270 W (10/1000 μs)
    • JEDEC registered package outline
    • Complies with the following standards
      • IEC 61000-4-2 level 4
        • 15 kV (air discharge)
        • 8 kV (contact discharge)
      • IEC 61000-4-5 (see Table 3 for surge level)
      • MIL STD 883G, method 3015-7 Class 3B
        • 25 kV HBM (human body model)
      • Resin meets UL 94, V0
      • MIL-STD-750, method 2026 solderability
      • EIA STD RS-481 and IEC 60286-3 packing
      • IPC 7531 footprint
