Description
Complies with the following standards
IEC 61000-4-2 level 4:
– 15 kV (air discharge) – 8 kV (contact discharge)
IEC 61000-4-5
MIL STD 883G, method 3015-7 Class 3B:
– 25 kV HBM (human body model)
Resin meets UL 94, V0
MIL-STD-750, method 2026 soldererability
EIA STD RS-481 and IEC 60286-3 packing
IPC 7531 footprint
The SMBJ 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 more generally used against surges below 600 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.
SMBJ are packaged in SMB (SMB footprint in accordance with IPC 7531 standard).
