SMA6J High junction temperature Transil™ Features ■ Peak pulse power: – 600 W (10/1000 µs) – 4 kW (8/20 µs) ■ Stand off voltage range: from 5 V to 188 V ■ Unidirectional and bidirectional types ■ Low clamping voltage versus standard series ■ Low leakage current: – 0.2 µA at 25° C – 1 µA at 85° C ■ Operating Tj max: 175° C ■ JEDEC registered package outline A K Unidirectional Bidirectional SMA (JEDEC DO-214AC) Description The SMA6J Transil series has been designed to protect sensitive equipment against electro-static discharges according to IEC 61000-4-2, MIL STD 883 Method 3015, and electrical over stress such as IEC 61000-4-4 & 5. They are also in accordance with ISO TR 7637-2, SAE J 113 and DIN 40839 for automotive applications and more generally for surges below 600 W 10/1000 µs This Planar technology makes it compatible with high-end equipment like automotive, medical equipment or SMPS where low leakage current and high junction temperature are required to provide reliability and stability over time. Their low clamping voltages provides a better safety margin to protect sensitive circuits with extended life time expectancy. Packaged in SMA, this minimizes PCB consumption (SMA footprint in accordance with IPC 7531 standard). Order code Part number Marking SMA6JxxA-TR See Table 6. SMA6JxxCA-TR See Table 6.
