The single bidirectional channel handles both positive and negative transients, reducing component count on AC-coupled or bipolar circuits. ## Clamp voltage and pulse current At the 21.4A peak pulse current (10/1000µs), the clamping voltage maxes at 70.1V. That ceiling tells the designer the protected device sees no more than 70.1V during a surge — key for 48V bus or 36V battery systems where downstream ICs have a 75V absolute max. The 48.5V minimum breakdown voltage ensures the diode does not conduct during normal rail ripple up to 38.8V, leaving margin for transients without nuisance triggering. Housed in a hermetic SQ-MELF C package, the 1N6159AUS is a surface-mount device with a ceramic body that resists moisture and thermal shock better than plastic SMD packages. The SQ-MELF footprint is non-standard — verify the land pattern against the package drawing before committing the PCB layout. The base product number 1N6159 supports multiple voltage variants in the same SQ-MELF package.
