The Microsemi high conductivity design, using a heavy copper top post and 4point crimp, ensures cool thermal operation and low dynamic impedance with applicable heat sinking for peak repetitive forward currents up to 150 Amps at 50% duty cycle. This rugged DO-5 hermetically sealed design absorbs stress that can otherwise damage glass-to-metal seals during installation and operation. It is also available in a flexible top lead as described herein. IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com APPEARANCE DO-5 W WW. Microsemi .
