Central Semiconductor Corp. Programmable Unijunction CMPP6028 TR PBFREE

The CMPP6028 is a surface mount silicon programmable unijunction transistor in an SOT-23 package, designed for adjustable characteristics including peak current, valley current, and intrinsic standoff ratio. It has a maximum anode-cathode voltage of 40 V, peak repetitive forward current of 1.0 A (t=100μs, D.C.=1.0%), and DC forward anode current of 150 mA. Power dissipation is rated at 167 mW with a thermal resistance of 450 °C/W when mounted on a 2 inch square FR-4 PCB. The gate-cathode reverse voltage is limited to 5.0 V. Operating junction temperature ranges from -50 to +100 °C. The part features a peak current of up to 1.0 μA at VS=10V and RG=10kΩ, and a valley current of 25 μA at the same conditions. The intrinsic standoff ratio is characterized with a threshold voltage ranging from 0.2 to 0.6 V under specified test conditions.
