Good design practice should limit the maximum continuous current through the main terminals to 75% of the component rating. Other ways to ensure long life for a power discrete semiconductor are proper heat sinking and selection of voltage ratings for worst case conditions. Overheating, overvoltage (including dv/dt), and surge currents are the main killers of semiconductors. Correct mounting, soldering, and forming of the leads also help protect against component damage. ## **Environmental Specifications** **==> picture [234 x 162] intentionally omitted <==** **----- Start of picture text -----**<br> ||| |---|---| |Test|Specifications and Conditions| |MIL-STD-750, M-1040, Cond A Applied| |AC Blocking (VDRM)|Peak AC voltage @ 150°C for 1008 hours| |MIL-STD-750, M-1051,| |Temperature Cycling|100 cycles; -55°C to +150°C; 15-min| |dwell-time| |EIA / JEDEC, JESD22-A101| |Temperature/Humidity|1008 hours; 160V - DC: 85°C; 85%| |rel humidity| |MIL-STD-750, M-1031,| |High Temp Storage| |1008 hours; 150°C| |Low-Temp Storage|1008 hours; -40°C| |Resistance to| |MIL-STD-750 Method 2031| |Solder Heat| |Solderability|ANSI/J-STD-002, category 3, Test A| |Lead Bend|MIL-STD-750, M-2036 Cond E| **----- End of picture text -----**<br> © 2021 Littelfuse, Inc.

Updated at June 8, 2026
Founded in 1927 and headquartered in Chicago, Illinois, Littelfuse is a premier global manufacturer of circuit protection, power control, and sensing technologies. Widely recognized for pioneering the first small, fast-acting protective fuse, the company has grown into an industry leader whose highly reliable components are essential to modern industrial, transportation, and consumer electronics applications worldwide. At the core of the Littelfuse portfolio is an expansive and industry-leading range of circuit protection solutions. This encompasses a massive selection of traditional fuses, fuse holders, and resettable PTC thermistor fuses designed to safely interrupt overcurrent conditions. To defend against electrical overstress, Littelfuse also provides advanced transient voltage suppression (TVS) technologies, including thousands of specialized TVS diodes, TVS varistors, and gas discharge tubes (GDTs) that ensure robust defense against voltage spikes and environmental hazards. Beyond its foundational protection components, Littelfuse manufactures a diverse array of discrete semiconductors, sensors, and switching devices. Engineers rely on their high-performance thyristors, including TRIACs and SCRs, alongside power-efficient Schottky diodes and MOSFETs for demanding power control applications. Complemented by precision proximity sensors and highly reliable reed and solid-state relays, Littelfuse delivers the critical building blocks required for secure, efficient, and complete system design.
About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 540,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
