Heat sink designed for MD MDK blocking diodes, solar diodes, antireverse one way diodes and H110 radiator type solid state relay applications. Provides reliable thermal management to reduce junction temperature and maintain stable operation under continuous current loads. Key benefits Keeps diodes and solid state relays cooler to reduce thermal stress and improve long term reliability. Supports current diode assemblies rated for 55A, 110A, and 250A, providing the thermal capacity needed for demanding setups. Simple, direct mounting to diode or SSR packages for fast installation and secure thermal contact. Compact profile that adds cooling without significantly increasing footprint or obstructing surrounding components. What this product does Conducts heat away from diode junctions and SSR cases to lower operating temperatures during charge, discharge, or switching cycles. Reduces the risk of thermal shutdown, thermal runaway, and reduced performance caused by accumulated heat. Enables more consistent electrical performance when diodes or SSRs operate near their rated current. Compatibility and models Specifically compatible with MD MDK blocking diodes and similar solar diode modules. Suited for antireverse one way diodes rated at 55A, 110A, and 250A. Designed to work with H110 radiator style solid state relays and similar SSR packages that require additional external cooling.
