Heatsinks O371 are designed for power diodes and thyristors in SА1 stud housings.
The dissipation power with natural cooling is 50 W. This type of cooling benefits from simple design, minimal noise, high reliability, low cost, easy operation and repairs. Alternatively, dissipation power may be increased with forced cooling in more intensive operation modes.
The heatsink is made of aluminum reducing its weight to only 0.40 kg including current lead.
The heatsink is mounted using a threaded connection. To ensure optimal heat dissipation values it is necessary to maintain specified torque moment.
Compact size makes O371 a good choice for operation in limited space.
Proton-Electrotex designs and manufactures own heatsinks for its semiconductors, allowing the company to offer efficient solutions for reliable heat removal.
Proton-Electrotex is able to select suitable heatsink model for specific operation modes on customer’s request. It is also possible to order complete, ready-to-use power semiconductors in assembly with the heatsink.
