MD165C16D2
The MD165C16D2 is a rectifier diode module designed for reliable operation in high-power electronic systems. With a repetitive peak reverse voltage of 1600 V and an average forward current of 165 A at Tc = 101 °C, it ensures stable rectification in motor controllers, AC/DC converters, and field supply units. Its high surge current capability of 6000 A makes it suitable for demanding industrial conditions where both continuous operation and short-term overloads must be handled effectively.
This module uses glass-passivated chips for controlled leakage and durability, combined with an aluminum-oxide isolated metal baseplate for efficient heat transfer. Forward voltage drop remains low, typically 1.20 V at 300 A, minimizing conduction losses. Thermal resistance values of 0.21 °C/W per diode and 0.05 °C/W for the case-to-sink interface simplify cooling and contribute to long service life even in intensive duty cycles.
The MD165C16D2 is built in a D2 chassis-mount package with M6 screw terminals, offering straightforward integration and strong electrical isolation of 3000 Vrms for 1 minute. With an operating junction temperature range from –40 °C to +150 °C, it adapts well to industrial and commercial environments, including inverters, UPS systems, and rectifier banks.
