The PLANET family of discrete products from CISSOID has been expanded with CHT-AMALTHEA, a medium power, general purpose, dual diode in a hermetically sealed metal can TO-257 package. This new device is guaranteed for operation from -55 °C up to +225 °C. CHT-AMALTHEA includes two diodes and is available in three possible configurations: Common anode, common cathode and dual series configurations.
Each diode has a reverse voltage of 80 V, a maximum forward current of 3 A DC and 4 A peak at 225 °C, making them suitable for a number of power applications. The metal, TO-257 package is isolated from the pins, facilitating the mechanical assembling of the systems. This dual diode is a general purpose, discrete component that can be used in a variety of medium power applications, including rectification, free-wheeling, clamping and sensing, among others.
CHT-AMALTHEA diodes present a junction capacitance of 36 pF and 56 pF at 20 V and 80 V reverse voltages respectively. A rectifier bridge can easily be implemented by using two AMALTHEA. Each diode has a forward voltage of 1.53 V typ. at 225 °C (and at 2 A forward current) and presents a very low leakage current of 15 µA at 80 V reverse voltage and at 225 °C.
Pricing starts at $181.16 for 51 to 200 units.
