The IXYS DSSK40-008B is a high-performance Schottky diode array featuring a common cathode configuration with two diodes in a single TO-247AD package. Each diode is rated for a maximum reverse voltage of 80V and an average forward current of 20A (40A per device). The typical forward voltage is as low as 0.52V at 20A and 125°C, enabling low conduction losses.
This diode array is designed for rectification and freewheeling applications in switch-mode power supplies (SMPS) and low-voltage converters. It offers extremely low switching losses and a high surge capability of 500A non-repetitive peak forward current. The device also features an avalanche energy rating of 20mJ, enhancing robustness in harsh environments.
Thermally, the DSSK40-008B can operate over a junction temperature range of -55°C to 150°C, with a maximum power dissipation of 115W at case temperature 25°C. The junction-to-case thermal resistance is typically 1.1 K/W, and the case-to-heatsink thermal resistance is 0.25 K/W, facilitating efficient heat management.
The through-hole mounting TO-247-3 package (supplier package TO-247AD) allows easy integration into power circuits. The package meets UL 94V-0 flammability rating and has a recommended mounting torque of 0.8 to 1.2 Nm. Typical weight is 6 grams.
The maximum reverse voltage (VRRM) is 80 V.
The average forward current is 40 A per device (dual diode) and 20 A per diode at TC = 130°C with rectangular waveform, duty cycle 0.5.
The typical forward voltage is 0.52 V at IF = 20 A and TVJ = 125°C; 0.58 V at 25°C; 0.68 V at IF = 40 A and 125°C.
It is available in a TO-247-3 through-hole package, supplier device package TO-247AD.
The operating junction temperature range is -55°C to +150°C, with a maximum junction temperature of 150°C.
Maximum power dissipation is 115 W at case temperature 25°C.
The diode configuration is 1 pair common cathode.
