Electrical performance and heat dissipation of BAS20DWQ-13

The electrical behavior of the BAS20DWQ-13 is tailored for demanding switching applications. Each diode within the array delivers a continuous forward current of 200 mA, with the device rated for a reverse voltage of up to 150 V. When both diodes are loaded in parallel, the total current capability remains at 200 mA; for series or individual loading, designers should halve the continuous forward current per terminal. The device features fast turn-on/turn-off characteristics and low leakage current, supporting precision and efficiency. Standard operation is specified at 25°C ambient, with corresponding thermal derating curves available to guide proper design in higher temperature environments. For in-depth selection and simulation, typical characteristics—forward voltage response, reverse current, and junction capacitance versus voltage—are provided, facilitating thorough system validation.
