Frequently Asked Questions
What is the reverse voltage rating of the AVX SD1206T040S1R0 Schottky diode?
The SD1206T040S1R0 is rated for a 40 V reverse voltage, making it suitable for general-purpose rectification on power rails up to approximately 24 V with adequate derating. Its single-element silicon Schottky construction provides a low forward voltage drop—typically around 0.3 V to 0.5 V—which reduces power dissipation in switching circuits.
Which power supply topologies are best matched to the SD1206T040S1R0 in a 5 V to 12 V output design?
The SD1206T040S1R0 fits well in buck converter output rectification, flyback diode positions, and half-wave rectifier stages operating at 5 V to 12 V outputs. Its 40 V rating provides margin well above the peak voltages seen in these topologies, and the low power loss in the 1206 package keeps junction temperatures manageable at typical load currents of 1 A or less.
How does the 1206 chip package of the SD1206T040S1R0 compare to SOD-123 or SOD-323 packages for board space?
The 1206 chip package (3.2 mm × 1.6 mm) is larger than the SOD-123 (3.5 mm × 1.7 mm profile but shorter body) and significantly larger than the SOD-323 (1.7 mm × 1.25 mm). However, 1206 provides a larger pad area, improving solder joint reliability and thermal dissipation for designs where board space is not the primary constraint.
When is SD1206T040S1R0 preferred over a standard PN junction rectifier diode in high-frequency switching designs?
In switching designs operating above 100 kHz, the SD1206T040S1R0's Schottky construction eliminates the stored minority carrier charge that causes reverse recovery losses in PN junction diodes. With essentially no reverse recovery time, it reduces switching losses and electromagnetic interference in circuits where the rectifier switches at 100 kHz to several MHz.
