Frequently Asked Questions
What is the maximum reverse voltage (VR) for SMBD 2837 and SMBD 2838?
The maximum specified Reverse Voltage (VR) is 30V for SMBD 2837 and 50V for SMBD 2838.
What is the maximum allowed total power dissipation?
The maximum Total Power Dissipation (Ptot) listed for both models is 250 mW.
How quickly does the diode recover during switching operations?
The reverse recovery time (trr) is 0.6 ns when measured at IR = 1 mA, and 0.35 ns when measured at Rj = 50 Ω.
What is the maximum recommended junction-to-ambient thermal resistance?
The Junction - ambient thermal resistance (Rth JA) must be less than or equal to 600 K/W.
