NOTES:
1- Non-repetitive current pulse, per Fig.3 and derated above TA = 25°C per Fig. 2.
2- Mounted on 0.31 x 0.31” (8.0 x 8.0mm) copper pads to each terminal
3- Mounted on minimum recommended pad layout
4- VF = 3.5V for 1.5SMC200(A) & below; VF = 5.0V for 1.5SMC220(A) & above
Devices for Bidirectional Applications:
1- For bi-directional, use C or CA suffix for types 1.5SMC6.8 thru types 1.5SMC440A(e.g. 1.5SMC6.8C, 1.5SMC440CA).
2- Electrical characteristics apply in both directions.
