NOTES : 1.VBR measured after IT applied for 300µs. IT = Square Wave Pulse or equivalent.
2.For bidirectonal use C or CA suffixs for all types (ex. SMAJ5.0C, SMAJ170CA).
electrical characteristics apply in both directions.
3.For bidirectional types having VWM of 10 volts and less, the ID limit is doubled.
