N O T E S : 1.V BR measured after I T applied for 300µs. I T = 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 V WM of 10 volts and less, the I D limit is doubled.
