Features

Mechanical data

Molded plastic, JEDEC MiniSMA/SOD-123.

-Weight:0.027 gram(approx.).

-Batch process design, excellent powe

dissipation offers better reverse leakage

current and thermal resistance.

-Low profile surface mounted application

in order to optimize board space.

-Tiny plastic SMD package.

-Low power loss, high efficiency.

-High current capability, low forward voltage dorp.

-High surge capability.

-Guardring for overvoltage protection.

-Ultra high-speed switching.

-Silicon epitaxial planarchip, metal silicon junction.

-Lead-free parts meet environmental

standards of MIL-STD-19500 /228

-Case:

-Terminals: Solde plated, solderable per

MIL-STD-750, method 2026.

-Polarity: Indicated by cathode band.

-Mounting position: Any
