Parameter Comparison

Engineering Selection Recommendations

The BZX79-B3V0,133 is a direct electrical and mechanical equivalent to the BZX79-B3V0,113. Both parts are manufactured by Nexperia/NXP, share identical electrical specifications, and are packaged in the same DO-204AH axial configuration. Both parts maintain active product status and comply with export control classifications (EAR99) and tariff codes (HTSUS 8541.10.0050).

The primary distinction between these parts is packaging format: the BZX79-B3V0,113 is supplied in Tape & Reel (TR) configuration, while the BZX79-B3V0,133 is supplied in Bulk packaging. This difference affects procurement and handling procedures but does not impact electrical performance or circuit compatibility.

Selection between these parts should be based on procurement requirements, inventory availability, and packaging format compatibility with assembly processes. Both parts are suitable for applications requiring 3 V zener regulation with 400 mW power dissipation in through-hole circuit designs.
