Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and quantity. Standard configurations include reel or ammo box packing. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement.

Single Zener Diodes Selection Notes

Select this component based on the required 33 V regulation point and 1.3 W power handling capability. Ensure the application environment remains within the specified -65 °C to +200 °C operating temperature range. Verify that the circuit design accommodates the 35 Ω dynamic impedance and 8 mA test current requirements for accurate voltage stabilization.

Single Zener Diodes Part Context

This part belongs to the BZX85C series of silicon planar power Zener diodes produced by Taiwan Semiconductor. The series covers a broad voltage spectrum from 3.3 V to 56 V, all sharing the same DO-41 axial leaded package and 1.3 W power rating profile. These components are designed for general-purpose voltage regulation and clipping circuits.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' DO-41 packaged Zener diodes rated for 33 V, 1.3 W, and ±5% tolerance. Ensure equivalent thermal resistance and hermetic sealing specifications are met before substitution.
