Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details such as reel size (7-inch or 13-inch) and quantity per reel (5K or 12K). Confirm compliance requirements including RoHS status and halogen-free specifications before procurement. Ensure the marking code ACH matches the required identification for inventory tracking.

Single Zener Diodes Selection Notes

Select this component when a 4.3 V reference is required in a compact SMD form factor. Consider the 500 mW power dissipation limit and thermal resistance of 250 °C/W for heat management. Evaluate the 95 Ω impedance for noise sensitivity in precision applications. Verify that the operating temperature range meets the environmental conditions of the target system.

Single Zener Diodes Part Context

This part belongs to the PZS524V3BCH series, which covers Zener voltages from 4.3 V to 75 V. All devices in this series share the same SOD-323HE package and 500 mW power rating. The series utilizes planar die technology and is intended for high-volume automated surface mount assembly lines.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include PZS524V7BCH_R1_00001 and PZS525V1BCH_R1_00001. Cross-brand replacements require matching the 4.3 V nominal voltage, 500 mW power rating, and SOD-323HE package dimensions.
