ZPD4B3

Single Zener Diodes Overview

The ZPD4B3 is a single Zener diode manufactured by Diotec Semiconductor, designed for voltage stabilization and regulation applications. It utilizes a DO-35 axial through-hole package with dimensions of 1.9 mm diameter and 3.9 mm length. The device features a nominal Zener voltage (Vz) of 4.3 V with a standard tolerance of ±5%. It supports a maximum power dissipation (Pd) of 500 mW at an ambient temperature up to +175°C, operating reliably within a junction temperature range of -50°C to +175°C. Key electrical characteristics include a test current of 5 mA, a Zener impedance (Zz) of 80 Ohms, and a maximum reverse leakage current (Ir) of 100 nA.

Single Zener Diodes Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm compliance with current environmental standards such as RoHS and REACH. Ensure that the selected component matches the required voltage tolerance and power dissipation ratings for the intended application environment. Cross-reference technical specifications with the latest datasheet to validate operational limits and packaging details before finalizing procurement decisions.

Single Zener Diodes Selection Notes

Select the ZPD4B3 when a stable 4.3 V reference is required in through-hole designs. Consider its 500 mW power rating and wide temperature range for robust commercial applications. Verify that the 80 Ohm impedance and low leakage current meet circuit sensitivity requirements. Confirm compatibility with assembly processes suitable for the DO-35 package format.

Single Zener Diodes Part Context

The ZPD4B3 belongs to the ZPx series of Zener diodes from Diotec Semiconductor. This series is characterized by sharp breakdown voltages and low leakage currents, making it suitable for general-purpose voltage regulation. The components are graded to the international E24 standard for voltage tolerance, ensuring consistency across production batches for reliable circuit performance.

Single Zener Diodes Replacement Considerations

Consult official substitution lists or manufacturer notices for verified alternative part numbers. Do not assume functional equivalence with other Zener diodes without verifying electrical parameters and package compatibility.
