1N5235B-T

Single Zener Diodes Overview

The Vishay 1N5235B-T is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides a nominal Zener voltage of 6.8 V with a standard tolerance of ±5%. The device dissipates up to 500 mW at thermal equilibrium and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum reverse leakage current of 3 µA, a dynamic impedance of 5 Ω, and a typical voltage temperature coefficient of 0.05 %/K.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Provides stable reference voltages across a wide operating temperature range
• Features low forward voltage drop under high current conditions

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'TR' suffix to confirm taped-and-reeled packaging. Ensure the 'B' suffix is present to guarantee the specified ±5% voltage tolerance. Cross-reference the document number 85588 to access the latest electrical specifications and absolute maximum ratings before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V reference is required in an axial through-hole package. The 500 mW power dissipation rating supports moderate current loads. Verify that the 5 Ω dynamic impedance meets the circuit's ripple rejection requirements. Confirm compatibility with the DO-35 footprint during PCB layout.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a broad Zener voltage range from 2.4 V to 75 V. The 1N5235B variant specifically targets applications requiring a 6.8 V breakdown voltage with standard commercial-grade tolerance.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay series include 1N5235B-TR and 1N5235B-TAP. Other manufacturers producing equivalent DO-35 6.8 V Zener diodes may be considered if they meet the 500 mW power and ±5% tolerance specifications.
