1N5235A

Single Zener Diodes Overview

The Microchip Technology 1N5235A is a 6.8 V Zener diode housed in a DO-35 glass axial-lead package. It features a maximum power dissipation of 0.5 W and a voltage tolerance of ±10%. The device operates within a temperature range of -65°C to +175°C, with a nominal test current of 20 mA. Key electrical parameters include a maximum reverse leakage current of 50 µA at 4.8 V, a Zener impedance of 5 Ω at the test current, and a positive voltage temperature coefficient of +0.050 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features hermetically sealed glass DO-35 construction for environmental durability
• Offers minimal capacitance characteristics suitable for high-frequency applications
• Includes flexible axial-lead mounting terminals for standard through-hole integration

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clamping applications for transient suppression
• Biasing networks for semiconductor devices

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the 'A' suffix to confirm the required ±10% voltage tolerance. Ensure the procurement specification matches the manufacturer's JEDEC registration standards. Confirm compliance with RoHS requirements if applicable by checking for the 'e3' designation on the component marking or ordering documentation.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V reference is needed with moderate tolerance accuracy. The DO-35 package is appropriate for through-hole designs where space constraints are not critical. Consider the positive temperature coefficient for thermal stability analysis in environments with significant ambient temperature fluctuations.

Single Zener Diodes Part Context

This component belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series provides a wide selection of voltages from 2.4 V to 200 V. The 'A' suffix specifically denotes a standard 10% voltage tolerance, distinguishing it from tighter tolerance variants like the 'B' (±5%) or 'C' (±2%) suffixes within the same family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5235A parts meeting identical JEDEC specifications. Equivalent options may include the 1N5235B variant if tighter ±5% tolerance is acceptable. Surface mount equivalents such as the MLL5235A in DO-213AA MELF style are available for board space optimization.
