1N5235B

Single Zener Diodes Overview

The onsemi 1N5235B is a single silicon Zener diode housed in a hermetically sealed glass axial-lead DO-204AH (DO-35) package. It provides a nominal Zener voltage of 6.8 V with a ±5% tolerance, tested at 20 mA. The device dissipates up to 500 mW and features a maximum dynamic impedance of 5 Ω at the test current. Reverse leakage current is limited to 3 µA at 5 V reverse bias. It operates within a junction temperature range of −65°C to +200°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for environmental stability
• Precise voltage regulation with tight manufacturing tolerances
• High thermal endurance supporting extreme operating temperatures

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection networks
• Voltage regulator power supplies

Single Zener Diodes Procurement Notes

Verify that the ordered component matches the specific 1N5235B designation from Semiconductor Components Industries, LLC. Confirm the package type is the standard axial lead variant unless a tape and reel suffix is explicitly required. Ensure compliance with RoHS and halide-free specifications as defined in the official ordering information.

Single Zener Diodes Selection Notes

Select this component when a stable 6.8 V reference is needed in a through-hole design. The low dynamic impedance supports accurate regulation under varying load conditions. Verify that the 500 mW power dissipation rating accommodates the expected thermal environment without exceeding the derating limits above 50°C.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5252B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 V to 24.0 V in standard 5% or 10% tolerances. All devices share the same robust glass axial-lead packaging designed for reliable performance in general-purpose electronic applications.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5235B parts. Verify that replacement units maintain the 6.8 V nominal voltage, 500 mW power rating, and DO-204AH package dimensions to ensure mechanical and electrical compatibility.
