1N5234B

Single Zener Diodes Overview

The onsemi 1N5234B is a single Zener diode with a nominal voltage of 6.2 V and a maximum power dissipation of 500 mW. It features a 5% tolerance, a test current of 20 mA, and a maximum Zener impedance of 7 Ω at the test current. The device has a maximum reverse leakage current of 5 μA and a typical voltage temperature coefficient of 0.045 %/°C. It operates within a junction temperature range of −65 °C to +200 °C and utilizes an axial lead glass package (DO-204AH).

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single unidirectional silicon Zener junction.
• Features a hermetically sealed glass axial-lead package designed for through-hole mounting.
• Maintains consistent performance across a wide operating temperature range from −65 °C to +200 °C.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection in electronic systems.
• General-purpose voltage regulation tasks.

Single Zener Diodes Procurement Notes

Verify that the ordered component matches the exact part number 1N5234B to ensure correct electrical characteristics. Confirm the package type is the standard axial lead variant. Check for specific suffixes if tape and reel packaging is required instead of bulk bags. Ensure compliance with RoHS and halide-free standards as specified by the manufacturer.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V regulation point is needed with a 500 mW power rating. Consider the 7 Ω impedance and 0.045 %/°C temperature coefficient for thermal stability requirements. Verify that the 20 mA test current aligns with the circuit design constraints. Ensure the operating environment stays within the specified −65 °C to +200 °C junction temperature limits.

Single Zener Diodes Part Context

This component belongs to the 1N5221B through 1N5252B series of Zener diodes manufactured by onsemi. The series offers a broad selection of voltages ranging from 2.4 V to 24.0 V. All devices in this family share the same 500 mW power dissipation capability and utilize the DO-204AH glass axial-lead package.

Single Zener Diodes Replacement Considerations

Other manufacturers produce equivalents under the 1N5234B designation. Verify that substitute parts meet the 6.2 V nominal voltage, 500 mW power rating, and 7 Ω impedance specifications. Ensure the replacement package matches the DO-204AH form factor for physical compatibility.
