1N5254

Single Zener Diodes Overview

The 1N5254 is a silicon Zener diode manufactured by SMC Diode Solutions, designed for voltage regulation applications. It features a nominal Zener voltage of 27 V with a tolerance of 5% and a maximum power dissipation of 0.5 W at 25°C ambient temperature. The device utilizes a DO-35 axial glass package suitable for through-hole mounting. Key electrical characteristics include a low reverse leakage current of 5 µA at the rated voltage and a Zener impedance of 18 Ω at a test current of 9.1 mA. The component operates within a junction temperature range of -65°C to +175°C and complies with RoHS 3 standards.

Single Zener Diodes Procurement Notes

Verify the specific suffix or variant when sourcing, as standard 1N5254 parts may differ in packaging or compliance status from the G-series variants documented in public databases. Confirm that the supplier provides the official datasheet for the exact part number to ensure alignment with the 0.5 W power rating and 27 V specification. Check for RoHS 3 compliance requirements if applicable to your manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a 27 V Zener voltage is required in a small axial glass package. Ensure the circuit design accounts for the 0.5 W power dissipation limit and the thermal resistance characteristics. Compare the 18 Ω Zener impedance against application sensitivity requirements. Verify that the operating temperature range of -65°C to +175°C meets the environmental conditions of the target system.
