1N5333BG

Single Zener Diodes Overview

The onsemi 1N5333BG is a single-channel Zener voltage regulator diode with a nominal voltage of 3.3 V and a maximum power dissipation of 5 W at 25°C. It features a ±5% tolerance, operates within a temperature range of -65°C to +200°C, and utilizes an axial lead DO-15 package for through-hole mounting.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for improved operating characteristics
• Provides high surge rating capability up to 180 W at 8.3 ms pulse width
• Features robust ESD protection rated at Class 3 exceeding 16 kV per Human Body Model

Single Zener Diodes Applications

• Voltage regulation across broad operating current and temperature ranges
• Protection against high surge stresses in electronic circuits
• General-purpose voltage reference applications requiring stable DC output

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'G' confirms the Pb-Free package status as defined by the manufacturer. Ensure the procurement documentation explicitly references the 1N5333B datasheet to confirm compliance with the specified electrical limits and mechanical dimensions for the axial lead configuration.

Single Zener Diodes Selection Notes

Select this component when a 3.3 V regulation point is required with a 5 W power handling capacity. The device is suitable for designs needing high surge withstand capability and robust ESD protection. Verify that the thermal management strategy accounts for the junction-to-lead thermal resistance under expected load conditions.

Single Zener Diodes Part Context

This part belongs to the 1N53 Series, a complete line of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage range from 3.3 V to 200 V, offering tight limits and superior capabilities due to silicon-oxide passivated junction technology housed in transfer-molded plastic packages.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5333B equivalents. Verify that any substitute matches the 3.3 V nominal voltage, 5 W power rating, and axial lead package dimensions to ensure physical and electrical compatibility.
