1N5337BG

Single Zener Diodes Overview

The onsemi 1N5337BG is a silicon Zener voltage regulator diode belonging to the 1N53 Series. It provides a nominal Zener voltage of 4.7 V with a ±5% tolerance, operating within a range of 4.47 V to 4.94 V at a test current of 260 mA. The device features a maximum steady-state power dissipation of 5 W and utilizes an axial lead Surmetic 40 package (Case 017AA). It offers high surge capability up to 180 W for 8.3 ms pulses and includes an ESD rating exceeding 16 kV per the Human Body Model.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide-passivated junctions for superior electrical characteristics and environmental protection
• Features a void-free, transfer-molded thermosetting plastic case with corrosion-resistant external surfaces
• Provides robust transient protection with a peak non-repetitive surge rating of up to 180 W

Single Zener Diodes Applications

• Voltage regulation in electronic circuits requiring stable reference levels
• Protection against electrostatic discharge events in sensitive components
• Surge suppression applications handling transient energy spikes

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'G' corresponds to the Pb-Free package designation as specified in the datasheet. Confirm the specific part number matches the required JEDEC type number for the intended application. Ensure compliance with RoHS directives if applicable to the manufacturing region. Check for any specific storage or handling requirements related to moisture sensitivity levels before assembly.

Single Zener Diodes Selection Notes

Select this component when a precise 4.7 V reference is needed with tight tolerance limits. Consider the 5 W power dissipation capability and thermal resistance characteristics for heat management. Evaluate the axial lead package suitability for through-hole mounting versus surface mount alternatives. Review the temperature coefficient curves to ensure stability across the expected operating temperature range.

Single Zener Diodes Part Context

This device is part of the broader 1N5333B through 1N5388B series of 5 Watt Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, offering various tolerance options. The 1N5337BG specifically addresses the lower end of this spectrum, providing a standard voltage point for general-purpose regulation tasks.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N5337B devices meeting the same JEDEC specifications. Verify pinout compatibility and package dimensions when substituting. Ensure replacement components meet the 5 W power rating and 4.7 V nominal voltage requirements.
