1N5350BG

Overview

The onsemi 1N5350BG is a silicon-oxide passivated junction Zener voltage regulator diode belonging to the 1N53 Series. It provides a nominal reverse Zener voltage of 13 V with a tolerance of ±5%. The device operates in an axial lead, transfer-molded plastic package (Surmetic 40) and supports a maximum steady-state power dissipation of 5 W at a lead temperature of 25°C. It features a high surge rating of up to 180 W for 8.3 ms pulses and offers robust ESD protection rated at Class 3 (>16 kV) per the Human Body Model.

Feature Summary

• Utilizes silicon-oxide passivated junctions for tight electrical limits and superior operating characteristics
• Features a void-free, transfer-molded thermosetting plastic case that resists corrosion and common environmental conditions
• Provides high surge current capability and withstands significant transient stresses
• Includes built-in strain relief and flexible axial-lead mounting terminals

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

Procurement Notes

Verify the specific ordering suffix 'G' confirms the Pb-Free package status as defined by the manufacturer. Ensure the procurement documentation references the correct JEDEC registered part number 1N5350B. Confirm compliance with RoHS directives if required for the target application environment. Cross-reference the mechanical outline CASE 017AA to ensure physical compatibility with existing board layouts.

Selection Notes

Select this component when a 13 V Zener voltage with ±5% tolerance is required for power dissipation up to 5 W. Consider the axial lead Surmetic 40 package for through-hole mounting applications where high thermal resistance and robust mechanical stability are necessary. Evaluate the 180 W surge rating for circuits exposed to transient overvoltages or high inrush currents.

Part Context

This device is part of the comprehensive 1N5333B through 1N5388B series, which covers a wide selection of Zener voltages from 3.3 V to 200 V. All members of this series share the same Surmetic 40 axial lead package and utilize silicon-oxide passivation technology. The series is designed to offer consistent performance characteristics and environmental protection across various voltage ratings.

Replacement Considerations

Compatible replacements include other manufacturers' versions of the 1N5350B within the 1N53 Series. Verify that substitute components maintain the 5 W power dissipation rating, ±5% voltage tolerance, and compatible axial lead dimensions.
