1N5342BRLG

Single Zener Diodes Overview

The onsemi 1N5342BRLG is a single-channel Zener voltage regulator diode from the 1N53 Series, designed for robust performance in axial lead applications. It features a nominal Zener voltage of 6.8 V with a tolerance of ±5%. The device supports a maximum steady-state power dissipation of 5 W at a lead temperature of 25°C and operates within a junction temperature range of -65°C to +200°C. Key electrical characteristics include a test current (IZT) of 175 mA, a maximum Zener impedance (ZZT) of 1 Ω, and a maximum reverse leakage current (IR) of 10 µA.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight parameter limits.
• Encased in a void-free, transfer-molded thermosetting plastic package that provides protection against common environmental conditions.
• Offers high surge capability with a rating of up to 180 W for an 8.3 ms pulse width.

Single Zener Diodes Applications

• Voltage regulation in general-purpose electronic circuits
• Protection against transient voltage spikes and surges
• Reference voltage generation in power supply designs

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as the 'RL' suffix indicates tape and reel delivery while other suffixes may denote box quantities. Confirm RoHS compliance status and material declarations directly through official manufacturer documentation prior to integration. Ensure thermal management strategies account for the specified derating requirements above 25°C to maintain device reliability under continuous operation.

Single Zener Diodes Selection Notes

Select this component when a stable 6.8 V reference is required with high power handling capabilities. The low dynamic impedance ensures effective regulation under varying load conditions. Verify that the application's peak surge currents remain within the specified non-repetitive limits to prevent device failure. Consider the axial lead form factor for through-hole mounting requirements where mechanical stability is prioritized over compact surface-mount solutions.

Single Zener Diodes Part Context

This device belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators manufactured by onsemi. The series encompasses a wide range of breakdown voltages from 3.3 V to 200 V, all sharing similar mechanical and thermal characteristics. The 1N5342B specifically targets the lower end of this voltage spectrum, offering precise regulation suitable for sensitive analog and digital circuitry requiring stable biasing.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same family include 1N5341BRLG (6.2 V) and 1N5343BRLG (7.5 V), provided the voltage specification aligns with design requirements. Cross-brand replacements must match the 5 W power dissipation, DO-15/Surmetic 40 package dimensions, and ±5% tolerance to ensure functional equivalence without redesigning the host circuit board.
