1N5342BG

Single Zener Diodes Overview

The onsemi 1N5342BG is a 5 Watt Zener voltage regulator featuring a nominal breakdown voltage of 6.8 V with a ±5% tolerance. It operates within a junction temperature range of -65°C to +200°C and utilizes an axial lead Surmetic 40 package (Case 017AA). Key electrical parameters include a maximum reverse leakage current of 10 µA, a Zener impedance of 1 Ω at the test current of 175 mA, and a forward voltage of 1.2 V maximum at 1.0 A.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection.
• Provides high surge capability rated up to 180 W for an 8.3 ms pulse width.
• Features robust ESD protection meeting Class 3 standards (>16 kV) per the Human Body Model.

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'G' corresponds to the Pb-Free package designation as defined in the manufacturer's documentation. Confirm the specific package variant matches the required mechanical dimensions for Case 017AA. Ensure compliance with RoHS directives if applicable to the target assembly process. Cross-reference the part number against the official datasheet revision history to validate parameter accuracy.

Single Zener Diodes Selection Notes

Select this component when a 5 Watt power dissipation rating is required for axial mounting applications. The 6.8 V nominal voltage and tight ±5% tolerance make it suitable for precision regulation tasks. Consider the wide operating temperature range and high surge rating for environments subject to thermal stress or transient voltage spikes.

Single Zener Diodes Part Context

This device belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators produced by onsemi. The series offers a broad voltage range from 3.3 V to 200 V, all housed in the same transfer-molded plastic axial lead package. The 1N5342B variant specifically targets the 6.8 V segment of this lineup.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include the 1N5341B (6.2 V) and 1N5343B (7.5 V), provided the voltage requirement allows adjustment. Other manufacturers producing JEDEC-compliant 1N5342 equivalents may be considered if they meet the 5 W power and axial package specifications.
