1N5340B

Single Zener Diodes Overview

The onsemi 1N5340B is a 5 Watt Zener Voltage Regulator featuring silicon-oxide passivated junctions. It provides a nominal reverse Zener voltage of 6.0 V with a ±5% tolerance, operating within a range of 5.70 V to 6.30 V at a test current of 200 mA. The device exhibits a maximum Zener impedance of 1 Ohm and a maximum reverse leakage current of 1 µA at 12.7 V. It supports a maximum DC regulator current of 790 mA and withstands surge currents up to 180 W for 8.3 ms pulses. Operating temperatures span from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for tight electrical limits and superior operating characteristics.
• Encased in a void-free, transfer-molded thermosetting plastic package offering corrosion resistance and environmental protection.
• Provides high surge capability rated up to 180 W for short-duration non-repetitive pulses.

Single Zener Diodes Applications

• Voltage regulation across broad operating current and temperature ranges
• Protection against transient overvoltage events
• Reference voltage generation in electronic circuits

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. The standard '1N5340B' designation indicates a lead-containing component. To obtain a Pb-Free package compliant with RoHS standards, confirm that the part number includes the 'G' suffix (e.g., 1N5340BG). Ensure the required packaging format, such as bulk boxes or tape and reel, matches the available options listed in the manufacturer's ordering information.

Single Zener Diodes Selection Notes

Select this component for applications requiring a precise 6 V reference with a 5 W power dissipation capacity. The ±5% tolerance suits general-purpose regulation where tighter precision is unnecessary. Consider the thermal resistance characteristics and derating requirements above 25°C to ensure the junction temperature remains within safe operating limits during continuous operation.

Single Zener Diodes Part Context

This device belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage spectrum from 3.3 V to 200 V, all sharing the same axial lead plastic package and mechanical outline. The 'B' suffix specifically denotes the standard JEDEC tolerance class of ±5% for the specified Zener voltage.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5340B equivalents. Verify that substitute components match the 6.0 V nominal voltage, 5 W power rating, DO-15/Surmetic 40 package dimensions, and ±5% tolerance specifications to maintain circuit performance.
