1N5363B

Single Zener Diodes Overview

The onsemi 1N5363B 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 30 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C ambient temperature. The device operates within a junction temperature range of -65°C to +200°C and utilizes silicon-oxide passivated junctions for superior reliability. Key electrical parameters include a test current (IZT) of 40 mA, a maximum Zener impedance (ZZT) of 8 Ω, and a reverse leakage current of 3.7 μA at 22.8 V.

Single Zener Diodes Feature Summary

• Features ESD protection rated at Class 3 (>16 kV) per the Human Body Model
• Encased in a void-free, transfer-molded thermosetting plastic package resistant to corrosion

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages
• Protection against transient overvoltage events in electronic systems
• Surge suppression applications handling peak non-repetitive currents

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix when purchasing, as it determines the packaging format. The 'G' suffix indicates a Pb-Free package. Standard box packaging contains 1000 units, while tape and reel options are available for automated assembly processes. Confirm compliance requirements such as RoHS status during the procurement phase to ensure alignment with project specifications.

Single Zener Diodes Selection Notes

Select this component based on the required 30 V regulation point and the 5 W power dissipation limit. Ensure the application environment stays within the specified -65°C to +200°C operating range. Consider the thermal resistance characteristics for heat management, particularly if derating is necessary above 25°C ambient temperature. Verify that the axial lead configuration fits the mechanical constraints of the target PCB design.

Single Zener Diodes Part Context

This part belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage range from 3.3 V to 200 V, offering consistent performance across various regulatory needs. The 1N5363B specifically addresses the 30 V segment, providing tight limits and reliable operation suitable for general-purpose industrial and commercial electronics where robust voltage clamping is essential.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include parts like the 1N5362B or 1N5364B, though these offer different nominal voltages (28 V and 33 V respectively). Cross-manufacturer equivalents must be verified against the exact electrical parameters, specifically the 30 V nominal voltage, 5 W power rating, and 8 Ω maximum impedance to ensure functional compatibility.
