1N5363B/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5363B/TR12 is a single silicon Zener diode with a nominal voltage of 30V and a ±5% tolerance. It features a T-18 axial leaded package and dissipates up to 5W at 25°C. The device operates within a temperature range of -65°C to +150°C, has a maximum dynamic impedance of 8.0 ohms, and includes a tape and reel packaging option.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile installation
• Nonsensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation over a wide operating current and temperature range
• High maximum DC current applications requiring adequate heat sinking
• Surge stress protection circuits

Single Zener Diodes Procurement Notes

Verify the exact suffix configuration against official datasheets before procurement. Confirm that the TR12 designation aligns with the required tape and reel specifications. Ensure compatibility with existing thermal management designs due to the 5W power dissipation rating. Cross-reference manufacturing origin details as product lines may transition between entities.

Single Zener Diodes Selection Notes

Select this component when a precise 30V reference with tight ±5% tolerance is required. Consider the T-18 package dimensions for board layout constraints. Evaluate thermal resistance requirements, as steady-state power drops significantly when mounted on FR4 PCBs compared to direct lead heating.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333 through 1N5388B series of 5.0-watt Zener diodes. The series covers voltages from 3.3V to 200V. The 'B' suffix specifically denotes a standard voltage tolerance of plus/minus 5%. Other suffixes like 'A', 'C', or 'D' indicate different tolerances.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5363B or SMBG5363B. RoHS compliant versions exist under the 1N5363BE3 designation.
