1N5363A/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5363A/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, housed in an axial T-18 package and supplied in tape and reel format. It provides a nominal Zener voltage of 30V with a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 8.0 ohms at a test current of 40 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5W power dissipation
• High current applications with adequate heat sinking
• Surge protection environments

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required tolerance suffix (A for ±10%) and packaging option (TR for tape and reel). Confirm RoHS compliance status as standard versions may differ from e3 variants. Ensure thermal management design accounts for the specified junction-to-lead thermal resistance when calculating steady-state power dissipation limits.

Single Zener Diodes Selection Notes

Select this component when a 30V reference with moderate precision is needed in a high-power axial package. Compare against B suffix models for tighter tolerances or C/D suffixes for higher precision. Verify that the 5W power rating aligns with the application's thermal dissipation capabilities and that the T-18 form factor fits the mechanical constraints.

Single Zener Diodes Part Context

This component belongs to the Microsemi 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage selection from 3.3V to 200V. The 'A' suffix specifically denotes a ±10% voltage tolerance, while the 'TR' suffix indicates the tape and reel packaging configuration for automated assembly.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 5W axial Zener diodes rated at 30V with ±10% tolerance. Surface mount equivalents such as SMBJ5363A are available for space-constrained designs. Verify pinout compatibility and thermal characteristics before substitution.

Single Zener Diodes FAQ

What does the 'A' suffix indicate on the 1N5363A?

The 'A' suffix identifies the device as having a standard voltage tolerance of plus or minus 10%.

Is the 1N5363A/TR12 sensitive to electrostatic discharge?

No, the device is nonsensitive to ESD per MIL-STD-750 Method 1020.
