1N5370E3/TR13

Overview

The Microchip Technology 1N5370E3/TR13 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333B-1N5388B series. It provides voltage regulation at a nominal Zener voltage of 51 volts with a standard tolerance of plus or minus 5 percent. The device operates within an ambient temperature range of -65°C to +150°C and features a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards. It utilizes flexible axial-lead mounting terminals and includes a tape and reel option for automated assembly.

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 suitable for various heat sinking configurations
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High surge stress protection applications
• Equipment requiring operation at elevated temperatures up to 150°C

Procurement Notes

Verify that the ordering suffix TR13 corresponds to the specified tape and reel packaging format as defined by EIA-296 standards. Confirm RoHS compliance status indicated by the e3 suffix aligns with project material requirements. Ensure procurement quantities match the manufacturer's standard factory pack sizes to avoid handling discrepancies.

Selection Notes

Select this component when a 51-volt reference with 5-percent tolerance is required. Consider the 5-watt power rating and thermal resistance characteristics for adequate heat sinking design. Evaluate the axial lead configuration against available board space and mounting constraints compared to surface mount equivalents.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series covers a wide voltage selection from 3.3 to 200 volts. The specific model utilizes the B suffix designation indicating standard voltage tolerances.

Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B series.
