1N5337BE3/TR13

Single Zener Diodes Overview

The Microsemi Corporation 1N5337BE3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B-1N5388B series, housed in an axial T-18 package with tape and reel packaging. It provides a nominal Zener voltage of 4.7 V at a test current of 260 mA, featuring a standard tolerance of ±5% indicated by the B suffix. The device exhibits a maximum dynamic impedance of 2.0 ohms and a maximum reverse leakage current of 5 µA at 1.0 V. It operates within a temperature range of -65°C to +150°C and includes RoHS compliance via the e3 suffix.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes against official documentation to confirm exact electrical tolerances and packaging configurations. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure thermal management strategies align with the specified power dissipation ratings and derating curves provided in the datasheet.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 4.7 V reference with ±5% tolerance and 5 W power handling capability. Consider the axial lead configuration for through-hole mounting or tape and reel availability for automated assembly processes. Evaluate thermal resistance characteristics and heat sinking requirements to ensure operation remains within the specified junction-to-ambient limits under steady-state conditions.
