1N5336B/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5336B/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation across a broad operating current and temperature range. It features a nominal Zener voltage of 4.3V with a ±5% tolerance, indicated by the B suffix. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial lead package. The TR12 suffix denotes tape and reel packaging compliant with EIA-296 standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation over a wide operating current and temperature range
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Constructed with a void-free transfer molded thermosetting epoxy body

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Protection of sensitive electronic components against transient voltage spikes
• Reference voltage generation in measurement and control systems

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications: 'B' indicates ±5% voltage tolerance, while 'TR12' specifies tape and reel packaging. Confirm RoHS compliance status if restricted substances are a constraint, as standard versions may differ from e3 variants. Ensure the procurement documentation aligns with the specific JEDEC registration requirements for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating and a 4.3V nominal Zener voltage are required. The T-18 axial package provides adequate thermal management for steady-state operation at high DC currents when heat sinking is applied. Consider the ±5% tolerance for general regulation tasks where tighter precision is not critical.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters. These devices are moisture classification Level 1 and do not require dry packing.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available from the same manufacturer. Military equivalent screening levels (JAN, JANTX, JANTXV) can be obtained by adding MQ, MX, or MV prefixes respectively.
