1N5362B

Single Zener Diodes Overview

The Microsemi Corporation 1N5362B is a silicon unidirectional voltage regulator diode with a nominal Zener voltage of 28 V. It belongs to the JEDEC registered 1N5333-5388B series and features a maximum power dissipation of 5.0 watts at 25 °C. The device operates within a temperature range of -65 °C to +150 °C and utilizes a T-18 axial-lead plastic package. Electrical characteristics include a test current (IZT) of 50 mA, a maximum dynamic impedance (ZZ) of 6.0 Ω, and a maximum reverse current (IR) of 0.5 µA. Standard voltage tolerance for the B suffix is ±5%.

Single Zener Diodes Feature Summary

• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Withstands high surge stresses while maintaining minimal changes in voltage versus current
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 flammability classification

Single Zener Diodes Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against high surge stresses
• General-purpose voltage reference applications in industrial environments

Single Zener Diodes Procurement Notes

Verify that the ordering prefix matches the required screening level, such as MX for military equivalent screening, or e3 for RoHS compliance. Confirm the specific suffix corresponds to the desired voltage tolerance, where B indicates ±5%. Ensure the package type aligns with the T-18 axial lead specification. Cross-reference datasheet revision D for accurate electrical parameters before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 28 V regulation point is required with a 5-watt power handling capability. Consider the low thermal resistance design if operation at high maximum DC currents is necessary with adequate heat sinking. Evaluate the wide selection of available voltages from 3.3 V to 200 V within the same series for system standardization. Verify moisture classification Level 1 requirements to determine if dry pack storage is unnecessary.

Single Zener Diodes Part Context

This part is part of the Microsemi Scottsdale Division 1N5333B thru 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide voltage selection from 3.3 V to 200 V with various tolerance options identified by suffix letters. These plastic encapsulated devices are designed for applications requiring reliable voltage regulation over broad operating conditions.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. For higher reliability requirements, screened versions can be obtained by adding prefixes such as MQ, MX, or MV to the base part number.
