1N5361B

Single Zener Diodes Overview

The Microsemi Corporation 1N5361B is a silicon unidirectional Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 27V with a standard tolerance of ±5%. The device features a maximum power dissipation of 5.0 watts and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 5.0 ohms, a test current of 50 mA, and a maximum reverse leakage current of 0.5 µA. It utilizes an axial-lead T-18 package.

Single Zener Diodes Procurement Notes

Verify that the part number suffix matches the required tolerance and compliance specifications. Confirm the manufacturer origin, as this component is available from multiple sources including Microsemi and other distributors. Ensure the ordering suffix aligns with specific packaging or environmental requirements such as RoHS compliance or tape and reel options before finalizing procurement.

Single Zener Diodes Selection Notes

Select the 1N5361B when a precise 27V regulation point is required with a ±5% tolerance. Consider the 5-watt power dissipation capability and thermal resistance characteristics for heat sinking requirements. Evaluate the axial lead configuration against available board space and mounting constraints compared to surface mount equivalents like the SMBJ series.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of 5-watt silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3V to 200V. These devices are designed for applications requiring robust voltage regulation and high surge current handling capabilities within a standard plastic encapsulated axial-lead package.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5361B or SMBG5361B. For military screening levels, prefixes MQ, MX, or MV may be added to the base part number.
