1N5365B

Single Zener Diodes Overview

The onsemi 1N5365B is a single-channel silicon voltage regulator diode with a nominal Zener voltage of 36 V and a maximum power dissipation of 5 W. It features a ±5% tolerance, a test current (IZT) of 30 mA, and a maximum Zener impedance (ZZT) of 160 Ω at IZT. The reverse leakage current is limited to 500 nA at VR = 27.4 V. Operating temperatures range from -65°C to +200°C, with a DC junction temperature limit of 150°C. It utilizes an axial lead DO-15 package.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight electrical limits.
• Features high surge capability rated up to 180 W for 8.3 ms pulses.
• Provides robust environmental protection through void-free, transfer-molded thermosetting plastic packaging.
• Includes ESD protection rated at Class 3 (>16 kV) per the Human Body Model.

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Surge protection applications
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required package type, such as 'G' for Pb-Free boxes or 'RLG' for tape and reel configurations. Confirm compliance with RoHS and REACH standards by checking the specific manufacturer documentation. Ensure the component meets the required thermal resistance and soldering temperature limits during integration.

Single Zener Diodes Selection Notes

Select this component when a 36 V reference with 5 W power handling is required. Consider the 160 Ω impedance and 500 nA leakage specifications against circuit requirements. Verify that the axial lead mounting and plastic case dimensions fit the design constraints. Evaluate thermal management needs based on the 25 °C/W junction-to-lead thermal resistance.

Single Zener Diodes Part Context

This device belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage range from 3.3 V to 200 V. All devices in the series share similar mechanical characteristics, including axial leads and corrosion-resistant finishes, designed for common environmental conditions.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers include 1N5365BG and 1N5365BRLG from onsemi. Other manufacturers produce equivalent parts under the same JEDEC designation, such as 1N5365B from Diotec Semiconductor or Micro Commercial Components.
