1N5383BRLG

Overview

The onsemi 1N5383BRLG is a single axial-lead Zener voltage regulator diode with a nominal breakdown voltage of 150 V and a maximum power dissipation of 5 W. It features a ±5% tolerance, a test current (IZT) of 8 mA, and a maximum Zener impedance (ZZT) of 330 Ω at the test current. The device exhibits a reverse leakage current of 500 nA at 114 V and a forward voltage drop of 1.2 V at 1 A. Operating within a temperature range of -65°C to +200°C, it utilizes a Case 017AA plastic package.

Feature Summary

• Utilizes silicon-oxide passivated junctions for improved operating characteristics and environmental protection.
• Provides high surge current capability rated up to 180 W for an 8.3 ms pulse width.
• Features robust ESD protection meeting Class 3 standards (>16 kV) per the Human Body Model.

Applications

• Voltage regulation across broad operating current and temperature ranges.
• Protection against transient overvoltage events in electronic circuits.
• General-purpose voltage reference applications requiring high power handling.

Procurement Notes

Verify that the specific part number suffix matches the required packaging configuration, as the 'RL' designation indicates tape and reel supply while other suffixes may denote box quantities. Confirm RoHS compliance status by checking the datasheet revision or ordering information section, as manufacturing processes and material declarations can change over time without altering the core electrical specifications.

Selection Notes

Select this component when a 150 V Zener voltage with a 5 W power rating is required for through-hole mounting. Ensure the application circuit accounts for the thermal resistance from junction to lead and derating requirements above 25°C. Verify that the expected surge currents remain within the specified non-repetitive limits defined in the datasheet graphs.

Part Context

This device belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators manufactured by onsemi. The series covers a wide voltage selection from 3.3 V to 200 V, all housed in the same axial-lead transfer-molded plastic package. The 'B' suffix specifically denotes a ±5% voltage tolerance, distinguishing it from other tolerance variants within the family.

Replacement Considerations

Cross-reference with other manufacturers offering the JEDEC registered 1N5383B specification. Verify that substitute components match the 150 V nominal voltage, 5 W power dissipation, and Case 017AA physical dimensions to ensure mechanical compatibility.
