1N5383BG

Overview

The onsemi 1N5383BG is a silicon-oxide passivated junction Zener voltage regulator diode with a nominal reverse voltage of 150 V and a ±5% tolerance. It operates within the 1N53 Series, providing a steady-state power dissipation of 5 W in an axial lead Surmetic 40 (CASE 017AA) plastic package. The device features a maximum junction-to-lead thermal resistance of 25 °C/W and withstands surge currents up to 180 A for 8.3 ms pulses. It offers an ESD rating exceeding 16 kV per the Human Body Model and includes Pb-Free packaging options.

Feature Summary

• Utilizes silicon-oxide passivated junction technology for tight electrical limits and superior operating characteristics.
• Provides robust transient protection with a surge rating of up to 180 W at 8.3 ms pulse width.
• Features high electrostatic discharge immunity rated at Class 3 (>16 kV) under the Human Body Model.
• Encased in a void-free, transfer-molded thermosetting plastic package resistant to common environmental conditions.

Applications

• Voltage regulation across broad operating current and temperature ranges
• Protection against transient overvoltage events in electronic circuits
• Reference voltage generation in power supply designs

Procurement Notes

Verify that the ordering suffix 'G' corresponds to the Pb-Free package configuration as defined in the datasheet. Confirm the specific JEDEC type number matches the required nominal voltage and tolerance specifications. Ensure compliance with RoHS directives if lead-free materials are mandatory for the intended application environment.

Selection Notes

Select this component when a precise 150 V regulation point is required with a standard ±5% tolerance. The 5 W power rating necessitates adequate heat sinking or PCB copper area to maintain junction temperatures below 150°C during continuous DC operation. Consider the axial lead form factor for through-hole mounting requirements.

Part Context

This part belongs to the 1N5333B through 1N5388B series of 5 Watt Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, utilizing a consistent Surmetic 40 package design. The 'B' designation indicates a ±5% voltage tolerance, while the 'G' suffix denotes availability in Pb-Free packaging.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N5383B specification. Verify that substitute components match the 150 V nominal voltage, ±5% tolerance, 5 W power dissipation, and axial lead package dimensions to ensure mechanical and electrical compatibility.
