1N5355BRLG

Overview

The onsemi 1N5355BRLG is a single-channel Zener voltage regulator diode from the 1N53 Series, designed for axial lead mounting in a Case 017AA plastic package. It features a nominal reverse Zener voltage of 18 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at a lead temperature of 25°C. The device operates within a junction and storage temperature range of -65°C to +200°C. Key electrical characteristics include a test current (IZT) of 65 mA, a maximum Zener impedance (ZZT) of 2.5 Ω, and a maximum reverse leakage current of 500 nA at 13.7 V.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight parameter limits.
• Features void-free, transfer-molded thermosetting plastic construction providing corrosion resistance and environmental protection.
• Offers high surge capability with ratings up to 180 W for an 8.3 ms pulse width.
• Includes ESD protection rated at Class 3 (>16 kV) per the Human Body Model.

Applications

• Voltage regulation circuits requiring stable reference voltages.
• Protection against transient overvoltage events in electronic systems.
• General-purpose clamping applications in industrial environments.

Procurement Notes

Verify that the ordering suffix RLG corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm compliance with RoHS directives and REACH regulations as indicated in the manufacturer's documentation. Ensure the component meets the specified thermal management requirements for the intended application environment.

Selection Notes

Select this component when a precise 18 V regulation point is needed with a 5 W power handling capacity. Consider the axial lead format for through-hole mounting or specific board layout constraints. Evaluate the thermal resistance characteristics to ensure adequate heat dissipation under continuous DC load conditions.

Part Context

This part belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators manufactured by onsemi. The series covers a wide Zener voltage range from 3.3 V to 200 V, offering consistent performance across various voltage levels using the same axial lead package design.

Replacement Considerations

Compatible substitutes within the same series include the 1N5354B and 1N5356B, which share identical mechanical and thermal specifications but differ in nominal Zener voltage values.
