1N5373BRL

Overview

The onsemi 1N5373BRL is a 5 Watt Zener diode from the 1N53 Series, housed in an axial lead Surmetic 40 package (Case 017AA). It features a nominal Zener voltage of 68 V with a ±5% tolerance. The device operates within a temperature range of -65°C to +200°C and includes silicon-oxide passivated junctions for environmental protection.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics
• Provides high surge current capability up to 180 W at 8.3 ms pulse width
• Features ESD protection rated at Class 3 (>16 kV) per Human Body Model

Applications

• Voltage regulation circuits requiring 5W power dissipation
• Surge protection applications handling transient currents
• General-purpose electronic equipment operating in harsh environments

Procurement Notes

Verify the specific ordering suffix 'RL' corresponds to tape and reel packaging containing 4000 units per reel. Confirm RoHS compliance status via official documentation. Ensure the component matches the Case 017AA mechanical outline for proper mounting.

Selection Notes

Select this component for designs requiring a 68 V reference with tight electrical limits. Consider the 5W steady-state power dissipation and thermal resistance when designing heat sinking. Verify that the maximum DC Zener current aligns with circuit requirements.

Part Context

This part belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators manufactured by onsemi. The series offers a wide voltage range from 3.3 V to 200 V in an axial lead plastic package designed for robust performance across various industrial conditions.

Replacement Considerations

Compatible substitutes include other 1N5373 variants such as 1N5373BG or 1N5373BE3, provided they meet the same 68 V nominal voltage and 5W power rating specifications.
