1N5352BRL

Overview

The onsemi 1N5352BRL is a silicon oxide passivated junction Zener diode rated for 5 watts of steady-state power dissipation. It provides a nominal reverse Zener voltage of 15 V with a tolerance of ±5%. The device operates within a temperature range of -65°C to +200°C and features an axial lead plastic package (Case 017AA). Key electrical parameters include a maximum Zener impedance of 2.5 Ohms at the test current of 75 mA, a maximum reverse leakage current of 1 µA, and a peak forward surge rating of up to 180 W.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection.
• Features a void-free, transfer-molded thermosetting plastic case that is corrosion resistant and readily solderable.
• Includes built-in strain relief and offers high ESD protection capability per Human Body Model standards.

Applications

• Voltage regulation in general-purpose electronic circuits
• Protection against transient overvoltage events
• Reference voltage sources in power supply designs

Procurement Notes

Verify the specific ordering suffix 'BRL' corresponds to the tape and reel shipping configuration rather than bulk packaging. Confirm RoHS compliance status by checking the datasheet or manufacturer documentation, as availability may vary based on production runs. Ensure the required quantity aligns with standard reel sizes to avoid partial reel handling issues during assembly.

Selection Notes

Select this component when a precise 15 V reference is required with tight tolerance limits. Consider the thermal resistance characteristics and derating requirements above 25°C ambient temperature to ensure reliable operation under continuous load conditions. Evaluate the package dimensions for compatibility with existing board layouts and mounting positions.

Part Context

This part belongs to the 1N53 Series of Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage range from 3.3 V to 200 V, offering consistent performance across various applications. The 'B' designation indicates a ±5% voltage tolerance, while the 'R' suffix typically denotes reel packaging for automated insertion processes.

Replacement Considerations

Compatible substitutes within the same family include the 1N5352B for bulk packaging or the 1N5352BG for lead-free specifications. Cross-manufacturer equivalents such as the Microsemi MX1N5352C are available but require verification of mechanical fit and exact parameter matching before implementation.
