1N5363BRL

Single Zener Diodes Overview

The onsemi 1N5363BRL is a single-channel Zener voltage regulator diode from the 1N53 Series, designed for robust voltage regulation in axial lead applications. It features a nominal Zener voltage of 30 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C. The device utilizes silicon-oxide passivated junctions within a void-free, transfer-molded plastic package (DO-201AD/Case 017AA) to ensure environmental protection. Key electrical characteristics include a test current of 40 mA, a maximum Zener impedance of 8 Ω, and a reverse leakage current of 3.7 μA. It operates reliably across a temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight parameter limits.
• Provides ESD protection rated at Class 3 (>16 kV) per the Human Body Model.
• Capable of handling high surge currents up to 180 W for 8.3 ms pulses.
• Encased in corrosion-resistant, transfer-molded thermosetting plastic suitable for various mounting positions.

Single Zener Diodes Applications

• Voltage regulation in general-purpose electronic circuits
• Protection against electrostatic discharge (ESD) events
• Surge suppression in power supply lines

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'RL' corresponds to the tape and reel packaging format containing 4000 units per reel, distinct from the box packaging associated with other suffixes like 'BG'. Confirm RoHS compliance status by checking for the '/C0071' or 'G' suffix if lead-free material is required. Ensure the specific batch matches the latest datasheet revision to account for any updates in mechanical dimensions or electrical testing conditions.

Single Zener Diodes Selection Notes

Select this component when a precise 30 V reference is needed with a 5% tolerance band. The 5 W power rating requires adequate heat sinking or lead length management to maintain performance above 25°C. Consider the axial lead form factor for through-hole mounting constraints. Evaluate the thermal resistance characteristics relative to the expected ambient temperature and duty cycle to prevent junction overheating during continuous operation.

Single Zener Diodes Part Context

This part belongs to the 1N53 Series, a comprehensive lineup of 5 Watt Zener diodes ranging from 3.3 V to 200 V. The series is characterized by JEDEC registration and standardized tolerances, ensuring compatibility with established circuit designs. The 1N5363B specifically denotes the 30 V variant within this family, sharing common mechanical and thermal properties with adjacent voltage ratings.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5363B equivalents meeting the same 30 V, 5 W, and ±5% specifications. Verify that alternative sources offer compatible axial lead dimensions (Case 017AA) and similar thermal resistance values to ensure seamless integration without redesigning the PCB footprint or heatsinking requirements.
