1N5337BRL

Single Zener Diodes Overview

The onsemi 1N5337BRL is a single-channel Zener voltage regulator diode from the 1N53 Series. It features a nominal Zener voltage of 4.7 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C. The device operates within a junction temperature range of -65°C to +200°C and utilizes an axial lead DO-15 (CASE 017AA) package. Electrical characteristics include a test current of 260 mA, a maximum Zener impedance of 2 Ω, and a maximum reverse leakage current of 5 μA.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight parameter limits.
• Provides robust surge protection with a rating of up to 180 W at 8.3 ms pulse width.
• Offers high electrostatic discharge (ESD) immunity rated at Class 3 (>16 kV) per the Human Body Model.
• Features void-free, transfer-molded thermosetting plastic packaging that ensures corrosion resistance and solderability.

Single Zener Diodes Applications

• Voltage regulation in circuits requiring stable reference voltages across broad operating currents.
• Protection against transient overvoltage events and electrical surges.
• General-purpose voltage clamping and regulation tasks in industrial environments.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'BRL' corresponds to the required tape and reel packaging configuration, as this variant differs from standard box quantities. Confirm RoHS compliance status by checking for the 'G' suffix if lead-free material is mandatory for the assembly process. Ensure the procurement documentation explicitly references the 1N5337B part number to match the specified 4.7 V nominal voltage and 5 W power rating.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V regulated output is required with a 5 W power handling capability. The axial lead format is suitable for through-hole mounting applications where mechanical stability is needed. Consider the thermal resistance characteristics and derating requirements above 25°C to ensure the junction temperature remains within the specified operational limits during continuous operation.

Single Zener Diodes Part Context

This component belongs to the 1N53 Series of Surmetic 40 Zener Voltage Regulators manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, all housed in the same axial lead plastic package. The 1N5337B specifically denotes the 4.7 V nominal voltage variant within this family, designed for general-purpose regulation and surge protection applications.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5337B or 1N5337BG devices. Verify that replacement parts maintain the same 4.7 V nominal voltage, 5 W power dissipation, and DO-15 axial lead package dimensions to ensure mechanical and electrical compatibility without circuit redesign.
