1N5374BRL

Overview

The onsemi 1N5374BRL is a silicon Zener diode from the 1N53 Series, designed for voltage regulation in axial lead packages. It features a nominal Zener voltage of 75 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. Key electrical parameters include a reverse leakage current of 0.5 µA at 56 V, a maximum Zener impedance of 45 Ω at a test current of 20 mA, and a maximum DC Zener current of 63 mA.

Feature Summary

• Utilizes silicon-oxide passivated junctions for tight limits and superior operating characteristics.
• Provides protection against common environmental conditions through void-free, transfer-molded plastic packaging.
• Features an ESD rating of Class 3 (>16 kV) per the Human Body Model.
• Capable of handling surge currents up to 180 W for 8.3 ms pulses.

Applications

• Voltage regulation circuits requiring stable reference voltages.
• Protection against transient overvoltage events in electronic systems.
• Power supply designs utilizing high-power axial lead components.

Procurement Notes

Verify that the ordering suffix 'BRL' corresponds to the tape and reel packaging format specified in the datasheet. Confirm RoHS compliance status by checking for the 'G' suffix or specific package markings, as standard versions may differ. Ensure the required quantity aligns with the 4000-unit reel specification provided for this variant.

Selection Notes

Select this component when a 75 V regulation point is required with a 5 W power handling capability. The axial lead configuration suits through-hole mounting applications where robust mechanical stability is needed. Consider the thermal resistance characteristics and derating requirements above 25°C to ensure reliable operation under continuous load conditions.

Part Context

This part belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage range from 3.3 V to 200 V, offering various tolerances identified by suffix letters. The 1N5374B specifically denotes the 75 V nominal voltage variant with ±5% tolerance.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5374B variants. Verify that replacement parts match the 75 V Zener voltage, 5 W power rating, and DO-201/axial lead package dimensions to ensure physical and electrical compatibility.
