1N5374BRLG

Overview

The onsemi 1N5374BRLG is a 5 Watt Zener voltage regulator diode from the 1N53 Series, housed in an axial lead Surmetic 40 package (Case 017AA). It features a nominal Zener voltage of 75 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

• Surplus power dissipation capability up to 180 W during 8.3 ms surge events
• ESD protection rated at Class 3 (>16 kV) per Human Body Model
• Silicon-oxide passivated junctions ensure superior operating characteristics

Applications

• Voltage regulation circuits requiring high surge current handling
• Power supply protection against transient overvoltage conditions
• Industrial equipment utilizing robust axial lead components

Procurement Notes

Verify that the ordering suffix 'RLG' corresponds to the tape and reel packaging configuration specified in the datasheet. Confirm RoHS compliance status as indicated by the 'G' suffix. Ensure the component matches the Case 017AA mechanical outline dimensions before integration into the design.

Selection Notes

Select this component when a 75 V reference with tight electrical limits is required. The B-suffix guarantees specific parameters including maximum impedance and leakage current. Consider the thermal resistance characteristics and derating requirements above 25°C ambient temperature for proper heat management.

Part Context

This part belongs to the 1N53 Series of 5 Watt Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V. The 1N5374B variant specifically targets applications needing precise 75 V regulation with enhanced reliability compared to standard commercial grade parts.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5374B equivalents. Verify that replacement parts meet the same 5 W power rating, 75 V nominal voltage, and DO-15/Case 017AA package dimensions.
