1N5348BRLG

Overview

The onsemi 1N5348BRLG is a single-channel Zener voltage regulator diode from the 1N53 Series, housed in an axial lead DO-15 (Surmetic 40) package. It features a nominal Zener voltage of 11 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 includes silicon-oxide passivated junctions for environmental protection.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection
• Provides tight electrical limits guaranteed across multiple parameters including impedance and leakage current
• Features high surge capability rated up to 180 W for 8.3 ms pulses
• Offers robust ESD protection meeting Class 3 standards (>16 kV) per the Human Body Model

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 'RLG' corresponds to the specific tape and reel packaging configuration containing 4000 units per reel as defined in the manufacturer's documentation. Confirm compliance requirements such as RoHS status directly through official datasheets or product change notices, as these attributes are subject to revision by the manufacturer.

Selection Notes

Select this component when a precise 11 V regulation point is required with a 5 W thermal handling capacity. Ensure the application environment supports the specified -65°C to +200°C operating range. Verify that the circuit design accommodates the maximum DC Zener current of 430 mA without exceeding the thermal resistance limits defined for the Surmetic 40 package.

Part Context

This part belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators manufactured by onsemi. The series covers a wide Zener voltage range from 3.3 V to 200 V, all sharing the same mechanical Surmetic 40 axial lead package. The 'B' designation indicates a ±5% voltage tolerance, while the 'RLG' suffix specifies the reel packaging format.

Replacement Considerations

Cross-reference other manufacturers offering the 1N5348B specification in a DO-15 package. Verify that any substitute matches the 11 V nominal voltage, 5 W power rating, and ±5% tolerance to ensure functional equivalence in existing designs.
