1N5346BRL

Overview

The onsemi 1N5346BRL 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 9.1 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 surge rating capability up to 180 W for 8.3 ms pulses

Applications

• High-power stabilizing circuits
• Clipping circuits requiring robust voltage regulation
• General-purpose voltage reference applications

Procurement Notes

Verify component authenticity by checking the marking diagram for assembly location, device number, year, and work week codes. Confirm the presence of the polarity band indicating cathode orientation. Ensure the ordering suffix matches the required tape and reel specifications for automated assembly processes.

Selection Notes

Select this component when a 9.1 V regulation point is required with high power handling capabilities. The axial lead configuration supports through-hole mounting in any position. Consider the thermal resistance characteristics and derating requirements above 25°C for continuous operation scenarios.

Part Context

This part belongs to the 1N53xxB series of 5 Watt Zener diodes manufactured by onsemi. The 'R' suffix indicates the specific tape and reel packaging format containing 4000 units per reel, distinct from box packaging options available for other variants in the same family.

Replacement Considerations

The 1N5346BRLG is listed as a direct substitute for the 1N5346BRL.
