1N5346BRLG

Overview

The onsemi 1N5346BRLG is a silicon-oxide passivated junction Zener voltage regulator diode from the 1N53 Series. It provides a nominal reverse Zener voltage of 9.1 V with a tolerance of ±5%. The device features a maximum steady-state power dissipation of 5 W and operates within a temperature range of -65°C to +200°C. Packaged in an axial lead Surmetic 40 (Case 017AA) plastic housing, it includes a Pb-Free designation indicated by the 'G' suffix.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection.
• Features a void-free, transfer-molded thermosetting plastic package with corrosion-resistant external surfaces.
• Includes built-in strain relief and offers high surge current ratings up to 180 W at 8.3 ms pulse width.

Applications

• Voltage regulation in electronic circuits requiring stable reference voltages.
• Protection against overvoltage conditions in power supply systems.
• Clamping applications for transient voltage suppression.

Procurement Notes

Verify that the ordering suffix matches the required packaging format, as the RL suffix denotes tape and reel shipping while G indicates Pb-Free compliance. Confirm RoHS status and specific electrical tolerances against the manufacturer's datasheet before finalizing procurement orders to ensure compatibility with design specifications.

Selection Notes

Select this component when a 9.1 V Zener voltage with tight ±5% tolerance is required for high-power applications. Ensure the circuit design accommodates the 5 W power dissipation limit and verify thermal management strategies are adequate for the specified operating temperature range. Consider the axial lead configuration for through-hole mounting requirements.

Part Context

This part belongs to the 1N53xxB series of 5 Watt Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, utilizing JEDEC registered type numbers. The 1N5346B variant specifically targets the 9.1 V segment, offering reliable performance in industrial and commercial electronics environments.

Replacement Considerations

Direct substitutes include other manufacturers' 1N5346B variants or equivalent parts from the same 1N53 series family. Verify pinout compatibility and thermal resistance characteristics when replacing with components from different suppliers to maintain circuit integrity.
