1N5347BRL

Overview

The onsemi 1N5347BRLG is a 5 W Zener voltage regulator diode housed in an axial lead Surmetic 40 package. It provides a nominal Zener voltage of 10 V with a ±5% tolerance, tested at a current of 125 mA. The device features a maximum Zener impedance of 2 Ω and a reverse leakage current of 5 µA at 7.6 V. It operates within a junction temperature range of -65°C to +200°C and withstands surge currents up to 180 W for 8.3 ms pulses.

Feature Summary

• Utilizes silicon-oxide passivated junction technology for superior operating characteristics
• Offers high surge rating capability of up to 180 W at 8.3 ms pulse width
• Provides robust ESD protection rated at Class 3 (>16 kV) per the Human Body Model

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Procurement Notes

Verify that the ordering suffix matches the required packaging format, as 'RL' indicates tape and reel delivery while other suffixes may denote box quantities. Confirm RoHS compliance status if environmental regulations apply to your specific manufacturing process. Ensure the component marking aligns with the datasheet specifications for quality assurance during incoming inspection.

Selection Notes

Select this component when a precise 10 V reference is required with tight tolerance limits. Consider the thermal resistance characteristics and derating requirements above 25°C to ensure reliable operation under steady-state conditions. Evaluate the package's mechanical strength and solderability for through-hole mounting applications.

Part Context

This part belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators from onsemi. The series covers a wide Zener voltage range from 3.3 V to 200 V, all utilizing the same Surmetic 40 axial lead plastic package. The 'B' designation indicates a ±5% tolerance, distinguishing it from wider tolerance variants.

Replacement Considerations

Cross-reference with other manufacturers offering the standard 1N5347B specification. Verify that substitute parts meet the identical 5 W power dissipation, 10 V nominal voltage, and ±5% tolerance requirements. Ensure the replacement package maintains the same axial lead dimensions for board compatibility.
