1N5351BRL

Overview

The onsemi 1N5351BRL is a 5 Watt Zener diode from the Surmetic 40 series, housed in an axial lead DO-201AE (Case 017AA) plastic package. It features a nominal Zener voltage of 14 V with a ±5% tolerance and a test current of 100 mA. The device guarantees a maximum Zener impedance of 2.5 Ω at the test current and 75 Ω at the knee current. It operates within a temperature range of -65°C to +200°C and supports a maximum non-repetitive surge current of 1 A.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection.
• Features a void-free, transfer-molded thermosetting plastic case that is corrosion resistant.
• Provides high ESD protection rated at Class 3 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 the specific ordering suffix 'RL' corresponds to the tape and reel shipping configuration as defined in the official datasheet. Confirm that the component meets all required electrical parameters for your application, particularly the Zener voltage tolerance and thermal dissipation limits under your specific mounting conditions.

Selection Notes

Select this component when a 5 Watt power rating and a 14 V nominal breakdown voltage are required. Ensure the circuit design accommodates the specified thermal resistance and derating requirements above 25°C. Verify compatibility with the axial lead package dimensions for the intended PCB layout or chassis mounting.

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, offering tight limits and improved characteristics due to silicon-oxide passivation technology. These devices are designed for robust performance in common environmental conditions.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5351B variants meeting the same JEDEC specifications. Cross-reference with parts like 1N5351BE or generic 1N5351B equivalents, ensuring they match the 14 V nominal voltage, 5 W power rating, and DO-201AE package form factor.
