1N5351B-AP

Overview

The 1N5351B-AP is a 5 W Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 14 V with a 5% tolerance. The device operates in the DO-15 axial through-hole package and supports an operating temperature range from -55 °C to +150 °C. Key electrical specifications include a maximum reverse leakage current of 1 µA, a Zener impedance of 2.5 Ω, and a test current of 100 mA.

Feature Summary

• Provides stable voltage regulation at 14 V within a 5% tolerance band for precision circuit applications.
• Features a molded plastic case with built-in strain relief and UL flammability classification rating 94V-0.
• Designed for high thermal performance with low thermal resistance, allowing operation at high DC currents with adequate heat sinking.

Applications

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

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm availability and exact electrical tolerances. Confirm RoHS compliance status as standard variants may differ. Ensure the DO-15 package dimensions match the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a 14 V regulation point is required with moderate power dissipation capabilities. The DO-15 package offers robust mechanical stability for through-hole mounting. Consider the 5% tolerance if tighter voltage accuracy is not critical for the specific application design.

Part Context

This part belongs to the 1N53xx series of 5 Watt Zener diodes produced by Micro Commercial Components. The series covers a wide voltage range from 7.5 V to 200 V, utilizing standardized JEDEC DO-15 or DO-201AE packages. The 'B' suffix typically denotes a 5% voltage tolerance, while the '-AP' indicates specific packaging or manufacturing lot variations defined by the manufacturer.

Replacement Considerations

Cross-reference with other manufacturers offering 1N5351 equivalents such as 1N5351B or 1N5351BE. Verify that replacement parts maintain the same 5 W power rating, 14 V Zener voltage, and DO-15 package footprint to ensure mechanical and electrical compatibility.
