1N5350/TR8

Overview

The Microchip Technology 1N5350/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 13V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within an ambient temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 2.5 ohms, a test current of 100 mA, and a maximum reverse leakage current of 1.0 µA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification is Level 1 per IPC/JEDEC standards without requiring dry pack

Applications

• Voltage regulation in power supply circuits
• Reference voltage generation for analog circuitry
• Overvoltage protection for sensitive components

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm tolerance and compliance status. Confirm that the TR8 designation aligns with the required tape and reel packaging specifications. Ensure compatibility with existing thermal management designs given the 5W power dissipation rating. Validate component authenticity through authorized distribution channels.

Selection Notes

Select this component when a precise 13V reference with ±2% accuracy is required in a high-power application. Consider the T-18 package dimensions for board layout constraints. Evaluate thermal resistance requirements based on the intended heat sinking method. Compare against other series members if different voltage levels or looser tolerances are acceptable.

Part Context

This part belongs to the Microsemi Scottsdale Division 1N5333-5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The 'C' suffix specifically denotes the tighter ±2% voltage tolerance compared to standard B (±5%) or A (±10%) variants. These devices are designed for applications requiring robust performance under high DC currents.

Replacement Considerations

Consult official datasheets for cross-reference data. Verify electrical parameters such as Zener voltage, tolerance, and power dissipation match the original design requirements before substitution.
