1N5259B-TP

Single Zener Diodes Overview

The MCC 1N5259B-TP is a single Zener diode housed in a DO-35 glass axial package. It provides a nominal Zener voltage of 39 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates at a test current of 3.2 mA and dissipates up to 500 mW DC power. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 80 Ohms, and a temperature coefficient of +0.094 %/°C. It supports an operating temperature range from -55°C to +150°C.

Single Zener Diodes Feature Summary

• Utilizes a hermetically sealed glass axial leaded package for robust environmental protection.
• Features high-temperature soldering capability at 260°C for 10 seconds at terminals.
• Includes cathode band marking for polarity identification.
• Compliant with RoHS standards and exempt from lead restrictions in glass.

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference levels.
• Overvoltage protection for sensitive electronic components.
• Clipping and clamping applications in signal processing.

Single Zener Diodes Procurement Notes

Verify authenticity through authorized distributors or direct MCC channels due to counterfeiting risks. Confirm the 'B' suffix indicates ±5% tolerance and the '-TP' suffix denotes tape-and-reel packaging. Ensure compliance with specific project requirements regarding moisture sensitivity level 1 and lead-free finish specifications before integration.

Single Zener Diodes Selection Notes

Select this component when a precise 39 V reference is needed within a tight ±5% tolerance band. The DO-35 package suits through-hole designs requiring moderate power dissipation. Consider the positive temperature coefficient for thermal stability analysis. Verify that the 80 Ohm impedance meets circuit dynamic response requirements.
