1N5240B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5240B/TR is a silicon unidirectional Zener diode with a nominal voltage of 10V and a 5% tolerance. It operates in a hermetically sealed glass DO-35 (DO-204AH) axial-lead package. The device dissipates 0.5 watts at 25°C, with a maximum reverse current of 30µA at 7.6V and a zener impedance of 3.0 Ohms at 0.25mA. It supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction
• Inherently radiation hard design
• ESD nonsensitive per MIL-STD-750 Method 1020
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation over broad operating currents
• Temperature compensation circuits
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the suffix TR indicates tape and reel packaging per EIA-296 standards. Confirm RoHS compliance status by checking for the e3 suffix, as standard versions may contain lead. Ensure the B suffix corresponds to the required 5% voltage tolerance for your specific circuit requirements.

Single Zener Diodes Selection Notes

Select this component when a 10V reference with 5% precision is needed in a through-hole glass package. Consider the thermal resistance of 250°C/W junction-to-lead for heat dissipation calculations. Verify that the 0.5W power rating meets the steady-state requirements at your expected ambient temperature.

Single Zener Diodes Part Context
