1N5240B-G

Single Zener Diodes Overview

The Comchip Technology 1N5240B-G is a silicon unidirectional voltage regulator diode housed in the DO-35 glass axial leaded package. It provides a nominal Zener voltage of 10 V with a maximum power dissipation of 500 mW at 25°C ambient temperature. The device operates within a junction temperature range up to 175°C and a storage temperature range from -65°C to +175°C. Electrical characteristics include a test current of 20 mA, a maximum dynamic impedance of 17 ohms, and a maximum reverse leakage current of 5 µA.

Single Zener Diodes Feature Summary

• Unidirectional voltage regulation capability
• Cathode polarity indicated by a visible band

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source when sourcing this component, as multiple vendors produce the 1N5240B designation. Confirm RoHS compliance status directly with the supplier documentation. Ensure the DO-35 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component for designs requiring a standard 10 V reference point in through-hole assemblies. Evaluate the thermal resistance and derating curves if operating near the maximum power dissipation limit. Consider the 5% voltage tolerance when designing precision regulation loops.

Single Zener Diodes Part Context

This part belongs to the 1N5221B-G through 1N5267B-G series of axial leaded glass Zener diodes manufactured by Comchip Technology. The series covers a wide voltage range from 2.4 V to 75 V, all sharing the same DO-35 mechanical form factor and 500 mW power rating profile.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5240B parts. Verify that substitute components maintain the 10 V nominal voltage, 500 mW power rating, and DO-35 package compatibility.
