1N5245B-G

Single Zener Diodes Overview

The Comchip Technology 1N5245B-G is a silicon unidirectional voltage regulator diode housed in the DO-35 glass axial leaded package. It provides a nominal Zener voltage of 15 V with a maximum power dissipation of 0.5 W 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 7.8 mA, a maximum dynamic impedance of 16 Ω, and a maximum reverse leakage current of 0.1 μA at 21 V.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single PN junction structure
• Features polarity indication via a cathode band on the glass case
• Designed for thermal equilibrium DC measurements

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as multiple vendors produce components under this standard part number. Confirm that the received unit matches the DO-35 glass package dimensions and includes the required cathode band marking. Ensure compliance with RoHS requirements if applicable to the assembly process.

Single Zener Diodes Selection Notes

Select this component for designs requiring a fixed 15 V reference point in low-power environments. The DO-35 through-hole package facilitates manual insertion or wave soldering processes. Consider the positive temperature coefficient above 5 V when designing for wide thermal operating ranges.

Single Zener Diodes Part Context

This component belongs to the 1N5221B-G through 1N5267B-G series of axial leaded glass Zener diodes manufactured by Comchip Technology. The series covers a voltage range from 2.4 V to 75 V, all sharing the same 0.5 W power dissipation rating and standardized mechanical footprint.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5245B parts. Verify that substitute components maintain the DO-35 package outline and meet the 15 V nominal voltage specification.
