1N5245B_T50A

Single Zener Diodes Overview

The onsemi 1N5245B_T50A is a single-channel Zener diode with a nominal voltage of 51V and a maximum power dissipation of 500 mW. It utilizes a DO-35 through-hole package with two pins. The device features a 5% voltage tolerance, a test current of 2.5 mA, and a maximum Zener impedance of 125 Ohms. Maximum reverse leakage current is specified at 100 nA. Operating temperatures range from -65 °C to +200 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation in a standard glass axial-lead DO-35 package suitable for through-hole mounting.
• Designed for high-temperature operation with an extended junction temperature range up to +200 °C.
• Offers tight voltage tolerance for precise reference applications within the general-purpose Zener series.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify the specific suffix T50A against official datasheets to confirm tape-and-reel packaging or screening level requirements. Ensure the manufacturer designation matches onsemi specifications for the 1N5245B series. Cross-reference pinout and thermal characteristics with design constraints before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 51V regulation point is required with moderate precision. The DO-35 package supports automated insertion processes. Consider the 500 mW power rating for thermal management in enclosed environments. Verify that the 2.5 mA test current aligns with the target circuit bias conditions for optimal impedance performance.

Single Zener Diodes Part Context

This part belongs to the 1N52xxB series of 0.5 W Zener diodes manufactured by onsemi. The series provides a wide selection of voltages from 2.4 V to 200 V in standard 5% tolerances. These components are widely used in industrial and consumer electronics for basic voltage clamping and reference functions.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5245B variants in DO-35 packages. Ensure equivalent electrical parameters such as 51V nominal voltage, 500 mW power rating, and 5% tolerance are maintained during substitution.
