1N5253B_T50R

Single Zener Diodes Overview

The onsemi 1N5253B-T50R is a single Zener diode designed for through-hole mounting in the DO-35-2 package. It features a nominal Zener voltage of 56 V with a 5% tolerance and a maximum power dissipation of 500 mW. The device operates within a temperature range of -65°C to +200°C, maintaining a low reverse leakage current of 100 nA and a Zener impedance of 150 Ohms at a test current of 2.2 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics in the DO-35 glass axial leaded package.
• Supports high-temperature operation up to +200°C for demanding industrial environments.
• Ensures low leakage current performance suitable for precision reference applications.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• General-purpose regulation in industrial control equipment

Single Zener Diodes Procurement Notes

Verify component authenticity against official onsemi datasheets due to end-of-life status. Confirm package integrity and pin compatibility during replacement planning. Check RoHS compliance documentation for specific manufacturing lots. Ensure storage conditions prevent moisture damage to the glass encapsulation before reflow or wave soldering processes.

Single Zener Diodes Selection Notes

Select this component when a 56 V Zener reference is required with high thermal stability. The DO-35 package suits through-hole PCB layouts. Consider the 500 mW power rating for thermal management. Verify that the 150 Ohm impedance meets circuit sensitivity requirements compared to lower impedance alternatives.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of Zener diodes manufactured by onsemi. The series offers various voltage options in the same DO-35 form factor. These components are widely used in discrete semiconductor designs for basic voltage clamping and referencing tasks across consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Check for cross-manufacturer equivalents such as those from Micro Commercial Components (MCC) or Hitachi (Renesas) offering identical 56 V, 500 mW specifications in DO-35 packages. Ensure electrical parameters match exactly before substitution.
