BAW62_T50R

Overview

The onsemi BAW62_T50R is a single silicon junction diode designed for general-purpose switching applications. It features a nominal Zener voltage of 39V and a maximum power dissipation of 500 mW. The component utilizes a DO-35 through-hole package with two pins. Key electrical parameters include a Zener voltage tolerance of 5%, a test current of 2.5 mA, and a maximum Zener impedance of 125 Ω. The device supports an operating temperature range from -65 °C to +200 °C.

Feature Summary

• Single-channel configuration for dedicated circuit protection or reference tasks
• High thermal stability enabling operation in extreme temperature environments
• Through-hole mounting compatibility for standard PCB layouts

Applications

• Voltage regulation in low-power circuits
• Overvoltage protection for sensitive components
• Reference voltage generation in analog signal processing

Procurement Notes

Verify the specific suffix T50R against official datasheets to confirm packaging and tape-and-reel specifications. Ensure compliance with RoHS directives by checking material composition declarations. Confirm that the DO-35 package dimensions match your board space requirements. Validate the 5% Zener voltage tolerance meets your circuit design margins before finalizing procurement.

Selection Notes

Select this component when a stable 39V reference is required in a through-hole assembly. Consider the 500 mW power rating for thermal management in enclosed spaces. The wide operating temperature range makes it suitable for industrial or automotive environments where standard commercial parts may fail. Verify that the 125 Ω impedance does not impact signal integrity in high-speed applications.

Part Context

This part belongs to onsemi's line of general-purpose Zener diodes. It shares the DO-35 form factor with other axial-lead devices but is distinct due to its specific 39V breakdown voltage. It serves as a fundamental passive component for stabilizing voltages in discrete transistor circuits and power supply feedback loops.

Replacement Considerations

Check for direct equivalents with identical 39V Zener voltage and DO-35 package. Verify that substitute parts meet the same 500 mW power dissipation and -65 °C to +200 °C temperature range. Ensure impedance and leakage current specifications are compatible with the original design constraints.
