1N961BTR

Single Zener Diodes Overview

The 1N961BTR is a single silicon planar power Zener diode manufactured by onsemi. It features a nominal Zener voltage of 10 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW and operates in the through-hole DO-35 axial package. Key electrical parameters include a maximum reverse leakage current of 25 µA, a Zener impedance of 7.5 Ohms, and a test current of 14 mA. The component supports a wide operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust performance
• Provides standard Zener voltage tolerance of ±5%
• Designed for high-temperature operation up to 200°C

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the part number appears associated with both onsemi and Fairchild Semiconductor in public records. Confirm the package type is DO-35 and the suffix TR indicates tape and reel packaging. Ensure the voltage rating matches the 10 V specification required for your design. Check for any RoHS compliance documentation relevant to the production batch.

Single Zener Diodes Selection Notes

Select this component when a stable 10 V reference is needed in a compact axial package. The 500 mW power rating suits low-to-medium current applications. Consider the ±5% tolerance if tighter precision is not critical. The wide thermal range allows use in harsh environments where standard components might fail.

Single Zener Diodes Part Context

This part belongs to the family of general-purpose Zener diodes used for voltage clamping and regulation. Similar parts in the series include the 1N960B (9.1 V) and 1N962B (11 V), offering different voltage options within the same power and package constraints. These diodes are commonly found in consumer electronics and industrial control boards.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N961B variants in DO-35 packages. Verify that replacement parts maintain the 10 V Zener voltage, 500 mW power rating, and ±5% tolerance. Ensure the replacement also supports the required operating temperature range.
