1N5241BTR

Single Zener Diodes Overview

The Fairchild Semiconductor 1N5241BTR is a silicon unidirectional Zener diode housed in the DO-35 axial through-hole package. It features a nominal Zener voltage of 11 V with a tolerance of ±5%. The device has a maximum power dissipation of 0.5 W and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a test current of 20 mA, a maximum reverse leakage current of 2.0 µA at 8.4 V, and a dynamic impedance of 11 Ohms.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via Zener breakdown mechanism
• Utilizes glass encapsulation for thermal stability and environmental protection
• Designed for high junction temperature operation up to 200°C

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'BTR' corresponds to the reel packaging format specified by Fairchild Semiconductor or onsemi. Confirm the component is sourced from authorized distributors to ensure authenticity. Check RoHS compliance status as manufacturing origins may vary. Ensure the DO-35 package dimensions match the design requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when an 11 V regulation point is required with tight ±5% tolerance. The DO-35 package suits through-hole designs needing robust mechanical mounting. Consider the 0.5 W power rating and 11 Ohm dynamic impedance for circuit stability. Verify that the operating temperature range meets the specific application environment constraints.

Single Zener Diodes Part Context

The 1N5241B belongs to the standard Zener diode series manufactured by Fairchild Semiconductor, now part of onsemi. This series provides reliable voltage regulation for general-purpose electronics. The 'B' suffix indicates the ±5% voltage tolerance class, distinguishing it from wider tolerance variants. The component is widely used in power supplies and signal conditioning circuits.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5241B from other manufacturers such as Rectron or LGE. Verify pinout compatibility and package dimensions (DO-35) for direct substitution. Ensure replacement components meet the same 11 V nominal voltage and 0.5 W power dissipation ratings.
