1N5241B

Single Zener Diodes Overview

The onsemi 1N5241B is a single silicon Zener diode housed in an axial lead glass package (DO-35). It provides a nominal Zener voltage of 11.0 V with a tolerance range of 10.450 V to 11.550 V at a test current of 20 mA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +200°C. Key electrical characteristics include a maximum dynamic impedance of 22 Ω, a maximum reverse leakage current of 2 µA at 8.4 V, and a positive voltage temperature coefficient of 0.076 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental stability
• Positive voltage temperature coefficient suitable for stable regulation above 5V
• Lead-free and halide-free compliant packaging

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• General-purpose rectification and clamping

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm shipping format. Standard bulk bags contain 5000 units per bag, while tape and reel options are available for automated assembly processes. Ensure the selected variant matches the required mechanical and packaging specifications for the intended production line.

Single Zener Diodes Selection Notes

Select this component when a precise 11 V reference or clamp is required in through-hole designs. The 500 mW power rating allows for moderate current handling, while the wide operating temperature range ensures reliability in demanding thermal environments. Verify that the 22 Ω dynamic impedance meets the noise and ripple requirements of the target application.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5252B series of general-purpose Zener diodes manufactured by onsemi. The series covers a broad voltage spectrum from 2.2 V to 24 V, utilizing a consistent DO-35 axial lead glass package across all variants. This standardization simplifies inventory management for designers requiring multiple voltage levels.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5241B equivalents to ensure pinout compatibility and matching electrical tolerances. Verify that substitute parts meet the same 500 mW power dissipation and hermetic sealing standards if environmental resistance is critical.
