1N5248C-TR

Single Zener Diodes Overview

The Vishay 1N5248C-TR is a silicon planar power Zener diode with an 18 V nominal voltage and ±2 % tolerance. It operates in the DO-35 (DO-204AH) axial package, dissipating up to 500 mW at thermal equilibrium. The device features a maximum dynamic impedance of 21 Ω and a reverse leakage current of 100 nA at 14 V. It withstands junction temperatures up to 175 °C and storage ranges from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• High-precision voltage regulation with ±2 % tolerance
• Robust thermal stability for continuous operation
• Low leakage current for sensitive circuit protection

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' confirms the ±2 % tolerance requirement. Confirm the '-TR' suffix indicates tape-and-reel packaging. Ensure the DO-35 lead form matches the target PCB layout. Validate that the 500 mW dissipation rating aligns with the ambient temperature conditions of the final assembly.

Single Zener Diodes Selection Notes

Select this component when tight voltage accuracy is required compared to standard ±5 % variants. The DO-35 package provides reliable through-hole mounting. Consider the 21 Ω dynamic impedance for load regulation requirements. Verify the 175 °C junction temperature capability against the operating environment.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N5221 to 1N5267 series of small signal Zener diodes. The series covers a wide voltage range from 2.4 V to 75 V. The 'C' suffix denotes tighter manufacturing tolerances than the standard 'B' suffix. These diodes are designed for general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers' 1N5248 equivalents. Verify identical 18 V nominal voltage and ±2 % tolerance. Check for matching DO-35 package dimensions and 500 mW power dissipation ratings. Ensure dynamic impedance and leakage specifications meet or exceed the original requirements.
