1N5243C-TAP

Single Zener Diodes Overview

The Vishay 1N5243C-TAP is a silicon planar power Zener diode in the DO-35 axial package. It provides a nominal Zener voltage of 13 V with a tight ±2 % tolerance, indicated by the 'C' suffix. The device dissipates up to 500 mW at thermal equilibrium and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum reverse leakage current of 0.5 µA at 9.9 V and a typical dynamic resistance of 13 Ω at a test current of 9.5 mA.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a ±2 % Zener voltage tolerance

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to ensure the required ±2 % tolerance specification is met. Confirm the 'TAP' suffix corresponds to the specific ammopack tape configuration required for your assembly line equipment. Cross-reference the document number 85588 to access the latest electrical parameters and mechanical dimensions before finalizing the design.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical, as the 'C' suffix guarantees tighter tolerances than standard variants. Ensure the application does not exceed the 500 mW power dissipation limit without adequate heat sinking. Verify that the 13 V breakdown voltage aligns with the target circuit requirements and that the DO-35 package fits the available board space.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.4 V to 75 V. The 1N5243 variant specifically targets the 13 V segment, offering stable performance for general-purpose electronic designs requiring reliable voltage clamping or reference levels.

Single Zener Diodes FAQ

What is the difference between the 1N5243B and 1N5243C?

The primary difference is the Zener voltage tolerance. The 'B' suffix indicates a standard ±5 % tolerance, while the 'C' suffix specifies a tighter ±2 % tolerance.

What is the maximum operating junction temperature?

The maximum junction temperature (Tj) is 175 °C.
