1N4736A-TR

Overview

The Vishay General Semiconductor - Diodes Division 1N4736A-TR is a silicon planar power Zener diode designed for voltage stabilization and clipping circuits. It features a nominal Zener voltage of 6.8 V with a standard tolerance of ±5%. The device operates in the DO-41 (DO-204AL) through-hole package, supporting a maximum power dissipation of 1.3 W at thermal equilibrium. Key electrical characteristics include a test current of 37 mA, a dynamic resistance of 3.5 Ω, and a maximum reverse leakage current of 10 µA at 4 V. It withstands junction temperatures up to 175 °C.

Feature Summary

• Utilizes silicon planar technology for robust performance in high-power stabilizing and clipping applications
• Provides precise voltage regulation with a standard Zener voltage tolerance of ±5%
• Engineered for high thermal stability with a maximum junction temperature rating of 175 °C

Applications

• Voltage stabilization circuits
• Signal clipping applications

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm packaging details. Confirm that the component meets RoHS compliance standards as defined by Vishay. Ensure the procurement specifications align with the required DO-41 package dimensions and lead spacing for your assembly process.

Selection Notes

Select this component when a 6.8 V reference or regulation point is required in through-hole designs. Consider the 1.3 W power dissipation capability and the 3.5 Ω dynamic resistance for load regulation requirements. Validate that the operating ambient temperature remains within the specified range to maintain thermal equilibrium and prevent derating issues.

Part Context

This part belongs to the 1N4728A to 1N4761A series of medium power Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of nominal voltages from 3.3 V to 75 V, all sharing similar physical package constraints and thermal characteristics within the DO-41 form factor.

Replacement Considerations

Compatible substitutes within the same series include 1N4736A-TAP. Verify pinout compatibility and ensure the replacement maintains the required 6.8 V nominal voltage and ±5% tolerance.
