1N4752A-T

Overview

The 1N4752A-T is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 33 V with a tolerance of ±5%. The device has a maximum power dissipation of 1.3 W and operates in the DO-204AL (DO-41) axial through-hole package. Key electrical parameters include a maximum dynamic impedance of 45 Ohms and a reverse leakage current of 5 µA at 25.1 V. The forward voltage is 1.2 V at 200 mA, and it supports a junction temperature up to 175°C.

Feature Summary

• Hermetically sealed glass construction for corrosion resistance
• Compression bonded internal structure
• High temperature soldering capability

Applications

• Voltage regulation circuits
• Voltage reference applications
• Protection against overvoltage transients

Procurement Notes

Verify the specific suffix 'T' against official Vishay documentation to confirm packaging details, as standard listings often use 'TR' or 'TAP'. Ensure the component meets AEC-Q101 automotive qualification requirements if applicable to your design. Confirm RoHS compliance status directly from the manufacturer's datasheet before procurement.

Selection Notes

Select this component when a 33 V Zener voltage with ±5% tolerance is required in an axial leaded package. Consider the 1.3 W power rating and 175°C junction temperature limit for thermal management. Verify that the DO-204AL footprint matches your PCB layout constraints and that the 45 Ohm dynamic impedance fits your circuit stability requirements.

Part Context

This part belongs to the 1N47xxA series of silicon Zener diodes produced by Vishay. These devices are designed for general-purpose voltage regulation and protection. The series offers various voltage ratings within the same DO-41 package form factor, allowing for standardized inventory management across different voltage requirements in electronic designs.

Replacement Considerations

Equivalent parts include GLL4752A-E3/96 (Vishay, SMD), 1N4752A-T50A (onsemi, Through Hole), and 1N4752A (Taiwan Semiconductor, Through Hole). Verify pinout compatibility and ensure replacement components meet the same 33 V, 1.3 W, and DO-41 package specifications.
