1N4759A-T

Overview

The 1N4759A-T is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 62 V with a tolerance of ±5%. The device has a maximum power dissipation of 1.3 W and operates in the DO-41 axial through-hole package. Key electrical parameters include a reverse leakage current of 5 µA at 47.1 V, a knee impedance (Zzt) of 125 Ohms, and a forward voltage of 1.2 V at 200 mA. It supports an operating temperature range up to 175°C and holds AEC-Q101 automotive qualification.

Feature Summary

• Provides stable voltage regulation at 62 V for circuit protection applications
• Features double slug construction with metallurgically bonded die for reliability
• Supports high-temperature operation up to 175°C junction temperature
• Complies with AEC-Q101 automotive grade standards

Applications

• Voltage reference circuits requiring 62 V stability
• Overvoltage protection in automotive electronics
• Clamping applications in industrial control systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm AEC-Q101 certification status if automotive application is required. Check datasheet revisions for parameter updates. Ensure DO-41 package compatibility with existing PCB footprints. Validate thermal management requirements for 1.3 W dissipation.

Selection Notes

Select this component when a 62 V Zener voltage is specifically required. Consider the 125 Ohm knee impedance for noise-sensitive designs. Verify that the 1.3 W power rating meets thermal constraints. Compare against alternative manufacturers if supply chain diversification is needed. Ensure lead-free compliance matches environmental regulations.

Part Context

This part belongs to the 1N47xx series of glass-passivated Zener diodes from Vishay. These components are designed for general-purpose voltage regulation and clamping. The DO-41 package offers robust mechanical strength for through-hole mounting. The series covers a wide voltage range from 2.4 V to 200 V.

Replacement Considerations

Direct substitute: 1N4759A-TR (Vishay General Semiconductor - Diodes Division). Verify pinout and package dimensions match before integration.
