1N4760A

Overview

The SMC Diode Solutions 1N4760A is a unidirectional silicon voltage regulator diode designed for through-hole mounting in the DO-41 axial glass package. It features a nominal Zener voltage of 68 V with a maximum tolerance of 5%. The device supports a maximum power dissipation of 1 W and operates at a test current of 3.7 mA. Key electrical characteristics include a maximum dynamic impedance of 150 Ω, a knee impedance of 2000 Ω, and a maximum reverse leakage current of 5 µA. The component is rated for junction temperatures ranging from -55°C to 200°C.

Feature Summary

• Provides stable voltage regulation using unidirectional Zener breakdown characteristics
• Constructed with a glass encapsulation body for thermal stability
• Designed for high-temperature operation up to 200°C junction temperature

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection for low-voltage DC lines
• Clamping applications in general-purpose electronic equipment

Procurement Notes

Verify the specific manufacturer lot and compliance documentation upon receipt, as the 1N4760A designation is utilized by multiple semiconductor producers including SMC Diode Solutions, STMicroelectronics, and Fairchild. Confirm that the received components match the required DO-41 package dimensions and lead configuration. Ensure that the datasheet specifications align with your circuit's thermal and electrical requirements before integration.

Selection Notes

Select this component when a standard 68 V regulation point is required within a 1 W power budget. The DO-41 axial package facilitates easy insertion into printed circuit boards or chassis-mounted terminals. Consider the 150 Ω dynamic impedance for noise sensitivity; if lower impedance is necessary, evaluate higher-current series variants or parallel configurations to meet strict regulation standards.

Part Context

The 1N4760A belongs to the widely recognized 1N47xx series of Zener diodes, established for general-purpose voltage regulation. This series utilizes standardized JEDEC DO-41 packaging, ensuring compatibility across various legacy and modern electronic designs. SMC Diode Solutions manufactures this part to meet industry-standard electrical parameters, maintaining interoperability with other vendors' offerings in the same voltage class.

Replacement Considerations

Direct functional substitutes include the 1N4760A manufactured by STMicroelectronics, onsemi, and Taiwan Semiconductor. These parts share identical nominal voltage, power rating, and package form factor. Verify pinout orientation and thermal resistance values when substituting between different manufacturers to ensure equivalent performance in the final assembly.
