1N4701-TP

Overview

The 1N4701-TP is a 500mW silicon Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 14V with a standard tolerance of ±5%. The device operates within a junction temperature range of -65°C to +200°C and utilizes a hermetically sealed glass DO-35 axial package. Electrical characteristics include a maximum forward voltage of 1.5V at 100mA, a reverse leakage current of 0.05µA measured at 9.8V, and a maximum Zener impedance of 17.5 Ohms.

Feature Summary

• Hermetically sealed double slug type glass construction for high reliability
• Very sharp reverse characteristic for precise voltage regulation
• Standard ±5% tolerance on nominal Zener voltage

Applications

• Voltage reference circuits
• Overvoltage protection
• Clipper and clamper circuits

Procurement Notes

Verify the authenticity of the component through authorized MCC distributors or direct procurement channels to avoid counterfeit parts. Confirm that the specific ordering suffix matches the required packaging format, such as tape and reel or bulk, as these designations determine the physical supply configuration rather than altering the electrical function of the device.

Selection Notes

Select this component when a stable 14V reference is required in low-power applications. Ensure the circuit design accommodates the 500mW power dissipation limit and the specified thermal resistance. Verify that the operating environment remains within the defined junction temperature limits to maintain performance stability and prevent thermal degradation.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 500mW silicon Zener diodes produced by Micro Commercial Components. The series covers a wide voltage range from 1.8V to 43V, providing standardized options for various voltage regulation needs. All devices in this family share similar mechanical and electrical construction standards.

Replacement Considerations

Direct replacements must match the 14V nominal voltage, 500mW power rating, and DO-35 package. Cross-reference with other manufacturers' 1N4701 equivalents ensuring identical tolerance and leakage specifications are met.
