1N4758CP/TR8

Single Zener Diodes Overview

The Microchip Technology 1N4758CP/TR8 is a silicon Zener diode with a nominal voltage of 56 V and a tight tolerance of ±2%. It operates in a DO-41 axial lead package, dissipating up to 1.0 W at 50°C. The device features a maximum dynamic impedance of 110 Ω and a reverse current of 5 μA at the test voltage. It withstands surge currents up to 2000 mA and functions within an operating temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a ±2% tolerance for sensitive circuitry.
• Utilizes a plastic encapsulated body offering lower thermal resistance compared to glass options.
• Capable of handling high surge currents for transient protection applications.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection networks
• Voltage regulator designs

Single Zener Diodes Procurement Notes

Verify that the component matches the specific 2% tolerance designation indicated by the 'C' suffix. Confirm the tape and reel packaging format aligns with automated assembly requirements. Ensure the manufacturer source is recognized as Microchip or its authorized predecessor entities to guarantee authenticity and traceability.

Single Zener Diodes Selection Notes

Select this part when a standard 5% tolerance is insufficient for the required circuit accuracy. The plastic construction provides better thermal performance than glass equivalents. Verify that the 110 Ω dynamic impedance meets the noise and stability requirements of the specific application environment.

Single Zener Diodes Part Context

This component belongs to the 1N4728AP through 1N4764AP series of 1-watt silicon Zener diodes. The series covers a wide voltage range from 3.3 V to 100 V. The 'P' suffix indicates a plastic molded epoxy body, while the 'TR' suffix denotes tape and reel packaging for surface mount or automated insertion processes.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N4758A (±5% tolerance) or 1N4758D (±1% tolerance). Surface mount alternatives are available in SMAJ or MLL packages. Verify that substitute components match the 56 V rating and power dissipation limits.
