1SMA4758-GT3

Single Zener Diodes Overview

The 1SMA4758-GT3 is a single Zener diode manufactured by SMC Diode Solutions, designed for surface-mount applications in the DO-214AC (SMA) package. It features a nominal Zener voltage of 56 V with a tolerance of ±5% and a maximum power dissipation of 1 W. The device exhibits a maximum impedance of 110 Ohms and a reverse leakage current of 5 µA at 42.6 V. It operates within a junction temperature range of -65°C to 150°C and supports a forward voltage of 1.2 V at 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a 56 V nominal breakdown voltage
• Engineered for surface-mount assembly using the compact DO-214AC (SMA) footprint
• Capable of handling high thermal loads with a junction temperature rating up to 150°C

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 56 V levels
• Overvoltage protection stages in low-power electronic systems
• Clamping applications in signal conditioning paths

Single Zener Diodes Procurement Notes

Verify the specific suffix GT3 against procurement requirements to ensure compatibility with RoHS3 directives and REACH regulations. Confirm that the DO-214AC package dimensions align with the target PCB layout constraints. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing supply chain agreements.

Single Zener Diodes Selection Notes

Select this component when a 56 V Zener voltage is required in a surface-mount configuration. The 1 W power rating suits moderate current applications, while the ±5% tolerance ensures adequate precision for general-purpose regulation. Consider the 110 Ohm impedance limit for dynamic response requirements in clamping scenarios.

Single Zener Diodes Part Context

This component belongs to the SMA series of axial-equivalent surface-mount Zener diodes from SMC Diode Solutions. It shares the DO-214AC package form factor with other devices in the lineup but is distinguished by its specific 56 V breakdown voltage and 1 W power handling capability, differentiating it from lower or higher voltage variants.

Single Zener Diodes Replacement Considerations

Direct substitutes include equivalent 56 V, 1 W Zener diodes in the DO-214AC package from other manufacturers, provided they meet the same electrical specifications for voltage tolerance, impedance, and thermal ratings.
