1SMA4752A

Single Zener Diodes Overview

The NextGen Components 1SMA4752A is a surface-mount unidirectional Zener diode housed in the DO-214AC (SMA) package. It features a nominal Zener voltage of 33V with a test current of 7.5mA and a maximum dynamic impedance of 45 Ohms. The device supports a peak pulse power dissipation of 1.0W at 50°C ambient temperature, derating by 6.67mW/°C above this threshold. Maximum reverse leakage current is specified as 5μA at 25V. The component operates within a junction temperature range of -55°C to +150°C and is supplied in tape and reel packaging.

Single Zener Diodes Procurement Notes

Verify the specific part code suffix against the official specification sheet Q1030-1SMA4752AS752A to ensure correct marking codes and packaging configurations. Confirm RoHS III and REACH compliance status directly with the manufacturer prior to final procurement decisions. Request updated datasheets to validate any recent revisions or parameter changes.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 33V reference in a standard SMA footprint. Ensure thermal management accounts for the 6.67mW/°C derating factor when operating above 50°C ambient temperature. Verify that the 45 Ohm dynamic impedance meets the noise and regulation requirements of the target circuit design.

Single Zener Diodes Part Context

This device belongs to the 1SMA series of SMD Zener diodes manufactured by NextGen Components. It utilizes the JEDEC-standardized DO-214AC case outline, providing a low-profile alternative to through-hole packages while maintaining comparable power handling capabilities for general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

The specification sheet identifies MDD/1SMA4752A as a cross-reference competitor part number. Evaluate electrical compatibility and physical dimensions before substituting.
