AZ574ZTR-E1

Overview

The AZ574ZTR-E1 is a monolithic integrated voltage stabilizer designed for TV tuners, manufactured by BCD Semiconductor. It provides a typical reference voltage of 33V with a maximum cathode voltage of 35V. The device operates within an ambient temperature range of -20°C to 75°C and supports a recommended operating cathode current up to 30mA. Electrical characteristics include a dynamic impedance of 5Ω to 12Ω at 1kHz and a temperature drift of 0.6mV/°C. Power dissipation is rated at 700mW at 75°C.

Feature Summary

• Low temperature coefficient ensures stable output across the operating range
• Low dynamic impedance minimizes load fluctuation effects
• High cathode current capacity supports demanding tuner loads

Applications

• TV Tuners

Procurement Notes

Verify the manufacturer designation on the datasheet as BCD Semiconductor Manufacturing Limited. Confirm that the E1 suffix indicates lead-free compliance and RoHS adherence. Ensure the TR suffix corresponds to the specified Ammo packing type rather than bulk packaging when sourcing this specific variant.

Selection Notes

Select this component for applications requiring a precise 33V reference in television tuner circuits. Verify that the required cathode current remains within the 30mA operational limit. Check that the operating environment stays within the -20°C to 75°C temperature range to maintain specified electrical performance.

Part Context

This part belongs to the AZ574 series of high-precision voltage references. It utilizes a TO-92-2 package configuration. The product line includes variations distinguished by ordering suffixes such as Z for the package type, E1 for lead-free status, and TR for the Ammo packing method.

Replacement Considerations

Cross-reference with other AZ574 variants like AZ574Z-E1 or AZ574Z-G1 if different packaging or environmental certifications are required.
