UPC1093T-E1-AZ

Overview

The UPC1093T-E1-AZ is a high-precision adjustable shunt voltage reference IC manufactured by Renesas Electronics. It operates within a supply voltage range of 2.495 V to 36 V and provides an initial accuracy of ±2%. The device features a temperature coefficient of 100 ppm/°C and supports a maximum shunt current of 100 mA. It is designed for surface mount technology (SMD/SMT) installation in an SOT-89-3 package. The operational temperature range spans from -20°C to +85°C, ensuring reliable performance in standard industrial environments.

Feature Summary

• Adjustable output voltage capability across a wide input range
• High precision with defined initial accuracy and low temperature drift
• Compact surface-mount packaging for automated assembly

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Portable battery-powered instrumentation requiring stable references
• Industrial process control systems needing accurate voltage regulation

Procurement Notes

Verify the specific suffix codes against the official datasheet to ensure correct pinout and electrical characteristics. Confirm RoHS compliance status and lead times directly with authorized distributors. Check for end-of-life notices or alternative recommendations from Renesas before finalizing procurement plans.

Selection Notes

Select this component when a compact, adjustable shunt regulator is required for space-constrained designs. Ensure the application voltage does not exceed the 36 V maximum rating. Consider the ±2% initial accuracy and 100 ppm/°C temperature coefficient against system tolerance requirements.

Part Context

This part belongs to the UPC1093 series of shunt regulators, which are designed as drop-in replacements for traditional Zener diodes. The series offers superior stability and lower noise compared to discrete Zener solutions. The T-series typically denotes specific package configurations suitable for modern surface-mount manufacturing processes.

Replacement Considerations

Direct substitutes may include other Renesas UPC1093 variants with different packages or accuracies. Verify pin compatibility and electrical specifications before replacing. Consult the manufacturer's obsolescence management page for qualified alternatives.
