MMTL431AR-AQ

Overview

The MMTL431AR-AQ is an adjustable precision diode shunt regulator manufactured by Diotec Semiconductor. It features a reference voltage of 2.495 V with a narrow tolerance band of ±0.5%. The device operates within a cathode voltage range of VREF to 36 V and supports a DC cathode current from 1 mA to 100 mA. It is housed in a SOT-23 (TO-236) surface-mount package. The component is AEC-Q100 qualified, ensuring compliance with automotive standards.

Feature Summary

Temperature compensated for stable performance across operating ranges
Reverse pinning configuration available in the R version
Low output impedance for precise regulation
Narrow voltage tolerance band

Applications

Precision voltage reference for voltage regulators and comparators
Replacement for low voltage Zener diodes
Low device-count power supply for microcontrollers
Converter secondary side control

Procurement Notes

Verify that the specific part number suffix matches the required qualification level. Confirm the package type corresponds to the design footprint. Ensure the application environment aligns with the specified commercial or industrial grade ratings. Check for any RoHS compliance documentation requirements relevant to the target market regulations.

Selection Notes

Select this component when a temperature-compensated shunt regulator with tight voltage tolerance is required. The reverse pinning option in the AR variant aids in PCB layout flexibility. Consider the minimum regulation current specifications when designing bias networks. Evaluate the dynamic output impedance characteristics for high-frequency stability requirements.
