MMTL431BR

Overview

The MMTL431BR is an adjustable precision diode shunt regulator manufactured by Diotec Semiconductor, housed in a SOT-23 package. It features a reference voltage (VREF) of 2.495 V with a tolerance of ±0.5%. The device supports a cathode current range from 1 mA to 100 mA and operates within a cathode voltage span of VREF to 36 V. Key electrical characteristics include a dynamic output impedance of approximately 0.15 Ω and a maximum junction temperature of 150°C.

Feature Summary

Temperature compensated for stable operation across varying thermal conditions
Low output impedance ensuring precise regulation performance
Narrow tolerance band for high accuracy applications
Version B variant optimized with low minimum regulation current

Applications

Precision voltage reference for voltage regulators and comparators
Replacement for low voltage Zener diodes
Low device-count power supply design for microcontrollers
Secondary side control for flyback converters

Procurement Notes

Verify the specific ordering suffix to confirm compliance status. Standard versions are commercial/industrial grade. Versions with -Q or -AQ suffixes meet AEC-Q100 automotive standards. Confirm RoHS compliance and REACH registration requirements prior to integration into final assemblies.

Selection Notes

Select the MMTL431BR when a low minimum regulation current is required compared to standard variants. Ensure the application maintains a cathode current between 1 mA and 100 mA for optimal stability. Verify that the load capacitance exceeds 5 µF to prevent oscillation during operation.

Part Context

This component belongs to the MMTL431 family of adjustable precision shunt regulators. It serves as a direct functional alternative to traditional Zener diodes where tighter tolerance and lower temperature drift are necessary. The BR designation specifically indicates the version engineered for minimal start-up current requirements.
