ZTL431BCSTZ

Overview

The ZTL431BCSTZ is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides excellent temperature stability and an output current handling capability up to 100mA. The output voltage is programmable between 2.5V and 20V using two external divider resistors. This device serves as a high-performance replacement for zener diodes in applications requiring improved regulation characteristics.

Feature Summary

Offers B grade initial tolerance of 0.5% at +25°C
Operates within an ambient temperature range of -40°C to +125°C
Features low dynamic output impedance with typical value of 0.2Ω
Totally lead-free, fully RoHS compliant, and halogen/antimony free

Applications

Opto-coupler linearization
Linear regulators
Improved zener diode replacement
Variable reference circuits

Procurement Notes

Verify the specific package type and suffix against official Diodes Incorporated documentation before procurement. Confirm that the B grade designation matches the required 0.5% initial tolerance specification. Ensure the ordering code aligns with the desired reel size and tape width requirements for your manufacturing process.

Selection Notes

Select this component when precise voltage referencing is required across wide temperature variations. The B grade offers tighter initial tolerance compared to standard A grade variants. Consider the maximum cathode voltage rating and sink current limits to ensure reliable operation within the recommended operating conditions for the target application.

Part Context

This part belongs to the ZTL431/ZTL432 family of cost-effective adjustable precision shunt regulators. These devices are functionally equivalent to TL431/TL432 types but feature distinct pinouts in certain packages like SOT23F. They provide enhanced performance over traditional zener diodes while maintaining compatibility with common design architectures.

Replacement Considerations

Functionally equivalent to TL431/TL432 except for maximum operation voltage. Verify pinout compatibility if replacing components in existing SOT23 or SOT23F footprints. Check thermal dissipation requirements against absolute maximum ratings during substitution.
