TJR431ASF

Overview

The TJR431ASF is a three-terminal programmable precision shunt regulator manufactured by Tae Jin Technology. It provides an adjustable output voltage up to 28V using two external resistors, with a nominal reference voltage of 2.495V. The device features a guaranteed 1% reference voltage tolerance and operates within a cathode current range of 100mA. It is characterized for operation from -40°C to +125°C and is supplied in an SOT-23-3L package.

Feature Summary

Programmable output voltage capability up to 28V via external resistor divider
Temperature compensated design ensuring thermal stability across the full operating range
Fast turn-on response and low output noise voltage characteristics

Applications

Shunt Regulator
Precision High-Current Series Regulator
Crowbar Circuit
PWM Converter With Reference
Voltage Monitor

Procurement Notes

Verify that the specific part number TJR431ASF corresponds to the 1% tolerance variant as indicated by the 'A' suffix in the ordering information. Confirm the package type is SOT-23-3L and check if the device is supplied on a reel. Ensure the manufacturer is identified as HTC or Tae Jin Technology based on the datasheet source.

Selection Notes

Select this component when a precise, temperature-compensated shunt regulator is required for circuits operating up to 28V. The 1% tolerance makes it suitable for applications demanding higher accuracy than standard Zener diodes. Consider the SOT-23-3L package size for space-constrained designs requiring fast turn-on and low noise performance.

Part Context

The TJR431 series serves as a high-performance replacement for traditional Zener diodes in various power management and signal conditioning applications. Manufactured by HTC (Tae Jin Technology), the device integrates active output circuitry to provide sharp turn-on characteristics. The family includes variants with different tolerances and packaging options to suit diverse electronic design requirements.
