NJM17431F24A-TE1

Overview

The NJM17431F24A-TE1 is an adjustable precision shunt regulator manufactured by Nisshinbo Micro Devices. It operates within a voltage range from VREF to 36V and features a reference voltage of 2.495V with ±0.8% accuracy. The device utilizes bipolar technology and is housed in a SOT-23-5 package. Recommended operating conditions specify a cathode voltage between VREF and 36V, and a cathode current ranging from 0.5mA to 100mA. The maximum power dissipation is 650mW on a four-layer board.

Feature Summary

• Adjustable output voltage settable between the reference voltage and 36V using two external resistors
• High precision reference voltage with ±0.8% accuracy tolerance
• Wide safety operating boundary area allowing stable operation with large output capacitance

Applications

• Industrial equipment
• Home electrical appliances
• Replacement for Zener diodes

Procurement Notes

Verify the specific ordering suffix TE1 corresponds to the tape and reel packaging format containing 3,000 pieces per reel. Confirm that the F24A designation matches the required 2.495V reference voltage variant rather than the 2.5V version. Ensure compatibility with the SOT-23-5 surface mount footprint during procurement planning.

Selection Notes

Select this component when a precise adjustable shunt regulator is needed for general electronic applications. The bipolar technology provides robust performance across a wide temperature range. Consider the thermal resistance characteristics if high power dissipation is expected in the design environment.
