Detailed Description for TL431ASA-7
Product Overview
TL431ASA-7 from Diodes Incorporated is a surface-mount shunt voltage reference IC with an adjustable output. The device provides a 2.495 V minimum/fixed output and a 36 V maximum output, with ±1% tolerance and 100 mA output current. It is supplied in a SOT-23-3 package, also identified as TO-236-3 or SC-59, and operates over a -40°C to 125°C (TA) temperature range. The 700 µA cathode current specification supports current-related design checks in power-management and reference circuits.
Key Features
- Shunt voltage reference topology with adjustable output.
- 2.495 V minimum/fixed output and 36 V maximum output.
- ±1% tolerance.

Design & Procurement Notes
For design and procurement, use the exact part number TL431ASA-7 and confirm the surface-mount SOT-23-3 footprint, including TO-236-3 and SC-59 equivalents. The ±1% tolerance and 2.495 V minimum/fixed output are relevant to reference voltage accuracy planning, while the 36 V maximum output and 100 mA output current define circuit operating limits. The 700 µA cathode current should be considered alongside the selected supply and load conditions. The -40°C to 125°C (TA) range supports temperature-aware layout and component placement decisions. Designers should verify that the chosen circuit maintains the 700 µA cathode current within the -40°C to 125°C (TA) operating range.
