Overview
The AS431HMANTR-G1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within an ambient temperature range of -40°C to +125°C and utilizes the SOT-23 package with a mirror pin-out configuration. The device provides programmable output voltages from 2.495V to 36V with a guaranteed initial voltage tolerance of 0.5%. It features a typical low equivalent full-range temperature coefficient of 20PPM/°C, a sink current capacity ranging from 0.5mA to 100mA, and low output noise characteristics.
Feature Summary
- Features sharp turn-on characteristics and high stability under capacitive loads
- Offers low temperature deviation and low output impedance for precise regulation
- Compliant with RoHS standards and available in lead-free green molding compounds
Applications
- Switching power supplies
- Chargers
- Voltage adapters
- Graphic cards
- Precision voltage references
Procurement Notes
Verify that the specific ordering suffix matches the required pin-out configuration, as this part number designates the mirror pin-out variant. Confirm the voltage tolerance grade corresponds to the 0.5% specification. Ensure the package type aligns with the SOT-23 footprint requirements for the target PCB layout. Cross-reference the environmental compliance documentation to confirm adherence to applicable regional directives.
Selection Notes
Select this component when a mirror pin-out configuration is necessary for board routing optimization. The 0.5% initial accuracy makes it suitable for applications requiring tighter voltage reference tolerances than standard 1.0% variants. Consider the thermal resistance characteristics of the SOT-23 package when designing for high-power dissipation scenarios within the specified operating temperature range.
Part Context
This component belongs to the AS431H series of adjustable precision shunt regulators. The series includes variants with normal or mirror pin-outs and different voltage tolerance grades. The AS431H series serves as a direct replacement for Zener diodes in various power management circuits, offering superior stability and lower temperature coefficients compared to traditional discrete solutions.

FAQ
What is the difference between the AS431HMANTR-G1 and AS431HANTR-G1?
The primary difference is the pin-out configuration. The AS431HMANTR-G1 uses a mirror pin-out, while the AS431HANTR-G1 uses a normal pin-out. Both share identical electrical specifications and package types.
Is the AS431HMANTR-G1 suitable for automotive applications?
Standard production does not automatically qualify for automotive use. For automotive applications requiring AEC-Q100 qualification and IATF 16949 manufacturing, customers must contact Diodes Incorporated directly.
