Overview
The Nexperia 1N4731A,113 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It features a nominal working voltage of 4.3 V with a tolerance of ±5%. The device supports a maximum total power dissipation of 1000 mW and operates within a junction temperature range of -65 °C to +200 °C. Key electrical characteristics include a test current of 58 mA, a differential resistance of 9 Ω, and a maximum reverse current of 10 µA at the test current condition.
Feature Summary
- Hermetically sealed small glass package construction
- Low voltage regulation capability
- Axial leaded configuration for through-hole mounting
Applications
- Low voltage stabilizers
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as tape and reel quantities or cut tape availability. Confirm RoHS compliance status and REACH registration requirements prior to procurement. Ensure the selected variant matches the required hermetic sealing specifications for the intended environmental conditions.
Selection Notes
Select this component when a stable reference voltage near 4.3 V is required in circuits utilizing axial leaded packages. Consider the thermal resistance from junction to tie-point and the maximum power dissipation limits when designing heat management strategies. Verify that the operating current remains within the specified working current range to maintain accurate voltage regulation performance.
Part Context
This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series provides nominal working voltages ranging from 3.3 V to 24 V. All devices in this family share the same SOD66 (DO-41) hermetically sealed glass package format and general structural characteristics.
Replacement Considerations
Direct substitutes include other manufacturers' equivalents meeting the 1N4731A specification, such as those from Micro Commercial Components (e.g., 1N4731A-TP). Verify pinout compatibility and electrical parameter alignment before substitution.
