Overview
The Nexperia 1N4748A,133 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 22 V with a ±5% tolerance. 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 forward voltage of 1.2 V at 200 mA, a test current of 11.5 mA, a differential resistance of 23 Ω, and a reverse current of 5 µA.
Feature Summary
- Hermetically sealed small glass package construction
- Low voltage regulation capability
- Wide operating temperature range
Applications
- Low voltage stabilizers
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as reel or cut tape configuration. Confirm RoHS compliance status and ensure the component meets required environmental standards for the intended application before finalizing procurement orders.
Selection Notes
Select this component when a stable 22 V reference is required in through-hole designs. Ensure the circuit design accommodates the specified differential resistance and test current conditions. Verify that the thermal management strategy supports the 1000 mW power dissipation limit under expected ambient conditions.
Part Context
This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series offers nominal working voltages ranging from 3.3 V to 24 V. All devices in this family share the same SOD66 axial leaded package and hermetically sealed glass construction.
Replacement Considerations
Direct substitutes include parts from other manufacturers using the standard 1N4748A designation. Verify pinout compatibility and electrical parameter alignment before substitution.
