1N4619/TR

Single Zener Diodes Overview

The Microchip Technology 1N4619/TR is a Zener diode with a nominal voltage of 3 V and a maximum impedance of 1600 ohms. It operates within a temperature range of -65 °C to +175 °C, dissipating up to 500 mW of power. The device features a 5% voltage tolerance and a maximum reverse leakage current of 400 nA at the test current of 250 µA. Packaged in a DO-35 axial leaded format on a tape and reel, it serves as a reliable voltage regulator component.

Single Zener Diodes Procurement Notes

Verify that the specific suffix matches the required packaging configuration, as standard bulk versions exist alongside tape and reel variants. Confirm compliance requirements against the manufacturer's latest documentation, noting that certain military-grade qualifications may differ from commercial specifications. Ensure the ordering code aligns precisely with the intended application environment and regulatory standards.

Single Zener Diodes Selection Notes

Select this component when a precise 3 V regulation point is necessary within a compact axial package. Consider the high operating temperature limit for environments exceeding standard commercial ranges. Evaluate the impedance value against load requirements to ensure adequate regulation performance under varying current conditions without exceeding power dissipation limits.

Single Zener Diodes Part Context

This part belongs to the 1N4614 through 1N4627 series of 500 mW Zener diodes manufactured by Microchip Technology. These devices are characterized by their glass DO-35 encapsulation and internal metallurgical bonds. The series offers various voltage options and tolerance grades, catering to diverse precision regulation needs in both commercial and high-reliability sectors.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N4619 variants such as the 1N4619 or JANTX1N4619, provided the packaging and qualification levels match the system requirements. Cross-reference with equivalent industry-standard parts only if electrical parameters and physical dimensions are identical.
