CDLL5922B

Single Zener Diodes Overview

The CDLL5922B is a 1.5 W Zener diode in the JEDEC DO-213AB MELF package, featuring a 7.5 V nominal voltage with 5% tolerance. It operates within a -65°C to +175°C temperature range and exhibits a maximum reverse leakage current of 6.0 µA at 6.0 V. The device has a dynamic impedance of 3.0 Ohms at a test current of 50.0 mA and a knee impedance of 0.5 Ohms at 400 mA. Forward voltage is specified at 1.2 V max for 200 mA forward current.

Single Zener Diodes Feature Summary

• Hermetically sealed glass package with metallurgically enhanced internal contacts for high reliability.
• Surface mount equivalent of axial-leaded 1N5922B for high-density mounting.
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020.
• Inherently radiation hard design suitable for demanding environments.

Single Zener Diodes Applications

• Voltage regulation over broad ranges of operation current and temperature.
• High density surface mounting applications requiring low parasitic characteristics.
• High reliability applications requiring screening in accordance with MIL-PRF-19500.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's nomenclature to confirm RoHS compliance status and reliability level. Confirm that the required voltage tolerance matches the 'B' designation for 5%. Ensure the procurement specification aligns with the available tape and reel options if automated assembly is intended.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability circuits. The DO-213AB package offers lower thermal resistance compared to standard plastic packages. Verify that the 1.5 W power dissipation rating meets the thermal requirements of the target application environment.

Single Zener Diodes Part Context

This part belongs to the 1N5913B through 1N5956B series of 1.5 Watt Zener diodes. The CDLL prefix denotes the metallurgically bonded glass surface mount variant. These devices serve as direct surface mount replacements for traditional axial-leaded components while maintaining similar electrical performance profiles.

Single Zener Diodes Replacement Considerations

Direct equivalents include the 1N5922BUR-1. Alternative package formats such as DO-41 (axial), SMBG (tabbed SMD), SMAJ (tabbed SMD), and Powermite are available within the same series for different mechanical integration needs.
