The Nexperia PZU8.2DB2,115 is a dual isolated general-purpose Zener diode housed in an SOT353 (SC-88A) surface-mount package. It features two independent diodes within a single five-lead component. The nominal Zener voltage is 8.2 V with a tolerance of approximately ±2%. Total power dissipation is limited to 250 mW at ambient temperatures up to 25 °C. Key electrical parameters include a maximum reverse current of 10 μA and a differential resistance of 60 Ω at IZ = 5 mA. The device operates within a junction temperature range of -55 °C to +150 °C and is qualified under the AEC-Q101 automotive standard.
Verify the specific ordering suffix against official Nexperia documentation to confirm package variant and halogen-free status. Confirm that the requested quantity aligns with standard packing methods such as tape and reel options. Ensure compatibility with RoHS directives and check for any recent product change notices affecting availability or specifications before finalizing procurement orders.
Select this component when dual isolated Zener regulation is required in a minimal footprint. The SOT353 package supports high-density PCB layouts. Consider the total power dissipation limit of 250 mW and ensure adequate thermal management on the FR4 PCB. Verify that the ±2% tolerance meets the precision requirements of the target application circuit design.
This part belongs to the PZUxDB2 series, which offers a wide working voltage range from 2.7 V to 24 V. The series provides various tolerance options including B2 for tight ±2% accuracy. It is designed for general-purpose regulation in compact electronic devices requiring reliable voltage stabilization in small surface-mount form factors.
Direct substitutes within the same series include other PZUxDB2 variants with different voltage ratings. Cross-series replacements may require verification of pinout compatibility and power dissipation limits. Ensure any alternative maintains the dual isolated configuration and AEC-Q101 qualification if automotive use is intended.
The marking code for the PZU8.2DB2 is TD.
Pin 1 is the anode for diode 1, Pin 3 is the anode for diode 2, Pin 4 is the cathode for diode 2, Pin 5 is the cathode for diode 1, and Pin 2 is not connected.
The non-repetitive peak reverse power dissipation (PZSM) is 40 W.
