PLVA2662A,215

Overview

The PLVA2662A,215 is a low-voltage avalanche regulator double diode from the PLVA2600A series manufactured by Nexperia. It features two high-performance voltage regulator diodes with common anodes housed in a small SOT-23 plastic surface-mount package. The nominal Zener voltage is 6.2 V at a test current of 250 μA, with a maximum tolerance of ±0.2 V (ranging from 6.0 V to 6.4 V). Key electrical characteristics include a dynamic resistance of 100 Ω and a reverse leakage current of 100 nA at 80% of nominal voltage. The device supports a continuous forward current of 250 mA and a total power dissipation of 250 mW per diode.

Feature Summary

• Very low dynamic impedance at low currents, approximately one-twentieth of conventional series
• Hard breakdown knee for stable regulation performance
• Low noise characteristics, approximately one-tenth of conventional series
• Small working voltage tolerances within the 5.0 to 6.8 V range

Applications

• Low current, low power, low noise applications
• CMOS RAM back-up circuits
• Voltage stabilizers
• Voltage limiters
• Smoke detector relays

Selection Notes

Select this component when designing circuits requiring dual voltage references or clamping functions in a compact footprint. The common anode configuration allows for efficient space utilization in dense layouts. Ensure the operating current remains near the 250 μA test point for optimal voltage accuracy and noise performance. Consider the thermal resistance values if multiple devices are mounted closely on the PCB.

Part Context

This part belongs to the PLVA2600A series, which includes variants ranging from PLVA2650A to PLVA2668A. All members share the same SOT-23 package and general structural features but differ in nominal Zener voltage. The PLVA2662A specifically targets the 6.2 V segment of this low-voltage avalanche regulator family.

Replacement Considerations

Direct substitutes within the same series include PLVA2659A and PLVA2665A, provided their respective nominal voltages (5.9 V and 6.5 V) align with circuit requirements. Cross-series replacements require careful evaluation of dynamic impedance and noise specifications.
