PLVA2656A,215

Overview

The PLVA2656A,215 is a low-voltage avalanche regulator double diode from the PLVA2600A series. It features two high-performance voltage regulator diodes with common anodes housed in a small SOT23 (TO-236AB) plastic surface-mount package. The nominal working voltage is 5.6 V at a test current of 250 μA, with a tolerance of ±4%. Key electrical characteristics include a maximum dynamic resistance of 100 Ω and a reverse leakage current of 1 μA. The device supports a total power dissipation of 250 mW per diode and operates within a junction temperature range of -65 °C to +150 °C.

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 tolerances of VZ with a working voltage range nominally between 5.0 V and 6.8 V

Applications

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

Procurement Notes

Verify component authenticity through official Nexperia channels or authorized distributors. Confirm the specific ordering suffix matches the required packaging format. Check the latest product status documentation as availability may change. Ensure compliance with RoHS directives and automotive qualification standards if applicable to the design requirements.

Selection Notes

Select this component for designs requiring dual voltage regulation in a compact footprint. Consider the 5.6 V nominal voltage and 250 μA test current when designing bias networks. Evaluate thermal constraints based on the 250 mW power dissipation rating. Verify that the low noise and hard breakdown knee characteristics meet the specific signal integrity requirements of the application.

Part Context

This part belongs to the PLVA2600A series, which includes variants ranging from PLVA2650A to PLVA2668A. All members share the same SOT23 package and common anode configuration but differ in nominal Zener voltage. The series is designed for low-power applications where space and noise performance are critical factors.

Replacement Considerations

Direct replacements must match the PLVA2600A series specifications. Verify pinout compatibility and ensure the substitute offers similar dynamic impedance and noise levels. Cross-reference with Nexperia's official substitution guides for validated alternatives.
