PLVA2650A,215

Overview

The PLVA2650A,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 plastic surface-mount package. The device provides a nominal working voltage of 5.0 V at a test current (IZ) of 250 μA, with a maximum tolerance of ±0.20 V. It exhibits very low dynamic impedance and noise characteristics compared to conventional series. Key electrical parameters include a maximum total power dissipation of 250 mW per single diode loaded, a non-repetitive peak reverse power dissipation of 30 W, and a maximum junction temperature of 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 output, approximately one-tenth of conventional series
• Small tolerances of Zener voltage (VZ)

Applications

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

Procurement Notes

Verify the component status through official Nexperia or NXP channels before procurement. Confirm that the ordering suffix ',215' corresponds to the specific tape-and-reel packaging configuration required for your assembly line. Ensure the marking code '9J' matches the physical device received. Cross-reference the datasheet revision date against your design specifications to ensure compliance with the latest product data sheet standards.

Selection Notes

Select this component when designing circuits requiring precise low-voltage regulation with minimal noise interference. The dual common-anode configuration allows for efficient space utilization in compact designs. Consider the thermal resistance values (Rth j-a of 500 K/W) when determining heat dissipation requirements on the FR4 printed circuit-board. Ensure the operating current remains within the specified limits to maintain the low dynamic impedance benefits.

Part Context

The PLVA2650A belongs to the PLVA2600A series, which includes variants ranging from PLVA2650A to PLVA2668A. These devices share the same SOT23 package and internal architecture but differ in their nominal Zener voltages. The series was originally developed by NXP Semiconductors and is now managed under the Nexperia brand following the separation of the standard product business in 2017.

Replacement Considerations

Direct replacements within the same family include PLVA2653A, PLVA2656A, PLVA2659A, PLVA2662A, PLVA2665A, and PLVA2668A, provided the voltage requirement differs. Verify pin compatibility and thermal characteristics when substituting with other manufacturers' low-voltage avalanche diodes.
