NXP Semiconductors PLVA2662A,215

Overview

PLVA2662A,215 from Nexperia is a low-voltage avalanche regulator double diode with common anode configuration in SOT23 package, designed for precision voltage stabilization at 6.2 V nominal working voltage (IZ = 250 μA), dynamic resistance ≤100 Ω, temperature coefficient 2.65 mV/K, and total power dissipation up to 180 mW (dual diode loaded). It serves in CMOS RAM backup circuits where low noise (<1.0 μV/√Hz) and hard breakdown knee are critical.

For engineers reviewing the PLVA2662A,215 datasheet, PLVA2662A,215 pinout, PLVA2662A,215 application, or PLVA2662A,215 equivalent, key selection factors include its dual-cathode/common-anode topology, 100 nA reverse current at 80% VZ, 0.05 μA IR at 90% VZ, and suitability for low-current (<250 μA), low-power (<250 mW), low-noise voltage limiting in space-constrained SMD designs.

Technical Context

This device implements two monolithic Zener-type avalanche regulator diodes sharing a single anode terminal, enabling compact dual-rail voltage reference or clamping in a single SOT23 footprint. Its hard breakdown knee and low dynamic impedance (≤100 Ω at IZ = 250 μA) ensure stable regulation under light-load conditions typical of memory backup and sensor biasing.

Designed for operation at junction temperatures up to 150 °C, it delivers tight VZ tolerance (6.00–6.40 V at IZ = 250 μA) and low temperature drift (2.65 mV/K), with reverse current as low as 0.9 nA at 50% VZ - critical for battery-backed systems requiring ultra-low standby leakage.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous forward current rating for PLVA2662A,215?

The maximum continuous forward current (IF) is 250 mA per diode, as specified in the Absolute Maximum Ratings table. This rating assumes device mounting on an FR4 PCB and applies to each cathode-to-anode path independently. Exceeding this value risks permanent junction damage due to thermal runaway.

Can PLVA2662A,215 be used in place of a single Zener diode like BZX84-C6V2?

Yes, but only one cathode (Pin 1 or Pin 2) should be used with the common anode (Pin 3), effectively operating it as a single 6.2 V Zener. The unused cathode must be left unconnected or tied to the same potential as the active cathode - floating it is acceptable, but shorting cathodes degrades regulation performance.

What does the "215" suffix in PLVA2662A,215 indicate?

The "215" is a Nexperia internal ordering code denoting tape-and-reel packaging (10,000 units per reel), RoHS-compliant finish, and standard reliability screening. It does not affect electrical specifications or package dimensions - all PLVA2662A variants share identical silicon and SOT23 mechanical form factor.

Is PLVA2662A,215 suitable for automotive applications?

No - PLVA2662A,215 is not qualified to AEC-Q101 or automotive-grade reliability standards. Its datasheet specifies operation up to 150 °C junction temperature but lacks automotive-specific qualification testing (e.g., HTOL, temperature cycling, ESD robustness beyond 8 kV HBM). Use only in industrial, consumer, or commercial environments unless explicitly validated by end-equipment OEM.
