PLVA2665A,215

Overview

The PLVA2665A,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 a common anode configuration housed in a small SOT-23 (TO-236AB) surface-mount plastic package. The nominal Zener voltage is 6.2 V with a tolerance of +/- 2%. Operating at a test current of 250 µA, it offers very low dynamic impedance and hard breakdown knee characteristics. Total power dissipation is rated at 250 mW, with a non-repetitive peak reverse power dissipation of 30 W. The device supports a maximum junction temperature of 150 °C and is AEC-Q101 qualified for automotive reliability.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific part number PLVA2665A,215 against official Nexperia documentation to confirm availability status and exact electrical parameters. Ensure compatibility with SOT-23 footprint requirements and check for any specific handling precautions related to ESD sensitivity during assembly.

Selection Notes

Select this component for designs requiring precise low-voltage regulation in compact spaces. The dual common anode structure allows for efficient use of board area. Consider the 250 µA test current requirement when designing bias networks to ensure accurate voltage referencing under operating conditions.

Part Context

This device belongs to the PLVA2600A series, which includes variants ranging from PLVA2650A to PLVA2668A. All members share similar physical packaging and general performance traits but differ in nominal Zener voltage. The series is designed to replace conventional zener diodes where size and noise are critical constraints.

Replacement Considerations

Direct substitutes within the same series include PLVA2650A through PLVA2668A, provided the specific Zener voltage matches the circuit design requirements. Verify that alternative components maintain the same SOT-23 package and common anode configuration to ensure pinout compatibility.
