Product details
Overview
PLVA2653A,215 from Nexperia is a low-voltage avalanche regulator double diode with common anode configuration in SOT23 package, designed for precision voltage stabilization at 5.3 V nominal working voltage (IZ = 250 μA), 250 Ω dynamic impedance, and 1.6 mV/K temperature coefficient. It serves in CMOS RAM backup circuits where low noise (1.0 μV/√Hz), hard breakdown knee, and stable low-current regulation are critical.
For engineers reviewing the PLVA2653A,215 datasheet, PLVA2653A,215 pinout, PLVA2653A,215 application, or PLVA2653A,215 equivalent, key selection factors include its dual-cathode/common-anode topology, 5.3 V ±0.2 V tolerance at 250 μA, sub-μA reverse leakage at 80% VZ, and thermal resistance of 500 K/W on FR4 PCB.
Technical Context
The PLVA2653A,215 implements two monolithically integrated Zener-type avalanche diodes sharing a single anode terminal, enabling compact dual-rail voltage reference or clamping in space-constrained designs. Its low 250 Ω dynamic impedance at 250 μA ensures minimal output voltage variation under load transients.
It operates with a 1.6 mV/K temperature coefficient and delivers 1.0 μV/√Hz noise density at 1 kHz - significantly lower than conventional regulators - making it suitable for low-noise analog monitoring paths and memory retention circuits requiring long-term voltage stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 5.30 V at IZ = 250 μA - precise reference point for low-power biasing |
| RZ (dynamic impedance) | 250 Ω - maintains tight regulation under small-signal current variations |
| TC (temp. coeff.) | 1.6 mV/K - predictable drift behavior across industrial temperature range |
| IR (reverse leakage) | 5000 nA at 80% VZ - enables ultra-low standby power in battery-backed systems |
| Vn (noise density) | 1.0 μV/√Hz - supports high-SNR sensing and reference applications |
| Ptot (single diode) | 250 mW - defines maximum continuous dissipation per diode on FR4 PCB |
| Package | SOT23 (TO-236AB) - surface-mount footprint compatible with automated assembly |
Pinout & Package
SOT23 plastic surface-mounted package (TO-236AB), 3-lead, dimensions per JEDEC MO-203AA: 2.9 mm × 1.3 mm × 1.0 mm height, 0.95 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K1) | First regulated output node; connects to load requiring 5.3 V reference |
| 2 | Cathode (K2) | Second independent regulated output node; enables dual-rail stabilization |
| 3 | Common Anode (A) | Shared return path; simplifies PCB routing and reduces component count vs. discrete diodes |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Sharp, well-defined Zener transition improves regulation accuracy at low currents |
| Low noise performance | 1.0 μV/√Hz noise density enables use in precision analog signal chains |
| Very low dynamic impedance | 250 Ω at 250 μA - 20× lower than standard Zeners, reducing output ripple |
| Small VZ tolerances | ±0.2 V at 250 μA - eliminates need for post-production trimming in many applications |
| Common-anode dual-diode topology | Single-package solution for dual-reference or differential clamping without layout mismatch |
Applications
| CMOS RAM Backup Circuit | Smoke Detector Relay Interface |
|---|---|
Use Scenario: Maintaining SRAM data during main power loss using coin-cell battery. IC Role / Device Role / Timing Role: Dual-cathode Zener provides stable 5.3 V bias to RAM VCC and reset supervisor input. Use Value: Sub-μA leakage at 80% VZ extends battery life beyond 10 years; low noise prevents false resets. | Use Scenario: Clamping relay coil flyback voltage while powering low-power logic in battery-operated detectors. IC Role / Device Role / Timing Role: One diode limits coil voltage spike; second stabilizes microcontroller supply rail. Use Value: Hard breakdown knee ensures reliable clamping at 5.3 V; 30 W non-repetitive peak power handles transient energy. |
| Voltage Limiter for Sensor Signal Chain | Low-Power Voltage Stabilizer in Wearables |
Use Scenario: Protecting ADC input from overvoltage in environmental sensor modules. IC Role / Device Role / Timing Role: Acts as bidirectional clamp (reverse-biased Zener + forward diode) at signal node. Use Value: 250 Ω dynamic impedance minimizes signal distortion during clamping events; low noise avoids corrupting weak sensor signals. | Use Scenario: Providing stable 5.3 V reference to real-time clock and BLE radio in hearable devices. IC Role / Device Role / Timing Role: Regulator diode supplies clean bias to timing circuitry and RF front-end. Use Value: 1.6 mV/K tempco ensures <±10 mV drift over –40°C to +85°C; 250 mW rating supports intermittent transmit bursts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage dual-Zener regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1,215 | Single 5.1 V Zener in SOT23; no dual-cathode topology; RZ = 600 Ω; higher noise | Requires two devices for dual-rail; less suitable for low-noise RAM backup | Lower cost where dual functionality is unnecessary and noise is not critical |
| PLVA2656A,215 | 5.6 V nominal VZ; 100 Ω RZ; 1.9 mV/K tempco; lower IR (1000 nA at 80% VZ) | Better for higher-voltage rails; tighter regulation but less optimal for 5.3 V–specific designs | Select when system requires 5.6 V reference or improved dynamic impedance at same current |
Compared with BZX84-C5V1,215 and PLVA2656A,215, the PLVA2653A,215 uniquely balances 5.3 V nominal voltage, 250 Ω regulation, and 5000 nA leakage - making it optimal for legacy CMOS RAM backup where exact VZ alignment and dual-cathode integration reduce board area and BOM count.

FAQ
What is the maximum continuous power dissipation per diode for PLVA2653A,215?
The PLVA2653A,215 has a total power dissipation limit of 250 mW when only one diode is loaded, measured at Tamb = 25 °C on FR4 PCB. This value drops to 180 mW when both diodes operate simultaneously due to shared thermal path in the SOT23 package.
Can PLVA2653A,215 be used as a standalone voltage reference in precision analog circuits?
Yes - its 1.0 μV/√Hz noise density, 250 Ω dynamic impedance, and 1.6 mV/K temperature coefficient make it suitable for medium-precision references in non-critical analog paths. However, it lacks initial accuracy better than ±0.2 V, so calibration may be needed for high-accuracy applications.
How does the common-anode configuration affect PCB layout compared to two discrete Zeners?
The common-anode structure reduces trace inductance between diodes and eliminates layout-induced voltage mismatch. It allows symmetrical placement relative to ground plane and cuts component count by half - critical for miniaturized wearables and sensor nodes where space and assembly cost matter.
Is PLVA2653A,215 qualified for automotive applications?
No - the PLVA2653A,215 is not AEC-Q101 qualified. Its datasheet specifies operation up to 150 °C junction temperature but lacks automotive-grade reliability testing, qualification reports, or guaranteed PPAP documentation required for automotive use.
