Product details
Overview
PLVA650A from Nexperia is a low-voltage avalanche regulator diode in SOT23 (TO-236AB) package, designed for precision voltage stabilization at 5.00 V nominal working voltage with ±0.20 V tolerance, 700 Ω dynamic resistance, and 0.4 V line regulation across 100 µA to 1 mA current range. It serves as a low-noise, low-power reference in CMOS RAM backup circuits and voltage limiters.
For engineers reviewing the PLVA650A datasheet, PLVA650A pinout, PLVA650A application, or PLVA650A equivalent, key selection criteria include its 5.00 V nominal Zener voltage at 250 µA, ultra-low reverse current (34 nA at 50 % VZ), hard breakdown knee, 250 mW total power dissipation, and SOT23 surface-mount compatibility.
Technical Context
This device operates as an avalanche-mode voltage reference diode-not a forward-biased regulator-delivering stable reverse-bias regulation with minimal temperature drift (0.20 mV/K) and low noise density (≤1.0 µV/√Hz at 1 kHz). Its hard breakdown knee ensures predictable turn-on without soft rollover.
Designed for low-current operation (IZ = 100 µA to 1 mA), it achieves tight voltage control via low dynamic impedance and exhibits negligible hysteresis under repetitive load transients. Thermal resistance to ambient is 500 K/W on FR4 PCB, limiting practical continuous dissipation to ≤250 mW at Tamb = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VZ | 5.00 V at IZ = 250 µA - defines primary regulation point for low-power bias networks |
| VZ Tolerance | ±0.20 V (4.80–5.20 V) - enables precise voltage clamping in signal conditioning paths |
| Dynamic Resistance | 700 Ω - determines output impedance and load regulation sensitivity below 1 mA |
| Reverse Current | 34 nA at VR = 2.5 V - ensures minimal leakage in battery-backed memory retention |
| Line Regulation | 0.4 V from ILO = 100 µA to IHI = 1 mA - quantifies voltage shift under operating current variation |
| Temperature Coefficient | +0.20 mV/K - indicates near-zero drift over industrial temperature range |
| Total Power Dissipation | 250 mW at Tamb = 25 °C - sets maximum steady-state thermal budget on standard FR4 PCB |
Pinout & Package
Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with standard footprint per Fig. 1 and reflow soldering land pattern per Fig. 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential node; reverse-bias current enters here during regulation |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating-no PCB trace or pad required |
| 3 | Cathode (K) | Connected to higher-potential node; regulated voltage appears at this terminal relative to A |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Sharp, non-hysteretic reverse conduction onset improves accuracy in low-current threshold detection |
| Low noise voltage density | ≤1.0 µV/√Hz at 1 kHz - reduces interference in analog sensor reference paths |
| Very low dynamic impedance | 700 Ω at 250 µA - maintains regulation stability under varying load currents |
| Small VZ tolerances | ±0.20 V - eliminates need for post-assembly trimming in cost-sensitive consumer designs |
| Non-repetitive peak power rating | 30 W at tp = 100 µs - supports transient overvoltage suppression in ESD-coupled interfaces |
Applications
| CMOS RAM Backup Circuit | Voltage Limiter for Sensor Interface |
|---|---|
Use Scenario: Maintaining SRAM data integrity during main power loss using coin-cell or supercapacitor backup. IC Role / Device Role / Timing Role: Low-leakage voltage clamp ensuring VCC stays ≥ 2.5 V while minimizing standby current draw. Use Value: 34 nA reverse current at 2.5 V enables >10-year backup life with typical 22 µF supercapacitors. |
Use Scenario: Protecting ADC input pins from overvoltage spikes induced by nearby relay switching or EMI. IC Role / Device Role / Timing Role: Fast-acting shunt limiter clamping transient excursions above 5.2 V before damage occurs. Use Value: Hard breakdown knee and 30 W non-repetitive peak power rating absorb 100 µs surges without degradation. |
| Voltage Stabilizer for Clock Oscillator | Low-Noise Reference for Precision Comparator |
Use Scenario: Providing stable bias to crystal oscillator ICs requiring tightly regulated 5.0 V supply rails. IC Role / Device Role / Timing Role: Low-noise shunt regulator replacing linear LDO where quiescent current must be <100 µA. Use Value: 1.0 µV/√Hz noise density prevents phase jitter increase in 1–10 MHz clock sources. |
Use Scenario: Setting accurate trip thresholds in battery-monitoring comparators for Li-ion cell voltage detection. IC Role / Device Role / Timing Role: Precision Zener reference with ±0.20 V tolerance defining 4.20 V full-charge detection point. Use Value: 0.20 mV/K temperature coefficient limits threshold drift to <10 mV over –40 °C to +85 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1 | 5.1 V nominal VZ, ±5 % tolerance (±0.255 V), 1000 Ω RZ, 100 nA IR at 2.55 V | Higher tolerance and leakage reduce accuracy in long-term backup or low-noise references | Select when cost priority outweighs precision; not suitable for sub-100 nA leakage requirements |
| MMSZ5222BS | 5.1 V nominal VZ, ±5 % tolerance, 1700 Ω RZ, 100 nA IR at 2.55 V, SOD-323 package | Larger package footprint and higher dynamic impedance degrade regulation in space-constrained, low-current nodes | Prefer only if SOD-323 layout compatibility is mandatory; avoid where 700 Ω RZ or 34 nA IR are design-critical |
Compared with BZX84-C5V1 and MMSZ5222BS, PLVA650A delivers tighter VZ tolerance (±0.20 V vs. ±0.255 V), lower dynamic resistance (700 Ω vs. ≥1000 Ω), and significantly reduced leakage (34 nA vs. ≥100 nA), making it uniquely suited for high-accuracy, ultra-low-power voltage reference roles.

FAQ
What is the guaranteed Zener voltage range for PLVA650A at 250 µA test current?
The PLVA650A guarantees a working voltage of 4.80 V to 5.20 V when measured at IZ = 250 µA and Tj = 25 °C, as specified in Table 7 of the official datasheet Rev. 4. This ±0.20 V tolerance is tighter than standard 5 % Zeners and is validated across production lots.
Can PLVA650A be used in place of a standard 5.1 V Zener like BZX84-C5V1?
PLVA650A is not a direct replacement due to its 5.00 V nominal voltage, tighter tolerance (±0.20 V vs. ±5 %), and significantly lower leakage (34 nA vs. ~100 nA). Substitution requires circuit-level validation of voltage margin, noise sensitivity, and standby current impact.
Why does Pin 2 show 'n.c.' and how should it be handled on the PCB?
Pin 2 is internally not connected and must remain electrically floating-no trace, pad, or solder mask opening is required. Including a pad risks unintended parasitic coupling or solder bridging; Nexperia's recommended footprint (Fig. 2) omits copper at Pin 2 location.
Is PLVA650A qualified for automotive applications?
No. Per Revision History Section 13, PLVA650A is explicitly marked as non-automotive qualified. Nexperia offers separate –Q qualified variants (e.g., PLVA650AQ) for AEC-Q101-compliant designs; this part is intended for industrial and consumer use only.
