Product details

Overview

PLVA659AVL from Nexperia is a low-voltage avalanche regulator diode in SOT23 (TO-236AB) package, designed for precision voltage stabilization at 5.90 V nominal working voltage with ±0.20 V tolerance, 100 Ω dynamic resistance at 250 µA, and 0.9 nA reverse current at 50 % V_Z. It serves as a low-noise, low-power reference in CMOS RAM backup and voltage limiter circuits.

For engineers reviewing the PLVA659AVL datasheet, PLVA659AVL pinout, PLVA659AVL application, or PLVA659AVL equivalent, key selection criteria include its hard breakdown knee, 2.40 mV/K temperature coefficient, 250 mW total power dissipation, and SOT23-compatible thermal resistance of 500 K/W in free air.

Technical Context

This device operates as a two-terminal Zener-type voltage reference using controlled avalanche breakdown in silicon, optimized for stable regulation below 6.8 V. Its low noise density (≤1.0 µV/√Hz at 1 kHz) and minimal line regulation (≤0.1 V over 10 µA–1 mA current range) support high-accuracy analog and memory retention functions.

The PLVA659AVL exhibits a hard, non-linear breakdown knee and low dynamic impedance (100 Ω typical), enabling fast transient response in low-current (<1 mA) stabilization roles. Its 0.9 nA reverse leakage at 50 % V_Z and 1.0 µA at 90 % V_Z confirm tight process control for low-power biasing applications.

Key Specifications

Parameter	Value and Actual Design Meaning
Nominal V_Z	5.90 V - precise regulation point at I_Z = 250 µA, ±0.20 V tolerance ensures stable reference under low-current conditions
Dynamic resistance R_Z	100 Ω - low impedance at 1 kHz AC superimposed on DC bias enables minimal output voltage variation during load transients
Reverse current I_R	0.9 nA at 50 % V_Z - ultra-low leakage preserves battery life in CMOS RAM backup circuits
Temperature coefficient S_Z	2.40 mV/K - predictable V_Z drift allows accurate compensation in temperature-sensitive references
Total power dissipation P_tot	250 mW - supports continuous operation on standard FR4 PCBs without forced cooling
Noise voltage density V_n	≤1.0 µV/√Hz at 1 kHz - 90 % lower than conventional series, critical for low-noise analog signal chains
Line regulation ΔV_Z	≤0.1 V from I_Z = 10 µA to 1 mA - maintains regulation accuracy across wide current range in variable-load systems

Pinout & Package

PLVA659AVL uses the SOT23 (TO-236AB) surface-mount plastic package: 3-pin, single-row, gull-wing leads, 1.9 mm × 1.3 mm footprint, 1.1 mm height, and 0.95 mm lead pitch. Thermal resistance is 500 K/W junction-to-ambient (free air) and 330 K/W junction-to-solder-point.

Pin/Terminal	Circuit Role	Design Meaning
1	Anode (A)	Forward-biased terminal; connects to lower-potential node in reverse-bias regulation configuration
2	Not Connected (n.c.)	Internally isolated; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress
3	Cathode (K)	High-impedance reference node; connected to regulated output and current-limiting resistor in shunt configuration

Key Features

Feature	Design Value
Hard breakdown knee	Sharp, non-linear transition into conduction improves regulation stability and reduces sensitivity to current variations
Very low dynamic impedance	100 Ω at 250 µA enables <0.1 V output shift under 100 µA load step-critical for low-power memory retention
Low noise performance	≤1.0 µV/√Hz at 1 kHz reduces interference in precision analog front-ends and sensor bias networks
Tight V_Z tolerance	±0.20 V at 5.90 V nominal ensures consistent system-level voltage margin without post-assembly trimming
Ultra-low reverse leakage	0.9 nA at 50 % V_Z minimizes standby current drain in battery-backed circuits over extended temperature ranges

Applications

CMOS RAM Backup

Voltage Stabilizer

Use Scenario: Maintaining data integrity in static RAM during main power loss using coin-cell or supercapacitor backup.

IC Role / Device Role / Timing Role: Shunt voltage reference providing stable 5.90 V bias to RAM V_CC pin during brown-out conditions.

Use Value: 0.9 nA reverse leakage extends backup runtime by >30 % versus conventional Zeners; hard knee prevents premature discharge.

Use Scenario: Regulating supply rail for low-current analog circuitry (e.g., op-amp bias, ADC reference) where LDO dropout is prohibitive.

IC Role / Device Role / Timing Role: Two-terminal shunt regulator replacing active regulators in space-constrained, low-quiescent-current designs.

Use Value: 100 Ω dynamic resistance delivers <0.1 V regulation error across 10 µA–1 mA load range-eliminating need for feedback loop compensation.

Voltage Limiter

Smoke Detector Relay Driver

Use Scenario: Clamping transient overvoltage on microcontroller I/O lines exposed to ESD or inductive kickback.

IC Role / Device Role / Timing Role: Fast-response avalanche clamp absorbing energy spikes while holding node voltage ≤6.10 V.

Use Value: 30 W non-repetitive peak power rating (100 µs pulse) protects downstream logic without sacrificing signal integrity during normal operation.

Use Scenario: Providing stable bias to electromechanical relay coil driver ICs in battery-powered smoke alarms.

IC Role / Device Role / Timing Role: Reference element ensuring consistent relay activation threshold despite battery voltage decay from 9 V to 6 V.

Use Value: 2.40 mV/K temperature coefficient enables predictable trip-point drift across –20 °C to +70 °C operating range-meeting UL 217 requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-voltage shunt regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C5V6	5.6 V nominal V_Z, 250 Ω R_Z, 100 nA I_R at 50 % V_Z, higher noise (≥3 µV/√Hz)	Higher leakage and impedance reduce battery life and regulation accuracy in RAM backup	Select only if 5.6 V regulation is acceptable and cost is primary constraint; not suitable for <1 µA standby designs
PLVA662AVL	6.20 V nominal V_Z, identical package/pinout, 0.9 nA I_R, 2.65 mV/K S_Z	Higher V_Z shifts regulation window; same thermal and noise performance	Use when system requires 6.2 V reference; direct drop-in replacement with no layout change but different voltage setpoint

Compared with BZX84-C5V6, PLVA659AVL offers 100× lower leakage and 2.5× lower dynamic resistance for superior low-power stability; versus PLVA662AVL, it provides a 300 mV lower regulation point with slightly better temperature coefficient for tighter voltage margins.

FAQ

What is the maximum continuous reverse power dissipation for PLVA659AVL?

The PLVA659AVL has a total power dissipation limit of 250 mW at T_amb = 25 °C on standard FR4 PCB. Its non-repetitive peak reverse power dissipation is rated at 30 W for 100 µs pulses at T_j = 150 °C, but sustained operation must remain within the 250 mW DC limit to avoid thermal runaway.

Can PLVA659AVL be used in place of a standard 5.6 V Zener diode?

No-it is not a direct substitute due to its 5.90 V nominal V_Z, tighter tolerance (±0.20 V), and significantly lower leakage (0.9 nA vs. typical 100 nA). Replacing a 5.6 V Zener requires verifying system voltage margins, load current, and temperature drift compatibility before integration.

How does the 2.40 mV/K temperature coefficient affect circuit design?

This coefficient means V_Z increases by 2.40 mV per Kelvin rise in junction temperature. Over a 50 °C range (25–75 °C), V_Z shifts by ~120 mV-requiring derating in high-temperature environments or inclusion of compensation resistors in precision reference networks.

Is PLVA659AVL automotive-qualified?

No-this part is non-automotive qualified per Revision History v.4 (January 2023). Nexperia explicitly states it is not tested or warranted for automotive use. For automotive applications, consult Nexperia's -Q qualified alternatives such as the PZTA659AQ series.
