Product details
Overview
PZU6.2BA,115 from Nexperia is a general-purpose Zener voltage regulator diode in SOD323 (SC-76) package, designed for precision voltage reference and overvoltage protection in low-power analog circuits. It delivers a nominal Zener voltage of 6.2 V with ±5 % tolerance (Series B), differential resistance ≤80 Ω at IZ = 5 mA, reverse current ≤30 nA at IZ = 0.5 mA, and non-repetitive peak reverse power dissipation up to 40 W - enabling robust transient suppression in compact power rails.
For engineers reviewing the PZU6.2BA,115 datasheet, PZU6.2BA,115 pinout, PZU6.2BA,115 application, or PZU6.2BA,115 equivalent, this device is selected for stable low-current regulation, ESD-tolerant biasing, and noise-sensitive reference generation where tight voltage accuracy, low leakage, and fast breakdown knee are critical.
Technical Context
The PZU6.2BA,115 operates as a two-terminal shunt regulator with hard breakdown knee and intentional low dynamic impedance (≤80 Ω) at 5 mA, optimized for stable DC reference under light load. Its temperature coefficient is +2.7 mV/K at IZ = 5 mA, supporting predictable drift compensation in ambient ranges from –55 °C to +150 °C.
Thermal performance is defined by Rth(j-a) = 390 K/W (free air) and Rth(j-sp) = 55 K/W (solder point), confirming suitability for FR4 PCB mounting with standard SOD323 footprint. The device sustains 320 mW total power dissipation at Tamb ≤ 25 °C on single-sided tin-plated copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal, ±5 % tolerance - ensures predictable clamping threshold in 5 V–6.5 V rail supervision. |
| Differential Resistance (rdif) | ≤80 Ω at IZ = 5 mA - minimizes output voltage variation under small load changes. |
| Reverse Current (IR) | ≤30 nA at IZ = 0.5 mA - enables ultra-low standby power in battery-backed reference circuits. |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs - supports surge immunity against short-duration transients per IEC 61000-4-5. |
| Total Power Dissipation (Ptot) | 320 mW at Tamb ≤ 25 °C on FR4 PCB - defines continuous thermal limit for surface-mount reliability. |
| Junction Temperature (Tj) | –55 °C to +150 °C - validates operation across industrial and extended commercial environments. |
Pinout & Package
SOD323 (SC-76) plastic surface-mount package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode marked with bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; polarity marking bar identifies this terminal for correct PCB orientation. |
| 2 | Anode | Connected to ground or lower-potential rail; completes shunt path for Zener conduction during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Enables sharp, repeatable turn-on at 6.2 V - critical for accurate overvoltage detection without hysteresis. |
| Very low leakage current | ≤30 nA at 0.5 mA test current - preserves battery life and avoids loading in high-impedance sensor bias networks. |
| Low dynamic impedance | ≤80 Ω at 5 mA - maintains <±10 mV regulation error across ±1 mA load shifts in reference applications. |
| Optimized thermal resistance | Rth(j-sp) = 55 K/W - allows direct heat transfer from junction to solder pad, improving long-term stability under pulsed stress. |
Applications
| Power Supply Rail Clamp | ADC Reference Stabilization |
|---|---|
|
Use Scenario: Clamping 5 V logic supply against ESD or inductive kickback in microcontroller peripherals. IC Role / Device Role / Timing Role: Shunt regulator providing bidirectional overvoltage protection at the VCC node. Use Value: Limits transient excursions to ≤6.5 V (6.2 V + 5 %), preventing latch-up in 5 V CMOS I/O while drawing <1 µA at nominal operation. |
Use Scenario: Biasing precision ADC voltage reference input in portable data loggers. IC Role / Device Role / Timing Role: Low-drift Zener source delivering stable 6.2 V reference for ratiometric conversion. Use Value: Achieves <0.1 % line regulation error due to 80 Ω rdif, and contributes <0.05 ppm/°C system drift via +2.7 mV/K coefficient. |
| Low-Power Sensor Excitation | Interface Level Translation |
|
Use Scenario: Providing excitation voltage to resistive temperature detectors (RTDs) in wireless IoT nodes. IC Role / Device Role / Timing Role: Constant-voltage source powering 1 kΩ RTD bridge with minimal self-heating. Use Value: Delivers 6.2 V ±0.31 V with <30 nA leakage - eliminating measurement offset from parasitic current paths. |
Use Scenario: Translating 3.3 V GPIO signals to 5 V logic thresholds in mixed-voltage MCU systems. IC Role / Device Role / Timing Role: Passive level shifter using Zener clamp to define upper logic '1' threshold. Use Value: Sets reliable 6.2 V clamping ceiling that prevents 3.3 V driver saturation while maintaining <1 ns propagation delay. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B6V2 | Same 6.2 V ±5 %, but SOD-323 package with higher rdif (≤100 Ω) and higher IR (≤100 nA at 0.5 mA). | Less suitable for ultra-low-leakage biasing; acceptable for general-purpose clamping. | Select when cost sensitivity outweighs leakage or impedance requirements. |
| MMSZ5234B | 6.2 V ±5 % in SOD-123, larger footprint (3.7 mm × 1.6 mm), Ptot = 350 mW, rdif ≤ 10 Ω - lower impedance but higher capacitance (40 pF vs. 250 pF). | Better for high-frequency transient suppression; less space-efficient for dense layouts. | Select when board area permits and sub-10 Ω regulation stability is required. |
Compared with BZX384-B6V2, PZU6.2BA,115 offers 3× lower leakage and 20 % lower impedance for precision references; versus MMSZ5234B, it trades 10× smaller footprint and 250 pF lower capacitance for slightly higher rdif, favoring size-constrained, noise-sensitive designs.

FAQ
What is the maximum continuous forward current for PZU6.2BA,115?
The absolute maximum forward current is 200 mA per limiting values table. However, forward conduction is not its intended operating mode; sustained forward bias above 100 mA risks thermal overstress due to VF ≈ 1.1 V and limited Ptot = 320 mW. Designers should operate exclusively in reverse-biased Zener region.
Can PZU6.2BA,115 be used in place of a 6.2 V TL431-based shunt regulator?
No - the PZU6.2BA,115 is a passive two-terminal Zener diode without adjustable feedback or temperature-compensated reference architecture. It lacks the 2.5 V internal bandgap, programmable output, and 0.5 % initial accuracy of TL431. Use only where fixed 6.2 V clamping suffices and active regulation is unnecessary.
How does the +2.7 mV/K temperature coefficient affect long-term voltage stability?
At IZ = 5 mA, a +2.7 mV/K coefficient means VZ increases by 2.7 mV per °C rise in junction temperature. Over a 100 °C range (–25 °C to +75 °C ambient), this yields ~270 mV drift - acceptable for non-critical clamping but requires external compensation (e.g., NTC thermistor network) in metrology-grade references.
Is PZU6.2BA,115 qualified for automotive applications per AEC-Q200?
No - the datasheet states "non-automotive qualified products" and provides no AEC-Q200 stress test results. While rated for Tj = 150 °C and Tamb = –55 °C to +150 °C, it lacks automotive-specific qualification including vibration, humidity, and lifetime testing. Use only in industrial or consumer systems unless explicitly requalified.
