Product details
Overview
PZU8.2BA,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 and digital circuits. It delivers a nominal Zener voltage of 8.2 V with ±5 % tolerance (Series B), differential resistance ≤60 Ω at IZ = 5 mA, reverse current ≤10 nA at IZ = 0.5 mA, and non-repetitive peak reverse power dissipation up to 40 W - enabling robust transient suppression in compact DC bias networks.
For engineers reviewing the PZU8.2BA,115 datasheet, PZU8.2BA,115 pinout, PZU8.2BA,115 application, or PZU8.2BA,115 equivalent, key selection criteria include its 8.2 V regulation accuracy, low leakage at sub-1 µA levels, hard breakdown knee, thermal coefficient of +4.6 mV/K, and compatibility with standard reflow soldering footprints for high-density PCB layouts.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable voltage across load variations and supply fluctuations. Its design targets low-current regulation (IZ = 0.5–5 mA), with specified differential resistance and temperature coefficient optimized for stability in ambient ranges from –55 °C to +150 °C.
The device features intentional minor leakage rise for improved switching speed and noise reduction per AN90031, and achieves junction-to-solder-point thermal resistance of 55 K/W when mounted on FR4 with 1 cm² cathode pad - supporting reliable operation under pulsed surge conditions up to 100 µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.2 V nominal, ±5 % tolerance - ensures predictable clamping level in voltage reference and protection circuits |
| Differential Resistance (rdif) | ≤60 Ω at IZ = 5 mA - minimizes output voltage deviation under load current changes |
| Reverse Current (IR) | ≤10 nA at IZ = 0.5 mA - enables ultra-low quiescent power consumption in battery-sensitive designs |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - supports transient surge suppression without thermal runaway |
| Total Power Dissipation (Ptot) | 320 mW at Tamb ≤ 25 °C on FR4 - defines continuous DC power handling in standard PCB mounting |
| Temperature Coefficient (SZ) | +4.6 mV/K - quantifies voltage drift per degree Celsius, critical for temperature-stable references |
| Junction Temperature (Tj) | 150 °C maximum - sets upper thermal limit for reliability in enclosed or high-ambient environments |
Pinout & Package
The PZU8.2BA,115 is housed in a SOD323 (SC-76) surface-mount plastic package measuring 1.7 mm × 1.25 mm × 0.95 mm, with 1.3 mm lead pitch and cathode marked by a bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; polarity marker determines correct orientation for reverse-bias operation |
| 2 | Anode | Connected to ground or lower-potential rail; completes bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Ensures sharp, predictable turn-on at 8.2 V - improves regulation accuracy in low-current bias networks |
| Very low dynamic impedance | 60 Ω at 5 mA enables tight voltage control under varying load conditions in reference circuits |
| Optimized leakage for noise reduction | Controlled 10 nA reverse current balances low-power operation with faster transient response per AN90031 |
| SOD323 footprint compatibility | Standardized 1.3 mm pitch and 1.7 × 1.25 mm body allows automated placement and reflow in high-volume manufacturing |
Applications
| Power Supply Rail Clamp | ADC Reference Stabilization |
|---|---|
|
Use Scenario: Clamping 12 V input rail to protect downstream 8.2 V-tolerant logic or analog ICs from overvoltage transients. IC Role / Device Role / Timing Role: Zener diode acts as shunt regulator, conducting excess current when rail exceeds 8.2 V ±5 %. Use Value: Limits voltage excursions to within safe operating range using only passive components, eliminating need for active supervision circuitry. |
Use Scenario: Providing stable 8.2 V reference for 10-bit ADC biasing in sensor signal conditioning front-ends. IC Role / Device Role / Timing Role: Functions as precision voltage source for ADC internal reference divider or external buffer stage. Use Value: Delivers <10 nA leakage and +4.6 mV/K tempco - enabling <±0.5 LSB error contribution over 0–70 °C ambient range. |
| Microcontroller Reset Circuit | Low-Power Sensor Bias Network |
|
Use Scenario: Generating clean reset threshold for 3.3 V microcontrollers using resistor-divider + Zener clamp topology. IC Role / Device Role / Timing Role: Sets accurate trip point for RC-based reset generator by fixing upper voltage rail at 8.2 V. Use Value: ±5 % tolerance and hard knee ensure consistent reset assertion timing across production units and temperature. |
Use Scenario: Biasing photodiode or thermistor amplifier stages in battery-powered IoT nodes requiring <1 µA standby current. IC Role / Device Role / Timing Role: Supplies regulated 8.2 V to op-amp rails while contributing negligible leakage to sensing node. Use Value: 10 nA reverse current at 0.5 mA test condition directly supports sub-µA system sleep modes without reference drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B8V2 | Same 8.2 V ±5 %, but SOD323 package with higher rdif (≤90 Ω) and higher IR (≤100 nA at 0.5 mA) | Less suitable for ultra-low-leakage bias networks; acceptable for general-purpose clamping | Select when cost sensitivity outweighs leakage or impedance requirements |
| MMSZ4687T1G | 8.2 V ±5 %, SOD123 package (larger footprint), rdif ≤70 Ω, IR ≤100 nA at 1 V | Requires board redesign due to different package; higher thermal resistance limits pulsed power handling | Choose only if SOD123 is already standardized in design and 40 W surge rating is not required |
Compared with BZX384-B8V2 and MMSZ4687T1G, PZU8.2BA,115 offers superior low-current regulation performance (60 Ω rdif, 10 nA IR) and higher surge capability (40 W), making it optimal for space-constrained, low-leakage, and transient-resilient applications where SOD323 is preferred.

FAQ
What is the maximum continuous power dissipation for PZU8.2BA,115?
The total power dissipation (Ptot) is rated at 320 mW when mounted on an FR4 PCB with single-sided copper, tin-plated, and standard SOD323 footprint at Tamb ≤ 25 °C. Derating is required above this ambient temperature per the thermal resistance of 255 K/W junction-to-ambient.
How does the temperature coefficient affect regulation accuracy over temperature?
PZU8.2BA,115 has a positive temperature coefficient of +4.6 mV/K, meaning its Zener voltage increases by approximately 4.6 mV per degree Celsius rise. Over a 0–70 °C ambient range, this results in ~322 mV total drift - a key factor when designing temperature-critical references or compensation networks.
Can PZU8.2BA,115 be used in place of a 5.1 V Zener for higher-voltage biasing?
No - PZU8.2BA,115 is a fixed 8.2 V Zener and cannot substitute for a 5.1 V device without circuit redesign. Its voltage tolerance (±5 %), differential resistance, and leakage profile are specific to 8.2 V operation; using it at other voltages violates absolute maximum ratings and invalidates regulation behavior.
Is the SOD323 package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies full compatibility with JEDEC J-STD-020D reflow profiles. The recommended footprint (Fig. 10) uses 0.5 mm × 0.6 mm solder lands with 0.6 mm solder resist opening, supporting peak temperatures up to 260 °C and ensuring reliable interconnect integrity in automated assembly.
