Product details
Overview
PZU3.6B1A,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 3.6 V nominal working voltage at 5 mA, with 90 Ω maximum differential resistance and 5 µA reverse current at 0.5 mA test condition, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the PZU3.6B1A,115 datasheet, PZU3.6B1A,115 pinout, PZU3.6B1A,115 application, or PZU3.6B1A,115 equivalent, this part supports stable regulation in space-constrained PCBs where tight voltage tolerance, low leakage, and hard breakdown knee are required for sensor biasing and ADC reference stabilization.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 3.6 V reference across its cathode-anode terminals under controlled current conditions. Its ±2 % tolerance (B1 series), 90 Ω typical dynamic impedance at IZ = 5 mA, and 5 µA IR at IZ = 0.5 mA enable accurate regulation in low-current analog signal chains.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it delivers 320 mW total power dissipation at Tamb ≤ 25 °C and withstands non-repetitive 40 W surge pulses (tp = 100 µs), making it suitable for transient-suppressed reference nodes in industrial control and portable instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 3.6 V at IZ = 5 mA - defines precise regulation point for reference circuit design |
| Tolerance | ±2 % (B1 series) - ensures voltage accuracy within ±0.072 V for high-fidelity biasing |
| Differential Resistance | ≤90 Ω at IZ = 5 mA - minimizes output voltage shift under load current variation |
| Reverse Current | 5 µA at IZ = 0.5 mA - enables ultra-low quiescent power consumption in battery-powered systems |
| Total Power Dissipation | 320 mW at Tamb ≤ 25 °C - sets thermal limit for continuous operation on standard FR4 layout |
| Non-repetitive Peak Power | 40 W for tp = 100 µs - provides surge immunity against ESD and switching transients |
| Junction Temperature | −55 °C to +150 °C - supports operation in extended industrial ambient environments |
Pinout & Package
The PZU3.6B1A,115 is housed in a SOD323 (SC-76) plastic surface-mount package measuring 1.7 mm × 1.25 mm × 0.95 mm, with 1.3 mm lead pitch and tin-plated terminations compatible with reflow and wave soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode | Connected to ground or current-limiting resistor; reverse-bias polarity must be observed for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Sharp, well-defined Zener transition improves regulation stability at low currents (e.g., <1 mA) |
| Low dynamic impedance | 90 Ω max at 5 mA enables minimal voltage deviation under varying load conditions |
| Ultra-low leakage | 5 µA IR at 0.5 mA supports microamp-level standby operation without reference drift |
| Small-outline packaging | SOD323 footprint saves >60 % board area vs. DO-35, enabling dense mixed-signal layouts |
| Thermal robustness | Rth(j-a) = 390 K/W allows reliable operation up to 150 °C junction temperature |
Applications
| Industrial Sensor Signal Conditioning | Portable Device Voltage Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V6,115 | Same SOD323 package and 3.6 V nominal, but ±5 % tolerance (B grade) and higher 100 µA IR at 1 V | Lower accuracy and higher leakage reduce suitability for precision reference use | Select when cost sensitivity outweighs voltage stability requirements |
| MMSZ4682T1G | 3.6 V nominal, ±5 % tolerance, SOD-123 package (larger footprint), 100 µA IR at 1 V, 500 mW Ptot | Higher power rating but looser tolerance and larger board area requirement | Prefer for higher-power regulation where SOD-123 layout is already standardized |
Compared with BZX384-B3V6,115 and MMSZ4682T1G, PZU3.6B1A,115 offers tighter ±2 % tolerance and lower 5 µA leakage-critical for battery-powered reference designs-while maintaining identical SOD323 footprint and 320 mW thermal envelope.

FAQ
What is the maximum continuous reverse current for PZU3.6B1A,115 at 25 °C ambient?
The device supports a maximum forward current of 200 mA, but as a Zener regulator, its continuous reverse (Zener) current is limited by power dissipation. At 25 °C ambient on standard FR4, 320 mW / 3.6 V ≈ 89 mA is the practical upper limit for sustained Zener conduction without exceeding thermal limits.
Does PZU3.6B1A,115 have automotive qualification?
No. The PZU3.6B1A,115 is not AEC-Q200 qualified and lacks automotive-specific testing or screening. It is intended for industrial, consumer, and computing applications. For automotive use, Nexperia offers separate AEC-Q200-compliant Zener families such as the PZUxHBA series.
How does the B1 tolerance grade differ from B grade in the PZUxBA series?
B1 denotes ±2 % tolerance at IZ = 5 mA, while B grade specifies approximately ±5 %. For PZU3.6B1A,115, this means a guaranteed Zener voltage range of 3.528 V to 3.672 V versus 3.42 V to 3.78 V for the B-grade variant-enabling tighter system-level voltage margining.
Can PZU3.6B1A,115 be used in parallel for higher power handling?
No. Zener diodes exhibit negative temperature coefficients below ~5 V and mismatched characteristics; paralleling causes current hogging and thermal runaway. For higher power, use a single higher-rated Zener or switch to an active shunt regulator topology with external pass transistor.
