Product details
Overview
PZU16B1A,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 16 V nominal working voltage, 320 mW total power dissipation, and 12 A non-repetitive peak reverse current at 100 µs pulse width. It delivers low dynamic impedance (80 Ω max at IZ = 5 mA), tight voltage regulation, and optimized noise performance for precision reference and overvoltage protection in compact DC power rails.
For engineers reviewing the PZU16B1A,115 datasheet, PZU16B1A,115 pinout, PZU16B1A,115 application, or PZU16B1A,115 equivalent, this device is selected for stable 16 V clamping in space-constrained consumer, industrial, and communication power management circuits where ±2 % initial tolerance and low leakage (<20 nA at 0.5 mA) are critical.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 16 V reference across its cathode–anode terminals under regulated current conditions. Its differential resistance of ≤80 Ω at 5 mA ensures minimal voltage shift with load variation, while its temperature coefficient of +1.5 mV/K (typical) provides predictable drift behavior over temperature.
The device is designed for surface-mount operation on FR4 PCBs with standard SOD323 footprint, featuring hard breakdown knee characteristics and intentional low leakage for noise-sensitive applications. Thermal resistance from junction to solder point is 55 K/W, enabling reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 16 V - precise clamping threshold for 15.35–16.65 V range at IZ = 5 mA |
| Tolerance | ±2 % - B1 series grade enables tighter regulation than ±5 % alternatives |
| Differential Resistance | ≤80 Ω at IZ = 5 mA - minimizes output voltage variation under dynamic load changes |
| Reverse Current | ≤20 nA at VR = 0.5 × VZ - ultra-low leakage preserves battery life and signal integrity |
| Total Power Dissipation | 320 mW at Tamb ≤ 25 °C - defines continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Current | 12 A at tp = 100 µs - supports transient surge suppression without damage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16,215 | ±5 % tolerance, higher rdif (100 Ω), 250 mW Ptot, same SOT23 package | Lower accuracy and power handling; suitable only for non-critical clamping | Select when cost sensitivity outweighs regulation precision and thermal margin |
| MMSZ5245B-7-F | ±5 % tolerance, 500 mW Ptot, SOD-123 package (larger footprint) | Higher power but less board-area efficient; requires different PCB land pattern | Choose when >320 mW continuous dissipation is required and space permits larger package |
Compared with BZX84-C16,215 and MMSZ5245B-7-F, PZU16B1A,115 offers superior voltage accuracy (±2 % vs ±5 %), lower dynamic impedance (80 Ω vs 100 Ω/60 Ω), and optimal SOD323 footprint for high-density designs-making it preferred for precision reference and space-constrained surge protection.

FAQ
What is the maximum continuous reverse current for PZU16B1A,115 at 25 °C ambient?
The device has no specified maximum continuous reverse current; instead, its safe operating area is defined by total power dissipation (320 mW at Tamb ≤ 25 °C). At 16 V Zener voltage, this corresponds to ~20 mA average reverse current on FR4 PCB with standard footprint. Exceeding this risks thermal runaway due to junction temperature rise beyond 150 °C.
Does PZU16B1A,115 meet automotive AEC-Q200 requirements?
No. PZU16B1A,115 is not AEC-Q200 qualified and is explicitly designated for industrial and consumer applications. Nexperia's datasheet states "non-automotive qualified products" and prohibits use in safety-critical automotive systems. For automotive-grade Zeners, consult Nexperia's AEC-Q200-certified PZUxHBA series.
How does the B1 tolerance series differ from B2 or B3 in the PZUxBA family?
B1 denotes ±2 % initial tolerance at IZ = 5 mA, while B2 and B3 also specify ±2 % but apply to different nominal voltage ranges: B2 covers 11–24 V types, B3 covers 27–51 V types. PZU16B1A,115 uses B1 because 16 V falls within the 11–24 V band assigned to B2-but the marking code table confirms "PZU16*A" maps to B1 (X1), not B2 (X2), indicating Nexperia's specific binning assignment for this voltage point.
Can PZU16B1A,115 be used in parallel for higher power handling?
No. Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, slight VZ mismatches cause current hogging. Parallel operation is not recommended unless actively balanced with series resistors-Nexperia's datasheet provides no derating guidance or characterization for paralleling, and thermal coupling limitations make it unreliable for sustained power sharing.
