Product details
Overview
PZU8.2B1A,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 8.2 V nominal working voltage, 320 mW total power dissipation, and 5 A non-repetitive peak reverse current at 100 µs pulse width-used for precision voltage reference and overvoltage protection in low-power analog sensor interfaces.
For engineers reviewing the PZU8.2B1A,115 datasheet, PZU8.2B1A,115 pinout, PZU8.2B1A,115 application, or PZU8.2B1A,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), differential resistance (≤60 Ω at IZ = 5 mA), reverse leakage (≤10 nA at IZ = 0.5 mA), thermal resistance (255 K/W junction-to-solder point), and SOD323 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC reference voltage under varying load and temperature conditions. Its hard breakdown knee and low dynamic impedance (60 Ω typical at 5 mA) ensure minimal output voltage drift during transient current changes.
Designed for surface-mount applications, it features intentional minor leakage current rise to reduce switching noise and improve transient response-verified per Application Note AN90031-while maintaining 150 °C maximum junction temperature and −55 °C to +150 °C ambient operating range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B8V2 | Same 8.2 V ±2 % rating but SOD123 package (2.1 mm × 1.3 mm); 400 mW Ptot; higher rdif (90 Ω) | Less suitable for ultra-dense layouts; better thermal margin in moderate-power designs | Select when board space permits larger footprint and higher continuous power is required |
| MMSZ5233B | 8.2 V ±5 % (B series); SOD123; 500 mW Ptot; rdif = 100 Ω; no optimized leakage profile | Acceptable for non-critical references; unsuitable for low-noise or low-leakage signal chains | Choose only for cost-sensitive, non-precision applications where ±5 % tolerance is acceptable |
Compared with BZX384-B8V2 and MMSZ5233B, PZU8.2B1A,115 delivers tighter tolerance, lower dynamic impedance, and purpose-tuned leakage-making it optimal for space-constrained, low-noise, and battery-sensitive designs where regulation accuracy and thermal efficiency are prioritized.

FAQ
What is the maximum continuous reverse current for PZU8.2B1A,115 at 25 °C ambient?
The device does not specify a maximum continuous reverse current; instead, its safe operating area is defined by total power dissipation (320 mW at Tamb ≤ 25 °C on FR4 PCB). At 8.2 V Zener voltage, this corresponds to ~39 mA average reverse current under steady-state conditions-exceeding this risks thermal overload and parameter shift.
Can PZU8.2B1A,115 be used in place of a 5.1 V Zener diode?
No-PZU8.2B1A,115 is a fixed 8.2 V Zener diode with ±2 % tolerance and cannot substitute for a 5.1 V device without circuit redesign. Its voltage regulation window (7.99–8.37 V) does not overlap the 5.1 V range, and using it would cause incorrect biasing or overvoltage damage in 5.1 V-dependent circuits.
Is PZU8.2B1A,115 qualified for automotive applications?
No-this part is not automotive-qualified. The datasheet explicitly states that unless otherwise specified, Nexperia products like PZU8.2B1A,115 are not tested or warranted for automotive use, including AEC-Q101 stress testing or temperature cycling across −40 °C to +125 °C extended range.
How does the SOD323 package affect thermal performance compared to SOD123?
SOD323 has higher thermal resistance: Rth(j-a) = 390 K/W (free air) vs. ~250 K/W for SOD123. On PCB, Rth(j-sp) is 255 K/W-still higher than typical SOD123 values (~180 K/W)-meaning PZU8.2B1A,115 runs hotter under identical power, requiring careful copper pour design to avoid exceeding 150 °C junction temperature.
