Product details
Overview
PZU8.2BL,315 from Nexperia is a single Zener diode in SOD882 package designed for precision voltage regulation and overvoltage protection in space-constrained PCBs. It delivers 8.2 V nominal Zener voltage at 5 mA, ±5 % tolerance, 60 Ω maximum differential resistance, and supports 150 °C junction temperature operation in automotive-grade AEC-Q101 qualified construction.
For engineers reviewing the PZU8.2BL,315 datasheet, PZU8.2BL,315 pinout, PZU8.2BL,315 application, or PZU8.2BL,315 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (Rth(j-sp) = 55 K/W), non-repetitive surge capability (IZSM = 4.6 A), low reverse leakage (IR ≤ 0.5 μA at VR = 6.6 V), and compatibility with reflow-only soldering on FR4 PCBs.
Technical Context
The PZU8.2BL,315 operates as a two-terminal voltage reference device where reverse-biased breakdown provides stable clamping. Its SOD882 leadless package enables high-density placement while maintaining thermal performance via direct cathode pad conduction (Rth(j-sp) = 55 K/W).
It exhibits a positive temperature coefficient of +3.5 mV/K at IZ = 5 mA and diode capacitance of 10 pF at VR = 0 V, f = 1 MHz - characteristics critical for transient suppression and low-noise biasing in power management circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2,215 | Same 8.2 V nominal, ±5 %, but SOT23 package (larger footprint, higher Rth(j-a)) | Less suitable for ultra-dense layouts; lower surge rating (IZSM = 2.5 A) | Select when legacy SOT23 footprint compatibility or higher power derating margin is required |
| MMSZ5238B-7-F | 8.2 V nominal, ±5 %, SOD-123 package; higher Ptot (500 mW) but no AEC-Q101 qualification | Not approved for automotive use; higher thermal resistance limits high-temp reliability | Select for cost-sensitive industrial applications where automotive qualification is unnecessary |
Compared with BZX84-C8V2,215 and MMSZ5238B-7-F, the PZU8.2BL,315 uniquely combines AEC-Q101 qualification, ultra-small SOD882 footprint, and 4.6 A surge capability - making it optimal for next-generation automotive and portable electronics requiring both miniaturization and robustness.

FAQ
What is the Zener voltage tolerance of PZU8.2BL,315?
The PZU8.2BL,315 has a nominal Zener voltage of 8.2 V with a tolerance of ±5 %, meaning its actual breakdown voltage falls between 7.79 V and 8.61 V when measured at IZ = 5 mA and Tj = 25 °C. This tolerance is confirmed in Table 8 of the Nexperia datasheet and applies specifically to the 'B' variant denoted in the part number.
Is PZU8.2BL,315 qualified for automotive applications?
Yes, the PZU8.2BL,315 is AEC-Q101 qualified as explicitly stated in Section 8 ("Test information") of the official Nexperia datasheet. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and ESD - confirming suitability for under-hood and cabin automotive systems such as body control modules and infotainment power rails.
What is the maximum non-repetitive peak reverse current for PZU8.2BL,315?
The PZU8.2BL,315 supports a non-repetitive peak reverse current (IZSM) of 4.6 A under conditions of tp = 100 μs, square wave, and Tj = 25 °C prior to surge - directly extracted from Table 8 of the Nexperia datasheet. This value defines its transient overvoltage handling capability without permanent degradation.
Can PZU8.2BL,315 be hand-soldered?
No, the PZU8.2BL,315 is specified for reflow soldering only, as stated in Section 10 ("Soldering") of the datasheet. Its SOD882 leadless construction and thermal profile requirements make hand-soldering unreliable and unsupported; use of standard Pb-free reflow profiles with the recommended footprint (Fig. 9) is mandatory for reliable assembly.
What is the thermal resistance from junction to solder point for PZU8.2BL,315?
The thermal resistance from junction to solder point (Rth(j-sp)) for PZU8.2BL,315 is 55 K/W, as specified in Table 6 of the Nexperia datasheet. This parameter reflects heat transfer efficiency from the silicon die to the cathode solder joint and is critical for thermal design in high-ambient-temperature applications like automotive ECUs.
