Product details
Overview
PZU10BL315 from Nexperia is a single Zener diode in SOD882 package, rated for 10 V nominal Zener voltage (±5 % tolerance), 250 mW total power dissipation at 25 °C ambient, and AEC-Q101 qualified for automotive use. It provides precise voltage regulation in compact space-constrained designs such as power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the PZU10BL315 datasheet, PZU10BL315 pinout, PZU10BL315 application, or PZU10BL315 equivalent, key selection criteria include its 10 V Zener voltage tolerance, 60 Ω maximum differential resistance at 5 mA, 7 μA maximum reverse current at 7.6 V, 110 A non-repetitive peak reverse current capability, and SOD882 thermal performance with Rth(j-sp) = 55 K/W.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage under varying load and temperature conditions. Its design supports low-noise regulation with typical temperature coefficient of +3.5 mV/K near 10 V and diode capacitance of 110 pF at 0 V.
The device uses silicon planar technology and features a leadless ultra-small SOD882 surface-mount package with cathode marked by a bar on top side. It is rated for junction temperatures up to 150 °C and ambient operating range from –55 °C to +150 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B10 | Same 10 V nominal, ±5 %, but in SOD323 package (1.7 × 1.3 mm); higher Ptot = 300 mW; no AEC-Q101 qualification | Not suitable for automotive under-hood use; larger footprint limits high-density layouts | Select when higher power margin is needed and automotive qualification is not required |
| MMSZ5240B | 10 V nominal, ±5 %, in SOD-123; Ptot = 350 mW; Rth(j-a) = 350 K/W (worse thermal performance); no AEC-Q101 | Higher thermal resistance reduces sustained power capability in compact PCBs | Choose for cost-sensitive consumer applications where thermal derating is acceptable |
Compared with BZX384-B10 and MMSZ5240B, PZU10BL315 delivers superior automotive reliability (AEC-Q101), tighter thermal path (Rth(j-sp) = 55 K/W), and smallest footprint (SOD882), making it optimal for space- and qualification-critical designs despite lower absolute power rating.

FAQ
What is the Zener voltage tolerance for PZU10BL315?
PZU10BL315 has a nominal Zener voltage of 10 V with ±5 % tolerance, meaning its actual breakdown voltage falls between 9.5 V and 10.5 V when tested at IZ = 5 mA and Tj = 25 °C. This tolerance is confirmed in Table 8 of the Nexperia datasheet and applies across the full operating temperature range.
Is PZU10BL315 qualified for automotive applications?
Yes, PZU10BL315 is AEC-Q101 qualified, as explicitly stated in Section 8 "Test information" of the official Nexperia product data sheet. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and other automotive-specific reliability requirements.
What is the maximum non-repetitive peak reverse current for PZU10BL315?
The maximum non-repetitive peak reverse current for PZU10BL315 is 110 A, measured under tp = 100 μs square-wave conditions with Tj = 25 °C prior to surge. This value is listed in Table 8 of the datasheet under the "Non-repetitive peak reverse current IZSM (A)" column for the 10 V variant.
What package type does PZU10BL315 use and how is polarity marked?
PZU10BL315 uses the SOD882 package - a leadless ultra-small surface-mount device measuring 1.02 mm × 0.62 mm × 0.46 mm. Polarity is marked by a bar on the top surface indicating Pin 1 (cathode), as shown in Figure 8 and Table 2 of the Nexperia datasheet.
What is the thermal resistance from junction to solder point for PZU10BL315?
The thermal resistance from junction to solder point (Rth(j-sp)) for PZU10BL315 is 55 K/W, specified in Table 6 of the Nexperia datasheet. This value assumes soldering at the cathode tab and reflects the dominant heat conduction path in typical PCB mounting.
