Product details
Overview
PZU9.1B2L from Nexperia is a single Zener diode in SOD882 package, designed for precision voltage regulation at 9.1 V nominal Zener voltage with ±2 % tolerance, 60 Ω maximum differential resistance at IZ = 5 mA, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PZU9.1B2L datasheet, PZU9.1B2L pinout, PZU9.1B2L application, or PZU9.1B2L equivalent, this device supports stable low-power voltage reference and overvoltage protection in space-constrained automotive and industrial PCBs where thermal performance and surge robustness matter.
Technical Context
The PZU9.1B2L operates as a two-terminal voltage reference diode with cathode-anode polarity, exhibiting sharp reverse breakdown at 9.1 V under 5 mA test current and maintaining low dynamic impedance (≤60 Ω) to ensure stable regulation across load variations.
It delivers non-repetitive peak reverse power dissipation up to 40 W (tp = 100 μs), total power dissipation of 250 mW on standard FR4 PCB, and junction temperature capability up to 150 °C - enabling reliable operation in thermally demanding environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C9V1 | ±5 % tolerance, SOT23 package (2.9 × 1.3 mm), higher rdif (≤90 Ω), not AEC-Q101 qualified | General-purpose industrial use only; unsuitable for automotive grade or tight-tolerance designs | Select when cost sensitivity outweighs accuracy and qualification requirements. |

FAQ
What is the Zener voltage tolerance of PZU9.1B2L?
The PZU9.1B2L has a nominal Zener voltage of 9.1 V with a tolerance of ±2 %, confirmed in Table 8 of the Nexperia datasheet under the "B2" selection code. This tight tolerance enables high-accuracy voltage references in feedback paths and analog circuits where regulation stability is critical. The PZU9.1B2L achieves this specification across its full operating temperature range without external calibration.
Is PZU9.1B2L qualified for automotive applications?
Yes, the PZU9.1B2L is AEC-Q101 qualified, as explicitly stated in Section 8 ("Test information") of the official Nexperia product data sheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD, confirming suitability for automotive powertrain, body control, and infotainment systems. The PZU9.1B2L meets the reliability requirements for deployment in production vehicles.
What is the maximum differential resistance of PZU9.1B2L at 5 mA?
The maximum differential resistance (rdif) of PZU9.1B2L is 60 Ω at IZ = 5 mA, per Table 8 in the Nexperia datasheet. This value reflects the slope of the Zener IV curve near the operating point and directly impacts regulation accuracy under varying load conditions. Lower rdif means less output voltage deviation - a key advantage of the PZU9.1B2L over wider-tolerance Zeners.
What package type does PZU9.1B2L use, and what are its dimensions?
The PZU9.1B2L uses the SOD882 package - a leadless ultra-small surface-mount plastic package measuring 1.02 mm × 0.62 mm × 0.47 mm (length × width × height), as shown in Figure 8 of the datasheet. Its cathode is marked by a visible bar on the top surface, and the exposed cathode pad enhances thermal conduction to the PCB. This footprint is significantly smaller than SOT23 or SOD-123 alternatives.
What is the non-repetitive peak reverse power rating for PZU9.1B2L?
The PZU9.1B2L has a non-repetitive peak reverse power dissipation (PZSM) rating of 40 W for pulse duration tp = 100 μs, as specified in Table 5 and illustrated in Figure 1 of the Nexperia datasheet. This rating enables effective clamping of short-duration transients such as ESD events or load-dump spikes without permanent degradation - a critical capability in automotive and industrial power interfaces.
