Product details
Overview
PZU3.6B2L from NXP Semiconductors is a precision ±2 % tolerance Zener diode in SOD882 ultra-small surface-mount package, rated for 3.6 V nominal breakdown voltage at 5 mA, 90 Ω differential resistance, and 5 µA reverse current at 1 V, used for voltage regulation and reference in space-constrained automotive and industrial power rails.
For engineers reviewing the PZU3.6B2L datasheet, PZU3.6B2L pinout, PZU3.6B2L application, or PZU3.6B2L equivalent, key selection criteria include its AEC-Q101 qualification, 250 mW total power dissipation at 25 °C ambient, 40 W non-repetitive peak reverse power capability, and SOD882 footprint compatibility with reflow-only assembly on FR4 PCBs.
Technical Context
The PZU3.6B2L operates as a single-terminal voltage reference device with cathode-anode polarity defined by a top-side marking bar. Its Zener breakdown mechanism delivers stable 3.6 V regulation under DC or pulsed reverse bias up to 40 W (100 µs square wave), with thermal resistance from junction to ambient of 500 K/W in free air and 250 K/W on standard FR4 PCB.
It exhibits a negative temperature coefficient of −2.4 mV/K at 5 mA, low 390 pF capacitance at 0 V, and is characterized for operation across −55 °C to +150 °C ambient range, supporting automotive-grade reliability requirements per AEC-Q101 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V6,115 | Same 3.6 V ±2 % rating but in SOD323 package (1.7 × 1.3 × 0.9 mm); higher 500 mW Ptot | Less space-constrained designs where larger footprint is acceptable | Select when higher continuous power margin is required and board area permits SOD323 |
| MMSZ4685T1G | 3.6 V ±5 % tolerance in SOD-123; 500 mW Ptot; not AEC-Q101 qualified | Consumer or industrial applications without automotive reliability requirements | Select for cost-sensitive non-automotive use where ±5 % tolerance is sufficient |
Compared with PZU3.6B2L, BZX384-B3V6 offers greater power headroom in a larger package, while MMSZ4685T1G provides lower cost at the expense of tolerance and qualification-making PZU3.6B2L optimal for space-limited, automotive-grade 3.6 V reference needs.

FAQ
What is the Zener voltage tolerance of the PZU3.6B2L?
The PZU3.6B2L has a ±2 % Zener voltage tolerance, indicated by the "B2" suffix in its part number. This means its nominal 3.6 V breakdown voltage is guaranteed between 3.55 V and 3.80 V at 5 mA test current, enabling tighter regulation than ±5 % variants like PZU3.6BL.
Is the PZU3.6B2L qualified for automotive applications?
Yes, the PZU3.6B2L is AEC-Q101 qualified per NXP's product data sheet Rev. 01 (2008). This certification confirms it meets stress-test requirements for discrete semiconductors used in automotive electronics, including temperature cycling, humidity bias, and mechanical shock testing.
What is the maximum continuous power dissipation for PZU3.6B2L?
The PZU3.6B2L has a total power dissipation limit of 250 mW at ambient temperatures ≤25 °C when mounted on a standard FR4 PCB with single-sided copper. Derating applies above 25 °C ambient, with junction temperature limited to 150 °C.
Can the PZU3.6B2L be hand-soldered?
No-reflow soldering is the only recommended method for PZU3.6B2L, as stated in the official NXP data sheet. Hand-soldering or wave soldering risks thermal damage due to the SOD882 package's sensitivity and lack of thermal mass; reflow profiles must follow JEDEC J-STD-020 guidelines.
How is the cathode identified on the PZU3.6B2L package?
The cathode of the PZU3.6B2L is identified by a visible marking bar on the top surface of the SOD882 package. Pin 1 (cathode) and Pin 2 (anode) are defined in the data sheet's pinning diagram, with the bar aligned over the cathode terminal in top-view orientation.
