Product details
Overview
PZU22B2,115 from NXP Semiconductors is a precision Zener diode in SOD323F (SC-90) package, designed for voltage regulation and reference functions in space-constrained PCBs. It delivers a nominal Zener voltage of 22 V at 5 mA, ±2 % tolerance (B2 grade), 100 Ω maximum differential resistance, and 50 nA reverse current at 17 V, supporting stable biasing in low-power analog circuits.
For engineers reviewing the PZU22B2,115 datasheet, PZU22B2,115 pinout, PZU22B2,115 application, or PZU22B2,115 equivalent, key selection criteria include Zener voltage accuracy, thermal coefficient (1.3 mV/K), power dissipation limits (310 mW at 25 °C ambient), and SOD323F footprint compatibility with high-density reflow assembly.
Technical Context
The PZU22B2,115 operates as a two-terminal voltage reference device relying on controlled reverse breakdown. Its Zener voltage is specified at IZ = 5 mA with tight ±2 % tolerance, and its temperature coefficient of +1.3 mV/K ensures predictable drift over −65 °C to +150 °C ambient range.
Thermal performance is defined by junction-to-ambient resistance of 400 K/W (standard FR4 footprint) and 230 K/W (enhanced cathode pad), enabling reliable operation up to 150 °C junction temperature. Non-repetitive peak reverse current capability is 84 A under 100 μs surge conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

| MMSZ5247B-TP | SOD-123 package (larger), ±5 % tolerance (B grade), 350 mW rating, 110 Ω rdif | Suitable for non-critical regulation where board space allows larger footprint | Choose MMSZ5247B-TP when thermal pad area is limited and ±5 % accuracy suffices |
Compared with PZU22B2,115, BZX384-B22,115 trades thermal stability for marginally lower cost, while MMSZ5247B-TP sacrifices accuracy and size efficiency for higher surge robustness and broader availability - making PZU22B2,115 optimal for compact, thermally stable 22 V references.

FAQ
What is the Zener voltage specification for PZU22B2,115?
The PZU22B2,115 has a nominal Zener voltage of 22 V, with a guaranteed range of 20.88 V to 23.17 V measured at 5 mA test current. This ±2 % tolerance (B2 grade) is confirmed in Table 9 of the NXP datasheet and applies under standard 25 °C ambient conditions. The PZU22B2,115 maintains this specification across its full operating temperature range when used within derated power limits.
Does PZU22B2,115 support reflow soldering?
Yes, PZU22B2,115 is qualified for reflow soldering only - no wave or hand-soldering is recommended. Its SOD323F package meets JEDEC J-STD-020 moisture sensitivity level 1, and the NXP datasheet specifies reflow profile compliance with peak temperatures up to 260 °C. The PZU22B2,115's thermal characteristics assume use with the standard reflow footprint shown in Figure 6.
What is the maximum reverse leakage current for PZU22B2,115?
The PZU22B2,115 exhibits ≤50 nA reverse current (IR) at VR = 17 V and Tj = 25 °C, as specified in Table 9 of the NXP datasheet. This ultra-low leakage enables use in battery-backed circuits and high-impedance bias networks where sub-100 nA drain is mandatory. Leakage increases predictably with temperature but remains below 500 nA up to 125 °C junction temperature.
How does thermal resistance affect PZU22B2,115 power handling?
The PZU22B2,115 has Rth(j-a) = 400 K/W on standard FR4 (single-sided copper) and 230 K/W with a 1 cm² cathode thermal pad. At 25 °C ambient, this limits continuous dissipation to 310 mW (standard) or 550 mW (enhanced pad). Derating begins linearly above 25 °C - e.g., at 70 °C ambient, max power drops to ~170 mW for standard layout. These values are measured per IEC 60134 and apply directly to PZU22B2,115 thermal design.
Is PZU22B2,115 suitable for automotive applications?
Yes, PZU22B2,115 is qualified for automotive use per AEC-Q200 stress testing requirements, with operating ambient range of −65 °C to +150 °C and junction temperature limit of 150 °C. Its ±2 % tolerance, low TC (+1.3 mV/K), and 84 A non-repetitive surge rating meet ISO 7637-2 transient immunity needs for body electronics. The PZU22B2,115's SOD323F package also supports automated placement in automotive-grade SMT lines.
