Product details
Overview
PZU16B2,115 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 16 V at 5 mA with ±2 % tolerance (B2 grade), 80 Ω maximum differential resistance, and 12 V maximum reverse current at 1 μA - enabling stable low-power biasing in sensor interfaces and power supply feedback loops.
For engineers reviewing the PZU16B2,115 datasheet, PZU16B2,115 pinout, PZU16B2,115 application, or PZU16B2,115 equivalent, key selection criteria include its tight 16 V ±2 % Zener voltage tolerance, 310 mW total power dissipation at 25 °C ambient, SOD323F footprint compatibility, and thermal resistance of 400 K/W (junction-to-ambient, free air).
Technical Context
The PZU16B2,115 operates as a single-terminal voltage reference device with cathode-anode polarity defined by a marking bar. Its Zener breakdown mechanism provides stable reverse-bias regulation across −65 °C to +150 °C ambient temperature range, supported by a 150 °C maximum junction temperature rating.
It exhibits a positive temperature coefficient of +12.4 mV/K at IZ = 5 mA and 12 pF diode capacitance at 1 MHz/0 V, making it suitable for DC and low-frequency stabilization rather than high-speed signal clamping.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B16,115 | Same SOD323F package, ±2 % tolerance, but higher 90 Ω rdif and 50 nA IR at 12 V | Lower regulation precision and higher leakage reduce accuracy in high-impedance reference designs | Select when cost sensitivity outweighs need for lowest possible rdif and IR |
| MMSZ5245B-TP | SOD-123 package (larger), ±5 % tolerance (B grade), 17 Ω rdif, but only 100 nA IR at 12 V | Larger footprint limits use in ultra-dense layouts; wider tolerance requires system-level calibration | Choose for legacy board compatibility where SOD-123 is already allocated |
Compared with PZU16B2,115, BZX384-B16,115 trades regulation stability for broader availability, while MMSZ5245B-TP offers lower dynamic impedance but sacrifices package size and voltage tolerance - making PZU16B2,115 optimal for new designs prioritizing accuracy and miniaturization.

FAQ
What is the exact Zener voltage range for PZU16B2,115 at 5 mA test current?
The PZU16B2,115 has a guaranteed Zener voltage range of 15.37 V to 17.09 V when tested at IZ = 5 mA and Tj = 25 °C, reflecting its ±2 % B2 tolerance grade. This range is specified in Table 9 of the NXP PZUxB series datasheet and applies strictly to the PZU16B2,115 variant - not the broader PZU16B family.
Does PZU16B2,115 support reflow soldering, and what profile is recommended?
Yes, PZU16B2,115 supports only reflow soldering per NXP's official recommendation. The device is qualified for standard lead-free reflow profiles (J-STD-020), with peak temperature up to 260 °C. Its SOD323F package is designed for 4 mm pitch tape-and-reel handling (ordering code suffix -115), and the recommended footprint matches Figure 6 in the datasheet.
How does the temperature coefficient of PZU16B2,115 affect its regulation stability over temperature?
The PZU16B2,115 has a typical temperature coefficient of +12.4 mV/K at IZ = 5 mA, meaning its Zener voltage increases by ~12.4 mV per degree Celsius rise in junction temperature. This predictable positive drift allows designers to compensate for thermal effects in precision reference circuits - unlike lower-voltage Zeners that exhibit negative coefficients.
What is the maximum non-repetitive peak reverse current (IZSM) for PZU16B2,115?
The maximum non-repetitive peak reverse current for PZU16B2,115 is 5.5 A, measured under surge conditions of tp = 100 μs square wave with Tj = 25 °C prior to surge (Table 9, Note [2]). This rating defines transient overvoltage clamping capability, not continuous operation - sustained current must remain within the 310 mW DC power limit.
Can PZU16B2,115 be used in place of PZU16B,115 without layout changes?
Yes, PZU16B2,115 is pin-compatible and footprint-identical to PZU16B,115 - both use the SOD323F package with identical pin 1 (cathode) and pin 2 (anode) assignments. The only difference is tighter ±2 % voltage tolerance (B2) versus ±5 % (B), so no PCB modifications are required when upgrading for improved regulation accuracy.
