Product details
Overview
PZU15B,115 from NXP Semiconductors is a single Zener diode in SOD323F (SC-90) surface-mount package, designed for precision voltage regulation at 15 V nominal Zener voltage with ±5 % tolerance, 80 Ω maximum differential resistance at IZ = 5 mA, and 310 mW total power dissipation at Tamb ≤ 25 °C. It serves as a stable reference or clamp in low-power analog supply rails and signal conditioning circuits.
For engineers reviewing the PZU15B,115 datasheet, PZU15B,115 pinout, PZU15B,115 application, or PZU15B,115 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (Rth(j-a) = 400 K/W on FR4), reverse current (IR ≤ 15 nA at VR = 11 V), temperature coefficient (+2 mV/K), and SOD323F footprint compatibility.
Technical Context
The PZU15B,115 operates as a two-terminal voltage reference device, conducting in reverse breakdown to maintain a stable 15 V across its terminals when biased above its knee current (IZK ≈ 0.5 mA). Its Zener mechanism dominates conduction above ~5 V, yielding a positive temperature coefficient of +2 mV/K at IZ = 5 mA.
It exhibits low dynamic impedance (rdif ≤ 80 Ω), enabling effective ripple suppression in shunt regulator topologies. Thermal performance is defined for standard FR4 PCB mounting (Rth(j-a) = 400 K/W) and enhanced cathode pad layout (Rth(j-a) = 230 K/W), supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 13.84 V to 15.52 V at IZ = 5 mA - defines regulation window for precision 15 V reference applications |
| Differential Resistance rdif | ≤80 Ω at IZ = 5 mA - ensures low output impedance for stable voltage under load variation |
| Reverse Current IR | ≤15 nA at VR = 11 V - minimizes quiescent power loss in high-impedance bias networks |
| Temperature Coefficient SZ | +2 mV/K at IZ = 5 mA - enables predictable drift compensation in temperature-sensitive circuits |
| Total Power Dissipation Ptot | 310 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 layout |
| Junction Temperature Tj | −65 °C to +150 °C - supports operation in extended industrial ambient environments |
| Forward Voltage VF | ≤1.1 V at IF = 100 mA - limits forward conduction loss during transient overvoltage events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15 | Same 15 V nominal, ±5 % tolerance, but SOT-23 package (3.0 × 1.4 mm); higher Rth(j-a) = 450 K/W | Less suitable for ultra-dense layouts; requires larger PCB area and delivers lower power derating | Choose BZX84-C15 only if SOT-23 is already standardized in design and thermal margin >100 mW is available |
| MMSZ5245B | 15 V nominal, ±5 %, SOD-123 package (3.7 × 1.6 mm); rdif = 17 Ω (lower), but IR = 100 nA at 11 V (higher) | Better regulation stability but higher leakage compromises low-power monitoring accuracy | Select MMSZ5245B where dynamic impedance is critical and leakage <50 nA is acceptable |
Compared with BZX84-C15 and MMSZ5245B, the PZU15B,115 offers optimal balance of compact SOD323F size, low leakage (15 nA), and adequate dynamic impedance (80 Ω) for general-purpose 15 V regulation-making it preferred for space-constrained, low-quiescent-current designs.

FAQ
What is the exact Zener voltage range for PZU15B,115 at 5 mA test current?
The PZU15B,115 has a guaranteed Zener voltage range of 13.84 V to 15.52 V when measured at IZ = 5 mA and Tj = 25 °C, per Table 9 of the NXP datasheet. This ±5 % tolerance band reflects the "B" grade designation and is validated for every unit in production screening.
Does PZU15B,115 support reflow soldering, and what profile is recommended?
Yes, PZU15B,115 is qualified for lead-free reflow soldering only-wave or hand soldering is not recommended. The NXP datasheet specifies JEDEC J-STD-020-compliant profiles with peak temperature ≤260 °C and time above 217 °C limited to 60–150 seconds, matching standard Pb-free assembly processes.
How does the thermal resistance of PZU15B,115 change with PCB layout?
PZU15B,115 exhibits Rth(j-a) = 400 K/W on standard FR4 (single-sided copper, tin-plated, no thermal pad) and improves to 230 K/W when the cathode pad is enlarged to 1 cm². This 42 % reduction directly increases allowable continuous power from 310 mW to 550 mW at Tamb = 25 °C.
What is the maximum reverse leakage current for PZU15B,115 at 11 V?
At VR = 11 V and Tj = 25 °C, the PZU15B,115 guarantees reverse leakage current ≤15 nA, as specified in Table 9. This value is measured under DC conditions and remains stable across its full operating temperature range (−65 °C to +150 °C).
Can PZU15B,115 be used in bidirectional clamping configurations?
Yes, PZU15B,115 functions bidirectionally: it clamps in reverse breakdown at ~15 V and conducts forward at ≤0.9 V (at IF = 10 mA). This dual-mode behavior enables symmetric clamping between −0.9 V and +15 V, useful for protecting mixed-signal nodes against both negative transients and positive overvoltages.
