Product details
Overview
PDZ15B/S911115 from Nexperia is a single Zener diode in SOD323 (SC-76) surface-mount package, designed for low-power voltage regulation at nominal 15 V with ±2 % tolerance, 80 Ω max differential resistance at 5 mA, and 0.05 μA max reverse leakage at 11.0 V. It delivers stable reference voltage in compact power management circuits for consumer and industrial electronics.
For engineers reviewing the PDZ15B/S911115 datasheet, PDZ15B/S911115 pinout, PDZ15B/S911115 application, or PDZ15B/S911115 equivalent, key selection criteria include Zener voltage accuracy, low leakage at rated VR, thermal resistance (Rth(j-a) = 340 K/W), and compatibility with reflow/wave soldering footprints per JEDEC SC-76 standards.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage across varying load currents. Its hard breakdown knee and low dynamic impedance (80 Ω typical at IZ = 5 mA) ensure precise regulation under light-load conditions common in biasing and sensing circuits.
Thermal performance is defined for FR4 PCB mounting with single-sided copper: junction-to-ambient thermal resistance is 340 K/W, and maximum junction temperature is +150 °C. Power dissipation derates linearly above 25 °C ambient, reaching zero at ~150 °C per Fig. 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.34 V to 14.98 V at IZ = 5 mA - tight 15 V nominal regulation window suitable for precision reference applications |
| Differential Resistance (rdif) | 80 Ω max at IZ = 5 mA - ensures minimal output voltage shift under small current variations |
| Reverse Leakage (IR) | 0.05 μA max at VR = 11.0 V - enables ultra-low quiescent current operation in battery-sensitive designs |
| Power Dissipation (Ptot) | 400 mW max at Tamb ≤ 25 °C - supports continuous operation in space-constrained SMD layouts |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines low-loss conduction when used in forward-biased protection paths |
| Temperature Coefficient (SZ) | 11.4 mV/K typical at IZ = 5 mA - quantifies voltage drift with junction temperature for thermal stability analysis |
| Junction-to-Ambient Rth | 340 K/W - determines required PCB copper area and airflow for thermal compliance in sealed enclosures |

FAQ
What is the Zener voltage tolerance for PDZ15B/S911115?
The PDZ15B/S911115 has a Zener voltage tolerance of approximately ±2 %, specified as 14.34 V to 14.98 V at test current IZ = 5 mA. This tight tolerance enables reliable use in applications demanding accurate voltage references without external calibration, such as feedback networks and analog sensor biasing circuits where PDZ15B/S911115 serves as the primary regulation element.
How does PDZ15B/S911115 perform thermally on a standard PCB?
When mounted on an FR4 PCB with single-sided copper and standard SOD323 footprint, PDZ15B/S911115 exhibits a junction-to-ambient thermal resistance (Rth(j-a)) of 340 K/W. Its power dissipation derates linearly above 25 °C ambient, reaching zero at ~150 °C. This behavior is documented in Figure 1 of the datasheet and directly impacts sustained current capability in enclosed or high-temperature environments where PDZ15B/S911115 is deployed.
What is the maximum reverse leakage current for PDZ15B/S911115?
The maximum reverse leakage current (IR) for PDZ15B/S911115 is 0.05 μA at VR = 11.0 V and Tj = 25 °C. This ultra-low leakage supports energy-efficient operation in battery-powered systems and high-impedance circuits where even nanoamp-level currents could affect accuracy-confirming PDZ15B/S911115's suitability for precision biasing and always-on monitoring functions.
Is PDZ15B/S911115 compatible with automated SMT assembly processes?
Yes, PDZ15B/S911115 uses the JEDEC-standard SOD323 (SC-76) package and is fully compatible with industry-standard reflow and wave soldering processes. Figures 9 and 10 in the datasheet provide validated solder land patterns, and its marking bar (cathode indicator) ensures correct orientation during automated placement-making PDZ15B/S911115 suitable for high-yield, high-volume manufacturing where PDZ15B/S911115 integration must be repeatable and defect-free.
What is the differential resistance of PDZ15B/S911115 and why does it matter?
The differential resistance (rdif) of PDZ15B/S911115 is 80 Ω maximum at IZ = 5 mA. This parameter quantifies how much the Zener voltage changes per unit change in current-lower rdif means tighter regulation under varying load conditions. In practice, this allows PDZ15B/S911115 to maintain stable reference voltage in feedback loops and clamping circuits where current may fluctuate, directly improving system accuracy and noise immunity.
