Product details
Overview
PZU884LS-C33-Q from Nexperia is a ±5 % tolerance Zener voltage regulator diode with nominal 33 V breakdown voltage, ultra-low leakage current (≤0.05 μA at VR = 33 V), differential resistance of 250 Ω at IZ = 5 mA, and AEC-Q101 qualification for automotive power rail stabilization in engine control units and ADAS sensor modules.
For engineers reviewing the PZU884LS-C33-Q datasheet, PZU884LS-C33-Q pinout, PZU884LS-C33-Q application, or PZU884LS-C33-Q equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at low bias current, thermal resistance (340 K/W), side-wettable flank solderability, and automotive-grade reliability validation.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its hard breakdown knee and low leakage (<0.05 μA) enable precise regulation in low-power sensing circuits without compromising noise performance.
The device uses a planar silicon process optimized for tight voltage distribution across the E24 range (2.4 V–51 V) and features intentional leakage tuning in the C-series for improved switching transients and reduced high-frequency noise-validated per AN90031.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 31.0 V to 35.0 V at IZ = 5 mA - defines regulated output voltage window under standard test conditions |
| Differential Resistance (rdif) | 250 Ω max at IZ = 5 mA - determines output voltage stability against load current variation |
| Reverse Leakage (IR) | ≤0.05 μA at VR = 33 V - ensures minimal quiescent current draw in battery-backed systems |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous DC power handling in standard layout |
| Thermal Resistance (Rth(j-a)) | 340 K/W - defines junction-to-ambient temperature rise per watt, critical for thermal derating |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 μs square wave - supports transient overvoltage clamping in surge protection |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables use as polarity protection diode in dual-role designs |

FAQ
What is the maximum continuous reverse current the PZU884LS-C33-Q can sustain without exceeding its thermal limits?
At Tamb = 25 °C on a standard FR4 PCB, the device sustains up to 11.1 mA continuously (365 mW ÷ 33 V) before reaching its 150 °C junction limit. Derating is required above 25 °C ambient per the 340 K/W Rth(j-a) value-e.g., at 100 °C ambient, max continuous current drops to ~1.5 mA.
How does the "C" suffix in PZU884LS-C33-Q affect its electrical behavior versus the "B" variant?
The "C" suffix denotes the low-leakage, hard-knee Zener variant optimized for precision regulation: IR ≤0.05 μA at VR = 33 V and rdif = 250 Ω at 5 mA. In contrast, the "B" variant (e.g., PZU884LS-B33-Q) exhibits slightly higher leakage and softer knee for noise reduction in switching applications per AN90031.
Can PZU884LS-C33-Q be used in forward conduction mode, and what is its typical forward voltage?
Yes-it functions as a standard silicon diode in forward bias. At IF = 10 mA, VF is ≤0.9 V (pulse-tested), making it suitable for polarity protection or OR-ing functions in dual-supply systems where space constraints favor dual-role components.
Is the DFN1006BD-2 package compatible with standard reflow profiles, and what is the recommended solder land pattern?
Yes-the package is qualified for IPC/JEDEC J-STD-020D reflow. The recommended footprint (per Figure 10) uses 0.7 mm × 0.6 mm solder lands with 0.4 mm solder mask opening and 0.3 mm solder paste stencil aperture to ensure reliable side-wettable flank wetting and void-free joints.
