Product details
Overview
PZU884LS-C11-Q from Nexperia is a ±5 % tolerance Zener voltage regulator diode with nominal 11 V breakdown voltage, ultra-small DFN1006BD-2 (SOD882BD) package, side-wettable flanks, and AEC-Q101 qualification for automotive use. It delivers 60 Ω differential resistance at 5 mA, 8 mV/K temperature coefficient, and 108 pF capacitance at 1 MHz - enabling stable voltage reference in space-constrained power rail monitoring circuits.
For engineers reviewing the PZU884LS-C11-Q datasheet, PZU884LS-C11-Q pinout, PZU884LS-C11-Q application, or PZU884LS-C11-Q equivalent, key selection criteria include its 11 V nominal Zener voltage with ±5 % tolerance, low 60 Ω dynamic impedance at IZ = 5 mA, AEC-Q101 qualification, side-wettable flank solderability, and suitability for automotive ECU power supply regulation and sensor biasing.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage across varying load and line conditions. Its design targets low-current regulation (IZ = 0.5–5 mA), with intentional leakage current optimization for fast switching and noise reduction per AN90031.
The device features hard breakdown knee characteristics and low forward voltage (VF ≤ 0.9 V at IF = 10 mA), supporting bidirectional protection and dual-role use in clamp-and-regulate topologies. Thermal resistance Rth(j-a) is 340 K/W on standard FR4 PCB, limiting continuous power dissipation to 365 mW at Tamb = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.44 V to 11.56 V at IZ = 5 mA - defines precise regulation window for 11 V nominal rail |
| Differential Resistance (rdif) | 60 Ω max at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Temperature Coefficient (SZ) | 5.4 mV/K to 9.0 mV/K - quantifies voltage drift over temperature for stability-critical references |
| Reverse Current (IR) | 0.1 μA max at VR = 8 V - enables low-power standby operation without excessive quiescent loss |
| Capacitance (Cd) | 108 pF at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering and transient response |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous thermal budget for board-level layout |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 μs - supports surge immunity in automotive load-dump scenarios |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), leadless ultra-small plastic package, 1.0 mm × 0.6 mm × 0.47 mm body, 0.65 mm pitch, side-wettable flanks for automated optical inspection (AOI) of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct orientation during placement |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction for Zener conduction |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C11,115 | ±5 % tolerance, SOT23 package (3.0 mm × 1.4 mm), higher Rth(j-a) (~450 K/W), no AEC-Q101 qualification | Not suitable for automotive under-hood use; limited thermal performance in dense layouts | Select only for cost-sensitive non-automotive consumer designs where board space and qualification are secondary |
| MMSZ5240B-TP | ±5 % tolerance, SOD-123 package (2.7 mm × 1.4 mm), 100 Ω rdif, no SWF, no AEC-Q101 | Higher dynamic impedance degrades regulation accuracy under dynamic loads; no AOI support | Prefer only for legacy designs reusing SOD-123 footprints where DFN1006BD-2 rework is impractical |
Compared with BZX84-C11,115 and MMSZ5240B-TP, PZU884LS-C11-Q offers superior thermal performance in ultra-compact form factor, AEC-Q101 compliance for automotive deployment, and side-wettable flanks for process traceability - making it the optimal choice for next-generation space- and reliability-constrained applications.

FAQ
What is the maximum continuous reverse power dissipation for PZU884LS-C11-Q at 85 °C ambient?
At Tamb = 85 °C, derated power dissipation is 245 mW, calculated using the 365 mW rating at 25 °C and thermal resistance of 340 K/W. This assumes standard FR4 PCB mounting with single-sided 70 μm copper and tin plating per datasheet condition [2]. Exceeding this limit risks thermal runaway and parametric shift.
Does PZU884LS-C11-Q support reflow soldering per JEDEC J-STD-020?
Yes - the DFN1006BD-2 package is qualified for standard lead-free reflow profiles (peak 260 °C, 20–40 s above 217 °C). Footprint dimensions (1.3 mm × 0.8 mm lands, 0.4 mm solder mask opening) match Nexperia's recommended reflow soldering layout in Figure 10, ensuring void-free joints with side-wettable flank visibility.
How does the temperature coefficient vary with operating current for this part?
At VZ = 11 V, SZ ranges from 5.4 mV/K (min) to 9.0 mV/K (max) across IZ = 0.5–5 mA. Per Figure 4, coefficient increases with current - e.g., ~6.5 mV/K at 1 mA and ~8.2 mV/K at 5 mA - enabling predictable drift modeling in closed-loop compensation designs.
Can PZU884LS-C11-Q be used as a bidirectional ESD clamp?
No - it is a unidirectional Zener diode optimized for reverse-bias regulation. Forward conduction (VF ≤ 0.9 V at 10 mA) lacks the low dynamic impedance and fast response required for effective ESD clamping. Use dedicated TVS diodes like PESD5V0S1BA for bidirectional transient suppression.
