Product details
Overview
PZU884LS-C7V5-Q from Nexperia is a leadless surface-mount Zener voltage regulator diode in the SOD882BD (DFN1006BD-2) package, rated for 7.5 V nominal breakdown voltage with ±5 % tolerance, 60 Ω typical differential resistance at IZ = 5 mA, and qualified to AEC-Q101 for automotive power rail stabilization.
For engineers reviewing the PZU884LS-C7V5-Q datasheet, PZU884LS-C7V5-Q pinout, PZU884LS-C7V5-Q application, or PZU884LS-C7V5-Q equivalent, this device serves as a precision low-current voltage reference and overvoltage clamp in space-constrained automotive ECUs, sensor signal conditioning circuits, and battery management monitoring paths where side-wettable flanks support automated optical inspection (AOI) and solder joint reliability.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with a hard knee characteristic optimized for stable regulation at low currents (IZ = 0.5 mA to 5 mA), featuring 4 Ω to 60 Ω differential resistance depending on voltage grade and test current. Its temperature coefficient of +2.5 mV/K at 7.5 V enables predictable drift compensation in ambient ranges from −55 °C to +150 °C.
The device uses silicon planar technology with side-wettable flanks for reliable reflow soldering on FR4 PCBs, supports non-repetitive surge power up to 40 W (tp = 100 μs), and maintains ≤ 0.5 μA reverse leakage at VR = 5.7 V - critical for low-power always-on subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 7.5 V ±5 % - defines regulated output voltage under 5 mA test current; actual range 7.06 V to 7.84 V. |
| Differential Resistance | 60 Ω max at IZ = 5 mA - ensures minimal output voltage shift under load variation in feedback networks. |
| Reverse Leakage Current | ≤ 0.5 μA at VR = 5.7 V - preserves ultra-low quiescent current in battery-backed circuits. |
| Forward Voltage | ≤ 0.9 V at IF = 10 mA - enables use as polarity protection or clamping diode in dual-role designs. |
| Power Dissipation | 365 mW at Tamb = 25 °C on standard FR4 - sets thermal design limit for continuous DC regulation without heatsinking. |
| Junction Temperature | −55 °C to +150 °C - supports operation in engine bay and transmission control modules. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HTOL, TC, and ESD testing per AEC stress requirements. |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), leadless 2-terminal surface-mount plastic package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for AOI-compatible solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated voltage node; reverse-bias anode connection point for Zener operation. |
| 2 | Anode (A) | Ground or lower-potential reference; forms current path during breakdown conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on both package edges, improving manufacturing yield in high-volume automotive assembly. |
| Hard breakdown knee | Sharp, well-defined Zener transition at 7.5 V minimizes regulation hysteresis in feedback loops and improves accuracy in analog sensing interfaces. |
| Low dynamic impedance | 60 Ω typical at 5 mA ensures <15 mV output deviation across ±1 mA load changes - suitable for precision biasing of op-amps and ADC references. |
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensors requiring extended temperature and lifetime reliability. |
| Ultra-small footprint | 0.6 mm pitch and 0.6 mm width allow placement in dense PCB layouts near microcontrollers or power ICs without compromising routing space. |
Applications
| Engine Control Unit (ECU) Power Monitoring | Automotive Cabin Sensor Biasing |
|---|---|
Use Scenario: Monitoring 12 V battery rail voltage in real time to detect undervoltage/overvoltage faults before MCU reset. IC Role / Device Role / Timing Role: Zener clamp referenced to MCU ADC input, providing ratiometric scaling of rail voltage with known 7.5 V reference point. Use Value: Enables accurate ±2 % rail measurement using internal 10-bit ADC without external precision reference IC, reducing BOM cost and board area. |
Use Scenario: Providing stable bias voltage to MEMS pressure or humidity sensors in HVAC control modules. IC Role / Device Role / Timing Role: Low-leakage Zener reference supplying excitation voltage to sensor bridge, minimizing self-heating and offset drift. Use Value: Maintains sensor linearity within ±0.5 % full-scale error over −40 °C to +105 °C due to predictable +2.5 mV/K TC and sub-μA leakage. |
| Infotainment System ESD Protection | Electric Power Steering (EPS) Feedback Clamping |
Use Scenario: Protecting USB data lines and audio codec inputs from transient surges in vehicle infotainment head units. IC Role / Device Role / Timing Role: Fast-response Zener clamp shunting ESD pulses (>8 kV contact) to ground while preserving signal integrity below 7.5 V. Use Value: Achieves IEC 61000-4-2 Level 4 compliance with <1 ns response and no latch-up risk, unlike TVS diodes with higher capacitance. |
Use Scenario: Clamping position sensor feedback signals in EPS motor control to prevent ADC saturation during fault conditions. IC Role / Device Role / Timing Role: Bidirectional voltage limiter placed between resolver-to-digital converter output and MCU input, limiting swing to ±7.5 V. Use Value: Prevents erroneous torque calculation by restricting analog feedback to safe range without adding propagation delay or signal distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V5,115 | Same 7.5 V ±5 % rating but in SOT23 package; 90 Ω rdif at 5 mA; no AEC-Q101 qualification. | Limited to industrial/commercial use; lacks side-wettable flanks and automotive reliability validation. | Select when cost sensitivity outweighs AOI requirement and automotive qualification is not mandated. |
| MMSZ5236B-TP | 7.5 V ±5 % in SOD-123; 30 Ω rdif at 20 mA; 500 mW Ptot; no AEC-Q101. | Higher power handling but larger footprint; unsuitable for ultra-dense layouts or automotive production traceability. | Prefer for non-automotive applications needing higher surge margin and less stringent size constraints. |
Compared with BZX84-C7V5,115 and MMSZ5236B-TP, the PZU884LS-C7V5-Q delivers superior manufacturability via side-wettable flanks, tighter low-current regulation (60 Ω vs. ≥90 Ω), and guaranteed automotive qualification - making it the only choice for production-grade automotive PCBs requiring zero-defect solder joint inspection and long-term reliability.

FAQ
What is the maximum continuous reverse power dissipation for PZU884LS-C7V5-Q at 85 °C ambient?
At 85 °C ambient, derated power dissipation is 245 mW, calculated using the 340 K/W junction-to-ambient thermal resistance and 150 °C max junction temperature: Ptot = (Tjmax − Tamb) / Rth(j-a) = (150 − 85) / 340 ≈ 0.191 W. The datasheet specifies 365 mW at 25 °C, confirming linear derating applies.
Does PZU884LS-C7V5-Q support reflow soldering with lead-free SAC305 paste?
Yes - the DFN1006BD-2 package is qualified for standard lead-free reflow profiles (peak 260 °C, 30 s dwell). The side-wettable flank geometry and tin-plated terminations ensure robust wetting and void-free solder joints when using IPC-J-STD-020-compliant thermal profiles.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a +2.5 mV/K coefficient, the Zener voltage shifts +212.5 mV across 85 K ΔT, resulting in ±1.4 % deviation from nominal 7.5 V. This is fully characterized in Table 8 and acceptable for non-precision biasing where absolute accuracy is secondary to stability and repeatability.
Can PZU884LS-C7V5-Q be used in series to achieve higher regulation voltages?
No - series connection is not recommended due to mismatched temperature coefficients and dynamic impedances between devices, causing uneven voltage division and thermal runaway risk. For >7.5 V regulation, select a single higher-voltage Zener from the same PZU884LS-Q series (e.g., PZU884LS-C10-Q).
