Product details
Overview
PZU884LS-B14-QYL from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 14 V breakdown voltage, ±2 % tolerance, 80 Ω differential resistance at IZ = 5 mA, and AEC-Q101 qualification for automotive power rail stabilization.
For engineers reviewing the PZU884LS-B14-QYL datasheet, PZU884LS-B14-QYL pinout, PZU884LS-B14-QYL application, or PZU884LS-B14-QYL equivalent, this device supports low-leakage, hard-knee regulation in space-constrained automotive ECUs, sensor biasing, and precision reference circuits where side-wettable flanks enable optical solder-joint inspection.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its design targets low dynamic impedance (80 Ω typ. at 5 mA) and tight voltage tolerance (±2 %), enabling accurate clamping in 12 V automotive systems.
The device features intentional low leakage current (<0.1 μA at VR = 11 V) and a hard breakdown knee-characteristics confirmed for the B-series variant-making it suitable for low-power reference and overvoltage protection where minimal quiescent current and sharp regulation onset are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.70 V to 14.30 V at IZ = 5 mA - defines precise clamping threshold for 12 V system rails |
| Tolerance | ±2 % - ensures predictable regulation without post-production trimming |
| Differential Resistance (rdif) | 80 Ω max at IZ = 5 mA - maintains voltage stability against load current variations |
| Reverse Current (IR) | <0.1 μA at VR = 11 V - minimizes standby power loss in always-on automotive modules |
| Total Power Dissipation (Ptot) | 365 mW on FR4 PCB - supports continuous operation in compact ECU layouts without forced cooling |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables deployment in engine bay and transmission control units |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15 | ±5 % tolerance, 15 V nominal, SOT23 package (larger footprint, no side-wettable flanks) | Lacks AEC-Q101 qualification and automotive thermal robustness; higher rdif (150 Ω) | Acceptable for cost-sensitive industrial prototypes but not for production automotive designs requiring optical solder inspection. |
| MMSZ5241B | ±5 % tolerance, 14 V nominal, SOD-123 package (1.8 mm × 1.4 mm), 100 Ω rdif | No AEC-Q101 qualification; higher thermal resistance (Rth(j-a) = 500 K/W vs. 340 K/W) | Suitable for consumer-grade power management where board space and automotive compliance are not constraints. |
Compared with PZU884LS-B14-QYL, both alternatives offer similar nominal voltage but lack its combination of ±2 % tolerance, side-wettable flanks, AEC-Q101 validation, and 80 Ω dynamic impedance-key for high-reliability automotive voltage clamping where space, thermal performance, and process traceability are critical.

FAQ
What is the maximum reverse working voltage for PZU884LS-B14-QYL before breakdown?
The device exhibits a nominal Zener voltage of 14 V with a guaranteed range of 13.70 V to 14.30 V at 5 mA test current. Its specified reverse working voltage (VR) is 11 V-above which significant leakage begins, and full breakdown occurs at the VZ threshold. Operation above VZ must remain within the 365 mW steady-state and 40 W pulsed power limits to avoid thermal failure.
How does the side-wettable flank feature impact assembly yield?
Side-wettable flanks on the DFN1006BD-2 package allow automated optical inspection (AOI) of solder joint fillet formation along the lateral edges-eliminating reliance on X-ray for hidden-joint verification. This directly improves first-pass yield in high-volume automotive PCB assembly lines and reduces field return rates linked to insufficient solder wetting.
Is PZU884LS-B14-QYL suitable for bidirectional transient voltage suppression?
No. It is a unidirectional Zener diode optimized for reverse-bias regulation only. Its forward voltage is 0.9 V at 10 mA, but it lacks symmetrical clamping capability or specified surge ratings in forward conduction. For bidirectional TVS applications, dedicated devices such as PESDxLVSx series or automotive-grade TVS diodes should be used instead.
What is the temperature coefficient behavior of this Zener diode?
At 14 V nominal, the PZU884LS-B14-QYL exhibits a temperature coefficient (SZ) of approximately −2.0 mV/K, meaning its Zener voltage decreases by ~2 mV per degree Celsius rise in junction temperature. This negative coefficient is typical for mid-voltage Zeners and must be accounted for in precision reference designs operating across wide ambient ranges.
