Product details
Overview
PZU884LS-C27-QYL from Nexperia is a Zener voltage regulator diode in the PZU884LS-Q series, designed for precision voltage reference and regulation in compact automotive and industrial power rails. It delivers a nominal 27 V Zener voltage with ±5 % tolerance, 150 Ω differential resistance at IZ = 5 mA, 21 mV/K temperature coefficient, and supports up to 365 mW steady-state dissipation in a DFN1006BD-2 (SOD882BD) package. Used in ECU voltage clamping and sensor biasing circuits.
For engineers reviewing the PZU884LS-C27-QYL datasheet, PZU884LS-C27-QYL pinout, PZU884LS-C27-QYL application, or PZU884LS-C27-QYL equivalent, key selection criteria include Zener voltage tolerance, low leakage current (<0.05 μA at VR = 21 V), side-wettable flanks for automated optical inspection, AEC-Q101 qualification, and thermal resistance of 340 K/W on FR4.
Technical Context
This Zener diode operates in reverse breakdown mode with hard knee characteristics optimized for stable reference generation under low-current conditions (IZ = 0.5–5 mA). Its differential resistance remains ≤150 Ω across the specified working current range, ensuring minimal output voltage variation during load transients.
The device features intentional low leakage current (≤0.05 μA at VR = 21 V) and a predictable temperature coefficient of +21 mV/K, enabling accurate compensation in temperature-sensitive analog circuits. It is qualified per AEC-Q101 and rated for junction temperatures up to 150 °C.
Key Specifications

| Zener Voltage VZ | 25.1 V to 28.9 V at IZ = 5 mA - defines precise clamping threshold for 27 V nominal rail protection |
| Differential Resistance rdif | 150 Ω max at IZ = 5 mA - ensures <15 mV output shift per 1 mA current change in regulation zone |
| Temperature Coefficient SZ | +21 mV/K - enables predictable drift compensation in automotive ambient ranges (−40 °C to +125 °C) |
| Reverse Current IR | ≤0.05 μA at VR = 21 V - minimizes standby power loss in battery-critical systems |
| Total Power Dissipation Ptot | 365 mW at Tamb = 25 °C on FR4 - supports continuous operation in space-constrained PCB layouts |
| Junction Temperature Tj | −55 °C to +150 °C - meets extended temperature requirements for engine bay and ADAS modules |

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The PZU884LS-C27-QYL has a nominal Zener voltage of 27 V with a guaranteed range of 25.1 V to 28.9 V at IZ = 5 mA. Its absolute maximum non-repetitive peak reverse voltage is defined by the 40 W surge rating at 100 μs pulse width-not a fixed DC voltage limit. Continuous reverse operation must remain within the specified VZ band under controlled current conditions.
Does this part support reflow soldering with standard lead-free profiles?
Yes. The DFN1006BD-2 package is qualified for lead-free reflow soldering per JEDEC J-STD-020. Recommended peak temperature is 260 °C, with time above 217 °C limited to 60–150 seconds. The side-wettable flanks ensure reliable solder joint formation and AOI compatibility on automated assembly lines.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
With a specified +21 mV/K temperature coefficient, the Zener voltage shifts approximately +1.05 V across a 50 K rise (e.g., −40 °C to +105 °C). This predictable linear drift allows system-level compensation in closed-loop designs and remains within ±3 % total variation over the full AEC-Q101 ambient range.
Is the cathode marking visible after reflow soldering?
Yes. The cathode is indicated by a laser-marked bar on the top surface of the DFN1006BD-2 package. This marking remains fully legible post-reflow and is compatible with automated optical inspection systems, supporting traceability and polarity verification in high-volume manufacturing.
