Nexperia USA Inc. PZU10DB2,115

Overview

PZU10DB2,115 from Nexperia is a dual isolated general-purpose Zener diode in SOT353 (SC-88A) package, designed for precision voltage regulation and overvoltage protection in compact surface-mounted circuits. It features a nominal Zener voltage of 10 V (9.77–10.21 V), ±2 % tolerance (B2 series), 250 mW total power dissipation, 40 W non-repetitive peak reverse power capability, and AEC-Q101 qualification for automotive use.

For engineers reviewing the PZU10DB2,115 datasheet, PZU10DB2,115 pinout, PZU10DB2,115 application, or PZU10DB2,115 equivalent, this device serves as a space-constrained, halogen-free dual-Zener solution for rail stabilization, ESD clamping, and reference voltage generation in automotive body control modules, industrial sensor interfaces, and portable power management systems.

Technical Context

The PZU10DB2,115 integrates two electrically isolated Zener diodes in a single 5-pin SOT353 package, with independent anode–cathode pairs on pins 1–5 and pin 3–4 respectively. Its differential resistance is 60 Ω at I_Z = 5 mA, and temperature coefficient is +7 mV/K - enabling stable regulation across −55 °C to +150 °C ambient range.

It supports non-repetitive surge handling up to 40 W (t_p = 100 µs, square wave), with reverse current limited to 0.1 µA at V_R = 8 V and junction-to-ambient thermal resistance of 500 K/W on standard FR4 PCB - confirming suitability for transient-suppression roles in low-power analog signal chains.

FAQ

What is the maximum continuous reverse current the PZU10DB2,115 can sustain at 10 V?

The device is rated for a maximum continuous reverse current of 200 mA per diode (IF = 200 mA), but sustained operation at that level exceeds its 250 mW total power limit. At 10 V, the practical continuous Zener current is capped at 25 mA to stay within thermal limits on standard FR4 PCBs.

Can Pin 2 be used as a heatsink or ground connection?

No - Pin 2 is internally unconnected and must remain floating. Using it as a heatsink or ground violates the SOT353 mechanical design and risks shorting adjacent pins during reflow. Thermal management relies solely on pins 4 and 5, which connect to cathodes and serve as primary thermal paths.

How does the +7 mV/K temperature coefficient affect regulation stability?

The positive temperature coefficient means V_Z increases by ~7 mV per °C rise in junction temperature. Over a 125 °C operating range (−55 °C to +70 °C), this introduces up to ±0.875 V drift - mitigated in practice by low power dissipation (<25 mW typical) limiting self-heating to <15 °C rise.

Is the PZU10DB2,115 compatible with lead-free reflow profiles?

Yes - the SOT353 package is qualified for standard IPC/JEDEC J-STD-020D lead-free reflow, with peak temperatures up to 260 °C. The dark-green halogen-free variant (PZU10DB2/DG) meets JEDEC MSL3 requirements and supports 12-month floor life at ≤30 °C/60 % RH.
