Product details

Overview

PZU84-C3V0-Q from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, delivering 3.0 V nominal regulation at 5 mA with 95 Ω differential resistance and ≤1.0 μA reverse leakage at VR = 1.0 V, used for precision biasing and voltage reference in automotive ECUs and sensor signal conditioning circuits.

For engineers reviewing the PZU84-C3V0-Q datasheet, PZU84-C3V0-Q pinout, PZU84-C3V0-Q application, or PZU84-C3V0-Q equivalent, this page provides verified Zener parameters including V_Z tolerance, r_dif, temperature coefficient, thermal resistance, and AEC-Q101 qualification status - critical for automotive-grade voltage stabilization design.

Technical Context

This device operates as a two-terminal shunt regulator with hard breakdown knee and low dynamic impedance (95 Ω at I_Z = 5 mA), optimized for stable reference generation under low-current conditions. Its −3.5 to 0.0 mV/K temperature coefficient ensures minimal drift across −55 °C to +150 °C ambient range.

Designed per AEC-Q101, it supports automotive applications requiring robust transient immunity: non-repetitive peak reverse power dissipation reaches 40 W (t_p = 100 μs), while junction-to-ambient thermal resistance is 500 K/W on standard FR4 PCB.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage V_Z	2.80 V to 3.20 V at I_Z = 5 mA - defines tight 3.0 V regulation window for precision analog references
Differential Resistance r_dif	95 Ω max at I_Z = 5 mA - ensures minimal output voltage variation under load current changes
Reverse Leakage I_R	≤1.0 μA at V_R = 1.0 V - enables low-power standby operation without significant quiescent loss
Temperature Coefficient S_Z	−3.5 to 0.0 mV/K - guarantees predictable, bounded V_Z drift over full automotive temperature range
Total Power Dissipation P_tot	250 mW at T_amb = 25 °C - sets maximum continuous DC power handling on standard FR4 layout
Junction Temperature T_j	−55 °C to +150 °C - supports operation in engine bay and transmission control environments
AEC-Q101 Qualified	Yes - validated for automotive discrete semiconductor stress testing including HTGB, HTRB, and ESD

Pinout & Package

SOT23 plastic surface-mounted package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch, 3-terminal configuration with cathode tab solder point.

Pin/Terminal	Circuit Role	Design Meaning
1	Anode (A)	DC input terminal; connects to lower-potential node in shunt regulation topology
2	Not Connected (n.c.)	Internally unconnected; must remain floating - no PCB trace or thermal pad connection
3	Cathode (K)	Regulated output node; ties to reference voltage rail and provides thermal path via solder point

Key Features

Feature	Design Value
±2 % V_Z tolerance	Enables direct replacement in high-accuracy 3.0 V reference designs without calibration adjustment
Hard breakdown knee	Ensures sharp, predictable conduction onset at rated V_Z, reducing regulation uncertainty near threshold
Low r_dif at low I_Z	Maintains regulation stability even at 0.5 mA operating current - ideal for ultra-low-power sensor interfaces
AEC-Q101 qualification	Validates reliability for 15-year automotive service life under thermal cycling, humidity, and vibration stress
FR4-compatible thermal design	500 K/W R_th(j-a) allows safe 250 mW operation using standard single-sided copper footprint

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener voltage regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C3V0	±5 % V_Z tolerance; 100 Ω r_dif; no AEC-Q101 qualification	Acceptable for consumer-grade power rails but not automotive safety-critical functions	Select only for cost-sensitive non-automotive designs where ±5 % regulation is sufficient
MMSZ5226ET1G	±5 % V_Z; 17 Ω r_dif at 20 mA; higher I_Z test current shifts operating point	Better low-impedance performance at higher currents, but leakage rises to 5 μA at 1 V	Prefer for industrial power supplies needing tighter regulation at >10 mA, not for low-I_Z sensor bias

Compared with BZX84-C3V0 and MMSZ5226ET1G, PZU84-C3V0-Q delivers superior accuracy (±2 %), lower leakage (≤1.0 μA), and automotive qualification - making it the sole choice for AEC-compliant 3.0 V reference designs requiring long-term stability at sub-mA operating currents.

FAQ

What is the maximum continuous forward current for PZU84-C3V0-Q?

The absolute maximum forward current is 200 mA per limiting values table. However, forward conduction is not its intended operating mode; the device is designed for reverse-biased Zener regulation. Forward voltage is specified at 10 mA (≤0.9 V), and sustained forward bias above 100 mA risks thermal runaway due to lack of thermal derating data in forward direction.

Does PZU84-C3V0-Q support wave soldering?

Yes - Nexperia provides dedicated wave soldering footprint dimensions (Figure 11) specifying 1.4 mm × 2.2 mm solder lands with 2.6 mm spacing. The SOT23 package is qualified for both reflow and wave processes, but wave soldering requires strict control of preheat ramp rate (<2 °C/s) and immersion time (<3 s) to avoid delamination per AN10351 guidelines.

How does the "C" suffix in PZU84-C3V0-Q differ from "B" variants?

The "C" suffix denotes the ±2 % tolerance series with very low dynamic impedance and low leakage, optimized for precision reference use. In contrast, "B" variants (e.g., PZU84-B3V0-Q) offer approximately ±5 % tolerance and feature intentionally higher leakage for improved switching speed and noise reduction - making "C" the correct choice for stable voltage reference, not fast transient suppression.

Can PZU84-C3V0-Q replace older PZU3.0 series diodes?

No - PZU84-C3V0-Q is not a drop-in replacement for legacy PZU3.0 parts. It uses updated process technology with tighter tolerances (±2 % vs. ±5 %), lower r_dif (95 Ω vs. 120 Ω), and revised thermal characteristics (R_th(j-a) = 500 K/W vs. 600 K/W). Board layout and thermal design must be revalidated, especially for high-temperature automotive deployments.
