Product details

Overview

PZU84-C15R from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, rated for 15 V nominal breakdown voltage at I_Z = 5 mA, with differential resistance of 80 Ω (max), reverse leakage ≤ 0.05 μA at V_R = 11 V, and total power dissipation of 250 mW. It serves as a precision reference or shunt regulator in low-power analog supply rails and sensor biasing circuits.

For engineers reviewing the PZU84-C15R datasheet, PZU84-C15R pinout, PZU84-C15R application, or PZU84-C15R equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at regulation current, thermal resistance (R_th(j-a) = 500 K/W), junction temperature limit (150 °C), and SOT23 footprint compatibility with automated assembly.

Technical Context

This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage across its cathode–anode terminals under varying load currents. Its hard breakdown knee and low leakage (≤0.05 μA at 11 V) support accurate voltage referencing in low-current (<5 mA) applications.

The device belongs to the PZU84-C subseries optimized for low-noise, high-stability regulation-distinct from the B-series' intentional leakage increase for switching noise reduction. Its temperature coefficient is +9.2 mV/K (typical at I_Z = 5 mA), enabling predictable drift compensation in compensated references.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage V_Z	13.84 V to 15.52 V at I_Z = 5 mA - defines regulation band for precision 15 V reference
Differential Resistance r_dif	80 Ω max at I_Z = 5 mA - determines output impedance and load regulation error
Reverse Leakage I_R	≤ 0.05 μA at V_R = 11 V - ensures minimal quiescent current in standby bias networks
Total Power Dissipation P_tot	250 mW at T_amb = 25 °C on FR4 PCB - sets maximum continuous power handling in standard layout
Junction Temperature T_j	−55 °C to +150 °C - enables operation in extended industrial environments
Thermal Resistance R_th(j-a)	500 K/W in free air - informs derating curve for ambient temperature rise
Forward Voltage V_F	≤ 0.9 V at I_F = 10 mA - relevant for polarity-check or ESD protection use cases

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	Same 15 V nominal, ±5 % tolerance; higher r_dif (100 Ω max); 350 mW P_tot	Less precise regulation but higher surge capability; suited for cost-sensitive, non-critical rails	Select when ±5 % tolerance is acceptable and board space allows larger thermal pad
MMSZ5245B	15 V nominal, ±5 %; SOD-123 package; r_dif = 17 Ω typical; 500 mW P_tot	Lower impedance but larger footprint; higher power rating supports higher current loads	Choose for improved regulation accuracy at >10 mA loads where SOD-123 mounting is feasible

Compared with BZX84-C15 and MMSZ5245B, PZU84-C15R delivers tighter voltage tolerance (±2 % vs. ±5 %) and lower leakage in the same SOT23 footprint-making it optimal for precision low-current references where stability outweighs surge margin or raw power handling.

FAQ

What is the maximum continuous Zener current for PZU84-C15R at 70 °C ambient?

At T_amb = 70 °C, derating applies: P_tot = 250 mW × (1 − (70 − 25)/125) = 140 mW. With V_Z ≈ 15 V, maximum continuous I_Z = 140 mW / 15 V ≈ 9.3 mA. This assumes standard FR4 PCB mounting per datasheet condition [2].

Does PZU84-C15R support bidirectional ESD protection?

No. PZU84-C15R is a unidirectional Zener diode optimized for reverse-bias regulation only. Its forward voltage is 0.9 V max at 10 mA, but it lacks specified ESD parameters (e.g., IEC 61000-4-2 rating) and is not characterized for transient suppression in either direction.

How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?

With SZ = +9.2 mV/K (typical), V_Z shifts +0.92 V from −40 °C to +25 °C and +1.38 V from +25 °C to +125 °C. Total drift is ~2.3 V across the full range, so system-level compensation or calibration is required for sub-1 % accuracy over temperature.

Can Pin 2 (n.c.) be used as a thermal pad or ground connection?

No. Pin 2 is internally not connected per Table 2 and Figure 9. It provides no electrical or thermal path. Using it as a thermal pad would violate the qualified SOT23 thermal model (R_th(j-sp) = 330 K/W referenced to cathode tab only) and risk solder joint reliability issues.
