Product details

Overview

BZV90-C11,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, rated for 11 V nominal working voltage (10.4–11.6 V), 8–20 Ω differential resistance at 5 mA test current, ±5% tolerance, 1.5 W total power dissipation, and −2.0 to +7.4 mV/K temperature coefficient - used for precision DC voltage reference and overvoltage protection in industrial power supplies.

For engineers reviewing the BZV90-C11,115 datasheet, BZV90-C11,115 pinout, BZV90-C11,115 application, or BZV90-C11,115 equivalent, key selection criteria include Zener voltage accuracy at I_Ztest = 5 mA, thermal resistance (83.3 K/W), non-repetitive peak reverse power (40 W), and SOT223 thermal pad layout compatibility with FR4 PCB copper area ≥2 cm².

Technical Context

The BZV90-C11,115 operates as a two-terminal shunt regulator, maintaining stable reverse-biased breakdown voltage across its cathode-anode terminals under controlled current conditions. Its Zener mechanism delivers predictable regulation with low dynamic impedance (10 Ω typical) and moderate temperature drift (5.4–7.4 mV/K).

Designed for surface-mount operation on double-sided FR4 PCBs with 2 cm² copper area, it supports transient suppression via 40 W non-repetitive peak reverse power handling (100 μs square wave), while junction temperature remains ≤150 °C under steady-state 1.5 W dissipation.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage V_Z	10.4–11.6 V at I_Ztest = 5 mA - defines regulated output voltage range under standard test conditions
Differential Resistance r_dif	10–20 Ω at I_Ztest = 5 mA - determines load regulation sensitivity and output impedance
Temp. Coefficient S_Z	5.4–7.4 mV/K at I_Ztest = 5 mA - quantifies voltage drift per degree Celsius change in junction temperature
Total Power Dissipation P_tot	1500 mW at T_amb = 25 °C - sets maximum continuous DC power handling on specified PCB layout
Non-repetitive Peak Power P_ZSM	40 W for t_p = 100 μs - enables short-duration surge clamping without device failure
Reverse Current I_R	≤0.1 μA at V_R = 8.5 V - ensures minimal leakage below knee voltage in standby circuits
Junction Temperature T_j	−65 to +150 °C - defines operational and storage thermal envelope for reliability assurance

Pinout & Package

SOT223 plastic surface-mounted package with exposed collector pad for enhanced thermal conduction; 4-lead configuration (pins 1 and 3 anode, pins 2 and 4 cathode) optimized for high-power dissipation on FR4 PCBs with ≥2 cm² copper area.

Pin/Terminal	Circuit Role	Design Meaning
1	Anode	Main anode connection; electrically tied to pin 3; used for forward bias or current return path
2	Cathode	Main cathode connection; electrically tied to pin 4; connects to regulated voltage node
3	Anode	Secondary anode terminal; redundant connection to pin 1 for improved current sharing and thermal spreading
4	Cathode	Secondary cathode terminal; redundant connection to pin 2 for lower parasitic inductance in transient clamping

Key Features

Feature	Design Value
E24 ±5% voltage tolerance	Ensures interchangeability within standardized Zener voltage bins without recalibration
1.5 W continuous power rating	Supports stable regulation in mid-power supply rails (e.g., 12 V systems) without heatsinking
40 W non-repetitive peak power	Enables robust ESD and surge immunity in industrial I/O protection circuits
Low 10 Ω typical differential resistance	Minimizes output voltage variation under ±10 mA load current shifts
SOT223 thermal pad design	Reduces R_{th j-a} to 83.3 K/W, enabling >1 W dissipation on standard FR4 layouts

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C11	Same 11 V nominal rating but SOT23 package; 350 mW P_tot; higher r_dif (30 Ω typ.)	Limited to low-power signal-level regulation; unsuitable for >100 mA current sinks	Select when board space is constrained and power <0.35 W
PZM11NB	11 V, SOT323 package; 400 mW P_tot; tighter ±2% tolerance; 15 Ω r_dif	Better accuracy and lower noise, but lower surge rating (10 W P_ZSM)	Select for high-precision analog references where surge immunity is secondary

Compared with BZX84-C11 and PZM11NB, the BZV90-C11,115 uniquely balances high power (1.5 W), robust surge handling (40 W), and SOT223 thermal performance - making it optimal for industrial and automotive power-rail regulation where both precision and ruggedness are required.

FAQ

What is the maximum continuous reverse current the BZV90-C11,115 can sustain at 25 °C ambient?

The BZV90-C11,115 sustains up to 136 mA continuous reverse current at 25 °C ambient when mounted on FR4 with 2 cm² copper area, calculated from P_tot = 1500 mW and V_Z ≈ 11 V (I_Zmax = P_tot/V_Z). Derating applies above 25 °C per R_{th j-a} = 83.3 K/W.

Does the BZV90-C11,115 require external series resistance in standard regulation circuits?

Yes - a series current-limiting resistor is mandatory to set I_Z within 1–10 mA for stable regulation. For V_IN = 15 V and target I_Z = 5 mA, R_S = (15 V − 11 V)/5 mA = 800 Ω, ensuring operation within specified differential resistance and temperature coefficient ranges.

How does the temperature coefficient of the BZV90-C11,115 affect regulation accuracy over −40 to +125 °C?

With S_Z = +5.4 to +7.4 mV/K, the BZV90-C11,115 exhibits positive drift: voltage increases ~0.8–1.1 V across 150 K span. At 125 °C, V_Z rises to ~11.8–12.1 V, requiring system-level compensation if sub-1% accuracy is needed across full temperature range.

Can the BZV90-C11,115 be used in parallel for higher current handling?

No - Zener diodes exhibit manufacturing spread in V_Z and r_dif, causing current hogging. Parallel operation without individual ballast resistors risks thermal runaway. For >136 mA, use a single higher-rated device or active regulation instead.
