Product details
Overview
BZV90-C5V1,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and stabilization in power supply rails. It delivers a nominal working voltage of 5.1 V ±5%, with differential resistance of 40–60 Ω at 5 mA test current, 1.5 W total power dissipation, and operates up to 150 °C junction temperature - used in industrial power management and analog sensor biasing circuits.
For engineers reviewing the BZV90-C5V1,115 datasheet, BZV90-C5V1,115 pinout, BZV90-C5V1,115 application, or BZV90-C5V1,115 equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (83.3 K/W), non-repetitive peak reverse power (40 W), and SOT223 thermal pad layout for PCB heat sinking.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified test current range (IZtest = 5 mA). Its temperature coefficient is −2.7 to −0.8 mV/K, enabling stable reference performance over −65 °C to +150 °C ambient.
The device uses silicon planar epitaxial construction and features low dynamic impedance (rdif ≤ 60 Ω) and low capacitance (Cd ≤ 300 pF at 1 MHz, VR = 0 V), supporting fast transient response in feedback loops and noise-sensitive analog subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.8–5.4 V at 5 mA - defines regulated output rail accuracy under nominal bias |
| Differential Resistance (rdif) | 40–60 Ω at 5 mA - determines load regulation error and ripple rejection capability |
| Temp. Coefficient (SZ) | −2.7 to −0.8 mV/K - quantifies voltage drift per degree Celsius over operating range |
| Total Power Dissipation (Ptot) | 1500 mW at Tamb = 25 °C - sets maximum continuous DC power handling on 2 cm² FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 μs - supports surge immunity in input protection and clamp circuits |
| Junction Temperature (Tj) | −65 to +150 °C - enables deployment in extended-temperature industrial environments |
| Reverse Current (IR) | ≤2 μA at VR = 2 V - ensures low leakage in high-impedance reference nodes |

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-C5V1 | Same 5.1 V rating but SOT23 package; lower Ptot (300 mW); higher rdif (60 Ω min) | Limited to low-power signal-level regulation; unsuitable for >100 mA load currents | Select when board space is constrained and thermal budget is low |
| MMBZ5222BS | 5.1 V ±5%; SOT323 package; Ptot = 200 mW; Cd = 200 pF | Optimized for high-frequency clamping; not rated for continuous 1.5 W dissipation | Prefer for RF/EMI suppression where size and capacitance dominate over power handling |
Compared with BZX84-C5V1 and MMBZ5222BS, the BZV90-C5V1,115 uniquely supports 1.5 W continuous regulation and 40 W transient clamping in a thermally robust SOT223 package - making it the only option among the three for industrial-grade power rail stabilization.

FAQ
What is the maximum continuous reverse current the BZV90-C5V1,115 can sustain at 25 °C?
The device does not specify a maximum continuous reverse current; instead, it is rated by Zener test current (IZtest = 5 mA) and total power dissipation (1500 mW). At 5.1 V, this corresponds to ~294 mA maximum continuous Zener current before exceeding Ptot - assuming ideal thermal conditions (2 cm² copper, Tamb = 25 °C).
Does the SOT223 package require soldering the thermal pad to PCB ground?
Yes - the exposed pad (pins 2 and 4) must be soldered to a minimum 2 cm² copper pour for thermal performance. The datasheet specifies Rth(j-a) = 83.3 K/W only when mounted on double-sided FR4 with that copper area; omitting the pad increases junction temperature by >40 °C at full power.
Can BZV90-C5V1,115 replace BZX84-C5V1 in existing designs?
No - while both regulate at 5.1 V, BZV90-C5V1,115 has different pinout (4-pin SOT223 vs. 3-pin SOT23), higher power rating, and distinct thermal requirements. Direct substitution requires PCB layout revision, thermal analysis, and validation of surge handling in the target application.
What is the typical Zener impedance at 10 mA, and how does it affect regulation accuracy?
At 10 mA, rdif is typically 45 Ω (interpolated from 5 mA and 20 mA data points in the datasheet). This impedance causes ~0.45 V output change per 10 mA load step - critical for designing feedback compensation in linear regulators and determining minimum cathode current for stable regulation.
