Product details
Overview
BZX84J-C4V7,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOD323F (SC-90) package, rated for 4.4 V to 5.0 V nominal Zener voltage at 5 mA test current, 550 mW total power dissipation, and AEC-Q101 qualified for automotive use. It provides low differential resistance (80 Ω max) and stable reverse breakdown for precision voltage reference and overvoltage protection in compact DC power rails.
For engineers reviewing the BZX84J-C4V7,115 datasheet, BZX84J-C4V7,115 pinout, BZX84J-C4V7,115 application, or BZX84J-C4V7,115 equivalent, key selection criteria include Zener voltage tolerance, pulse power handling (≤40 W), thermal resistance (230 K/W), cathode-anode polarity marking, and AEC-Q101 qualification status for harsh-environment deployment.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with a specified Zener voltage of 4.4–5.0 V at IZ = 5 mA and exhibits a temperature coefficient of –3.5 to 0.2 mV/K. Its low differential resistance (≤80 Ω) ensures minimal voltage variation under load current changes.
The device supports non-repetitive surge conditions up to 40 W (100 µs square wave, Tj = 25 °C prior to surge) and maintains stable regulation across –55 °C to +150 °C ambient range. Junction-to-ambient thermal resistance is 230 K/W on FR4 PCB with 1 cm² cathode pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.4 V to 5.0 V at IZ = 5 mA - defines regulated output voltage under nominal bias |
| Tolerance | ±5 % - sets absolute accuracy band for voltage reference applications |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - limits continuous DC power handling on standard FR4 layout |
| Differential Resistance (rdiff) | ≤80 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Non-repetitive Peak Power (PZSM) | 40 W (100 µs, square wave) - enables transient overvoltage clamping without failure |
| Junction Temperature (Tj) | 150 °C maximum - defines upper thermal limit for reliable long-term operation |
| AEC-Q101 Qualified | Yes - confirms suitability for automotive electronics per stress-test qualification standard |
Pinout & Package
The BZX84J-C4V7,115 is housed in a SOD323F (SC-90) surface-mount plastic package measuring 2.7 mm × 1.6 mm × 0.9 mm with gull-wing leads. The cathode is marked by a bar on the package body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; connected to regulated output node; marking bar identifies this pin |
| 2 | Anode (A) | Positive terminal; tied to ground or lower-potential rail in shunt regulation configuration |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C4V7,115 | Same Zener voltage and tolerance, but not AEC-Q101 qualified; PZSM = 40 W only for ≥7.5 V types (lower surge rating at 4.7 V) | Limited to commercial-grade applications; unsuitable for automotive or extended-temperature industrial use | Select only if AEC-Q101 compliance is unnecessary and cost is primary constraint |
| MMSZ4704T1G | 4.7 V ±5 %, SOD-123 package, Ptot = 500 mW, rdiff = 90 Ω, no AEC-Q101 qualification | Higher thermal resistance (~300 K/W); less robust surge performance; incompatible footprint | Choose only for legacy SOD-123 board reuse where re-layout is impractical |

FAQ
What is the maximum continuous forward current for BZX84J-C4V7,115?
The absolute maximum forward current is 250 mA per limiting values table. However, forward conduction is not its intended operating mode; design must ensure reverse-bias operation with IZ ≤ 5 mA for regulation stability and thermal safety.
Does BZX84J-C4V7,115 support bidirectional transient suppression?
No - it is a unidirectional Zener diode configured for reverse-bias regulation only. Forward conduction occurs at ~1.1 V (IF = 100 mA), but it lacks symmetrical clamping characteristics required for bidirectional TVS applications.
How does the ±5 % tolerance affect regulation accuracy in a 5 V rail monitor?
At 5 mA test current, the actual Zener voltage falls between 4.4 V and 5.0 V. For a 5 V rail supervisor, this means the trip threshold may vary by ±0.3 V, requiring downstream comparator hysteresis or calibration to maintain functional safety margins.
Can BZX84J-C4V7,115 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. Use a single device within its 550 mW derated limit or select a higher-power alternative.
