Product details
Overview
BZX84J-B13,115 from Nexperia is a 13 V ±2 % Zener voltage regulator diode in SOD323F (SC-90) surface-mount package, designed for precision voltage reference and overvoltage protection in low-power analog and digital circuits. It delivers 13.0 V nominal Zener voltage at 5 mA test current, 103 Ω differential resistance, and supports non-repetitive peak reverse power dissipation up to 40 W with 100 µs pulse width. Used in automotive sensor signal conditioning and microcontroller reset circuitry.
For engineers reviewing the BZX84J-B13,115 datasheet, BZX84J-B13,115 pinout, BZX84J-B13,115 application, or BZX84J-B13,115 equivalent, this page provides verified Zener voltage tolerance, thermal resistance, surge current rating, AEC-Q101 qualification status, and cathode/anode terminal mapping per official Nexperia documentation.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled 13.0 V nominal regulation at IZ = 5 mA, exhibiting low dynamic impedance (103 Ω) and temperature coefficient of +7.0 mV/K at 5 mA. Its junction-to-ambient thermal resistance is 230 K/W on FR4 PCB, enabling stable operation up to 150 °C junction temperature.
The device uses planar epitaxial construction with silicon die in SC-90 package, supporting pulsed reverse power handling up to 40 W (tp = 100 µs, square wave), and features ≤0.1 µA reverse leakage at 10.4 V. It meets AEC-Q101 stress-test requirements for automotive-grade reliability.

Applications
| Automotive Sensor Reference | Microcontroller Reset Circuit |
|---|---|
Use Scenario: Providing stable 13 V reference for analog front-end of pressure/temperature sensors in engine control units.

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-C13,115 | ±5 % tolerance (vs. ±2 %); higher rdiff = 110 Ω; same package and surge rating | Acceptable where cost sensitivity outweighs precision; less suitable for high-accuracy references | Select for non-critical biasing or cost-driven consumer designs where 13 V ±5 % is sufficient |
| MMSZ5243B-7-F | 13 V ±5 %; 500 mW Ptot; SOD-123 package (larger footprint); rdiff = 170 Ω | Lower surge capability (30 W); not AEC-Q101 qualified; requires more PCB area | Choose only if legacy SOD-123 layout exists and automotive qualification is unnecessary |

FAQ
What is the exact Zener voltage tolerance and test condition for BZX84J-B13,115?
The BZX84J-B13,115 has a nominal Zener voltage of 13.0 V with ±2 % tolerance, measured at IZ = 5 mA and Tj = 25 °C. This is confirmed in Table 8 of the official Nexperia datasheet Rev. 3 (2025), where the min/max range is specified as 12.70 V to 13.30 V.
Is BZX84J-B13,115 suitable for automotive applications, and what qualification does it hold?
Yes, the BZX84J-B13,115 is AEC-Q101 qualified per Section 11.1 of the datasheet. It has passed stress tests including temperature cycling, high-temperature operating life, and ESD, making it approved for use in engine control, body electronics, and ADAS subsystems.
What is the maximum non-repetitive peak reverse current IZSM and under what conditions?
The maximum non-repetitive peak reverse current is 2.5 A, defined for tp = 100 µs square-wave pulses with Tj = 25 °C prior to surge, as stated in Table 8 for the B13 variant. This corresponds to the 40 W PZSM rating for ≥7.5 V types.
How does the thermal resistance affect PCB layout for continuous operation?
With Rth(j-a) = 230 K/W on FR4 (single-sided copper, 1 cm² cathode pad), sustained 550 mW dissipation raises junction temperature by ~127 °C above ambient. To stay within 150 °C Tj, ambient must remain ≤23 °C unless enhanced copper pours or thermal vias reduce effective Rth.
