Product details
Overview
BZX84J-C10,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode with nominal 10 V breakdown voltage, 550 mW total power dissipation, and AEC-Q101 qualification for automotive use in SOD323F (SC-90) surface-mount package. It delivers stable reference voltage in low-power supply rails, ESD protection clamping networks, and overvoltage sensing circuits.
For engineers reviewing the BZX84J-C10,115 datasheet, BZX84J-C10,115 pinout, BZX84J-C10,115 application, or BZX84J-C10,115 equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (150 Ω at IZ = 5 mA), non-repetitive peak reverse power (40 W), junction temperature rating (150 °C), and AEC-Q101 qualification status.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable 10 V reference across its terminals under regulated current conditions. Its 150 Ω differential resistance ensures minimal voltage deviation over load current changes within its 5 mA test condition.
The device features low thermal resistance (Rth(j-a) = 230 K/W on FR4 PCB) and a positive temperature coefficient of +4.5 mV/K at IZ = 5 mA, enabling predictable drift behavior in temperature-varying environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.4 V to 10.6 V at IZ = 5 mA - defines usable regulation window for precision reference applications |
| Differential Resistance (rdiff) | 150 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W at tp = 100 μs - supports transient surge suppression in automotive load-dump or ESD events |
| Reverse Current (IR) | 0.2 μA at VR = 7.6 V - ensures low leakage in high-impedance bias networks |
| Junction Temperature (Tj) | 150 °C maximum - enables operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability per stress-test qualification standard |
Pinout & Package
Package: SOD323F (SC-90), ultra-small flat-lead surface-mount plastic package with 2 terminals, 1.35 mm × 0.80 mm body size, and cathode-marked anode-cathode orientation.

|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node in reverse-bias regulation; marked by bar on package top surface |
| 2 | Anode (A) | Connected to lower-potential node (e.g., ground or return path); establishes forward conduction direction |
Key Features
| Feature | Design Value |
|---|---|
| Low differential resistance | 150 Ω at 5 mA - improves regulation accuracy under varying load currents |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10,115 | Same Zener voltage and tolerance, but not AEC-Q101 qualified; Ptot = 365 mW | Limited to commercial-grade applications; unsuitable for automotive under-hood use | Select when cost sensitivity outweighs automotive qualification requirements |
| MMSZ5240B-7-F | 10 V ±5 %, SOD-123 package, Ptot = 500 mW, no AEC-Q101 qualification | Higher thermal resistance (Rth(j-a) ≈ 300 K/W); less robust under sustained power dissipation | Prefer only for space-constrained designs where SOD-123 footprint is mandated and automotive qualification is unnecessary |
Compared with BZX84J-C10,115, the BZX84-C10,115 offers identical electrical specs but lacks automotive qualification and has lower power handling, while MMSZ5240B-7-F trades package compatibility for reduced thermal performance and no AEC-Q101 validation.

FAQ
What is the Zener voltage tolerance for BZX84J-C10,115?
The BZX84J-C10,115 has a nominal Zener voltage of 10 V with a guaranteed tolerance of ±5 %, meaning the actual breakdown voltage falls between 9.4 V and 10.6 V when tested at 5 mA reverse current and 25 °C junction temperature, as specified in Table 8 of the Nexperia datasheet Rev. 3.
Is BZX84J-C10,115 suitable for automotive applications?
Yes - BZX84J-C10,115 is fully AEC-Q101 qualified per Nexperia's official product data sheet Rev. 3 (2025), confirming compliance with stress-test requirements for discrete semiconductors used in automotive electronics including engine control units, body control modules, and ADAS subsystems.
What is the maximum non-repetitive peak reverse power for this part?
The maximum non-repetitive peak reverse power (PZSM) is 40 W, measured under pulsed conditions of tp = 100 μs, square-wave waveform, and junction temperature of 25 °C prior to surge - applicable to all BZX84J types rated ≥ 7.5 V, including the C10 variant.
How does the differential resistance affect regulation performance?
With a typical differential resistance of 150 Ω at 5 mA, the BZX84J-C10,115 exhibits moderate output impedance - resulting in ~0.75 V change in Zener voltage for every 5 mA variation in reverse current, directly impacting reference stability in low-current bias networks and feedback dividers.
