Product details
Overview
BZX84J-C11,115 from Nexperia is a 11 V ±5 % Zener voltage regulator diode in SOD323F (SC-90) surface-mount package, rated for 550 mW total power dissipation and 150 °C junction temperature, used for precision voltage reference and overvoltage protection in automotive and industrial power rails.
For engineers reviewing the BZX84J-C11,115 datasheet, BZX84J-C11,115 pinout, BZX84J-C11,115 application, or BZX84J-C11,115 equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (150 Ω at IZ = 5 mA), non-repetitive peak reverse power (40 W), AEC-Q101 qualification, and thermal resistance (230 K/W junction-to-ambient).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 11 V regulation across load and line variations, with low differential resistance (150 Ω) ensuring minimal voltage deviation under current changes from 1 mA to 20 mA. Its temperature coefficient of +5.4 mV/K at IZ = 5 mA enables predictable drift compensation in bias networks.
Designed for automotive-grade reliability, it meets AEC-Q101 stress test requirements and supports pulsed surge handling up to 40 W (tp = 100 μs, square wave) for transient suppression in 12 V systems. The SC-90 package provides compact mounting with defined thermal path via cathode pad (Rth(j-sp) = 55 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V nominal, ±5 % tolerance (10.4–11.6 V), defining regulation setpoint accuracy for feedback loops |
| Differential Resistance (rdiff) | 150 Ω at IZ = 5 mA, limiting output voltage variation to ±0.75 V over ±5 mA current change |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C on FR4 PCB, setting maximum continuous DC power handling |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 μs, enabling robust ESD/ISO 7637-2 pulse suppression without failure |
| Reverse Current (IR) | ≤ 0.1 μA at VR = 8.8 V, ensuring negligible leakage in standby or high-impedance sensing nodes |
| Junction Temperature (Tj) | 150 °C max, supporting operation in under-hood automotive environments and industrial enclosures |
| AEC-Q101 Qualified | Validated for automotive discrete semiconductor stress testing, including HTGB, HTRB, and temperature cycling |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal; carries reverse breakdown current |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes reverse-biased path during regulation |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C11,115 | Same Zener voltage and package, but ±5 % tolerance and non-AEC-Q101 qualified; PZSM = 40 W unchanged | Limited to commercial/industrial use; not approved for automotive ECUs or body electronics | Select when AEC-Q101 compliance is unnecessary and cost is primary driver |
| MMSZ5240B-TP | 10 V nominal, ±5 %, SOD-123 package, 500 mW Ptot, 200 Ω rdiff, no AEC-Q101 rating | Lower voltage and higher rdiff reduce regulation accuracy; larger footprint increases board area | Choose only for legacy SOD-123 layout compatibility where 11 V is not required |
Compared with BZX84J-C11,115, the BZX84-C11,115 offers identical electrical specs but lacks automotive qualification, while MMSZ5240B-TP trades voltage accuracy, regulation stiffness, and package size for broader distributor availability - making the J-series optimal for new automotive designs demanding validated reliability.

FAQ
What is the maximum continuous forward current for BZX84J-C11,115?
The absolute maximum forward current (IF) is 250 mA per limiting values table. However, forward conduction is not its intended operating mode; the device is designed for reverse-bias Zener regulation. Sustained forward current above 100 mA risks thermal overstress due to VF ≈ 1.1 V and limited package thermal dissipation.
Can BZX84J-C11,115 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients and manufacturing spread, causing current hogging when paralleled. Even matched units will thermally diverge, leading to premature failure of one device. For higher power, use a single higher-rated Zener or active regulation instead.
How does the ±5 % tolerance affect regulation accuracy in a 12 V automotive system?
At 11 V nominal with ±5 % tolerance, actual VZ ranges from 10.4 V to 11.6 V. In a 12 V system with 100 Ω series resistor, this causes ±60 mV variation in regulated node voltage under 1 mA load - acceptable for non-critical biasing but insufficient for precision references requiring <±10 mV.
Is the SOD323F package compatible with standard reflow profiles for lead-free assembly?
Yes - Nexperia specifies reflow soldering as the only recommended method, and the SOD323F outline complies with JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life). The package withstands peak temperatures up to 260 °C for ≤ 30 seconds, matching IPC/JEDEC Class 3 reflow profiles.
