Product details
Overview
BZX84J-C22,115 from Nexperia is a 22 V ±5 % Zener voltage regulator diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and 150 °C junction temperature, with 250 mA forward current capability and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX84J-C22,115 datasheet, BZX84J-C22,115 pinout, BZX84J-C22,115 application, or BZX84J-C22,115 equivalent, this device serves as a precision shunt voltage reference in low-power supply regulation, overvoltage protection, and voltage-clamping circuits where tight tolerance, thermal stability, and automotive-grade reliability are required.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 22 V reference across its terminals at IZ = 5 mA, with differential resistance of 250 Ω ensuring minimal voltage shift under load variation. Its temperature coefficient of +16.4 mV/K at 25 °C to 150 °C enables predictable drift behavior in thermal cycling environments.
The device supports non-repetitive peak reverse power dissipation up to 40 W (tp = 100 μs, square wave), enabling transient surge suppression in 12 V/24 V automotive subsystems. Reverse leakage remains ≤0.05 μA at VR = 17.6 V, supporting low-quiescent-current biasing in sensor interfaces and microcontroller reset circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V nominal, ±5 % tolerance - ensures stable reference within 20.9–23.1 V at IZ = 5 mA for accurate voltage clamping. |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - defines maximum continuous DC power handling on standard FR4 PCB with 1 cm² cathode pad. |
| Differential Resistance (rdiff) | 250 Ω at IZ = 5 mA - quantifies output impedance; lower values improve regulation against current load changes. |
| Reverse Leakage Current (IR) | ≤0.05 μA at VR = 17.6 V - enables ultra-low standby current in battery-backed circuits and precision bias networks. |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 μs - supports ESD and load-dump transient suppression without permanent degradation. |
| Junction Temperature (Tj) | 150 °C maximum - allows operation in under-hood automotive environments and industrial enclosures with elevated ambient temperatures. |
| AEC-Q101 Qualified | Yes - validated for automotive applications including engine control units, body electronics, and ADAS sensors per stress test requirements. |
Pinout & Package
SOD323F (SC-90) surface-mount plastic package: 2-terminal, ultra-small footprint (2.3 × 1.35 mm), flat lead, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal; carries reverse-biased current during Zener operation. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path; must be routed with low-inductance trace for transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 compliant - qualified for use in automotive ECUs, lighting modules, and infotainment systems requiring long-term reliability. |
| Low differential resistance | 250 Ω at 5 mA - minimizes output voltage deviation under varying load currents, improving regulation accuracy in feedback paths. |
| Wide operating temperature range | −55 °C to +150 °C - supports deployment in extreme environments including engine compartments and industrial motor drives. |
| Precision voltage tolerance | ±5 % at 22 V - provides tighter regulation than standard ±10 % Zeners, reducing need for post-regulation trimming in analog signal chains. |
| Small-form-factor packaging | SOD323F (SC-90) - enables high-density PCB layouts in space-constrained modules such as telematics units and smart sensors. |
Applications
| Automotive Voltage Clamp | Microcontroller Reset Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C22,115 | Same 22 V ±5 % rating but lacks AEC-Q101 qualification; PZSM = 40 W unchanged; rdiff = 250 Ω identical. | Not approved for automotive use; suitable only for commercial/industrial designs without automotive reliability requirements. | Select when cost sensitivity outweighs automotive qualification needs and thermal cycling is limited to <125 °C. |
| MMSZ5248B-TP | 22 V ±5 %, SOD-123 package (larger footprint), Ptot = 500 mW, rdiff = 350 Ω, no AEC-Q101 listing. | Higher thermal resistance limits sustained power handling; less suitable for high-temperature automotive PCBs. | Choose only if SOD-123 footprint compatibility is mandatory and surge immunity is secondary to board-level assembly simplicity. |
Compared with BZX84J-C22,115, the BZX84-C22,115 offers identical electrical performance but omits automotive qualification-reducing cost where AEC compliance is unnecessary. The MMSZ5248B-TP trades smaller size for higher rdiff and lower Ptot, limiting its utility in thermally demanding or high-surge applications.

FAQ
What is the maximum continuous reverse current the BZX84J-C22,115 can sustain at 25 °C?
The device has no specified maximum continuous reverse current; instead, it is rated for 550 mW total power dissipation at Tamb ≤ 25 °C. At 22 V Zener voltage, this corresponds to ~25 mA average reverse current under steady-state conditions. Exceeding this value risks thermal runaway unless heatsinking or derating is applied per Rth(j-a) = 230 K/W.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At 22 V, the BZX84J-C22,115 exhibits a typical temperature coefficient of +16.4 mV/K. Over a 165 K span, this yields ~2.7 V total drift-approximately ±6.1 % of nominal VZ. For high-accuracy applications, this drift must be compensated in system calibration or mitigated via temperature-aware software correction.
Can this Zener diode replace a 24 V Zener in an existing design?
No-BZX84J-C22,115 is strictly a 22 V device with ±5 % tolerance (20.9–23.1 V). Substituting it for a 24 V Zener would cause premature clamping and potential system malfunction. A direct replacement requires BZX84J-C24,115 (24 V ±5 %), which shares identical package, power rating, and qualification.
Is the SOD323F package compatible with standard reflow soldering profiles?
Yes-Nexperia specifies reflow soldering as the only recommended method. The SOD323F outline supports JEDEC J-STD-020-compliant profiles, with peak temperature ≤260 °C and time above liquidus ≤60 seconds. Thermal pad layout must follow Figure 12 (0.5 mm × 0.6 mm solder lands, 0.6 mm spacing) to ensure mechanical integrity and thermal performance.
