Product details
Overview
BZX84J-B2V7,115 from Nexperia is a 2.7 V ±2 % tolerance Zener voltage regulator diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and AEC-Q101 qualified for automotive use. It delivers stable reverse breakdown at 2.7 V with 440 Ω differential resistance at 5 mA and supports general-purpose voltage reference and overvoltage protection in space-constrained PCBs.
For engineers reviewing the BZX84J-B2V7,115 datasheet, BZX84J-B2V7,115 pinout, BZX84J-B2V7,115 application, or BZX84J-B2V7,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), low differential resistance (440 Ω), AEC-Q101 qualification, SOD323F footprint compatibility, and non-repetitive surge capability (12 A peak reverse current).
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable 2.7 V reference across load variations. Its ±2 % tolerance and 440 Ω dynamic impedance ensure tight regulation under 5 mA test current, while the negative temperature coefficient (−3.5 mV/K) enables predictable thermal drift compensation in precision circuits.
Designed for surface-mount reliability, it features AEC-Q101 qualification, 150 °C maximum junction temperature, and thermal resistance of 230 K/W (junction-to-ambient on FR4). The SOD323F package supports reflow soldering only and provides cathode identification via a marking bar.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V nominal, ±2 % tolerance - ensures precise 2.65–2.75 V regulation at IZ = 5 mA |
| Differential Resistance (rdiff) | 440 Ω max at IZ = 5 mA - low impedance maintains voltage stability against load current changes |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - defines continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Reverse Current (IZSM) | 12 A at tp = 100 μs - supports transient overvoltage clamping without failure |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - limits forward conduction loss in bidirectional protection schemes |
| Reverse Current (IR) | 100 μA max at VR = 1 V - ensures minimal leakage below breakdown threshold |
| Temperature Coefficient (SZ) | −3.5 mV/K - quantifies predictable downward voltage shift per degree rise in junction temperature |
Pinout & Package
The BZX84J-B2V7,115 is housed in a SOD323F (SC-90) plastic surface-mount package measuring 2.7 mm × 1.6 mm × 0.95 mm, with flat leads and cathode identified by a marking bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar indicates this terminal; reverse-bias anode connection point |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| ±2 % Zener voltage tolerance | Enables tighter system-level voltage margin control vs. ±5 % variants in critical reference paths |
| Low differential resistance (440 Ω) | Reduces output voltage deviation under varying load currents, improving regulation accuracy |
| SOD323F ultra-small footprint | Occupies < 4.3 mm² PCB area - suitable for high-density portable and automotive ECUs |
| 12 A non-repetitive surge capability | Clamps ESD and load-dump transients without degradation when used with series current limiting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C2V7,115 | ±5 % tolerance (2.57–2.83 V), higher rdiff (450 Ω), same package and Ptot | Acceptable where system-level voltage margin allows wider regulation band | Select for cost-sensitive industrial designs where ±2 % precision is not required |
| MMSZ4678T1G | 2.7 V ±5 %, 500 mW Ptot, SOD-123 package (larger footprint), no AEC-Q101 qualification | Limited to commercial-grade applications; incompatible with automotive PCB layouts | Choose only for non-automotive prototypes requiring legacy footprint compatibility |
Compared with BZX84J-B2V7,115, the BZX84-C2V7,115 trades precision for cost, while MMSZ4678T1G sacrifices automotive qualification and board space efficiency - making the BZX84J-B2V7,115 optimal for AEC-Q101-compliant, space-constrained 2.7 V reference designs.

FAQ
What is the maximum continuous power dissipation for BZX84J-B2V7,115?
The BZX84J-B2V7,115 has a total power dissipation (Ptot) limit of 550 mW at ambient temperature ≤25 °C on a standard FR4 PCB with specified copper pad layout. Derating is required above 25 °C at 4.4 mW/°C based on its 230 K/W junction-to-ambient thermal resistance.
Is BZX84J-B2V7,115 suitable for automotive applications?
Yes - it is fully AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and ESD. Its 150 °C maximum junction temperature and guaranteed performance across −55 °C to +150 °C ambient make it approved for under-hood and cabin ECU use.
How is cathode polarity identified on the SOD323F package?
The cathode (pin 1) is marked by a visible bar on the top surface of the SOD323F package body. This aligns with the simplified outline in Nexperia's datasheet Figure 11 and confirms correct orientation during automated placement and manual inspection.
What is the typical Zener impedance at 5 mA test current?
The differential resistance (rdiff) is 440 Ω maximum at IZ = 5 mA and Tj = 25 °C, as specified in Table 8 of the datasheet. This value reflects the slope of the VZ–IZ curve and directly impacts regulation accuracy under dynamic load conditions.
