Product details
Overview
BZX84J-B16,115 from Nexperia is a 16 V ±2 % tolerance Zener diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and 40 W non-repetitive peak reverse power at 100 µs pulse width, used for precision voltage regulation and overvoltage protection in automotive and industrial power rails.
For engineers reviewing the BZX84J-B16,115 datasheet, BZX84J-B16,115 pinout, BZX84J-B16,115 application, or BZX84J-B16,115 equivalent, this device offers AEC-Q101 qualification, low differential resistance (≤11.2 Ω at IZ = 5 mA), and stable temperature coefficient (10.4 mV/K typical), critical for ECU reference design and rail clamp circuits.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 16 V at 5 mA test current, exhibiting a differential resistance of ≤11.2 Ω and temperature coefficient of +10.4 mV/K - enabling stable regulation across -55 °C to +150 °C ambient range.
Its SC-90 package delivers thermal resistance of 230 K/W (junction-to-ambient) on FR4 PCB and supports reflow-only soldering; cathode identification is marked by a bar on the device body per Table 2 and Figure 11.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.7–16.3 V at IZ = 5 mA - ensures tight regulation within ±2 % tolerance for 12 V/15 V rail clamping |
| Differential Resistance (rdiff) | ≤11.2 Ω at IZ = 5 mA - minimizes output voltage deviation under load transients |
| Temperature Coefficient (SZ) | +10.4 mV/K - predictable positive drift enables compensation in temperature-sensitive references |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - supports continuous operation in compact SMT layouts with minimal heatsinking |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - handles ESD and surge events per IEC 61000-4-2 without degradation |
| Reverse Current (IR) | ≤0.05 µA at VR = 12.8 V - ensures low leakage in standby power domains |
| Junction Temperature (Tj) | 150 °C maximum - enables reliable operation in under-hood automotive environments |
Pinout & Package
The BZX84J-B16,115 is housed in a SOD323F (SC-90) surface-mount plastic package measuring 2.7 × 1.35 × 0.95 mm (L × W × H), with gull-wing leads optimized for reflow soldering per Figure 12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal - reverse-biased during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes bias path for controlled breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and ESD testing - suitable for engine control and ADAS modules |
| ±2 % Zener voltage tolerance | Tighter than standard ±5 % variants - reduces calibration overhead in precision reference designs |
| Low differential resistance | ≤11.2 Ω at 5 mA - maintains regulation accuracy under dynamic load steps up to 100 mA |
| Small SOD323F footprint | 2.7 × 1.35 mm area - enables high-density placement on space-constrained PCBs in infotainment and body control units |
| Pulsed surge capability | 40 W non-repetitive peak power at 100 µs - suppresses ISO 7637-2 transient spikes without external TVS |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16,115 | ±5 % tolerance (15.2–16.8 V), higher rdiff (≤12 Ω), same package and PZSM | Acceptable where tighter regulation not required; lower cost for non-critical biasing | Select for cost-sensitive consumer applications where ±5 % VZ meets system margin |
| MMSZ4687T1G | 16 V ±5 %, SOD-123 package (3.7 × 1.6 mm), Ptot = 500 mW, rdiff = 30 Ω | Larger footprint and higher resistance limit use in high-precision or space-constrained designs | Choose only if SOD-123 is already standardized in legacy layout and 30 Ω rdiff is acceptable |
Compared with BZX84J-B16,115, the BZX84-C16,115 trades regulation accuracy for cost, while MMSZ4687T1G sacrifices both precision and board area efficiency - making the BZX84J-B16,115 optimal for new automotive and industrial designs demanding AEC-Q101 compliance and tight tolerance.

FAQ
What is the maximum continuous forward current for BZX84J-B16,115?
The absolute maximum forward current is 250 mA per Table 5. However, forward conduction is not its intended operating mode; it is designed for reverse-bias Zener regulation. Continuous forward bias above 100 mA risks exceeding thermal limits due to VF ≈ 1.1 V at that current, leading to localized heating and potential parameter shift.
Can BZX84J-B16,115 replace BZX84-C16 in an existing design?
Yes, electrically and physically - both share identical SOD323F package, pinout, and 16 V nominal rating. However, BZX84J-B16 offers ±2 % tolerance versus ±5 % for the C-series, so replacement improves regulation accuracy but may require verification of downstream circuit margin if previously designed to worst-case C-series spread.
Is thermal derating required above 25 °C ambient?
Yes. With Rth(j-a) = 230 K/W on FR4, the allowable power must be linearly reduced above 25 °C. At 85 °C ambient, maximum continuous dissipation drops to approximately 300 mW to maintain Tj ≤ 150 °C - calculated as Pmax = (150 − 85) / 230 ≈ 0.283 W.
Does the marking 'SD' correspond exclusively to BZX84J-B16,115?
Yes. Per Table 4, 'SD' is the unique marking code for BZX84J-B16 across all production lots. No other type in the BZX84J series uses this code - it appears only on 16 V ±2 % devices in SOD323F packaging, enabling unambiguous visual identification on assembled PCBs.
