Product details
Overview
BZX84J-C16,115 from Nexperia is a 16 V ±5 % Zener voltage regulator diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and 40 W non-repetitive peak reverse power at tp = 100 μs, used for precision voltage reference and overvoltage clamping in automotive and industrial power rails.
For engineers reviewing the BZX84J-C16,115 datasheet, BZX84J-C16,115 pinout, BZX84J-C16,115 application, or BZX84J-C16,115 equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (≤ 20 Ω at IZ = 5 mA), AEC-Q101 qualification, thermal resistance (Rth(j-a) = 230 K/W), and SC-90 surface-mount compatibility.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 16 V regulation across load and line variations, with low differential resistance (11.2 Ω typical at 5 mA) ensuring minimal voltage drift under current changes. Its temperature coefficient of +10.4 mV/K at 5 mA enables predictable thermal behavior in bias networks.
AEC-Q101 qualification confirms robustness for automotive environments, while the SOD323F package supports high-density PCB layouts with verified thermal performance on FR4 (Rth(j-sp) = 55 K/W to solder point). Non-repetitive surge capability (IZSM = 1.5 A, tp = 100 μs) provides transient overvoltage protection without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.3 V to 17.1 V at IZ = 5 mA - defines nominal regulation point with ±5 % tolerance for stable reference accuracy |
| Differential Resistance (rdiff) | ≤ 20 Ω at IZ = 5 mA - ensures < 100 mV output shift per 5 mA load change, critical for low-noise analog references |
| 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 ESD and surge suppression up to 1.5 A transient current without failure |
| Reverse Current (IR) | ≤ 0.05 μA at VR = 12.8 V - guarantees negligible leakage below regulation threshold, preserving standby power integrity |
| Forward Voltage (VF) | 1.1 V at IF = 100 mA - enables use as polarity-sensitive clamp or series rectifier in dual-rail protection schemes |
| Junction Temperature (Tj) | −55 °C to +150 °C - validated operation across full automotive ambient range without parameter shift or reliability loss |
Pinout & Package
The BZX84J-C16,115 is housed in a SOD323F (SC-90) plastic surface-mount package measuring 2.7 mm × 1.6 mm × 0.95 mm, with gull-wing leads optimized for reflow soldering on high-density PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated voltage node; marking bar identifies this terminal for correct orientation during placement |
| 2 | Anode (A) | Ground or lower-potential reference point; reverse-biased connection establishes Zener conduction path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock per discrete semiconductor stress test standard |
| Low differential resistance | 11.2 Ω typical at 5 mA - reduces output impedance for improved regulation under dynamic load conditions |
| Wide voltage range support | Part of 74-type series covering 2.4 V to 75 V - enables single-source procurement across multiple board-level voltage rails |
| Small-footprint SMD package | SOD323F footprint occupies only 4.3 mm² - allows integration into space-constrained modules like ADAS sensors and body control units |
| Controlled temperature coefficient | +10.4 mV/K at 5 mA - enables predictable drift compensation in temperature-critical bias networks |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Clamping 24 V supply rail transients induced by relay switching or load dump events. IC Role / Device Role / Timing Role: Zener-based overvoltage clamp placed between rail and ground, conducting only above 16 V threshold.

IC Role / Device Role / Timing Role: Reverse-biased shunt regulator across input terminals, sinking fault current when voltage exceeds 16 V. Use Value: Absorbs up to 40 W surge energy (100 μs), preventing latch-up or destruction of precision op-amps and ADC front-ends. |
| Consumer Smart Meter Power Supply | Medical Infusion Pump Reference Stability |

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 | Same Zener voltage and tolerance, but not AEC-Q101 qualified; PZSM = 40 W unchanged | Limited to commercial/industrial use; unsuitable for automotive ECUs or ADAS modules | Select when cost sensitivity outweighs automotive qualification requirement |
| MMSZ5245B-TP | 15 V nominal, ±5 %, SOD-123 package; rdiff = 17 Ω; Ptot = 500 mW; no AEC-Q101 rating | Lower voltage rating and reduced surge capability (PZSM = 20 W); larger footprint increases layout area by 40 % | Choose only if 15 V regulation suffices and automotive compliance is not required |
Compared with BZX84J-C16,115, the BZX84-C16,115 lacks automotive qualification but matches electrical specs, while MMSZ5245B-TP trades 1 V lower regulation, higher rdiff, and smaller surge margin for broader distributor availability - making the J-series optimal where AEC-Q101 and precise 16 V clamping are mandatory.

FAQ
What is the maximum continuous reverse current the BZX84J-C16,115 can sustain?
The device has no specified maximum continuous reverse current; its steady-state operation is governed by total power dissipation (550 mW). At 16 V, this limits continuous Zener current to 34.4 mA. Exceeding this causes junction temperature rise beyond 150 °C, risking thermal runaway.
Does the BZX84J-C16,115 require a series current-limiting resistor in all applications?
Yes - a series resistor is mandatory to limit Zener current within Ptot and prevent thermal failure. For example, with a 24 V source and 16 V regulation, a minimum 232 Ω resistor is needed to restrict current to 34.4 mA at full power.
How does the ±5 % tolerance affect regulation accuracy in precision circuits?
At 16 V nominal, ±5 % means actual VZ ranges from 15.3 V to 17.1 V. In precision references, this introduces up to ±0.9 V absolute error; designers must account for it in feedback divider ratios or select tighter-tolerance variants (e.g., BZX84J-B16 for ±2 %).
Can the BZX84J-C16,115 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients and mismatched VZ values, causing current hogging and thermal instability when paralleled. For higher power, use a single higher-rated device or active regulation instead.
