Product details
Overview
BZX84J-C3V6,115 from Nexperia is a 3.6 V ±5 % Zener voltage regulator diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and 100 mA forward current, with low differential resistance (≤90 Ω at IZ = 5 mA) and AEC-Q101 qualification for automotive voltage reference and overvoltage protection circuits.
For engineers reviewing the BZX84J-C3V6,115 datasheet, BZX84J-C3V6,115 pinout, BZX84J-C3V6,115 application, or BZX84J-C3V6,115 equivalent, key selection criteria include Zener tolerance (±5 %), non-repetitive surge capability (12 A peak reverse current), thermal resistance (230 K/W junction-to-ambient), and SC-90 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 3.6 V regulation across load and line variations, with temperature coefficient of −3.5 to 0 mV/K at IZ = 5 mA, enabling predictable drift behavior in ambient ranges from −55 °C to +150 °C.
Its 90 Ω typical differential resistance at 5 mA ensures minimal output voltage variation under dynamic current changes, while the 1.1 V forward voltage at 100 mA supports bidirectional clamping and ESD protection functions in low-voltage signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.6 V nominal, ±5 % tolerance (3.4 V to 3.8 V), defines precise regulation threshold for 3.3 V rail supervision |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C on FR4 PCB, sets continuous thermal limit for compact SMT placement |
| Differential Resistance (rdiff) | ≤90 Ω at IZ = 5 mA, determines regulation stiffness against load current transients |
| Non-repetitive Peak Reverse Current (IZSM) | 12 A at tp = 100 μs, enables transient overvoltage suppression without failure |
| Forward Voltage (VF) | 1.1 V at IF = 100 mA, supports dual-role use as clamp and rectifier in bidirectional protection schemes |
| Junction Temperature (Tj) | 150 °C maximum, allows operation in under-hood automotive environments with derated power |
| AEC-Q101 Qualified | Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD (HBM ≥ 2 kV) |
Pinout & Package
SOD323F (SC-90) surface-mount plastic package: 2.3 mm × 1.35 mm body, 0.65 mm height, 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 for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Meets automotive stress test requirements for HTOL, temperature cycling, and ESD robustness |
| Low differential resistance | ≤90 Ω at 5 mA ensures <10 mV output shift per 1 mA load change in regulation mode |
| Small SOD323F footprint | 2.3 mm × 1.35 mm area enables placement in space-constrained modules like ADAS sensors and ECUs |
| Wide operating temperature | −55 °C to +150 °C junction range supports engine bay and powertrain applications |
| Two tolerance options | ±2 % (B-series) and ±5 % (C-series) allow cost/performance trade-off in production BOMs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V6,115 | Same Zener voltage and tolerance, but not AEC-Q101 qualified; 500 mW Ptot vs. 550 mW | Limited to industrial/commercial grade; unsuitable for automotive under-hood deployment | Select when AEC-Q101 is not required and cost sensitivity outweighs 50 mW power margin |
| MMSZ5226B-7-F | 3.3 V nominal, ±5 %, SOD-123 package (larger footprint), 500 mW Ptot, higher rdiff (140 Ω) | Requires PCB redesign; less stable regulation under load transients due to higher impedance | Choose only if legacy SOD-123 layout exists and 0.3 V lower Zener voltage is acceptable |
Compared with BZX84J-C3V6,115, the BZX84-C3V6,115 lacks automotive qualification and has lower power handling, while MMSZ5226B-7-F uses a larger package and delivers inferior regulation stability-making the J-series the optimal choice for new automotive and high-reliability designs requiring SC-90 footprint and AEC-Q101 compliance.

FAQ
What is the maximum continuous Zener current for BZX84J-C3V6,115 at 25 °C ambient?
The device supports up to 153 mA continuous Zener current at 25 °C ambient, calculated from Ptot = 550 mW and VZ = 3.6 V (IZ = Ptot/VZ). Derating begins above 25 °C at 4.4 mW/°C based on Rth(j-a) = 230 K/W, reaching zero allowable current at 150 °C junction temperature.
How does the cathode marking appear on the SOD323F package?
The cathode is identified by a single black bar printed on the top surface of the SOD323F package, aligned with pin 1. The physical outline shows pin 1 on the left when the marking bar is oriented horizontally at the top edge, matching the simplified graphic symbol in Nexperia's pinning diagram.
Can BZX84J-C3V6,115 be used for bidirectional ESD protection?
Yes-it provides bidirectional clamping: forward conduction limits positive transients to ≤1.1 V at 100 mA, while reverse Zener action clamps negative surges to 3.6 V. Its 12 A non-repetitive peak current rating and AEC-Q101 ESD validation (HBM ≥ 2 kV) confirm suitability for I/O line protection in automotive interfaces.
What is the thermal resistance from junction to solder point (Rth(j-sp)) and why does it matter?
Rth(j-sp) is 55 K/W, measured from junction to cathode solder point in free air. This value matters because it governs localized heating during short-duration surges: for a 100 μs, 12 A pulse, junction temperature rise is ~36 °C above solder point, enabling reliable transient absorption without thermal runaway when properly soldered to adequate copper.
