Product details
Overview
BZX84J-B3V6,115 from Nexperia is a 3.6 V ±2 % tolerance Zener diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and 150 °C junction temperature, designed for precision voltage regulation in low-power analog and automotive subsystems.
For engineers reviewing the BZX84J-B3V6,115 datasheet, BZX84J-B3V6,115 pinout, BZX84J-B3V6,115 application, or BZX84J-B3V6,115 equivalent, this device supports stable reference generation under transient surge conditions (IZSM = 12 A, tp = 100 μs), low differential resistance (90 Ω at IZ = 5 mA), and AEC-Q101 qualification for automotive use.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 3.6 V reference across load and line variations, with temperature coefficient of −3.5 to 0 mV/K at IZ = 5 mA. Its low 90 Ω differential resistance ensures minimal output voltage drift under current changes.
The device sustains non-repetitive peak reverse power up to 100 W (≤6.8 V types) with pulse width ≤100 μs and duty cycle ≤0.02, and features 450 pF capacitance at VR = 0 V, f = 1 MHz - suitable for noise-sensitive biasing and feedback networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.53 V to 3.67 V at IZ = 5 mA - defines tight 3.6 V nominal regulation point with ±2 % tolerance |
| Differential Resistance (rdiff) | 90 Ω max at IZ = 5 mA - ensures <3.3 mV output shift per 0.1 mA current change in regulation loop |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - sets maximum 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 |
| Reverse Leakage (IR) | 5 μA max at VR = 1 V - guarantees low quiescent current in high-impedance reference paths |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

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 | ±5 % tolerance (vs. ±2 %), higher rdiff (100 Ω), same package and Ptot | Acceptable where cost sensitivity outweighs precision; not recommended for closed-loop feedback | Select when budget constraints dominate and ±5 % regulation error is acceptable in open-loop biasing |
| MMSZ4685T1G | 3.6 V ±5 %, SOD-123 package (larger), 500 mW Ptot, no AEC-Q101 qualification | Lacks automotive qualification; thermal resistance 300 K/W vs. 230 K/W limits high-temp derating | Use only in commercial-grade consumer devices where AEC-Q101 and compact size are not required |
Compared with BZX84-C3V6,115, the BZX84J-B3V6,115 delivers tighter voltage control and lower dynamic impedance for precision analog circuits; versus MMSZ4685T1G, it offers superior thermal performance and automotive qualification in a smaller footprint - critical for space-constrained ECU designs.

FAQ
What is the maximum continuous forward current for BZX84J-B3V6,115?
The absolute maximum forward current is 250 mA per limiting values table. However, sustained forward conduction is not intended in Zener regulation applications; typical use maintains reverse bias. Forward voltage is 1.1 V at 100 mA, confirming silicon diode behavior but not specifying safe DC forward operation limits beyond brief test conditions.
Does BZX84J-B3V6,115 require external series resistance in regulation circuits?
Yes - a current-limiting resistor is mandatory to set operating current within 1 mA to 20 mA range, ensuring stable Zener voltage and avoiding thermal runaway. For 3.6 V output from 5 V rail, a 100 Ω resistor delivers ~14 mA, staying within 550 mW Ptot and maintaining rdiff <90 Ω.
How does the −3.5 to 0 mV/K temperature coefficient affect regulation accuracy?
This coefficient means output voltage decreases by up to 3.5 mV per °C rise in junction temperature. Over a 100 °C range (−40 °C to +60 °C ambient), worst-case drift is 350 mV - but actual drift is mitigated by low power dissipation and PCB thermal design, typically holding regulation error within ±15 mV in real automotive implementations.
Can BZX84J-B3V6,115 replace BZX84-C3V6 in existing designs?
Yes, with caveats: both share identical SOD323F package, pinout, and 3.6 V nominal voltage, but BZX84J-B3V6,115 offers ±2 % tolerance and AEC-Q101 qualification versus ±5 % and commercial grade for BZX84-C3V6. No layout change is needed, but qualification retesting is required for automotive deployments.
