Product details
Overview
BZX84J-B36,115 from Nexperia is a 36 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 tp = 100 μs, designed for precision voltage regulation in automotive and industrial power rails.
For engineers reviewing the BZX84J-B36,115 datasheet, BZX84J-B36,115 pinout, BZX84J-B36,115 application, or BZX84J-B36,115 equivalent, key selection criteria include Zener voltage tolerance, differential resistance (300 Ω @ IZ = 2 mA), thermal resistance (230 K/W j-a), AEC-Q101 qualification, and SC-90 footprint compatibility.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage under varying load and temperature conditions. Its 36 V nominal Zener voltage is specified at IZ = 2 mA with ±2 % tolerance, and exhibits a positive temperature coefficient of +25.2 mV/K over 25–150 °C.
The device features low differential resistance (300 Ω), low reverse leakage (<0.05 µA @ VR = 27 V), and is qualified per AEC-Q101 for automotive use. Thermal performance is defined with Rth(j-a) = 230 K/W on FR4 PCB with 1 cm² cathode pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 35.3 V to 36.7 V @ IZ = 2 mA - defines tight regulation window for 36 V rail stabilization |
| Tolerance | ±2 % - enables high-accuracy feedback in voltage-controlled loops without trimming |
| Differential Resistance (rdiff) | 300 Ω @ IZ = 2 mA - determines output impedance and load regulation sensitivity |
| Total Power Dissipation (Ptot) | 550 mW @ Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 |
| Non-repetitive Peak Power (PZSM) | 40 W @ tp = 100 μs - supports transient surge suppression in automotive load-dump scenarios |
| Junction Temperature (Tj) | −55 °C to +150 °C - ensures operation across extended automotive ambient ranges |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test qualification for discrete semiconductors |
Pinout & Package
Package: SOD323F (SC-90), ultra-small surface-mount plastic package with flat leads; dimensions 2.7 mm × 1.35 mm × 0.95 mm (L × W × H); 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; carries reverse current during Zener conduction |
| 2 | Anode (A) | Connected to ground or lower-potential reference; completes reverse-biased path for voltage clamping |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics |
| Low differential resistance | 300 Ω @ 2 mA enables <1 % output deviation under ±10 mA load variation |
| Stable temperature coefficient | +25.2 mV/K allows predictable drift compensation in wide-temperature designs |
| Small SOD323F footprint | 0.95 mm height and 1.35 mm width support high-density PCB layouts in space-constrained modules |
| Low reverse leakage | <0.05 µA @ VR = 27 V minimizes quiescent current in battery-backed circuits |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C36,115 | ±5 % tolerance (vs. ±2 %); same SOD323F package and 36 V nominal rating | Lower accuracy acceptable in non-critical biasing; higher production yield | Select when cost sensitivity outweighs regulation precision requirements |
| MMSZ5227B-7-F | 36 V ±5 %, SOD-123 package (larger footprint), 500 mW Ptot, no AEC-Q101 qualification | Suitable for commercial-grade power supplies but not automotive environments | Choose only for non-automotive designs where board space and qualification are secondary |
Compared with BZX84J-B36,115, the BZX84-C36,115 trades tighter tolerance for lower unit cost, while MMSZ5227B-7-F lacks automotive qualification and uses a less compact package-making the J-series part optimal for space-constrained, safety-critical 36 V regulation.

FAQ
What is the maximum continuous forward current for BZX84J-B36,115?
The absolute maximum forward current is 250 mA per limiting values table. However, forward conduction is not its intended operating mode; it is designed for reverse-biased Zener regulation. Continuous forward bias above 100 mA risks exceeding thermal limits due to VF ≈ 1.1 V and resulting power dissipation.
Can BZX84J-B36,115 be used in parallel for higher power handling?
No-Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, slight VZ mismatches cause current hogging. Parallel connection is not recommended; instead, use a single higher-rated device or external current-sharing resistors if absolutely necessary.
How does the 36 V Zener voltage behave across temperature?
At IZ = 2 mA, the temperature coefficient is +25.2 mV/K. This means VZ increases by approximately 25.2 mV per degree Celsius rise in junction temperature, resulting in a +0.7 % shift from 25 °C to 125 °C-critical for high-precision references requiring drift compensation.
Is the SOD323F package compatible with standard reflow soldering profiles?
Yes-Nexperia specifies reflow soldering as the only recommended method. The SC-90 outline supports JEDEC J-STD-020-compliant profiles, with peak temperature ≤ 260 °C and time above liquidus ≤ 60 seconds. Pad layout must follow Figure 12 (0.5 mm × 0.6 mm lands, 0.6 mm spacing).
