Product details
Overview
BZX84J-C36,115 from Nexperia is a 36 V ±5 % Zener voltage regulator diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and 150 °C junction temperature, with low differential resistance (300 Ω at IZ = 2 mA) and AEC-Q101 qualification for automotive voltage reference and overvoltage protection circuits.
For engineers reviewing the BZX84J-C36,115 datasheet, BZX84J-C36,115 pinout, BZX84J-C36,115 application, or BZX84J-C36,115 equivalent, this device serves as a precision shunt voltage reference in low-power analog monitoring, ECU supply rail clamping, and sensor biasing where stable 36 V regulation under transient surge conditions is required.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 36 V reference across its cathode-anode terminals when reverse-biased above its nominal Zener voltage, with specified test current of 2 mA and maximum non-repetitive peak reverse power dissipation of 40 W (tp = 100 μs, square wave).
Its thermal resistance from junction to ambient is 230 K/W on FR4 PCB, and it exhibits a positive temperature coefficient of +25.2 mV/K at IZ = 2 mA, enabling predictable drift behavior in temperature-sensitive regulation paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 34.0 V to 38.0 V at IZ = 2 mA - defines regulated output voltage range under nominal bias |
| Differential Resistance (rdiff) | 300 Ω max at IZ = 2 mA - determines regulation stiffness and load-induced voltage deviation |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - sets continuous DC power handling limit on standard FR4 board |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W at tp = 100 μs - supports transient overvoltage suppression without failure |
| Reverse Current (IR) | 0.05 μA max at VR = 27 V - ensures minimal leakage below breakdown threshold |
| 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 |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C36,115 | Same 36 V ±5 % rating but not AEC-Q101 qualified; PZSM = 40 W unchanged | Limited to industrial/commercial use; lacks automotive reliability validation | Select only if automotive qualification is unnecessary and cost sensitivity outweighs long-term field reliability needs |
| MMSZ5245B-TP | 36 V ±5 %, SOD-123 package, Ptot = 500 mW, rdiff = 350 Ω - larger footprint, higher rdiff, no AEC-Q101 | Compatible in non-automotive PCBs with available SOD-123 land pattern; lower surge margin | Choose when existing layout uses SOD-123 and AEC-Q101 is not mandated |
Compared with BZX84-C36,115 and MMSZ5245B-TP, the BZX84J-C36,115 uniquely combines AEC-Q101 qualification, SOD323F miniaturization, and 300 Ω differential resistance-making it the only option for space-constrained automotive voltage references requiring production-grade reliability.

FAQ
What is the maximum continuous reverse current the BZX84J-C36,115 can handle at 25 °C?
The device has no defined maximum continuous reverse current rating; instead, its safe operating area is governed by total power dissipation (550 mW at Tamb ≤ 25 °C). At 36 V Zener voltage, this corresponds to ~15.3 mA average reverse current. Exceeding this causes junction temperature rise beyond 150 °C, risking thermal runaway.
Can the BZX84J-C36,115 be used in parallel for higher power handling?
No-Zener diodes exhibit negative temperature coefficients at low voltages but positive above ~5.6 V; the BZX84J-C36,115 has +25.2 mV/K, causing current hogging if paralleled without individual ballast resistors. Even with balancing, derating is required due to thermal coupling, making discrete parallel use unreliable.
How does the marking code 'U7' correspond to BZX84J-C36,115?
Per Table 4 in the datasheet, 'U7' is the standardized top-side marking for BZX84J-C36,115. The 'U' prefix denotes the C-tolerance (±5 %) variant, and '7' identifies the 36 V nominal voltage within the C-series sequence-enabling visual identification on assembled PCBs.
Is the SOD323F package compatible with standard reflow soldering profiles?
Yes-the datasheet explicitly states reflow soldering is the only recommended method. The SC-90 outline (Fig. 12) specifies a 0.5 mm pad width and 0.6 mm spacing; JEDEC J-STD-020-compliant profiles with peak temperature ≤ 260 °C and time above liquidus ≤ 60 s ensure reliable joint formation without package damage.
