Product details
Overview
BZX84J-C13,115 from Nexperia is a 13 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 100 µs pulse width, used for precision voltage reference and overvoltage clamping in automotive and industrial power rails.
For engineers reviewing the BZX84J-C13,115 datasheet, BZX84J-C13,115 pinout, BZX84J-C13,115 application, or BZX84J-C13,115 equivalent, this device delivers AEC-Q101-qualified Zener regulation with low differential resistance (170 Ω at IZ = 5 mA), temperature coefficient of +7.0 mV/K, and reverse current ≤0.1 µA at 10.4 V - critical for stable biasing and protection in compact SMT designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 13 V reference across load variations, with a nominal Zener voltage tolerance of ±5 % and specified test current of 5 mA. Its differential resistance of 170 Ω ensures minimal output voltage drift under dynamic current conditions.
Designed for automotive-grade reliability, it meets AEC-Q101 stress qualification and supports operation from −55 °C to +150 °C ambient, with thermal resistance from junction to ambient of 230 K/W on standard FR4 PCB mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.4 V to 14.1 V at IZ = 5 mA - defines regulated output range for reference or clamp function |
| Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard PCB |
| Differential Resistance (rdiff) | 170 Ω at IZ = 5 mA - determines voltage regulation accuracy under load current variation |
| Temperature Coefficient (SZ) | +7.0 mV/K - quantifies Zener voltage drift per degree Celsius rise in junction temperature |
| Reverse Current (IR) | ≤ 0.1 µA at VR = 10.4 V - ensures low leakage before breakdown onset |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - enables transient overvoltage suppression without failure |
| Junction Temperature (Tj) | 150 °C maximum - defines absolute thermal limit for safe long-term operation |
Pinout & Package
The BZX84J-C13,115 is housed in a SOD323F (SC-90) surface-mount plastic package measuring 2.7 mm × 1.6 mm × 0.95 mm, with flat leads optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode (K) | Connected to higher-potential node in reverse-bias configuration; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to lower-potential node (e.g., ground or return path); completes reverse-bias circuit for Zener action |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics use including engine control, body modules, and ADAS power domains |
| Low differential resistance | 170 Ω at 5 mA enables tight voltage regulation under varying load currents |
| Wide operating temperature | −55 °C to +150 °C ambient rating supports under-hood and industrial environments |
| SOD323F package | 0.65 mm lead pitch and 1.6 mm width enable high-density routing in space-constrained PCBs |
| ±5 % Zener tolerance | Guarantees 12.4–14.1 V regulation window for predictable clamping or reference behavior |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13,115 | Same Zener voltage and package, but lacks AEC-Q101 qualification and has ±6 % tolerance (vs. ±5 %) | Not suitable for automotive or safety-critical industrial use; acceptable for consumer-grade power monitoring | Select only if AEC-Q101 compliance and tighter tolerance are not required |
| MMSZ4687T1G | 13 V Zener, SOD-123 package (larger footprint), ±5 % tolerance, 500 mW Ptot, no AEC-Q101 rating | Higher thermal resistance (300 K/W) limits power handling in compact layouts; unsuitable for automotive | Choose when board space permits larger package and automotive qualification is unnecessary |
Compared with BZX84-C13,115 and MMSZ4687T1G, the BZX84J-C13,115 uniquely combines AEC-Q101 qualification, ±5 % tolerance, and SOD323F size - making it the only option for space-constrained automotive voltage clamping where long-term parametric stability is mandatory.

FAQ
What is the maximum continuous forward current for BZX84J-C13,115?
The absolute maximum forward current is 250 mA per limiting values table. However, forward conduction is not its intended operating mode; the device is designed for reverse-bias Zener regulation. Continuous forward bias above 100 mA risks thermal overstress due to VF ≈ 1.1 V and limited Ptot = 550 mW.
Can BZX84J-C13,115 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. The BZX84J-C13,115's 170 Ω rdiff does not ensure balanced sharing; parallel use risks thermal runaway and premature failure.
How does the +7.0 mV/K temperature coefficient affect regulation accuracy?
At 13 V nominal, +7.0 mV/K means voltage increases by ~0.7 V over a 100 °C junction rise. For example, from 25 °C to 125 °C, VZ shifts from 13.0 V to ~13.7 V. This must be factored into system-level tolerance budgets for precision references or clamps operating across wide temperature ranges.
Is the SOD323F package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method. The SOD323F outline supports JEDEC J-STD-020-compliant profiles, with peak temperatures up to 260 °C. Pad layout per Figure 12 (0.5 mm × 0.6 mm lands, 0.6 mm spacing) ensures reliable wetting and mechanical integrity.
