Product details
Overview
BZX384-B13,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 13 V nominal breakdown voltage at 5 mA, 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves as a precision reference or overvoltage clamp in low-power analog signal conditioning and power rail stabilization circuits.
For engineers reviewing the BZX384-B13,115 datasheet, BZX384-B13,115 pinout, BZX384-B13,115 application, or BZX384-B13,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), thermal resistance (415 K/W junction-to-ambient), differential resistance (≤170 Ω at IZ = 5 mA), and SOD323 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage across its terminals under varying load or supply conditions. Its temperature coefficient of +7.0 mV/K at IZ = 5 mA ensures predictable drift behavior in ambient temperature ranges from −65 °C to +150 °C.
The device exhibits ≤170 Ω dynamic impedance at 5 mA test current and supports non-repetitive surge handling up to 40 W for 100 μs pulses, enabling transient suppression in DC bias networks without external series limiting resistors in low-energy scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.7 V to 13.3 V at IZ = 5 mA - defines regulated output voltage window under standard test conditions |
| Tolerance | ±2 % - guarantees tight voltage accuracy for reference-grade applications requiring minimal calibration |
| Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Differential Resistance (rdif) | ≤170 Ω at IZ = 5 mA - determines regulation stiffness and output voltage variation under load changes |
| Reverse Current (IR) | ≤30 μA at VR = 10.4 V - specifies leakage level below breakdown, critical for low-power standby circuits |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - enables use as a low-drop rectifier or ESD protection element in bidirectional paths |
| Thermal Resistance (Rth(j-a)) | 415 K/W - quantifies self-heating impact; requires derating above 25 °C ambient for sustained operation |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package with 2 leads, 1.35 mm × 0.85 mm body size, 0.45 mm lead pitch, and cathode-marked 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; reverse-bias polarity must be maintained for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMD package | SOD323 footprint enables placement in space-constrained designs such as portable sensors and wearables |
| Stable ±2 % voltage tolerance | Reduces need for post-production trimming in voltage reference circuits for ADCs and comparators |
| 40 W surge capability | Withstands brief transients without degradation, supporting basic overvoltage protection in 12 V rail monitoring |
| 150 °C max junction temperature | Allows operation in thermally demanding environments like automotive cabin electronics or industrial controllers |
| 100 ns response time | Enables fast clamping of fast-rising ESD events when used with appropriate series impedance |
Applications
| Industrial Sensor Signal Conditioning | USB-C Power Delivery Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5243B | 13 V nominal, ±5 % tolerance, 350 mW Ptot, SOT-23 package | Higher power but looser tolerance; larger footprint increases board area by 40 % | Select when higher surge margin is needed and ±5 % regulation error is acceptable |
| Vishay BZX384-C13 | 13 V nominal, ±5 % tolerance, same SOD323 package and 300 mW rating | Wider voltage spread (12.4–14.1 V) reduces reference accuracy but improves yield in cost-sensitive consumer designs | Select for cost-driven applications where tighter tolerance is not required |
Compared with BZX384-B13,115, MMBZ5243B offers higher power but sacrifices accuracy and board space efficiency, while BZX384-C13 retains identical form factor and power but trades ±2 % precision for broader tolerance and lower unit cost.

FAQ
What is the maximum continuous reverse current the BZX384-B13,115 can sustain at 25 °C ambient?
The device does not specify a maximum continuous reverse current; instead, it is characterized by Zener test current (IZ = 5 mA) and total power dissipation limit of 300 mW. At 13 V, this corresponds to a maximum sustainable Zener current of approximately 23 mA under ideal thermal conditions (Tamb = 25 °C, no PCB copper heatsinking).
Can BZX384-B13,115 be used in place of a 12 V Zener diode?
No - BZX384-B13,115 is specified for 13 V nominal breakdown (12.7–13.3 V range). Substituting it for a 12 V Zener would raise regulated voltage by ~1 V, potentially exceeding downstream component ratings. For 12 V regulation, use BZX384-B12 (11.8–12.2 V) or BZX384-A12 (11.9–12.1 V).
Is the SOD323 package compatible with standard reflow soldering profiles?
Yes - Nexperia provides validated reflow soldering footprints for SOD323 in its datasheet (Figure 12), specifying 0.5 mm pad width, 0.6 mm pad length, and 1.5 mm center-to-center spacing. The device is rated for JEDEC J-STD-020D-compliant peak temperatures up to 260 °C for 30 seconds.
Does BZX384-B13,115 meet automotive qualification standards?
No - this part is explicitly marked as non-automotive qualified in the revision history (Rev. 4, January 2023). Nexperia offers separate automotive-qualified variants (e.g., BZX384-Q series) with AEC-Q101 testing, extended temperature range, and enhanced reliability screening for vehicle applications.
