Product details
Overview
BZT52C15S-7 from Diodes Incorporated is a surface-mount Zener diode with nominal 15 V zener voltage (13.8–15.6 V range at 5 mA), 200 mW power dissipation, and SOD323 package. It provides precise voltage regulation in low-power biasing, reference, and overvoltage protection circuits for automotive and industrial control modules.
For engineers reviewing the BZT52C15S-7 datasheet, BZT52C15S-7 pinout, BZT52C15S-7 application, or BZT52C15S-7 equivalent, key selection criteria include zener voltage tolerance (±4.7%), temperature coefficient (+10.5 mV/°C), reverse leakage (<0.1 µA @ 13.0 V), and AEC-Q101 qualification for automotive reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load conditions. Its planar die construction ensures consistent breakdown characteristics, while the SOD323 package supports high-density PCB layouts and automated reflow assembly.
The device exhibits a positive temperature coefficient of +10.5 mV/°C above 5 V, enabling predictable drift compensation in reference designs. With 30 Ω dynamic impedance at 5 mA test current and <0.1 µA reverse leakage at VR = 13.0 V, it delivers tight regulation for precision analog monitoring circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5245BS-7-F | Zener voltage 15 V (14.25–15.75 V), 350 mW PD, SOT-23 package | Larger footprint and higher power handling; less suitable for ultra-dense layouts | Select when higher surge energy absorption is required and board space permits SOT-23 |
| BZX384-C15 | Zener voltage 15 V (14.3–15.7 V), 300 mW PD, SOD-323 package, ±5% tolerance | Narrower voltage tolerance (±3.3% vs ±4.7%) but no AEC-Q101 qualification | Select for cost-sensitive industrial applications where automotive qualification is not mandated |
Compared with MMBZ5245BS-7-F and BZX384-C15, BZT52C15S-7 offers tighter automotive-grade reliability validation and optimized SOD323 footprint for space-constrained modules, though with lower power headroom than the SOT-23 alternative.

FAQ
What is the maximum reverse voltage before breakdown for BZT52C15S-7?
The BZT52C15S-7 has a nominal zener voltage of 15 V with a guaranteed range of 13.8 V to 15.6 V at 5 mA test current. Breakdown begins at the minimum specified value (13.8 V), and full regulation is established above this threshold under defined current conditions.
Is BZT52C15S-7 suitable for use in automotive applications?
Yes - BZT52C15S-7 is explicitly qualified to AEC-Q101 standards, including stress tests for temperature cycling, humidity, and high-temperature operating life. Its SOD323 package and lead-free construction meet automotive PCB assembly requirements.
How does the temperature coefficient affect regulation accuracy?
The +10.5 mV/°C temperature coefficient means the zener voltage increases by approximately 10.5 mV per degree Celsius rise above 25°C. For a 50°C ambient shift, this results in ~525 mV drift - a factor that must be compensated in high-precision references via circuit topology or calibration.
Can BZT52C15S-7 replace BZT52C12S-7 in a 12 V circuit?
No - BZT52C15S-7 has a 15 V nominal zener voltage versus 12 V for BZT52C12S-7. Substituting it would raise the regulation point by 3 V, potentially damaging downstream 12 V-rated components or causing functional failure in voltage-sensitive circuits.
