Product details
Overview
BZT52C15SQ-7-F from Diodes Incorporated is a surface-mount Zener diode with a nominal zener voltage of 15 V (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, overvoltage protection, and reference applications for automotive and industrial control circuits.
For engineers reviewing the BZT52C15SQ-7-F datasheet, BZT52C15SQ-7-F pinout, BZT52C15SQ-7-F application, or BZT52C15SQ-7-F equivalent, key selection criteria include zener voltage tolerance, dynamic impedance at test current, temperature coefficient, reverse leakage at rated voltage, and AEC-Q101 qualification status.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in silicon PN junction. Its 15 V nominal zener voltage is stabilized by planar die construction and calibrated during production to meet ±5% tolerance at IZT = 5 mA.
Thermal resistance is 625 °C/W (junction-to-ambient, FR-4 board), and it exhibits a positive temperature coefficient of +10.5 mV/°C - enabling predictable drift compensation in temperature-sensitive references.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5245B-7-F | Zener voltage 15 V (14.25–15.75 V), 500 mW PD, SOD-123 package | Higher power rating but larger footprint; not AEC-Q101 qualified | Select when thermal margin >200 mW is required and automotive qualification is unnecessary |
| BZX84-C15 | Zener voltage 15 V (14.3–15.7 V), 300 mW PD, SOT-23 package | Three-pin SOT-23 requires orientation-aware placement; no AEC-Q101 validation | Choose for legacy designs using SOT-23 land patterns where AEC-Q101 is not mandated |

FAQ
What is the maximum reverse leakage current for BZT52C15SQ-7-F at 13.0 V?
The maximum reverse leakage current is 0.1 µA at VR = 13.0 V and TA = +25°C, as specified in the Electrical Characteristics table. This ultra-low leakage ensures minimal loading in high-impedance reference circuits and preserves accuracy in battery-powered sensor nodes.
Is BZT52C15SQ-7-F suitable for use in automotive applications?
Yes - BZT52C15SQ-7-F is explicitly qualified to AEC-Q101 standards, including stress tests for temperature cycling, humidity, and mechanical shock. Its SOD323 package and green material composition meet automotive ELV and RoHS 2 requirements for under-hood and cabin electronics.
How does the +10.5 mV/°C temperature coefficient affect circuit design?
The positive temperature coefficient means VZ increases linearly with junction temperature. In precision references, this drift can be compensated via resistor networks or digital calibration - e.g., a 50°C rise causes ~0.525 V increase, which is predictable and correctable in metrology-grade systems.
What is the recommended pad layout for SOD323 mounting?
Diodes Incorporated specifies a pad layout with X = 0.590 mm, Y = 0.450 mm, X1 = 2.700 mm, and thermal relief for the cathode pad. Full dimensions and copper pour guidelines are published in Package Outline Document #AP02004 at diodes.com/package-outlines.html.
