Product details
Overview
BZT52C15S-7-F from Diodes Incorporated is a surface-mount Zener diode with nominal 15 V zener voltage (13.8–15.6 V range), 5 mA test current, 30 Ω maximum zener impedance at 5 mA, 0.1 µA maximum reverse leakage at 13.0 V, and ±10.5 mV/°C temperature coefficient. It operates in SOD323 package for voltage regulation and reference in low-power analog circuits.
For engineers reviewing the BZT52C15S-7-F datasheet, BZT52C15S-7-F pinout, BZT52C15S-7-F application, or BZT52C15S-7-F equivalent, key selection criteria include zener voltage tolerance, dynamic impedance, thermal coefficient, reverse leakage at rated VR, and SOD323 footprint compatibility with automated assembly.
Technical Context
This Zener diode uses planar die construction to ensure stable breakdown characteristics and low noise performance under regulated bias. Its 200 mW power dissipation rating and 625 °C/W junction-to-ambient thermal resistance are defined for FR-4 PCB mounting with recommended pad layout.
The device exhibits a typical total capacitance of ~15 pF at 1 V reverse bias and demonstrates monotonic voltage-temperature behavior across –65 °C to +150 °C operating range, supporting precision reference use in industrial sensor signal conditioning and power supply feedback paths.

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 | Same SOD323 package; 15 V nominal but wider 14.25–15.75 V tolerance and 35 Ω ZZT | Higher VZ scatter reduces reference accuracy in precision circuits | Select when cost sensitivity outweighs ±0.3 V regulation tolerance requirements |
| BZX384-C15,115 | SOD323 package; 15 V nominal with 14.3–15.7 V range, 30 Ω ZZT, but only AEC-Q200 rated (not AEC-Q101) | Lacks automotive-grade reliability validation for safety-critical modules | Prefer for industrial consumer designs where AEC-Q101 is not mandated |
Compared with MMBZ5245BS-7-F and BZX384-C15,115, BZT52C15S-7-F offers tighter zener voltage tolerance (±0.9 V vs ±1.25 V), AEC-Q101 qualification, and identical dynamic impedance - making it optimal for automotive and high-reliability industrial references.

FAQ
What is the maximum power dissipation for BZT52C15S-7-F at 70°C ambient?
At 70°C ambient, the device's derated power dissipation is 120 mW, calculated using the 625 °C/W thermal resistance and linear derating curve from the datasheet. This assumes mounting on FR-4 with Diodes' recommended pad layout; exceeding this value risks thermal runaway and parametric shift.
Does BZT52C15S-7-F have a specified capacitance value?
Yes - the typical total capacitance is 15 pF at 1 V reverse bias and 25 °C, as shown in Figure 4 of the datasheet. Capacitance decreases with increasing reverse voltage and rises slightly with temperature, remaining below 20 pF across its operational range.
Is the cathode band polarity consistent across all SOD323-packaged Zeners from Diodes Incorporated?
Yes - all SOD323 Zener diodes in the BZT52C series, including BZT52C15S-7-F, use a single black cathode band adjacent to the cathode terminal. The top-view marking code (WJ for this part) appears opposite the band, confirming orientation per the mechanical drawing.
Can BZT52C15S-7-F be used in place of a 1N4744A in a through-hole design?
No - BZT52C15S-7-F is a surface-mount SOD323 device with different thermal and electrical characteristics than the axial-lead 1N4744A (1 W, DO-41). While both regulate near 15 V, the BZT52C15S-7-F has lower power rating (200 mW), higher ZZT, and requires PCB redesign for SMT placement and reflow.
