Product details
Overview
BZT52C15-13-F from Diodes Incorporated is a surface-mount 15 V Zener diode in SOD123 package, rated for 500 mW power dissipation at TL = +75°C and 370 mW at TA = +25°C, with 30 Ω maximum Zener impedance at 5 mA test current and ±5% voltage tolerance (13.8–15.6 V). It serves as a precision voltage reference or overvoltage clamp in low-power DC supply rails and signal conditioning circuits.
For engineers reviewing the BZT52C15-13-F datasheet, BZT52C15-13-F pinout, BZT52C15-13-F application, or BZT52C15-13-F equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJA = 338 °C/W), reverse leakage (<0.1 µA at 10.5 V), temperature coefficient (+9.2 to +13.0 mV/°C), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled knee characteristics, enabling stable regulation across 1–5 mA nominal current range. Its planar die construction ensures consistent voltage distribution and low dynamic impedance under transient load conditions.
The device exhibits a positive temperature coefficient (+9.2 to +13.0 mV/°C) above 5 V, supporting predictable drift compensation in temperature-sensitive references. Its SOD123 package provides low thermal resistance to lead (RθJL = 150 °C/W) and meets J-STD-020 Level 1 moisture sensitivity for standard reflow compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V nominal, 13.8–15.6 V range at 5 mA - defines regulated output voltage with ±5% tolerance for stable reference design |
| Power Dissipation | 370 mW at TA = +25°C - sets maximum continuous DC power handling on standard FR-4 PCB |
| Zener Impedance (ZZT) | ≤30 Ω at IZT = 5 mA - ensures minimal output voltage variation under small-signal current changes |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 10.5 V - guarantees negligible quiescent current in standby clamp applications |
| Temperature Coefficient | +9.2 to +13.0 mV/°C - quantifies voltage drift per degree Celsius for thermal error budgeting |

Pinout & Package
Two-terminal device in SOD123 package: anode and cathode marked by single band on cathode end. No internal pins; terminals are solderable matte tin-plated alloy 42 leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener reference ground node | Connected to lower-potential side of regulated circuit; forms return path during reverse bias operation |
| Cathode | Zener breakdown terminal / regulated output node | Connected to higher-potential side; voltage at this terminal clamps to 15 V when reverse biased above breakdown threshold |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5245B-7-F | Zener voltage 15 V, but rated 350 mW at TA = +25°C and uses SOT-23 package with higher RθJA (400 °C/W) | Limited thermal margin in high-density layouts; not AEC-Q101 qualified | Select when board space is constrained and automotive qualification is unnecessary |
| BZX84-C15-7-F | Same 15 V rating and SOT-23 package, but only commercial-grade (non-AEC-Q101) and higher ZZT (40 Ω) | Higher impedance reduces regulation stability under varying load; unsuitable for precision references | Prefer for cost-sensitive consumer applications where ±5% tolerance and basic clamping suffice |
Compared with MMBZ5245B-7-F and BZX84-C15-7-F, BZT52C15-13-F delivers superior thermal performance (338 °C/W vs. ≥400 °C/W), AEC-Q101 validation for automotive use, and tighter Zener impedance (30 Ω), making it optimal for mission-critical voltage reference and clamp roles in industrial and vehicle systems.

FAQ
What is the maximum reverse voltage (VR) at which BZT52C15-13-F guarantees IR ≤ 0.1 µA?
The datasheet specifies IR ≤ 0.1 µA at VR = 10.5 V, which is 70% of the nominal Zener voltage (15 V). This value defines the upper limit of the pre-breakdown region where leakage remains negligible-critical for low-power standby circuits and high-impedance reference nodes.
Can BZT52C15-13-F be used in place of a 12 V Zener diode for overvoltage protection?
No-it is not a drop-in replacement for 12 V Zeners due to its fixed 15 V breakdown voltage. Using it in a 12 V system would result in insufficient clamping action until voltage exceeds 13.8 V, risking damage to downstream 12 V-rated components before regulation engages.
Does the "-13-F" suffix indicate automotive qualification?
No-the "-13-F" denotes commercial-grade packaging: 10,000 units per tape-and-reel with lead-free, halogen-free finish. Automotive qualification requires the "Q" prefix (e.g., BZT52C15Q-13-F); this part is AEC-Q101 qualified but the suffix alone does not encode qualification status.
How does the SOD123 package affect thermal performance compared to DO-35 or SOT-23?
SOD123 offers lower RθJA (338 °C/W) than SOT-23 (≥400 °C/W) due to larger copper pad area and shorter thermal path, but higher than DO-35 (≈200 °C/W) because of smaller metal mass. Its 370 mW rating at +25°C reflects this mid-tier thermal capability-ideal for moderate-power regulation without heatsinking.
