Product details
Overview
BZT52C24-13-F from Diodes Incorporated is a surface-mount 24 V Zener diode in SOD123 package, rated for 500 mW power dissipation at TL = +75°C and 370 mW at TA = +25°C, with ±5% zener voltage tolerance (22.8–25.6 V), 70 Ω maximum zener impedance at 5 mA, and 0.1 µA maximum reverse leakage at 18.4 V. It serves as a precision voltage reference or overvoltage clamp in low-power analog and power supply regulation circuits.
For engineers reviewing the BZT52C24-13-F datasheet, BZT52C24-13-F pinout, BZT52C24-13-F application, or BZT52C24-13-F equivalent, key selection criteria include zener voltage accuracy, thermal resistance (RθJA = 338 °C/W), junction-to-lead thermal performance (RθJL = 150 °C/W), AEC-Q101 qualification status, and SOD123 footprint compatibility with automated assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under controlled current conditions. Its planar die construction ensures consistent breakdown characteristics, while the SOD123 package supports high-reliability mounting on FR-4 PCBs with defined copper pad layout per JEDEC standards.
The device exhibits a positive temperature coefficient of +16.8 mV/°C near 24 V, enabling predictable drift compensation in temperature-sensitive references. It is specified for operation from –65 °C to +150 °C and qualified to AEC-Q101 for automotive-grade reliability, with halogen- and antimony-free "Green" molding compound.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5249BS-7-F | Same 24 V nominal rating but SOT-323 package (smaller footprint); 200 mW PD at TA = +25°C | Limited to lower-power signal-level clamping; unsuitable for >10 mA continuous regulation | Select when board space is constrained and thermal budget permits reduced power handling |
| 1N4749A | Through-hole DO-41 package; 1 W PD; wider VZ tolerance (±5% same), but higher ZZT (20 Ω vs. 70 Ω) | Requires manual soldering or wave soldering; better suited for prototyping or legacy designs | Choose for high-current clamping (>20 mA) where thermal mass and mechanical robustness outweigh SMT advantages |
Compared with MMBZ5249BS-7-F and 1N4749A, BZT52C24-13-F offers optimal balance of SMT manufacturability, AEC-Q101 qualification, and 370 mW regulation capability in a widely adopted SOD123 footprint-making it preferred for volume automotive and industrial control applications.

FAQ
What is the maximum reverse current specification for BZT52C24-13-F at 18.4 V?
The maximum reverse leakage current is 0.1 µA at VR = 18.4 V and TA = +25°C, as specified in the Electrical Characteristics table. This low leakage ensures minimal power loss in high-impedance bias networks and preserves accuracy in precision reference applications.
Is BZT52C24-13-F suitable for automotive applications?
Yes - it is explicitly qualified to AEC-Q101 standards, confirming reliability under automotive temperature cycling, humidity, and mechanical stress tests. Its SOD123 package and "Green" material composition meet automotive manufacturing and environmental requirements.
How does the thermal resistance RθJA = 338 °C/W affect design margins?
This value means the junction temperature rises 338 °C per watt dissipated when mounted on an FR-4 PCB with 1-inch² copper pad. At 370 mW ambient-rated power, junction temperature rise is ~125 °C - requiring careful derating above +25°C ambient to stay within the –65 °C to +150 °C operating range.
What is the meaning of the "-13-F" suffix in the part number?
The "-13-F" denotes commercial-grade packaging: 10,000 units per tape-and-reel, with "F" indicating RoHS-compliant, lead-free plating. The "-7-F" variant would be identical except for 3,000-unit reels; "Q-13-F" indicates the automotive-qualified version with additional screening.
