Product details
Overview
BZT52C13TQ-7-F from Diodes Incorporated is a surface-mount Zener diode with nominal 13 V zener voltage (12.4–14.1 V range), 5 mA test current, 30 Ω maximum zener impedance at 5 mA, 0.1 µA maximum reverse leakage at 11.0 V, and ±8.0 mV/°C temperature coefficient - used for precision voltage reference and overvoltage protection in low-power analog signal conditioning circuits.
For engineers reviewing the BZT52C13TQ-7-F datasheet, BZT52C13TQ-7-F pinout, BZT52C13TQ-7-F application, or BZT52C13TQ-7-F equivalent, this part serves as a stable, AEC-Q qualified automotive-grade voltage clamp in compact SOD523 packaging with JEDEC-compliant reliability, RoHS/Green compliance, and thermal resistance of 417 °C/W.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals under varying load and temperature conditions. Its 13 V nominal zener voltage is specified at 5 mA test current, with tight tolerance (±0.6 V) and low dynamic impedance (≤30 Ω) ensuring minimal voltage deviation during transient current changes.
The device features a negative temperature coefficient of −7.0 to +0.2 mV/°C (typical ±8.0 mV/°C), enabling predictable drift compensation in temperature-sensitive references. It is rated for 300 mW power dissipation at 25°C ambient and derates linearly above 25°C per the published curve (417 °C/W RθJA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.0 V nominal, 12.4–14.1 V range at IZT = 5 mA - defines clamping threshold for overvoltage protection and reference stability. |
| Zener Impedance (ZZT) | ≤30 Ω at 5 mA - ensures minimal output voltage variation under changing load current. |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 11.0 V - guarantees low standby power loss in high-impedance bias networks. |
| Power Dissipation (PD) | 300 mW at TA = 25°C - sets maximum continuous power handling on standard FR-4 PCB with 2 oz copper. |
| Temperature Coefficient | ±8.0 mV/°C - enables predictable voltage drift correction in temperature-compensated references. |
| Package | SOD523 - 1.25 mm × 0.85 mm footprint, 0.6 mm height, suitable for space-constrained PCB layouts. |
| RoHS / Green Compliance | Fully lead-free, halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) - meets global environmental regulations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5242BS-7-F | Same 13 V nominal zener, but SOT-323 package (2.2 mm × 1.35 mm); higher RθJA = 450 °C/W; 500 mW PD. | Larger footprint and higher thermal resistance - less suitable for ultra-dense layouts but supports higher peak power. | Select when board layout allows larger package and higher transient power handling is required. |
| BZX84-C13-7-F | 13 V zener in SOT-23; 350 mW PD; 35 Ω ZZT; 0.1 µA IR at 11 V; wider VZ tolerance (12.4–13.7 V). | Higher zener impedance and looser tolerance reduce reference accuracy in precision circuits. | Choose for cost-sensitive industrial designs where ±0.7 V tolerance and 35 Ω impedance are acceptable. |

FAQ
What is the maximum power dissipation for BZT52C13TQ-7-F at 85°C ambient?
At 85°C ambient, the device's power dissipation must be derated linearly from 300 mW at 25°C using the 417 °C/W thermal resistance. The allowable power is calculated as 300 mW × (1 − (85 − 25)/417) ≈ 214 mW. This ensures junction temperature remains within the −55°C to +150°C operating range.
Is BZT52C13TQ-7-F qualified for automotive applications?
Yes - the "Q" suffix denotes qualification to AEC-Q101 for discrete semiconductors. It is manufactured in IATF 16949-certified facilities, supports PPAP documentation, and meets JEDEC reliability standards referenced in AEC-Q testing protocols.
How is polarity identified on the SOD523 package?
Polarity is marked by a visible cathode band near one end of the SOD523 package. When viewed from the top with the band on the left, the left terminal is the cathode and the right terminal is the anode - consistent with standard diode marking conventions.
What is the typical capacitance of BZT52C13TQ-7-F at 1 MHz and 1 V reverse bias?
Based on Figure 4 in the datasheet, the typical total capacitance for a 13 V Zener (BZT52C13T) is approximately 15 pF at 1 MHz and 1 V reverse bias. This value supports use in low-frequency voltage reference and protection circuits without introducing significant signal coupling.
