Product details
Overview
BZT52C6V2TQ-13-F from Diodes Incorporated is a surface-mount Zener diode with nominal 6.2 V zener voltage, 5 mA test current, 10 Ω maximum zener impedance at 1 kHz, 300 mW power dissipation, and SOD523 package-used for precision voltage regulation and overvoltage protection in low-power automotive and industrial sensor signal conditioning circuits.
For engineers reviewing the BZT52C6V2TQ-13-F datasheet, BZT52C6V2TQ-13-F pinout, BZT52C6V2TQ-13-F application, or BZT52C6V2TQ-13-F equivalent, this page delivers verified electrical specs, thermal behavior, cathode-band polarity confirmation, JEDEC-qualified reliability data, and direct AEC-Q101 context for automotive-grade deployment.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its 6.2 V nominal zener voltage exhibits +0.4 mV/°C temperature coefficient and ≤3.0 µA reverse leakage at 4.0 V, enabling accurate clamping in analog front-end protection networks.
The device is rated for -55°C to +150°C operating temperature, features 417°C/W junction-to-ambient thermal resistance on FR-4 PCB, and complies with JEDEC high-reliability standards-making it suitable for under-hood automotive modules where thermal stability and long-term parametric drift are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5234BT1G | 6.2 V nominal, 500 mW PD, SOD-123 package, 15 Ω ZZT | Larger footprint, higher power handling, but 50% higher zener impedance | Select when board space allows larger package and higher surge energy absorption is required |
| BZX584C6V2 | 6.2 V nominal, 300 mW PD, SOD-523 package, 15 Ω ZZT, ±5% tolerance | Same footprint, wider VZ tolerance (±5% vs. ±6.5%), no AEC-Q101 qualification | Choose for cost-sensitive industrial designs where automotive qualification is not mandated |
Compared with MMSZ5234BT1G and BZX584C6V2, BZT52C6V2TQ-13-F offers tighter zener impedance (10 Ω), AEC-Q101 qualification, and superior thermal performance in identical SOD523 packaging-making it optimal for safety-critical automotive signal conditioning where parametric consistency and long-term reliability are non-negotiable.

FAQ
What is the cathode identification method for BZT52C6V2TQ-13-F?
The cathode is identified by a visible black band on the SOD523 package body, aligned with the cathode terminal. This marking conforms to JEDEC standard polarity conventions and is verified in Diodes' package outline drawings and DS30502 Rev. 18-2 documentation.
Does BZT52C6V2TQ-13-F meet AEC-Q101 stress test requirements?
Yes-BZT52C6V2TQ-13-F is qualified to AEC-Q101 Rev. D, including HTGB, AC/DC life test, temperature cycling, and ESD HBM ≥2 kV. The "Q" suffix explicitly denotes automotive qualification, and full test reports are available through Diodes' automotive product portal.
Can this Zener diode be used in parallel for higher power dissipation?
No-Zener diodes exhibit negative temperature coefficients and mismatched breakdown voltages; paralleling causes current hogging and thermal runaway. For >300 mW needs, use a single higher-rated device or active regulation instead.
What is the maximum reverse voltage (VR) before significant leakage occurs?
At 4.0 V reverse bias, leakage is guaranteed ≤3.0 µA per DS30502. Above 4.0 V, leakage rises exponentially-by 10 µA at 4.5 V and ~100 µA near 6.0 V-so 4.0 V is the practical upper limit for low-leakage biasing applications.
