Product details
Overview
BZT52C6V2S-7 from Diodes Incorporated is a surface-mount Zener diode with nominal 6.2 V zener voltage (5.8–6.6 V range), 5 mA test current, 10 Ω maximum zener impedance at 1 kHz, 4.0 V reverse voltage rating at 2 µA leakage, and ±0.4 mV/°C temperature coefficient - used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZT52C6V2S-7 datasheet, BZT52C6V2S-7 pinout, BZT52C6V2S-7 application, or BZT52C6V2S-7 equivalent, key selection criteria include zener voltage tolerance, dynamic impedance at operating current, thermal resistance (625 °C/W), SOD323 package compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown when cathode-to-anode voltage exceeds its specified zener threshold. It delivers stable regulation under 5 mA test current with low dynamic impedance (10 Ω) and minimal voltage drift (±0.4 mV/°C).
Designed for surface-mount assembly on FR-4 PCBs using recommended pad layout, it supports automated placement and reflow soldering. Its SOD323 package provides compact footprint (1.30 × 1.70 mm), 0.0049 g mass, and UL 94V-0 flammability rating - optimized for space-constrained consumer and automotive electronics.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | Zener voltage 6.2 V (same nominal), but 15 Ω ZZT, higher 500 mW PD, SOT-23 package | Larger footprint; suited for higher-power dissipation where board space permits | Select when thermal margin >200 mW is required and SOT-23 is acceptable in layout |
| BZX84-C6V2 | 6.2 V nominal, 20 Ω ZZT, 350 mW PD, SOT-23 package, no AEC-Q101 qualification | Non-automotive grade; lacks automotive reliability validation and tighter tempco | Acceptable for cost-sensitive commercial designs where AEC-Q101 is not mandated |

FAQ
What is the maximum reverse leakage current for BZT52C6V2S-7 at 4.0 V?
The maximum reverse leakage current (IR) is 2 µA at VR = 4.0 V and TA = 25°C. This value is confirmed in the Electrical Characteristics table of DS30093 Rev. 20-2 and reflects the device's ability to maintain high impedance below breakdown, critical for low-power bias networks and precision reference dividers.
Is BZT52C6V2S-7 qualified for automotive applications?
Yes, BZT52C6V2S-7 is qualified to AEC-Q101 standards for high-reliability automotive use. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and accelerated life - validating suitability for engine control units, body electronics, and ADAS subsystems per Diodes Incorporated's documentation.
What is the thermal resistance (RθJA) of BZT52C6V2S-7, and how is it measured?
RθJA is 625 °C/W, measured with the device mounted on an FR-4 PCB using Diodes Incorporated's recommended pad layout (per package outline document). This value assumes natural convection cooling and defines junction-to-ambient temperature rise per unit power dissipated - essential for thermal design in enclosed or high-ambient environments.
Does BZT52C6V2S-7 have halogen-free and antimony-free construction?
Yes, BZT52C6V2S-7 is a "Green" device meeting Diodes Incorporated's halogen- and antimony-free definition: <900 ppm bromine, <900 ppm chlorine (total Br+Cl <1500 ppm), and <1000 ppm antimony compounds. This is verified for all units manufactured with Date Code V9 (week 33, 2008) and newer.
