Product details
Overview
BZT52C6V2-7-F from Diodes Incorporated is a surface-mount 6.2 V Zener diode in SOD123 package, rated for 500 mW power dissipation at TL = +75°C and 370 mW at TA = +25°C, with 10 Ω typical zener impedance at 5 mA test current and ±5% voltage tolerance (5.8–6.6 V), used for precision voltage regulation and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZT52C6V2-7-F datasheet, BZT52C6V2-7-F pinout, BZT52C6V2-7-F application, or BZT52C6V2-7-F equivalent, key selection criteria include zener voltage accuracy, thermal resistance (RθJA = 338 °C/W), reverse leakage (3.7 µA @ 4.0 V), temperature coefficient (+0.4 mV/°C), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its planar die construction ensures consistent breakdown characteristics, while the SOD123 package supports automated assembly and delivers RθJL = 150 °C/W for effective thermal management in compact PCB layouts.
The device exhibits low dynamic impedance (10 Ω @ 5 mA) and tight voltage tolerance (±5%), enabling accurate clamping in voltage-monitoring circuits. Its temperature coefficient of +0.4 mV/°C indicates slight positive drift, requiring compensation only in high-precision references above 85°C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | Same 6.2 V nominal, but SOT-323 package (smaller footprint, RθJA = 390 °C/W), 200 mW rating at TA = +25°C | Preferred for ultra-dense portable designs where board space is constrained and power <200 mW | Select when PCB real estate is limited and thermal budget permits higher junction rise |
| BZX84-C6V2 | 6.2 V Zener in SOT-23 package, 350 mW rating, 30 Ω ZZT @ 5 mA, no AEC-Q101 qualification | Suitable for commercial-grade consumer electronics without automotive reliability requirements | Choose for cost-sensitive non-automotive applications where ±5% tolerance and basic regulation suffice |
Compared with MMBZ5234BS-7-F and BZX84-C6V2, BZT52C6V2-7-F offers superior power handling (370 mW), lower impedance (10 Ω), and AEC-Q101 qualification-making it optimal for automotive and industrial systems demanding robustness, stability, and thermal margin.

FAQ
What is the maximum reverse voltage (VR) this Zener diode can withstand before breakdown?
The BZT52C6V2-7-F has a nominal Zener voltage of 6.2 V with a guaranteed range of 5.8–6.6 V at 5 mA test current. It begins controlled reverse breakdown at approximately 5.8 V and maintains regulation up to its power limit. The absolute maximum reverse voltage is not specified separately-it is defined by the Zener characteristic itself, and operation beyond 6.6 V at rated current risks exceeding thermal limits.
Is this part suitable for use in automotive applications?
Yes-BZT52C6V2-7-F is qualified to AEC-Q101 standards, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its SOD123 package, halogen-free construction, and operating temperature range of –65°C to +150°C meet automotive environmental and reliability requirements.
How does the temperature coefficient affect voltage regulation accuracy?
The BZT52C6V2-7-F has a temperature coefficient of +0.4 mV/°C, meaning its Zener voltage increases by 0.4 mV per degree Celsius rise in junction temperature. Over a 100°C range (–40°C to +60°C ambient, assuming ~30°C rise), this results in ~40 mV total drift-within its ±5% (±310 mV) tolerance band, making it appropriate for moderate-precision regulation tasks.
Can this Zener diode be used in parallel for higher power handling?
No-Zener diodes should not be paralleled due to mismatched breakdown voltages causing current hogging and thermal runaway. For higher power, use a single higher-rated Zener (e.g., 1 W axial part) or implement active regulation with a transistor-based shunt. The BZT52C6V2-7-F's 370 mW rating is intended for individual use with proper PCB copper area for heat dissipation.
