Product details
Overview
BZT52C6V8-7 from Diodes Incorporated is a surface-mount Zener diode with nominal 6.8 V zener voltage, 5 mA test current, 15 Ω maximum zener impedance at 1 kHz, 2.0 mA maximum reverse current at 4.5 V, and ±5% voltage tolerance. It delivers precise voltage regulation in low-power analog reference and overvoltage protection circuits for industrial sensor interfaces and power supply feedback loops.
For engineers reviewing the BZT52C6V8-7 datasheet, BZT52C6V8-7 pinout, BZT52C6V8-7 application, or BZT52C6V8-7 equivalent, key selection criteria include zener voltage accuracy (6.4–7.2 V), thermal resistance (338 °C/W), SOD123 package compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and temperature conditions. Its planar die construction ensures consistent breakdown characteristics, while the 500 mW power dissipation rating (at TL = +75°C) supports sustained regulation in compact PCB layouts.
The device exhibits a positive temperature coefficient of +1.2 mV/°C near 6.8 V, enabling predictable drift compensation in temperature-sensitive references. Its 80 Ω maximum zener impedance at IZK = 2.0 mA confirms low dynamic resistance for high-precision clamping and voltage referencing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5235BS-7-F | Same 6.8 V nominal, but SOT-323 package (smaller footprint, higher RθJA = 400 °C/W) | Limited to lower-power (<250 mW) applications due to thermal constraints | Choose when board space is critical and power dissipation remains below 200 mW |
| BZX84-C6V8 | 6.8 V nominal, 350 mW PD, SOT-23 package, no AEC-Q101 qualification | Suitable for commercial-grade consumer products only | Prefer for cost-sensitive non-automotive designs where automotive reliability is not required |
Compared with MMBZ5235BS-7-F and BZX84-C6V8, BZT52C6V8-7 offers superior thermal performance (338 °C/W), AEC-Q101 qualification, and 370 mW usable power at +25°C-making it the optimal choice for automotive and industrial applications demanding long-term stability and high-reliability operation.

FAQ
What is the maximum reverse voltage (VR) at which BZT52C6V8-7 guarantees IR ≤ 2.0 µA?
The datasheet specifies that BZT52C6V8-7 maintains reverse current ≤ 2.0 µA at VR = 4.5 V. This value is measured under standard conditions (TA = +25°C) and defines the upper limit of safe non-breakdown operation before entering the zener region.
Does BZT52C6V8-7 support reflow soldering per IPC-J-STD-020?
Yes - BZT52C6V8-7 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be subjected to unlimited floor life and standard Pb-free reflow profiles (peak temperature up to 260°C) without baking preconditioning.
How does the +1.2 mV/°C temperature coefficient affect voltage regulation accuracy over temperature?
With a +1.2 mV/°C coefficient, the zener voltage increases by approximately 120 mV over a 100°C range (−40°C to +60°C). For applications requiring tighter regulation, this drift must be compensated via circuit design or paired with negative-TC components.
Can BZT52C6V8-7 replace BZT52C6V2 in a 6.2 V reference circuit?
No - BZT52C6V8-7 has a nominal 6.8 V zener voltage (6.4–7.2 V range), while BZT52C6V2 is specified at 6.2 V (5.8–6.6 V). Substitution would shift the regulated voltage by ~0.6 V, potentially violating system-level voltage tolerances and causing functional failure.
