Product details
Overview
BZT52C6V2Q-7-F from Diodes Incorporated is an automotive-grade surface-mount Zener diode with a nominal zener voltage of 6.2 V, ±5% tolerance (5.8–6.6 V), 500 mW power dissipation at TL = +75°C, 10 Ω typical zener impedance at 5 mA, and qualified to AEC-Q101 for high-reliability automotive power rail regulation and overvoltage protection.
For engineers reviewing the BZT52C6V2Q-7-F datasheet, BZT52C6V2Q-7-F pinout, BZT52C6V2Q-7-F application, or BZT52C6V2Q-7-F equivalent, key selection criteria include zener voltage stability under 5 mA test current, low dynamic impedance for precision clamping, SOD123 package compatibility with automated assembly, and AEC-Q101 qualification for under-hood electronics.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals when biased above its specified zener voltage. It delivers regulated output under variable load conditions with 0.4 mV/°C temperature coefficient and 3.7 µA maximum reverse leakage at 4.0 V.
Designed for medium-current general-purpose regulation, it supports continuous operation from –65°C to +150°C ambient, with thermal resistance junction-to-lead of 150°C/W and junction-to-ambient of 338°C/W on FR-4 PCB with 1-inch copper pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal, 5.8–6.6 V range at 5 mA - defines precise clamping threshold for 5 V rail protection |
| Power Dissipation (PD) | 500 mW at TL = +75°C - enables sustained operation in hot under-hood environments |
| Zener Impedance (ZZT) | 10 Ω max at 5 mA - ensures minimal voltage deviation during transient current changes |
| Reverse Leakage (IR) | 3.7 µA max at VR = 4.0 V - guarantees low standby power loss in always-on circuits |
| Temperature Coefficient | +0.4 mV/°C - provides predictable, low-drift voltage reference over full operating range |
| Package | SOD123 - compact 2-pin surface-mount outline compatible with standard pick-and-place and reflow processes |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5234B-TP (Micro Commercial) | Same 6.2 V nominal, but ±5% tolerance, 500 mW rating, and SOD-123 package; no AEC-Q101 qualification | Not suitable for automotive under-hood use; acceptable for commercial-grade consumer power supplies | Select only for cost-sensitive non-automotive designs where qualification is not required |
| BZX84-C6V2 (Nexperia) | 6.2 V nominal, ±5%, 300 mW PD, SOT-23 package; AEC-Q101 qualified but lower power rating | Limited to lower-power signal-level clamping; unsuitable for >100 mA transient suppression | Prefer when board space is constrained and peak dissipation remains below 300 mW |
Compared with MMSZ5234B-TP and BZX84-C6V2, BZT52C6V2Q-7-F uniquely combines AEC-Q101 qualification, 500 mW power handling, and SOD-123 footprint-making it the only option for automotive 5 V rail clamping where both reliability and thermal margin are mandatory.

FAQ
What is the maximum reverse leakage current for BZT52C6V2Q-7-F at 4.0 V?
The maximum reverse leakage current is 3.7 µA at VR = 4.0 V and TA = +25°C, as specified in the Electrical Characteristics table. This value ensures minimal quiescent current draw in always-on monitoring circuits and contributes to system-level power budget accuracy.
Is BZT52C6V2Q-7-F compatible with lead-free reflow profiles?
Yes - the device features matte tin finish annealed over Alloy 42 leadframe and is fully RoHS-compliant. It meets MIL-STD-202, Method 208 for solderability and is rated for standard JEDEC J-STD-020 lead-free reflow profiles up to 260°C peak temperature.
How does the temperature coefficient affect regulation accuracy over –40°C to +125°C?
With a temperature coefficient of +0.4 mV/°C, the zener voltage drifts approximately ±62 mV across the full range - resulting in a total variation of ±1.0% relative to 6.2 V. This is verified in production testing and supports stable reference performance in automotive cabin and under-hood applications.
Can BZT52C6V2Q-7-F replace BZT52C6V2-7-F in existing designs?
Yes - the Q-suffix denotes AEC-Q101 qualification, while all electrical, thermal, and mechanical specifications (including zener voltage, impedance, package, and marking) are identical to the commercial BZT52C6V2-7-F. No layout or schematic changes are required for drop-in automotive upgrade.
