Product details
Overview
BZT52C6V8LP-7 from Diodes Incorporated is a surface-mount Zener diode with a nominal zener voltage of 6.8 V, ±5% tolerance (6.4–7.2 V), 250 mW power dissipation, 15 Ω zener impedance at 5 mA, and AEC-Q101 qualification for automotive-grade reliability. It operates from −65 °C to +150 °C and is used for precision voltage regulation in low-power sensor biasing circuits.
For engineers reviewing the BZT52C6V8LP-7 datasheet, BZT52C6V8LP-7 pinout, BZT52C6V8LP-7 application, or BZT52C6V8LP-7 equivalent, key selection criteria include zener voltage accuracy, low dynamic impedance, thermal stability, RoHS-compliant DFN1006-2 packaging, and AEC-Q101 qualification for automotive electronics.
Technical Context
This device functions as a two-terminal voltage reference diode operating in reverse breakdown mode. Its 6.8 V nominal zener voltage is specified at 5 mA test current, with temperature coefficient of +1.2 mV/°C and maximum reverse leakage of 2 µA at 4.5 V.
The DFN1006-2 package features NiPdAu-plated terminals, J-STD-020C Level 1 moisture sensitivity, and UL 94V-0 mold compound. Thermal resistance is 500 °C/W (junction-to-ambient) on FR-4 PCB with recommended pad layout.
Key Specifications

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 |
|---|---|---|---|
| MMSZ4687-7-F | 6.8 V, ±5%, 500 mW, SOD-123 package, 30 Ω ZZT, no AEC-Q101 | Larger footprint, higher thermal resistance (625 °C/W), unsuitable for space-constrained automotive modules | Select when higher power margin is needed and AEC-Q101 is not required |
| BZX384-C6V8,115 | 6.8 V, ±5%, 300 mW, SOT-23 package, 40 Ω ZZT, AEC-Q101 qualified | 3-pin SOT-23 requires unused pin routing; larger area (2.9 × 1.3 mm) vs. DFN1006-2 (1.0 × 0.6 mm) | Select when legacy SOT-23 layout compatibility is prioritized over miniaturization |
Compared with MMSZ4687-7-F and BZX384-C6V8,115, BZT52C6V8LP-7 offers the smallest footprint, lowest zener impedance, and AEC-Q101 qualification in a 1.0 × 0.6 mm package-making it optimal for next-generation automotive and portable industrial sensors where board space and regulation precision are critical.

FAQ
What is the maximum reverse leakage current for BZT52C6V8LP-7 at 4.5 V?
The maximum reverse leakage current (IR) is 2 µA at VR = 4.5 V and TA = 25 °C, as specified in the Electrical Characteristics table. This value remains ≤5 µA across the full operating temperature range (−65 °C to +150 °C), ensuring low standby power in always-on sensor bias networks.
Is BZT52C6V8LP-7 compatible with lead-free reflow profiles?
Yes. The device uses NiPdAu-plated terminals and is rated for soldering per MIL-STD-202, Method 208. Its DFN1006-2 package supports standard JEDEC J-STD-020C Level 1 reflow profiles, including peak temperatures up to 260 °C for ≤30 seconds, with no pre-bake required.
How does the +1.2 mV/°C temperature coefficient affect regulation accuracy?
The +1.2 mV/°C coefficient means VZ increases by 1.2 mV per degree Celsius rise in junction temperature. Over a 100 °C span (e.g., −40 °C to +60 °C), this results in ~120 mV total drift - approximately ±1.8% of 6.8 V - which is acceptable for non-critical biasing but requires compensation in metrology-grade references.
Can BZT52C6V8LP-7 be used in place of through-hole 1N4734A?
No. While both are 6.8 V Zeners, the 1N4734A has 1 W power rating, TO-92 package, and 5 Ω ZZT, whereas BZT52C6V8LP-7 is rated for 250 mW in DFN1006-2 with 15 Ω ZZT. Substitution is only valid in low-power, surface-mount designs where thermal and space constraints prohibit through-hole components.
