Product details
Overview
BZT52C6V8-13-F 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 - used for precision voltage regulation and overvoltage protection in low-power analog supply rails.
For engineers reviewing the BZT52C6V8-13-F datasheet, BZT52C6V8-13-F pinout, BZT52C6V8-13-F application, or BZT52C6V8-13-F equivalent, key selection criteria include zener voltage accuracy, dynamic impedance at operating current, thermal resistance (338 °C/W), power derating above +25°C ambient, and SOD123 package compatibility with automated PCB assembly.
Technical Context
This device operates as a two-terminal voltage reference using planar silicon junction technology, delivering stable breakdown behavior under reverse bias with minimal temperature drift (±0.4 mV/°C typical coefficient near 6.8 V). It supports continuous DC regulation and transient clamping without external biasing.
Designed for commercial-grade applications, it features a cathode-band polarity indicator, matte tin-plated alloy-42 leads, and UL 94V-0 molded plastic case - all compliant with AEC-Q101 reliability stress testing when qualified with 'Q' suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.8 V nominal, 6.4–7.2 V range at 5 mA - ensures ±5% regulation tolerance for 5 V–12 V rail stabilization |
| Power Dissipation (PD) | 370 mW at +25°C ambient - limits continuous current to ~54 mA at 6.8 V without heatsinking |
| Zener Impedance (ZZT) | 15 Ω max at 1 kHz, 5 mA - maintains tight voltage regulation under small-signal load variations |
| Reverse Current (IR) | 2.0 µA max at VR = 4.5 V - guarantees low leakage in standby or battery-backed circuits |
| Thermal Resistance (RθJA) | 338 °C/W on FR-4 with 1-inch copper pad - requires layout-aware thermal design for >100 mW operation |
| Operating Temperature | −65°C to +150°C - supports industrial and automotive under-hood environments when qualified |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage 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) | Preferred for ultra-dense layouts; requires tighter thermal management above 100 mW | Select when board space is constrained and power dissipation remains ≤100 mW |
| BZX84-C6V8 | 6.8 V nominal, SOT-23 package, 350 mW PD, 40 Ω ZZT - higher impedance and lower power rating | Suitable for signal-level clamping only; not recommended for active regulation loads >1 mA | Choose only for cost-sensitive, low-current biasing where 15 Ω impedance is non-critical |
Compared with MMBZ5235BS-7-F and BZX84-C6V8, BZT52C6V8-13-F offers superior thermal performance (338 °C/W vs. 400 °C/W), lower dynamic impedance (15 Ω vs. 40 Ω), and higher continuous power handling (370 mW vs. 250 mW), making it optimal for stable regulation in industrial and automotive power domains.

FAQ
What is the maximum continuous reverse current the BZT52C6V8-13-F can handle at 6.8 V?
The device is rated for 5 mA test current (IZT) and supports continuous operation up to its 370 mW power limit at +25°C ambient. At 6.8 V, this corresponds to ~54 mA maximum average current before exceeding thermal limits - derating required above +25°C per the 338 °C/W RθJA curve.
Does BZT52C6V8-13-F have AEC-Q101 qualification?
No - the '-13-F' suffix denotes commercial-grade qualification. The automotive-qualified version is BZT52C6V8Q-13-F, which undergoes additional stress testing per AEC-Q101 including HTGB, HTRB, and temperature cycling. Both share identical electrical specs and SOD123 packaging.
Can this Zener diode be used in series or parallel configurations?
Series connection is acceptable for higher-voltage references (e.g., two 6.8 V devices for ~13.6 V), but mismatched temperature coefficients may cause imbalance. Parallel use is not recommended due to unequal current sharing from parameter variation - active regulation or matched arrays are preferred for higher current.
What is the typical capacitance of BZT52C6V8-13-F at 1 MHz and 1 V reverse bias?
Based on Figure 5 in DS18004 Rev. 38, the typical total capacitance for 6.8 V nominal Zeners is approximately 45 pF at 1 MHz and 1 V reverse bias - a value confirmed across the C6V2 through C7V5 group in the datasheet's capacitance vs. voltage plot.
