Product details
Overview
BZX84C6V8W-7-F from Diodes Incorporated is a 6.8 V, 200 mW surface-mount Zener diode in SOT-323 package, rated for 5 mA test current with 15 Ω dynamic impedance and ±0.4 to +4.5 mV/°C temperature coefficient, used for precision voltage regulation and reference in low-power analog circuits.
For engineers reviewing the BZX84C6V8W-7-F datasheet, BZX84C6V8W-7-F pinout, BZX84C6V8W-7-F application, or BZX84C6V8W-7-F equivalent, key selection criteria include zener voltage tolerance (6.4–7.2 V), low reverse leakage (≤2.0 µA at 4.0 V), thermal resistance (625 K/W), and RoHS-compliant green molding compound suitability for space-constrained PCB designs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across load variations, with nominal regulation at 5 mA test current and specified dynamic impedance measured at 1 kHz. Its planar die construction ensures repeatable breakdown characteristics and low noise performance.
The device exhibits a positive temperature coefficient (+1.2 to +4.5 mV/°C) above 6 V, enabling predictable drift compensation in temperature-sensitive references. It is rated for operation from –65 °C to +125 °C and derates linearly above 25 °C ambient per the published power derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.8 V nominal, 6.4–7.2 V min/max at IZT = 5 mA - defines regulation setpoint tolerance |
| Power Dissipation (PD) | 200 mW at TA = 25 °C - limits continuous DC or pulsed power in compact layouts |
| Zener Impedance (ZZT) | 15 Ω max at IZT = 5 mA, f = 1 kHz - determines output voltage stability under load transients |
| Reverse Leakage (IR) | ≤2.0 µA at VR = 4.0 V - ensures minimal quiescent current in standby bias networks |
| Temp Coefficient (αVZ) | +1.2 to +4.5 mV/°C at IZT = 5 mA - enables thermal drift modeling in precision references |
| Package | SOT-323 - 2.2 mm × 1.35 mm footprint with 0.65 mm lead pitch for high-density routing |
| Operating Temp | –65 °C to +125 °C - supports industrial and automotive under-hood environments |

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 | Zener voltage 6.8 V (same nominal), but 350 mW PD, 30 Ω ZZT, SOT-323 package | Higher power handling; less precise regulation due to higher ZZT | Select when higher surge energy absorption is required and tighter voltage stability is secondary |
| 1SMA5919BT3G | 6.8 V nominal, 1.5 W PD, DO-214AC package, 10 Ω ZZT, larger footprint | Higher power and lower impedance, but incompatible SMT footprint and thermal mass | Select for board-level transient suppression where space allows and 200 mW is insufficient |
Compared with MMBZ5235BS-7-F and 1SMA5919BT3G, BZX84C6V8W-7-F offers optimal balance of precision (15 Ω ZZT), compactness (SOT-323), and low-leakage regulation for space-constrained, low-power analog subsystems.

FAQ
What is the maximum reverse leakage current for BZX84C6V8W-7-F at 4.0 V?
The maximum reverse leakage current is 2.0 µA at VR = 4.0 V and TA = 25 °C, as specified in the Electrical Characteristics table. This value remains ≤5.0 µA across the full operating temperature range (–65 °C to +125 °C), verified per test conditions in DS30066 Rev. 15-2.
Is BZX84C6V8W-7-F compatible with lead-free reflow profiles?
Yes - it features matte tin-plated alloy 42 leads and complies with J-STD-020D Level 1 moisture sensitivity, supporting standard Pb-free reflow up to 260 °C peak. The "Green" molding compound is halogen-free and UL 94V-0 rated, eliminating concerns about corrosive residues or flame-retardant outgassing.
Does this Zener diode have a specified capacitance value?
No specific capacitance is listed in the datasheet for BZX84C6V8W-7-F. However, Figure 4 shows typical total capacitance for 6.8 V devices is <5 pF at VR = 1 V, making it suitable for high-frequency clamping and low-noise reference applications where parasitic capacitance must be minimized.
Can BZX84C6V8W-7-F replace BZX84C6V2W in a 6.2 V circuit?
No - its nominal zener voltage is 6.8 V (min 6.4 V, max 7.2 V), which exceeds the 6.2 V (min 5.8 V, max 6.6 V) range of BZX84C6V2W. Substituting would raise regulated voltage by ~0.6 V, potentially violating downstream IC input tolerances or bias point requirements unless circuit recalibration is performed.
