Product details
Overview
BZV55-B6V8,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 6.66 V to 6.94 V nominal regulation at 5 mA, with ±2 % tolerance, 30 Ω typical differential resistance, and 4.5 pF capacitance at 1 MHz. It delivers stable reference voltage in power supply feedback loops, overvoltage protection circuits, and precision biasing networks for analog front-ends.
For engineers reviewing the BZV55-B6V8,115 datasheet, BZV55-B6V8,115 pinout, BZV55-B6V8,115 application, or BZV55-B6V8,115 equivalent, key selection criteria include its tight 2 % tolerance, low 30 Ω dynamic impedance, 200 mA maximum forward current, 400 mW total power dissipation at ≤50 °C ambient, and SOD80C thermal resistance of 300 K/W to solder point.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable DC reference voltage under varying load and temperature conditions. Its temperature coefficient of +1.2 mV/K at 5 mA enables predictable drift compensation in mid-voltage reference designs.
The device exhibits low 4.5 pF junction capacitance at 0 V reverse bias and 1 MHz, supporting stable performance in high-frequency feedback paths. Its non-repetitive peak reverse power dissipation is rated at 40 W for 100 µs square-wave pulses, enabling transient surge clamping in low-energy protection circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C6V8 | ±5 % tolerance, 50 Ω typical rdif, same SOD80C package | Higher voltage drift and looser regulation; suitable only for non-critical biasing | Select when cost sensitivity outweighs regulation accuracy requirements |
| MMSZ4687T1G | ±5 % tolerance, 40 Ω rdif, SOD-123 package, 500 mW Ptot | Larger footprint, higher thermal resistance (400 K/W), different solder profile | Choose only if SOD-123 is already standardized in layout and 500 mW rating is required |
Compared with BZV55-B6V8,115, BZX55C6V8 trades 2 % tolerance and 30 Ω impedance for lower unit cost, while MMSZ4687T1G offers higher power but sacrifices board space and thermal performance-making the BZV55-B6V8,115 optimal for space-constrained, accuracy-critical 6.8 V references.

FAQ
What is the maximum continuous reverse current this diode can sustain at 6.8 V?
The BZV55-B6V8,115 is rated for 5 mA nominal Zener test current, with a maximum continuous reverse current limited by its 400 mW power dissipation at ≤50 °C ambient. At 6.8 V, this corresponds to approximately 58.8 mA (400 mW ÷ 6.8 V), assuming no additional thermal derating beyond the specified ambient condition.
Does this part meet JEDEC JESD47 reliability standards for Zener diodes?
Yes-Nexperia qualifies the BZV55-B6V8,115 per JEDEC JESD47 stress testing requirements including HTOL (high-temperature operating life), TST (temperature cycling), and HAST (highly accelerated stress test), with data published in the official product reliability report (document number REL-BZV55).
Can this diode be used in parallel for higher current handling?
No-Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, causing current hogging when paralleled. The BZV55-B6V8,115 has +1.2 mV/K TC, so mismatched units will thermally diverge; parallel operation is not recommended without individual ballast resistors.
Is the SOD80C package lead-free and RoHS-compliant?
Yes-the BZV55-B6V8,115 uses lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH SVHC regulations, with full material declarations available in Nexperia's IPC-1752-compliant database.
