Product details
Overview
BZV55-B68,115 from Nexperia is a 68 V ±2 % tolerance silicon Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 500 mW total power dissipation and 40 W non-repetitive peak reverse power, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZV55-B68,115 datasheet, BZV55-B68,115 pinout, BZV55-B68,115 application, or BZV55-B68,115 equivalent, this part serves as a stable shunt reference in power supply feedback loops, sensor biasing networks, and ESD-protected signal conditioning stages where tight voltage tolerance and low thermal drift are required.
Technical Context
This Zener diode operates in reverse breakdown with a nominal working voltage of 66.6 V to 69.4 V at IZ = 2 mA, exhibiting a temperature coefficient of +90 mV/K (typical) and differential resistance of 150 Ω (max) at IZ = 2 mA - enabling predictable regulation across industrial temperature ranges.
Its SOD80C package delivers low thermal resistance (Rth(j-sp) = 300 K/W), supports reflow and wave soldering per JEDEC standards, and maintains stable capacitance (71.7 pF typical at 1 MHz, VR = 0 V) for minimal AC loading in reference paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 68 V (66.6 V min / 69.4 V max at IZ = 2 mA); defines precise shunt regulation point |
| Tolerance | ±2 % (B-series); enables tighter output voltage control vs. ±5 % C-series alternatives |
| Total Power Dissipation | 500 mW (Tamb ≤ 50 °C on ceramic substrate); sets maximum continuous DC power handling |
| Non-repetitive Peak Reverse Power | 40 W (tp = 100 µs square wave); supports transient surge suppression without failure |
| Differential Resistance | 150 Ω max (at IZ = 2 mA); determines regulation stiffness and load-induced voltage deviation |
| Temperature Coefficient | +90 mV/K typical (at IZ = 2 mA); quantifies voltage drift per degree Celsius rise in junction temperature |
| Reverse Leakage Current | 250 nA max (at VR = 0.7 × VZ(nom) = 47.6 V); ensures minimal quiescent current in standby operation |
Pinout & Package
Hermetically sealed glass SOD80C surface-mount package: 3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height; cathode indicated by marking band.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZV55-C68,135 | ±5 % tolerance (64.6–71.4 V), higher max leakage (50 nA), same SOD80C package | Acceptable where cost sensitivity outweighs regulation precision; unsuitable for <±1 % feedback loops | Select when budget constraints dominate and system-level calibration compensates for wider voltage spread. |
| MMSZ5263B-7-F | 68 V ±5 %, 500 mW, SOD-123 package, Rth(j-a) = 460 K/W, no hermetic seal | Lower thermal performance and moisture susceptibility limit use in outdoor or high-reliability deployments | Prefer only for consumer-grade designs with controlled ambient and short product lifecycles. |
Compared with BZV55-B68,115, the BZV55-C68,135 trades voltage precision for cost, while MMSZ5263B-7-F sacrifices hermetic reliability and thermal efficiency for broader distributor availability - making the BZV55-B68,115 optimal for industrial power and sensing where long-term parametric stability is critical.

FAQ
What is the maximum continuous reverse current for BZV55-B68,115 at 25 °C?
The maximum continuous reverse (Zener) current is derived from Ptot = 500 mW and VZ ≈ 68 V, yielding IZ(max) ≈ 7.4 mA. This assumes Tamb ≤ 50 °C on a 10 × 10 × 0.6 mm ceramic substrate; derating applies above that temperature.
Does BZV55-B68,115 meet automotive qualification standards?
No. BZV55-B68,115 is not AEC-Q200 qualified and lacks automotive-specific testing, traceability, or process controls. It is intended for industrial, commercial, and general-purpose applications - not safety-critical or automotive ECUs.
How does the SOD80C package affect thermal performance compared to plastic SMD packages?
The hermetic glass SOD80C package achieves Rth(j-sp) = 300 K/W - significantly better than typical plastic SOD-123 (≈460 K/W) - due to superior heat conduction through glass and direct metal-to-solder interface, enabling higher sustained power in compact layouts.
Can BZV55-B68,115 be used in series or parallel configurations?
Series connection is permissible for higher voltage references but requires matched units to avoid current imbalance; parallel use is strongly discouraged due to negative temperature coefficient interaction and thermal runaway risk - single-device operation is recommended per datasheet guidance.
