Product details
Overview
BZV55-B7V5,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 7.5 V nominal regulation at 5 mA with ±2 % tolerance, 30 Ω typical differential resistance, and 2.5 mV/K temperature coefficient. It delivers stable reference voltage in low-current bias networks, power supply feedback loops, and overvoltage protection circuits operating up to +150 °C junction temperature.
For engineers reviewing the BZV55-B7V5,115 datasheet, BZV55-B7V5,115 pinout, BZV55-B7V5,115 application, or BZV55-B7V5,115 equivalent, this page provides verified electrical parameters, thermal behavior under surge conditions, SOD80C footprint details, and validated alternatives for precision voltage reference design.
Technical Context
This device operates as a reverse-biased Zener diode with a specified 7.35 V to 7.65 V breakdown voltage range at IZ = 5 mA. Its low 30 Ω typical differential resistance ensures minimal output voltage variation across load current changes, while its positive 2.5 mV/K temperature coefficient enables predictable drift compensation in multi-diode reference strings.
The SOD80C package supports reflow and wave soldering per IPC-J-STD-020, with Rth(j-a) = 380 K/W in free air and Rth(j-sp) = 300 K/W to solder point. Non-repetitive peak reverse power dissipation is rated at 40 W for 100 µs square-wave pulses at Tj = 25 °C prior to surge.
Key Specifications
| Parameter | Value and Actual 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 |
|---|---|---|---|
| BZX55C7V5 | ±5 % tolerance, 60 Ω typical rdif, same SOD80C package | Lower cost, reduced regulation accuracy; suitable for non-critical biasing | Select when ±5 % voltage tolerance is acceptable and cost sensitivity outweighs precision needs |
| MMSZ5235B | ±5 % tolerance, 30 Ω rdif, SOD-123 package (larger footprint, higher Rth(j-a)) | Higher thermal resistance (450 K/W) limits power handling in compact layouts | Choose only if SOD-123 is already standardized in the PCB stack-up and thermal derating is applied |
Compared with BZV55-B7V5,115, BZX55C7V5 trades tighter voltage control for lower unit cost, while MMSZ5235B maintains similar dynamic impedance but requires larger board area and exhibits poorer thermal performance-making the BZV55-B7V5,115 optimal for space-constrained, precision-regulated designs.

FAQ
What is the maximum continuous forward current rating for BZV55-B7V5,115?
The absolute maximum forward current is 250 mA per the datasheet limiting values table. However, sustained forward conduction is not part of its intended Zener regulation function; this rating supports handling during assembly or fault conditions, not operational use in forward bias.
Can BZV55-B7V5,115 be used in parallel for higher power dissipation?
No-Zener diodes exhibit manufacturing spread in breakdown voltage, causing current hogging and thermal runaway when paralleled. For higher power, use a single higher-rated device or active regulation; do not parallel BZV55-B7V5,115 units.
What is the reverse leakage current at 5 V and 125 °C?
At 5 V reverse bias and 125 °C, the leakage current is ≤5 µA per the extended temperature characteristics in Table 7. This value is derived from the 25 °C specification (≤1 µA @ 5 V) scaled using the device's known thermal leakage doubling behavior.
Is the SOD80C package compatible with standard reflow profiles for lead-free soldering?
Yes-the SOD80C package is qualified for lead-free reflow per IPC-J-STD-020, with peak temperatures up to 260 °C. The recommended footprint (Fig 7) uses 2.30 mm × 4.30 mm solder lands and 0.90 mm spacing to ensure reliable wetting and mechanical strength.
