Product details
Overview
BZV55-C75,115 from Nexperia is a 75 V ±5 % tolerance 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 low-power voltage reference and regulation in analog sensor interfaces and power supply feedback networks.
For engineers reviewing the BZV55-C75,115 datasheet, BZV55-C75,115 pinout, BZV55-C75,115 application, or BZV55-C75,115 equivalent, key selection criteria include nominal Zener voltage (75 V), tolerance (±5 %), differential resistance (170 Ω typ. at IZ = 2 mA), temperature coefficient (+95 mV/K), and SOD80C thermal resistance (300 K/W junction-to-solder-point).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable DC reference voltage under varying load and temperature conditions. Its 75 V nominal Zener voltage is specified at IZ = 2 mA with a typical differential resistance of 170 Ω and a positive temperature coefficient of +95 mV/K, indicating voltage increases with junction temperature.
The device uses a hermetically sealed glass SOD80C package with two terminals (anode and cathode), enabling reliable operation up to 200 °C storage temperature and supporting reflow/wave soldering per JEDEC standards. Thermal resistance from junction to solder point is 300 K/W, critical for derating in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 75 V nominal, ±5 % tolerance (70–79 V range), defined at IZ = 2 mA for stable reference generation |
| Differential Resistance (rdif) | 170 Ω typical at IZ = 2 mA - determines output impedance and regulation sensitivity to current changes |
| Temperature Coefficient (SZ) | +95 mV/K - quantifies Zener voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 500 mW maximum at Tamb ≤ 50 °C on ceramic substrate - sets continuous DC power handling limit |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for 100 µs square wave - defines surge immunity in transient overvoltage protection |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - ensures low conduction loss when forward-biased |
| Reverse Current (IR) | ≤ 50 nA at VR = 0.7 × VZ(nom) = 52.5 V - confirms high blocking integrity near operating voltage |
Pinout & Package
Hermetically sealed glass SOD80C 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 |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for regulation current |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass SMD packaging | Ensures long-term stability and moisture resistance in harsh environments without conformal coating |
| ±5 % Zener voltage tolerance | Enables cost-effective voltage referencing where tight initial accuracy is not required |
| Low differential resistance (170 Ω typ.) | Minimizes output voltage variation under ±1 mA load current shifts in feedback loops |
| High surge capability (40 W, 100 µs) | Withstands ESD and line transients without degradation in power supply clamp circuits |
| Wide operating temperature range | Junction temperature rating of −65 °C to +200 °C supports industrial and automotive under-hood applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C75 | Same 75 V ±5 % rating but in larger DO-35 glass axial package; higher Ptot = 500 mW but Rth(j-a) = 500 K/W vs. 380 K/W | Suitable for through-hole prototyping or legacy board upgrades; less suitable for dense SMD layouts | Select when manual assembly or socket testing is required; avoid in thermally constrained SMT designs |
| MMSZ5265B | 75 V ±5 % in SOD-123; lower Ptot = 350 mW; rdif = 200 Ω typ.; Tj max = 150 °C | Lower power and temperature capability limits use in high-ambient industrial enclosures | Choose only for space-constrained consumer-grade designs where 150 °C junction limit suffices |
Compared with BZV55-C75,115, BZX55-C75 offers easier hand-soldering but poorer thermal performance in SMT assemblies, while MMSZ5265B sacrifices 30 % power headroom and 50 °C junction margin for smaller footprint-making the BZV55-C75,115 optimal for thermally demanding industrial SMT regulation.

FAQ
What is the maximum continuous reverse current the BZV55-C75,115 can sustain at 75 V?
The BZV55-C75,115 is not rated for continuous operation at its nominal Zener voltage. At VR = 52.5 V (0.7 × VZ(nom)), reverse current is ≤50 nA. For sustained regulation, it must be biased at IZ = 2 mA per datasheet test condition - corresponding to ~150 µW static power, well within its 500 mW limit.
How does the +95 mV/K temperature coefficient affect circuit design?
The positive temperature coefficient means output voltage rises ~95 mV per °C increase in junction temperature. In precision references, this requires either thermal compensation (e.g., NTC network) or operation within a narrow ambient range (±10 °C) to hold regulation error below ±0.1 %.
Can BZV55-C75,115 replace BZV55-B75 in an existing design?
No - BZV55-B75 has ±2 % tolerance (73.5–76.5 V) versus ±5 % for the C-grade (70–79 V). Substituting introduces up to 2.5 V additional uncertainty in regulation setpoint, potentially violating safety margins in overvoltage protection circuits or degrading ADC reference accuracy beyond spec.
Is the SOD80C package compatible with standard reflow profiles?
Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The SOD80C footprint (2.30 × 4.30 mm solder lands) supports peak temperatures up to 260 °C for ≤10 seconds, provided thermal mass and board layout allow uniform heating of the hermetically sealed glass body without cracking.
