Product details
Overview
BZV55-C7V5,115 from Nexperia is a 7.5 V ±5 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 400 mW total power dissipation at ≤50 °C ambient, with 1 µA reverse leakage at 5 V and 30–80 Ω differential resistance at 5 mA, used for low-power voltage regulation in signal conditioning and reference circuits.
For engineers reviewing the BZV55-C7V5,115 datasheet, BZV55-C7V5,115 pinout, BZV55-C7V5,115 application, or BZV55-C7V5,115 equivalent, this part serves as a precision, low-current voltage reference in analog front-ends, sensor biasing networks, and overvoltage protection clamping where stable 7.5 V regulation under 5 mA operating current is required.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 7.5 V reference across its terminals when reverse-biased above its nominal Zener voltage. It exhibits a positive temperature coefficient of +2.5 to +5.3 mV/K at 5 mA, enabling predictable thermal drift in compensated designs.
Its SOD80C package provides hermetic sealing for long-term stability and moisture resistance, while its low 150 pF junction capacitance (at 0 V, 1 MHz) supports use in moderate-frequency signal paths without significant loading effects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.0 V to 7.9 V (±5 % tolerance at IZ = 5 mA); defines regulated output voltage range under nominal bias |
| Differential Resistance (rdif) | 30 Ω to 80 Ω (typ. 40 Ω at IZ = 5 mA); determines output impedance and load regulation sensitivity |
| Reverse Leakage Current (IR) | ≤1 µA at VR = 5 V; ensures minimal quiescent current draw in standby or high-impedance reference nodes |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤50 °C; sets maximum continuous DC power handling on standard PCB layout |
| Junction-to-Ambient Thermal Resistance (Rth(j-a)) | 380 K/W in free air; limits steady-state temperature rise to ~152 °C above ambient at full 400 mW |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for 100 µs square wave; enables short-duration surge clamping in transient protection circuits |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA; supports use as a low-drop rectifier or ESD clamp in forward conduction |
Pinout & Package
The BZV55-C7V5,115 is housed in a hermetically sealed glass SOD80C surface-mount package measuring 3.3–3.7 mm length × 1.45–1.60 mm width × 0.3 mm height, with cathode indicated by a marking band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-bias voltage applied here relative to anode to enable Zener conduction |
| 2 | Anode | Connected to circuit ground or lower-potential rail; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass SMD packaging | Ensures long-term parameter stability and immunity to humidity-induced leakage drift in industrial environments |
| ±5 % Zener voltage tolerance | Provides cost-optimized regulation accuracy suitable for non-critical biasing and clamping applications |
| Low 150 pF junction capacitance | Minimizes signal distortion and phase shift in AC-coupled reference or feedback paths up to ~1 MHz |
| 40 W non-repetitive peak power rating | Supports transient overvoltage suppression in low-energy surge events without device failure |
| 30–80 Ω differential resistance | Delivers predictable load regulation error of <±0.4 V per 10 mA load change at 7.5 V nominal output |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C7V5 | Same 7.5 V ±5 % rating, but in larger DO-35 glass axial package; higher Ptot = 500 mW; Rth(j-a) = 500 K/W | Requires through-hole mounting and more board area; better suited for prototyping or high-reliability linear supplies | Select for manual assembly or where thermal margin exceeds SMD constraints |
| MMSZ5235B | 7.5 V ±5 % in SOD-123; Ptot = 350 mW; rdif = 30 Ω typ.; Rth(j-a) = 350 K/W; Cd = 30 pF | Lower capacitance improves RF performance; reduced power rating limits sustained current capability | Select for space-constrained RF biasing or where <30 pF capacitance is critical |
Compared with BZX55-C7V5, BZV55-C7V5,115 offers superior board-area efficiency and hermetic reliability in SMD layouts, while MMSZ5235B trades slightly lower power handling for tighter high-frequency response-making BZV55-C7V5,115 optimal for general-purpose industrial regulation where size, stability, and surge resilience are prioritized.

FAQ
What is the maximum continuous reverse current the BZV55-C7V5,115 can sustain at 7.5 V?
The device is rated for 400 mW total power dissipation at ambient ≤50 °C. At 7.5 V, this corresponds to a maximum continuous reverse current of 53.3 mA (400 mW ÷ 7.5 V). Exceeding this value risks thermal runaway due to its 380 K/W junction-to-ambient thermal resistance.
Does the BZV55-C7V5,115 require a series current-limiting resistor in all applications?
Yes - a series resistor is mandatory to limit reverse current to within the device's safe operating area. For example, with a 12 V supply and 7.5 V regulation target, a minimum 85 Ω resistor is required to keep current ≤53 mA at full power; actual value must account for worst-case VZ tolerance and temperature drift.
How does the temperature coefficient affect regulation accuracy over –40 °C to +125 °C?
With a specified +2.5 to +5.3 mV/K coefficient at 5 mA, the Zener voltage shifts +0.45 V to +0.95 V across an 180 K temperature span. This results in ±3–6 % deviation from nominal 7.5 V, making it unsuitable for wide-temperature precision references without external compensation.
Can the BZV55-C7V5,115 be used in forward conduction mode as a standard diode?
Yes - its forward voltage is ≤0.9 V at 10 mA, matching typical silicon diode behavior. It supports roles such as polarity protection or low-current rectification, though its 250 mA absolute maximum forward current is lower than dedicated rectifiers like 1N4148.
