Product details
Overview
BZV49-C5V1,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT89 package, designed for precision DC voltage reference and regulation at 5.1 V nominal working voltage with ±5% tolerance, 40 Ω typical differential resistance at 5 mA test current, and 2 μA maximum reverse leakage at 3.0 V. It delivers stable regulation in power supply feedback paths and overvoltage protection circuits.
For engineers reviewing the BZV49-C5V1,115 datasheet, BZV49-C5V1,115 pinout, BZV49-C5V1,115 application, or BZV49-C5V1,115 equivalent, this page provides verified electrical parameters, thermal performance data, SOT89 terminal mapping, and validated alternative parts for voltage reference design and board-level protection.
Technical Context
The BZV49-C5V1,115 operates as a two-terminal shunt regulator with fixed 5.1 V breakdown voltage, optimized for stable operation across −65 °C to +150 °C junction temperature range. Its low 40 Ω differential resistance ensures minimal output voltage variation under load changes, while its +1.2 mV/K temperature coefficient enables predictable drift behavior in ambient-varying environments.
Designed for surface-mount use on ceramic substrates (2.5 cm², 0.7 mm thick), it achieves 15 K/W junction-to-tie-point thermal resistance and supports non-repetitive peak reverse power dissipation up to 40 W for 100 μs pulses-critical for transient suppression in regulated supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 4.8 V to 5.4 V at 5 mA test current - defines precise regulation band for feedback loop stability |
| Differential Resistance (rdif) | 40 Ω typical at 5 mA - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | +1.2 mV/K at 5 mA - quantifies voltage drift per degree Celsius for thermal design margining |
| Total Power Dissipation (Ptot) | 1 W at Tamb = 25 °C - sets continuous thermal limit for PCB layout and heatsinking |
| Reverse Current (IR) | ≤2 μA at VR = 3.0 V - ensures low standby leakage in battery-powered or high-impedance bias networks |
| Diode Capacitance (Cd) | 300 pF at 1 MHz, VR = 0 V - impacts high-frequency noise rejection and loop stability in switching regulators |
Pinout & Package
Package: SOT89 (SC-62), plastic surface-mounted package with exposed collector pad for enhanced thermal conduction. Dimensions per JEDEC TO-243 outline: 4.6 × 2.6 × 1.6 mm, 3-lead configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary current entry point during forward conduction; tied to ground or low-side reference in shunt regulator topology |

| 3 | Anode | Second anode terminal electrically connected to Pin 1; used for mechanical anchoring and thermal path to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| E24 ±5% voltage tolerance | Enables interchangeability within standard resistor ladder designs without recalibration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1 | Same 5.1 V nominal, but SOT23 package; 500 mW Ptot; 90 Ω rdif; 5 μA IR at 3 V | Limited to lower-power biasing due to reduced thermal mass and higher impedance | Select when board space is constrained and power <0.5 W; avoid in high-stability feedback loops |
| MMSZ5231B | 5.1 V nominal, SOD-123 package; 500 mW Ptot; 17 Ω rdif; 1 μA IR at 3 V | Better low-current regulation but lower surge handling (25 W peak) | Prefer for ultra-low-leakage sensor bias; not recommended for transient-heavy industrial rails |
Compared with BZX84-C5V1 and MMSZ5231B, the BZV49-C5V1,115 offers superior thermal performance and surge resilience due to its SOT89 package and 1 W rating, making it optimal for industrial power regulation where long-term stability and pulse robustness are critical.

FAQ
What is the maximum continuous reverse power dissipation for BZV49-C5V1,115?
The BZV49-C5V1,115 has a total power dissipation rating of 1 W at ambient temperature of 25 °C when mounted on a 2.5 cm² ceramic substrate. This value decreases with rising ambient temperature per its 125 K/W junction-to-ambient thermal resistance, requiring derating above 25 °C.
Can BZV49-C5V1,115 be used in place of a 5 V linear regulator IC?
No-it is a two-terminal Zener diode, not a three-terminal regulator IC. It requires an external current-limiting resistor and provides only shunt regulation. It cannot source load current or maintain regulation under variable load without supporting circuitry like a pass transistor.
What is the significance of the "115" suffix in BZV49-C5V1,115?
The "115" is Nexperia's internal ordering code denoting tape-and-reel packaging (1000 pcs/reel), RoHS-compliant finish, and standard reliability screening. It does not affect electrical characteristics-BZV49-C5V1 and BZV49-C5V1,115 share identical electrical and thermal specifications.
How does the temperature coefficient affect regulation accuracy over temperature?
With a +1.2 mV/K coefficient, the BZV49-C5V1,115's Zener voltage increases by ~120 mV over a 100 °C rise (e.g., from 25 °C to 125 °C). For applications requiring <1% drift, this must be compensated via circuit design or selected alongside complementary components.
