Product details
Overview
BZV49-C10,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT89 package, designed for precision DC voltage reference and stabilization in power supply rails. It delivers a nominal 10 V regulation at 5 mA test current, with ±5% tolerance, 8 Ω typical differential resistance, and 4.5 mV/K temperature coefficient. Used in low-noise analog supply conditioning for industrial sensor interfaces.
For engineers reviewing the BZV49-C10,115 datasheet, BZV49-C10,115 pinout, BZV49-C10,115 application, or BZV49-C10,115 equivalent, key selection criteria include Zener voltage accuracy at IZ = 5 mA, thermal resistance (Rth(j-tp) = 15 K/W), non-repetitive surge capability (40 W @ 100 μs), and SOT89 thermal pad layout compatibility.
Technical Context
This device operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse current above its breakdown threshold. Its E24-standard 10 V nominal rating (9.4–10.6 V range) and low 8 Ω dynamic impedance ensure tight regulation under varying load conditions.
Thermal design relies on the SOT89's exposed collector pad for heat transfer to PCB copper; junction-to-tie-point thermal resistance is 15 K/W when mounted on a 2.5 cm² ceramic substrate. Temperature coefficient of +4.5 mV/K enables predictable drift compensation in bias networks.
Key Specifications

| Differential Resistance rdiff | 8–20 Ω at IZ = 5 mA; determines output voltage variation under load current changes |
| Temperature Coefficient SZ | +4.5 mV/K at IZ = 5 mA; enables predictable thermal drift modeling in precision references |
| Total Power Dissipation Ptot | 1 W at Tamb = 25 °C; defines maximum continuous DC power handling on standard PCB layout |

| Reverse Current IR | ≤0.2 μA at VR = 7.6 V; guarantees minimal leakage in high-impedance bias networks |
| Junction Temperature Tj | 150 °C max; sets upper thermal limit for reliability in enclosed industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10 | Same 10 V nominal rating but SOT23 package; Rth(j-a) = 300 K/W vs. 125 K/W for SOT89 | Limited to ≤150 mW continuous dissipation; unsuitable for >10 mA current-sink loads | Select when board space is constrained and thermal load is <100 mW. |
| MMSZ5240B | 10 V Zener in SOD-123; 500 mW Ptot; rdiff = 17 Ω; no thermal pad | Higher impedance causes >85 mV regulation shift across 5 mA load change; no surge rating specified | Select only for cost-sensitive consumer applications with benign thermal environments. |
Compared with BZX84-C10 and MMSZ5240B, the BZV49-C10,115 provides superior thermal performance (15 K/W Rth(j-tp)) and robust 40 W surge handling-critical for industrial and automotive power-rail stabilization where sustained current and transient immunity are mandatory.

FAQ
What is the maximum continuous forward current rating for BZV49-C10,115?
The BZV49-C10,115 is rated for 250 mA continuous forward current (IF), though it is operated in reverse-bias Zener mode in normal use. Forward conduction is relevant only during circuit power-up sequencing or fault conditions where polarity may be momentarily reversed.
How does the SOT89 package improve thermal performance compared to SOT23 Zeners?
The SOT89 package features an exposed collector pad that serves as a dedicated thermal path to the PCB copper pour, achieving Rth(j-tp) = 15 K/W-over 5× better than typical SOT23 devices. This allows 1 W continuous dissipation without heatsinking, whereas SOT23 variants are limited to ~150 mW.
Can BZV49-C10,115 be used in series or parallel configurations for higher voltage or current handling?
No-Zener diodes like BZV49-C10,115 must not be paralleled due to mismatched breakdown voltages causing current hogging and thermal runaway. Series connection is possible for higher voltage, but requires individual current-limiting resistors and derating for thermal coupling effects.
What is the significance of the "115" suffix in BZV49-C10,115?
The "115" is Nexperia's internal ordering code denoting tape-and-reel packaging in 1000-unit reels, compliant with EIA-481-D standards. It does not affect electrical specifications-the core device remains identical to BZV49-C10 in all parametric and thermal characteristics.
