Product details
Overview
BZV49-C6V2,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT89 package, designed for precision DC voltage reference and regulation in power supply feedback paths. It delivers a nominal 6.2 V working voltage at 5 mA test current, with ±5% tolerance, 6–10 Ω differential resistance, and low 0.4–3.7 mV/K temperature coefficient. Used in industrial power adapters and automotive sensor biasing circuits.
For engineers reviewing the BZV49-C6V2,115 datasheet, BZV49-C6V2,115 pinout, BZV49-C6V2,115 application, or BZV49-C6V2,115 equivalent, this page provides verified electrical parameters, thermal behavior under surge conditions, SOT89 mounting guidance, and validated alternatives for voltage reference design continuity.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified 6.2 V nominal Zener voltage (VZ) at IZtest = 5 mA, exhibiting tight 5.8–6.6 V min/max range and low dynamic impedance (6–10 Ω). Its temperature coefficient (SZ) ranges from +0.4 to +3.7 mV/K, indicating positive drift optimized for stable mid-range voltage references.
Rated for 1 W total power dissipation at Tamb = 25 °C on ceramic substrate (2.5 cm²), it supports non-repetitive peak reverse power up to 40 W (100 μs square wave). Junction-to-tie-point thermal resistance is 15 K/W, enabling effective heat transfer via the exposed collector pad in SOT89.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8–6.6 V at 5 mA - defines regulated output voltage window in feedback loops |
| Differential Resistance (rdif) | 6–10 Ω - determines load regulation sensitivity and ripple rejection capability |
| Temperature Coefficient (SZ) | +0.4 to +3.7 mV/K - quantifies voltage drift over temperature; enables compensation design |
| Total Power Dissipation (Ptot) | 1 W at 25 °C ambient - sets maximum continuous DC power handling on standard PCB layout |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 μs - supports transient overvoltage clamping without failure |
| Reverse Current (IR) | ≤3 μA at VR = 3 V - ensures minimal leakage in high-impedance bias networks |
| Junction Temperature (Tj) | −65 to +150 °C - specifies operational envelope for automotive and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4685-7-F (Diodes Inc.) | Same 6.2 V nominal, but ±5% tolerance achieved via tighter binning; 15 Ω rdif; no thermal pad | Lacks SOT89 thermal pad → higher Rth(j-a) (300 K/W vs. 125 K/W); unsuitable for >300 mW continuous use | Select when cost-sensitive and thermal load <300 mW; verify layout derating for ambient >70 °C |
| BZX84-C6V2 (Nexperia) | Same 6.2 V, ±5%, but SOT23 package; 150 mW Ptot; 40 Ω rdif; 350 pF capacitance | Lower power rating and higher impedance limit use to signal-level references, not power rail regulation | Choose only for space-constrained signal conditioning; avoid in feedback paths requiring <10 Ω impedance |
Compared with MMSZ4685-7-F and BZX84-C6V2, the BZV49-C6V2,115 uniquely combines 1 W power handling, low 6–10 Ω impedance, and SOT89 thermal pad - making it the sole option among the three for robust, high-current voltage regulation in industrial power supplies.

FAQ
What is the maximum continuous reverse current the BZV49-C6V2,115 can handle?
The device is rated for continuous forward current (IF) up to 250 mA, but as a Zener diode, its continuous reverse current is limited by power dissipation. At 25 °C ambient, 1 W Ptot allows ~161 mA at 6.2 V (P = V × I), derated linearly above 25 °C using Rth(j-a) = 125 K/W. Operation beyond this risks thermal runaway.
Does the BZV49-C6V2,115 require a heatsink for 1 W operation?
No external heatsink is required if mounted on a 2.5 cm² ceramic substrate per datasheet condition. On standard FR4 PCB with 1 oz copper, thermal performance drops significantly; design must limit average power to ≤300 mW or add copper pour under Pin 3 to emulate the specified thermal interface.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With SZ = +0.4 to +3.7 mV/K, VZ shifts +230 to +2150 mV across that range. For example, at +125 °C, nominal 6.2 V may rise to 6.43–8.35 V depending on unit variation. Precision designs must either select units with lower SZ or implement software/hardware compensation.
Can BZV49-C6V2,115 replace BZX84-C6V2 in existing SOT23 footprints?
No - BZV49-C6V2,115 uses SOT89 (4.6 × 2.6 mm), while BZX84-C6V2 uses SOT23 (3.0 × 1.4 mm). The packages are mechanically incompatible, and SOT89 requires different pad layout, solder stencil, and reflow profile due to the thermal pad. Board redesign is mandatory.
