Product details
Overview
BZV49-C5V6 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 5.6 V working voltage at 5 mA test current, with ±5% tolerance, 15 Ω typical differential resistance, and +2.5 mV/K temperature coefficient. Used in low-noise analog biasing and overvoltage protection circuits.
For engineers reviewing the BZV49-C5V6 datasheet, BZV49-C5V6 pinout, BZV49-C5V6 application, or BZV49-C5V6 equivalent, key selection criteria include Zener voltage accuracy at 5 mA, thermal resistance (15 K/W junction-to-tie-point), non-repetitive peak reverse power capability (40 W), and SOT89 thermal pad layout compatibility.
Technical Context
The BZV49-C5V6 operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse current above its breakdown threshold. Its design centers on low dynamic impedance (15–40 Ω) and controlled positive temperature coefficient (+2.5 mV/K), enabling predictable drift compensation in series-biased reference chains.
It is optimized for surface-mount applications requiring moderate power dissipation (1 W continuous) and robust transient handling (40 W non-repetitive, 100 μs pulse). The SOT89 package's exposed collector pad provides enhanced thermal transfer to PCB copper, critical for sustained regulation under load variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.2–6.0 V at IZtest = 5 mA; ensures stable 5.6 V reference within ±5% across production lot |
| Differential Resistance rdif | 15–40 Ω at IZtest = 5 mA; determines output impedance and load regulation sensitivity |
| Temp. Coefficient SZ | +2.5 mV/K at IZtest = 5 mA; enables predictable voltage drift for temperature-compensated references |
| Max. Power Dissipation Ptot | 1 W at Tamb = 25 °C on ceramic substrate; defines continuous thermal budget in PCB layout |
| Non-repetitive Peak Power | 40 W at tp = 100 μs; supports surge suppression in transient-limited protection circuits |
| Reverse Current IR | ≤1 μA at VR = 1 V; guarantees low leakage in high-impedance bias networks |
| Junction Temperature | 150 °C max; sets upper limit for thermal derating in enclosed industrial environments |
Pinout & Package
SOT89 (SC-62) plastic surface-mount package with exposed collector pad for thermal conduction; 3-lead outline per JEDEC TO-243, footprint optimized for 2.5 cm² ceramic substrate mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary forward current entry; connected to ground or low-side return path in shunt configuration |
| 2 | Cathode | Zener breakdown terminal; connects to regulated node and current-limiting resistor |
| 3 | Anode | Second anode tie point; electrically common with Pin 1, enhances thermal conduction via PCB copper fill |
Key Features
| Feature | Design Value |
|---|---|
| E24 Standard Voltage Range | 5.6 V nominal with ±5% tolerance - enables direct replacement in legacy 5 V rail designs without recalibration |
| Low Differential Impedance | 15 Ω typical at 5 mA - minimizes output voltage shift under varying load current (e.g., ±10 mA → ±150 mV) |
| Controlled Temp. Coefficient | +2.5 mV/K - allows pairing with negative-coefficient devices for zero-drift reference strings |
| Robust Transient Handling | 40 W non-repetitive peak power - clamps ESD or inductive spikes without degradation in 100 μs events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 | Same 5.6 V rating but SOT23 package; higher rdif (40–70 Ω); no thermal pad | Limited to ≤300 mW continuous power; unsuitable for >50 mA regulation loads | Select when board space is constrained and thermal load is light |
| MMSZ5232B | 5.6 V, SOD-123; 100 mW Ptot; rdif ≈ 10 Ω; tighter ±5% tolerance | Not rated for 40 W surge; intended for low-power bias only, not protection | Select for portable battery-powered sensor nodes where size and quiescent current dominate |
Compared with BZX84-C5V6 and MMSZ5232B, the BZV49-C5V6 uniquely supports 1 W continuous regulation and 40 W transient clamping in a thermally enhanced SOT89 package-making it the only choice for industrial power rail stabilization where both steady-state accuracy and surge resilience are required.

FAQ
What is the maximum continuous reverse current the BZV49-C5V6 can handle at 25 °C?
The BZV49-C5V6 does not specify a maximum continuous reverse current; instead, it is rated for 1 W total power dissipation at 25 °C ambient. At its nominal 5.6 V Zener voltage, this corresponds to approximately 179 mA continuous reverse current (IZ = Ptot/VZ). Derating is required above 25 °C per Rth(j-a) = 125 K/W.
Can the BZV49-C5V6 be used in parallel for higher current capability?
No-Zener diodes like the BZV49-C5V6 should not be paralleled without individual ballasting resistors. Minor unit-to-unit VZ variations (±5%) cause current hogging, leading to thermal runaway and failure. For higher current, use a single higher-power device or active regulation.
Is the SOT89 package lead-free and RoHS compliant?
Yes-the BZV49-C5V6 is manufactured in accordance with Nexperia's standard RoHS-compliant processes. The SOT89 package uses lead-free terminations and meets EU Directive 2011/65/EU requirements, with full compliance documentation available in Nexperia's product change notifications.
How does the +2.5 mV/K temperature coefficient affect circuit performance?
The +2.5 mV/K coefficient means the Zener voltage increases by ~2.5 mV per Kelvin rise in junction temperature. At 70 °C ambient (assuming 50 °C rise), VZ rises ~125 mV above its 25 °C value. This must be accounted for in precision references-often mitigated by pairing with a negative-TC device or using temperature-compensated topologies.
