Product details
Overview
BZV49-C4V7,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT89 package, designed for precision DC voltage reference and stabilization in low-to-medium current circuits. It delivers a nominal 4.7 V regulation at 5 mA test current, with ±5% tolerance, 50–80 Ω differential resistance, and −1.4 to +0.2 mV/K temperature coefficient. Used in power supply feedback loops and voltage clamping for microcontroller I/O protection.
For engineers reviewing the BZV49-C4V7,115 datasheet, BZV49-C4V7,115 pinout, BZV49-C4V7,115 application, or BZV49-C4V7,115 equivalent, this page provides verified electrical parameters, thermal behavior under surge conditions, SOT89 mounting guidance, and cross-reference alternatives for stable 4.7 V regulation in industrial and embedded systems.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 4.4–5.0 V at 5 mA test current and exhibits low dynamic impedance (50–80 Ω), enabling tight regulation under varying load currents. Its temperature coefficient ranges from −1.4 to +0.2 mV/K, indicating near-zero drift near room temperature - ideal for uncompensated reference designs.
It supports non-repetitive peak reverse power dissipation up to 40 W for 100 μs pulses and continuous power dissipation of 1 W at 25 °C on a 2.5 cm² ceramic substrate. Junction temperature is rated to 150 °C, with thermal resistance from junction to tie-point at 15 K/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 4.4–5.0 V at IZ = 5 mA - defines stable regulation range for 4.7 V nominal reference |
| Differential Resistance (rdif) | 50–80 Ω - determines output voltage variation under load current changes |
| Temperature Coefficient (SZ) | −1.4 to +0.2 mV/K - indicates minimal VZ drift across operating temperature |
| Total Power Dissipation (Ptot) | 1 W at Tamb = 25 °C - sets maximum continuous DC power handling on standard PCB mount |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 μs - enables transient overvoltage suppression without failure |
| Reverse Current (IR) | ≤3 μA at VR = 3 V - ensures low leakage in standby or high-impedance bias networks |
| Junction Temperature (Tj) | 150 °C maximum - defines upper thermal limit for reliable long-term operation |
Pinout & Package
Package: SOT89 (SC-62), plastic surface-mounted package with exposed collector pad for enhanced thermal conduction. Dimensions per JEDEC TO-243: 4.6 × 2.6 × 1.6 mm, 3-lead configuration optimized for power dissipation in space-constrained layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 1 W continuous power rating | Supports regulation in mid-current applications (e.g., op-amp references, sensor biasing) without external heatsinking |
| Low differential resistance (50–80 Ω) | Minimizes output voltage deviation under ±10 mA load variation - critical for analog signal conditioning |
| SOT89 thermal design | Exposed pad and low Rth(j–tp) = 15 K/W allow efficient heat transfer to PCB copper area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4700T1G | Same 4.7 V nominal, SOD-123 package, 500 mW Ptot, higher rdif (100 Ω typical) | Limited to ≤250 mA continuous current; unsuitable for >0.5 W sustained dissipation | Select when board space is constrained and power demand is <0.5 W |
| BZX84-C4V7 | Same 4.7 V nominal, SOT23 package, 350 mW Ptot, rdif ≈ 95 Ω | Lower thermal performance (Rth(j–a) ≈ 300 K/W); not recommended for >100 mA average current | Select for cost-sensitive, low-power signal-level regulation only |
Compared with MMSZ4700T1G and BZX84-C4V7, BZV49-C4V7,115 offers 2× higher power rating and superior thermal management via SOT89, making it the preferred choice for industrial power rails and sustained-clamp applications where reliability under thermal stress is critical.

FAQ
What is the maximum continuous forward current for BZV49-C4V7,115?
The device is rated for 250 mA continuous forward current (IF), but it is intended for reverse-bias Zener operation. Forward conduction is only relevant during transient polarity reversal or circuit fault conditions - sustained forward bias exceeds safe operating area and risks thermal runaway.
Can BZV49-C4V7,115 be used in parallel for higher current handling?
No - Zener diodes exhibit manufacturing spread in VZ and rdif, causing current imbalance. Even matched units require ballast resistors, reducing regulation accuracy. For higher current, use a single higher-rated Zener or switch to an active shunt regulator IC.
Is the SOT89 package lead-free and RoHS compliant?
Yes - Nexperia confirms BZV49-C4V7,115 meets RoHS Directive 2011/65/EU and REACH SVHC requirements. The SOT89 package uses lead-free matte tin plating on terminations and halogen-free molding compound, certified per Nexperia's material declarations.
What is the typical reverse leakage current at 3 V?
At VR = 3 V and Tj = 25 °C, reverse leakage current is ≤3 μA - verified per datasheet Table "Per type". This low leakage ensures minimal error in high-impedance bias networks and preserves battery life in always-on monitoring circuits.
