Product details
Overview
BZV49-C22,115 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 working voltage of 22 V at 5 mA test current, with ±5% tolerance, 20 Ω typical differential resistance, and −5.0 mV/K temperature coefficient. Used in industrial power monitoring circuits requiring stable 22 V regulation under variable load and temperature.
For engineers reviewing the BZV49-C22,115 datasheet, BZV49-C22,115 pinout, BZV49-C22,115 application, or BZV49-C22,115 equivalent, this page provides verified electrical parameters, thermal behavior, SOT89 terminal mapping, real-world use cases, and validated alternative parts for voltage reference design and replacement planning.
Technical Context
The BZV49-C22 operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse current above its 22 V breakdown threshold. Its differential resistance of 20 Ω (typ.) ensures low dynamic impedance across 1–10 mA operating range, while the negative temperature coefficient (−5.0 mV/K) enables predictable drift compensation in multi-diode references.
Thermal performance is defined by Rth(j-tp) = 15 K/W to the tie-point and Rth(j-a) = 125 K/W to ambient on a 2.5 cm² ceramic substrate. Non-repetitive peak reverse power dissipation reaches 40 W for 100 μs pulses, supporting transient overvoltage clamping in regulated supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 20.8 V to 23.3 V at IZtest = 5 mA - defines stable regulation band for 22 V rail design |
| Differential Resistance (rdif) | 20 Ω (typ.) - ensures minimal output voltage shift under ±1 mA load variation |
| Temperature Coefficient (SZ) | −5.0 mV/K - enables predictable voltage drift for thermal compensation networks |
| Total Power Dissipation (Ptot) | 1 W at Tamb = 25 °C - sets maximum continuous DC power handling on standard PCB |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 μs - supports surge suppression without device failure |
| Reverse Current (IR) | ≤0.05 μA at VR = 17 V - guarantees low leakage in high-impedance bias networks |
| Junction Temperature (Tj) | 150 °C max - determines safe operating margin in enclosed industrial enclosures |

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-C22 | Same 22 V nominal voltage but SOT23 package; 350 mW Ptot; 50 Ω rdif | Limited to low-power biasing due to lower power rating and higher impedance | Select when board space is constrained and load current ≤5 mA |
| MMSZ4686 | 22.1 V nominal; SOD-123 package; 500 mW Ptot; 30 Ω rdif; −4.5 mV/K tempco | Lower thermal mass limits surge handling; no tie-point thermal pad | Choose for cost-sensitive consumer designs where 40 W pulse rating is unnecessary |
Compared with BZX84-C22 and MMSZ4686, the BZV49-C22,115 offers superior thermal robustness via SOT89's thermal pad and 1 W continuous rating-critical for industrial power rails-while its tighter 20 Ω impedance and matched −5.0 mV/K tempco support higher-accuracy reference designs.

FAQ
What is the maximum continuous reverse current the BZV49-C22,115 can handle at 25 °C?
The BZV49-C22,115 supports up to 45 mA continuous reverse current at 25 °C ambient, derived from its 1 W total power dissipation rating and 22 V nominal Zener voltage (IZ = Ptot/VZ ≈ 45 mA). Derating applies above 25 °C per the 125 K/W junction-to-ambient thermal resistance.
Can the BZV49-C22,115 be used in parallel for higher power handling?
No-parallel operation is not recommended due to mismatch in Zener voltage and temperature coefficient between units, causing current hogging and thermal runaway. For higher power, use a single higher-rated device or active regulation with a pass transistor.
How does the SOT89 package improve thermal performance versus SOT23?
The SOT89 package features an exposed thermal pad (Pin 3) that provides direct thermal conduction to PCB copper, reducing Rth(j-tp) to 15 K/W versus ~200 K/W for SOT23. This allows 1 W continuous operation without heatsinking, whereas SOT23 variants are limited to ~350 mW.
Is the BZV49-C22,115 suitable for automotive AEC-Q200 compliance?
The BZV49-C22,115 is not AEC-Q200 qualified. While it meets industrial temperature range (−65 °C to +150 °C), Nexperia offers AEC-Q200-qualified equivalents like the BZX84-A22 in SOT23 for automotive applications requiring stress-tested reliability.
