Product details
Overview
BZV90-C20,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, rated for 20 V nominal working voltage (18.8–21.2 V), 1.5 W total power dissipation, and ±5% tolerance. It delivers stable reference voltage in low-to-medium current regulation circuits with differential resistance of 15 Ω at 5 mA test current and temperature coefficient of +4.5 mV/K, commonly used in power supply feedback loops and overvoltage protection.
For engineers reviewing the BZV90-C20,115 datasheet, BZV90-C20,115 pinout, BZV90-C20,115 application, or BZV90-C20,115 equivalent, key selection criteria include Zener voltage accuracy at IZtest = 5 mA, thermal resistance (83.3 K/W), non-repetitive peak reverse power (40 W), and SOT223 thermal pad layout compatibility with FR4 PCB copper area ≥2 cm².
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ across its E24-standardized 20 V nominal point, exhibiting a positive temperature coefficient (+4.5 mV/K) typical for devices above 6 V. Its differential resistance of 15 Ω ensures minimal output voltage variation under load changes up to 400 mA forward current rating.
The device uses a planar silicon junction structure optimized for stable regulation under transient surges (100 μs, 40 W peak), with reverse leakage limited to ≤0.05 μA at VR = 15 V and capacitance of 60 pF at 1 MHz / 0 V. Thermal performance relies on the SOT223 collector pad for heat conduction to PCB copper.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5242B-TP | Same 20 V nominal, but SOD-123 package (350 mW Ptot, Rth j-a = 350 K/W); no redundant terminals | Limited to low-power signal-level regulation; unsuitable for >100 mA continuous use or surge clamping | Select only for space-constrained PCBs where thermal load is <300 mW and surge immunity is not required. |
| BZX84-C20 | 20 V Zener in SOT-23; 350 mW rating, 25 Ω rdif, −2.0 mV/K tempco below 6 V range (not applicable here) | Higher impedance and lower surge rating reduce regulation accuracy and transient robustness in power applications | Preferable only for cost-sensitive consumer designs with benign thermal environments and no surge exposure. |
Compared with MMSZ5242B-TP and BZX84-C20, BZV90-C20,115 provides 4.3× higher power handling, 4.2× lower thermal resistance, and redundant cathode/anode terminals-making it uniquely suitable for industrial power regulation where reliability under thermal and electrical stress is critical.

FAQ
What is the maximum continuous reverse current this diode can regulate at 20 V?
The BZV90-C20,115 supports continuous Zener current up to approximately 75 mA at 20 V, derived from its 1500 mW power rating (P = V × I → I = 1500 mW / 20 V = 75 mA). Operation beyond this requires derating per ambient temperature and PCB copper area, as specified in the thermal resistance curve.
Does this Zener diode require a series current-limiting resistor in all applications?
Yes - a series resistor is mandatory to limit Zener current within safe operating limits. For example, at 24 V input regulating 20 V output, a minimum 53 Ω resistor is needed to restrict current to 75 mA. The resistor value must be selected based on worst-case input voltage, load current, and desired regulation margin.
Can BZV90-C20,115 replace older Philips/NXP BZV90-C20 variants?
Yes - BZV90-C20,115 is the Nexperia-manufactured successor to the original NXP/Philips BZV90-C20, retaining identical electrical specifications, SOT223 package dimensions, pinout, and thermal characteristics. The "115" suffix denotes tape-and-reel packaging per JEDEC standard, with no functional change.
How does the dual-cathode/dual-anode configuration improve reliability?
The SOT223 package's pins 2+4 (cathode) and 1+3 (anode) provide parallel current paths that reduce effective bond wire resistance and inductance. This lowers voltage overshoot during fast transients and improves thermal distribution across the die, increasing surge survivability and long-term parameter stability under repeated stress.
