Product details
Overview
BZV90-C22,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, rated for 22 V nominal working voltage at 5 mA test current, with ±5% tolerance, 1.5 W total power dissipation, and 15.4 Ω typical differential resistance. It serves as a precision reference or overvoltage clamp in DC power supply feedback loops and analog sensor biasing circuits.
For engineers reviewing the BZV90-C22,115 datasheet, BZV90-C22,115 pinout, BZV90-C22,115 application, or BZV90-C22,115 equivalent, key selection criteria include its 22 V regulation accuracy, low temperature coefficient (±1.25 mV/K), SOT223 thermal performance (Rth j-a = 83.3 K/W), and non-repetitive surge capability (40 W, 100 μs).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across load variations and temperature shifts. Its E24-standard 22 V rating (20.8–23.3 V min/max) and 5 mA test current align with industrial reference design practices for linear regulators and voltage monitors.
The SOT223 package features an exposed collector pad for enhanced thermal conduction, supporting continuous operation up to 150 °C junction temperature. Differential resistance of 15.4 Ω (typ.) and capacitance of 60 pF at 0 V ensure predictable dynamic response in filtering and transient suppression roles.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; tied to lower-potential node in reverse-biased Zener configuration. |

FAQ
What is the maximum continuous reverse current the BZV90-C22,115 can sustain at 25 °C?
The BZV90-C22,115 does not specify a maximum continuous reverse current rating; instead, its safe operating area is defined by total power dissipation (1500 mW at 25 °C ambient). At 22 V, this corresponds to ~68 mA continuous Zener current. Exceeding this requires derating per Rth j-a = 83.3 K/W and ambient temperature.
Can BZV90-C22,115 be used in parallel for higher current handling?
No - Zener diodes exhibit negative temperature coefficients and manufacturing spread, causing current hogging when paralleled. The datasheet does not recommend parallel operation. For higher current, use a single higher-power Zener or active regulation with a pass transistor driven by this reference.
Is the SOT223 package lead-free and RoHS compliant?
Yes - Nexperia confirms BZV90-C22,115 meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations. The device carries the "Pb-free" marking per JEDEC J-STD-609 and is compatible with standard SnAgCu reflow profiles (peak 260 °C).
How does the temperature coefficient affect regulation accuracy over −40 to +125 °C?
With ±1.25 mV/K tempco and 22 V nominal, worst-case drift is ±156 mV over 125 K span - approximately ±0.71%. Combined with ±5% initial tolerance, total regulation uncertainty remains within ±5.7% across full temperature range, verified in Fig.4/Fig.5 of the datasheet.
