Product details
Overview
BZV90-C16,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and stabilization in power supply rails. It delivers a nominal Zener voltage of 16 V at 5 mA test current, with ±5% tolerance, 10.4 Ω typical differential resistance, and −1.5 mV/K temperature coefficient. Used in industrial power supplies and analog sensor biasing circuits where stable 16 V regulation is required.
For engineers reviewing the BZV90-C16,115 datasheet, BZV90-C16,115 pinout, BZV90-C16,115 application, or BZV90-C16,115 equivalent, key selection considerations include Zener voltage accuracy at 5 mA, thermal resistance (83.3 K/W), non-repetitive peak reverse power (40 W), and SOT223 thermal pad layout compatibility.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ = 15.3–17.1 V range and low dynamic impedance (max 40 Ω) to maintain regulation under varying load currents. Its negative temperature coefficient (−1.5 mV/K) enables predictable drift compensation in multi-diode references.
The SOT223 package features an exposed collector pad (Pin 3) for enhanced thermal dissipation, supporting 1.5 W continuous power at Tamb = 25 °C on 2 cm² FR4 copper. Non-repetitive surge capability reaches 11.2 A at 100 μs pulse width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.3 V min / 17.1 V max at IZtest = 5 mA - defines regulated output voltage window under standard test conditions |
| Differential Resistance (rdif) | 10.4 Ω typ / 40 Ω max at IZtest = 5 mA - determines load regulation error sensitivity to current changes |
| Temperature Coefficient (SZ) | −1.5 mV/K typ - quantifies voltage drift per degree Celsius rise, enabling thermal stability analysis |
| Total Power Dissipation (Ptot) | 1500 mW max at Tamb = 25 °C on 2 cm² FR4 PCB - sets maximum steady-state thermal design limit |
| Non-repetitive Peak Power (PZSM) | 40 W max at tp = 100 μs - supports transient overvoltage clamping without failure |
| Reverse Current (IR) | 0.05 μA max at VR = 12 V - ensures minimal leakage in high-impedance bias networks |
| Diode Capacitance (Cd) | 75 pF max at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering and AC response |
Pinout & Package
SOT223 plastic surface-mount package with integrated thermal pad (Pin 3). Designed for high thermal conductivity via copper pour under Pin 3; leads are gull-wing formed for reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; used for forward conduction or cathode-referenced Zener configuration |
| 2, 4 | Cathode | Parallel cathode terminals; provide low-inductance, low-resistance path to regulated output node |
| 3 | Thermal Pad / Collector | Exposed copper pad for PCB thermal anchoring; not electrically connected internally but critical for heat transfer |
Key Features
| Feature | Design Value |
|---|---|
| E24 Standard Voltage Range | 16 V nominal with ±5% tolerance - enables direct replacement in legacy designs using industry-standard Zener values |
| Low Differential Resistance | 10.4 Ω typical at 5 mA - improves regulation accuracy under ±10% load current variation |
| High Surge Withstand | 40 W non-repetitive peak power at 100 μs - protects downstream circuitry from short-duration transients |
| SOT223 Thermal Performance | 83.3 K/W junction-to-ambient thermal resistance - allows 1.5 W operation with <125 °C junction rise on standard PCB |
| Low Leakage Current | 0.05 μA max at 12 V reverse - preserves battery life and signal integrity in high-impedance monitoring paths |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16 | Same 16 V nominal rating but SOT23 package; lower Ptot = 300 mW; higher rdif = 40 Ω typ | Limited to low-power signal-level references; unsuitable for >100 mA load regulation | Select when board space is constrained and thermal budget permits only 300 mW dissipation |
| MMSZ5245B | SOD-123 package; 16 V rating; Ptot = 500 mW; rdif = 20 Ω typ; SZ = −1.2 mV/K | Lower surge rating (25 W); no thermal pad; less stable under thermal cycling | Choose for cost-sensitive consumer applications where 500 mW continuous power suffices |

FAQ
What is the recommended PCB layout for optimal thermal performance of BZV90-C16,115?
Maximize copper area under Pin 3 (thermal pad) with ≥2 cm² double-sided FR4 copper pour connected via ≥4 thermal vias to internal ground planes. Keep traces to Pins 2 and 4 short and wide to minimize inductance during surge events. Avoid solder mask over the thermal pad to ensure direct copper contact.
Can BZV90-C16,115 be used in series or parallel configurations for higher voltage or current handling?
Series connection is valid for higher voltage references (e.g., two 16 V diodes for ~32 V), provided matched temperature coefficients are selected. Parallel use is not recommended due to mismatched Zener impedances causing current imbalance and thermal runaway; external ballast resistors are required if attempted.
What is the maximum allowable reverse voltage before breakdown in normal operation?
The rated working voltage is 16 V nominal, with guaranteed breakdown between 15.3 V and 17.1 V at 5 mA. Operation below 12 V reverse bias ensures <0.05 μA leakage; sustained reverse voltage above 17.1 V risks irreversible avalanche degradation unless limited by series impedance.
How does the temperature coefficient affect long-term stability in a 70 °C ambient environment?
With SZ = −1.5 mV/K, a 45 °C rise from 25 °C test condition shifts VZ by −67.5 mV (≈ −0.42%). Combined with ±5% initial tolerance, total system variation remains within ±5.5% across −40 °C to +125 °C junction range, meeting industrial grade requirements.
