Product details
Overview
BZV90-C15,115 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 15 V at 5 mA test current, with ±5% tolerance, 10 Ω typical differential resistance, and −5.0 to +4.0 mV/K temperature coefficient. Used in industrial power supplies and analog sensor biasing circuits where stable 15 V regulation is required.
For engineers reviewing the BZV90-C15,115 datasheet, BZV90-C15,115 pinout, BZV90-C15,115 application, or BZV90-C15,115 equivalent, key selection criteria 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 with FR4 PCB copper area ≥2 cm².
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ = 13.8–15.6 V range and low dynamic impedance (10–30 Ω) across its specified test current. Its temperature coefficient (−5.0 to +4.0 mV/K) enables predictable drift behavior in ambient-temperature-varying environments.
The device supports high-energy transient suppression via 40 W non-repetitive peak reverse power dissipation (tp = 100 μs), while maintaining 1.5 W continuous power rating on standard FR4 PCBs. Its 75 pF junction capacitance at 0 V reverse bias supports moderate-frequency regulation without significant phase lag.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 13.8 V min / 15.6 V max at IZtest = 5 mA - defines usable regulation window under nominal bias |
| Differential Resistance rdif | 10 Ω typ / 30 Ω max at IZtest = 5 mA - determines output impedance and load regulation error |
| Temperature Coefficient SZ | −5.0 to +4.0 mV/K at IZtest = 5 mA - quantifies voltage drift per °C for thermal design margining |
| Total Power Dissipation Ptot | 1500 mW at Tamb = 25 °C on 2 cm² FR4 copper - sets maximum steady-state thermal load |
| Non-repetitive Peak Power PZSM | 40 W for tp = 100 μs square wave - enables surge protection in line-transient scenarios |
| Junction-to-Ambient Rth j-a | 83.3 K/W - used to calculate ΔTj rise above ambient under given power dissipation |
| Reverse Current IR | ≤0.05 μA at VR = 11.25 V - ensures minimal leakage in high-impedance reference paths |
Pinout & Package
SOT223 plastic surface-mount package with exposed collector pad for enhanced thermal conduction; 4-terminal configuration optimized for power dissipation on double-sided FR4 PCBs with ≥2 cm² copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Main anode connection; referenced to cathode for forward conduction path |
| 2, 4 | Cathode | Parallel cathode terminals; both must be connected to regulated node for full current handling |
| 3 | Anode | Secondary anode terminal; electrically identical to Pin 1, improves mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| E24-standardized Zener voltages | 37 types from 2.4 V to 75 V enable precise matching to common rail requirements |
| ±5% voltage tolerance | Reduces need for post-regulation trimming in cost-sensitive industrial power designs |
| Low differential resistance (10 Ω typ) | Minimizes output voltage shift under load current variation up to 400 mA |
| 40 W non-repetitive peak power | Supports IEC 61000-4-5 surge immunity without external clamping components |
| SOT223 thermal pad layout | Enables direct thermal coupling to PCB copper pour for reliable 1.5 W continuous operation |
Applications
| Industrial Power Supply Regulation | Analog Sensor Bias Reference |

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-C15 | Same 15 V nominal Zener voltage but SOT23 package; 350 mW Ptot; higher rdif (30 Ω typ) | Limited to low-power signal-level references; unsuitable for >100 mA regulation loads | Select when board space is constrained and thermal budget ≤350 mW suffices |
| 1N4744A | Through-hole DO-41; 15 V VZ; 1 W Ptot; 16 Ω rdif; no thermal pad | Requires larger PCB footprint and lacks SOT223's thermal pad for heat spreading | Prefer for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with BZX84-C15 and 1N4744A, BZV90-C15,115 uniquely combines 1.5 W power handling, low 10 Ω rdif, and SOT223 thermal pad-making it optimal for surface-mount industrial power rails needing robust 15 V stabilization without heatsinks.

FAQ
What is the maximum continuous forward current for BZV90-C15,115?
The maximum continuous forward current is 400 mA at Tamb = 25 °C. This rating assumes standard mounting on FR4 PCB with 2 cm² copper area. Exceeding this current risks thermal runaway due to junction temperature exceeding 150 °C, as specified in the Absolute Maximum Ratings table.
How does the temperature coefficient affect regulation accuracy over temperature?
The temperature coefficient ranges from −5.0 to +4.0 mV/K at 5 mA test current. Over a −40 °C to +125 °C junction temperature range, this produces a total VZ shift of approximately ±0.83 V-critical for applications requiring tight regulation across wide ambient conditions.
Can BZV90-C15,115 replace BZX84-C15 in existing SOT23 footprints?
No-it uses SOT223 package with different pin count (4 pins vs. 3) and physical dimensions (6.7 × 3.7 mm vs. 3.0 × 1.4 mm). Direct replacement requires PCB redesign to accommodate larger body size, dual cathode pads, and thermal pad layout.
What is the significance of the dual cathode terminals (Pins 2 and 4)?
Pins 2 and 4 are internally connected cathodes, enabling parallel current sharing and lower effective thermal resistance. Both must be soldered to the same net-typically a large copper pour-to achieve rated 1.5 W power dissipation and avoid localized overheating.
