Product details
Overview
BZV90-C24,115 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 24 V at 5 mA test current, with ±5% tolerance, 25 Ω typical differential resistance, and −1.25 mV/K temperature coefficient. Used in industrial power monitoring circuits where stable 24 V regulation under variable load and temperature is required.
For engineers reviewing the BZV90-C24,115 datasheet, BZV90-C24,115 pinout, BZV90-C24,115 application, or BZV90-C24,115 equivalent, key selection criteria include Zener voltage accuracy at IZtest = 5 mA, thermal resistance (83.3 K/W), non-repetitive surge capability (16.8 A peak reverse current), and SOT223 thermal pad layout compatibility.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable output voltage across varying input and load conditions. Its 24 V nominal regulation point falls within the mid-range E24 series, optimized for low-drift performance with a −1.25 mV/K temperature coefficient and 25 Ω differential resistance at 5 mA.
The SOT223 package integrates a large copper collector pad for enhanced thermal dissipation, supporting 1.5 W continuous power dissipation on FR4 PCBs with 2 cm² copper area. Non-repetitive surge handling reaches 40 W for 100 μs pulses, enabling robust transient suppression in regulated supplies.
Key Specifications

| Non-repetitive Peak Reverse Current IZSM | 16.8 A at tp = 100 μs - provides surge immunity against short-duration transients |
| Junction Temperature Tj | 150 °C max - defines maximum allowable silicon operating temperature before thermal shutdown risk |
| Reverse Current IR | 0.05 μA max at VR = 18.8 V - guarantees minimal leakage in high-impedance bias networks |

FAQ
What is the maximum continuous power dissipation for BZV90-C24,115?
The BZV90-C24,115 has a maximum continuous power dissipation of 1500 mW at ambient temperature of 25 °C when mounted on an FR4 PCB with 2 cm² copper area. Derating is required above 25 °C at 12 mW/K, based on its 83.3 K/W junction-to-ambient thermal resistance.
How does the dual-cathode configuration (pins 2 and 4) affect circuit layout?
Pins 2 and 4 are internally connected cathodes, allowing symmetrical PCB routing to reduce parasitic inductance and improve current sharing during surge events. This configuration also enables thermal spreading across two copper pours, lowering effective junction temperature by up to 8 °C under 1 A pulsed load.
Can BZV90-C24,115 replace older BZX85 series diodes in legacy designs?
Yes-BZV90-C24,115 matches the 24 V Zener voltage and ±5% tolerance of BZX85-C24, but offers superior thermal performance (SOT223 vs. DO-35), higher surge rating (16.8 A vs. 2.5 A), and lower differential resistance (25 Ω vs. 35 Ω), making it a drop-in upgrade for reliability-critical revisions.
What is the significance of the −1.25 mV/K temperature coefficient at 5 mA?
This coefficient quantifies how much the Zener voltage decreases per Kelvin rise in junction temperature at 5 mA test current. For example, a 50 K rise from 25 °C to 75 °C causes a −62.5 mV shift, enabling accurate system-level drift budgeting in temperature-controlled enclosures or uncooled industrial environments.
