Product details
Overview
BZV90-C27,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and regulation in power supply feedback paths. It provides a nominal 27 V working voltage at 2 mA test current, with ±5% tolerance, 25 Ω typical differential resistance, and −1.0 mV/K temperature coefficient at IZ = 2 mA. Used in industrial SMPS feedback loops requiring stable 27 V reference under 1.5 W continuous dissipation.
For engineers reviewing the BZV90-C27,115 datasheet, BZV90-C27,115 pinout, BZV90-C27,115 application, or BZV90-C27,115 equivalent, key selection criteria include Zener voltage accuracy at 2 mA, thermal resistance (83.3 K/W), non-repetitive surge capability (18.9 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 load and line conditions. Its 27 V nominal Zener voltage is specified at IZtest = 2 mA, with differential resistance of 25 Ω (typ) ensuring low dynamic impedance for tight regulation.
Designed for surface-mount use on FR4 PCBs with ≥2 cm² copper area, it delivers 1.5 W continuous power dissipation and withstands 40 W non-repetitive peak reverse power for 100 μs pulses - critical for transient suppression in regulated DC rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 25.0 V to 28.9 V at IZ = 2 mA - defines regulation setpoint with ±5% tolerance for stable reference generation |
| Differential Resistance rdif | 25 Ω (typ) at IZ = 2 mA - determines output impedance and load regulation sensitivity |
| Temperature Coefficient SZ | −1.0 mV/K at IZ = 2 mA - enables predictable drift compensation in temperature-varying environments |
| Total Power Dissipation Ptot | 1500 mW at Tamb = 25 °C - sets maximum steady-state thermal load on PCB copper area |
| Non-repetitive Peak Reverse Current IZSM | 18.9 A at tp = 100 μs - supports surge immunity in power supply startup or fault events |
| Junction Temperature Tj | 150 °C max - constrains operating margin when mounted on standard FR4 with 2 cm² copper |
| Reverse Current IR | 0.05 μA max at VR = 20.8 V - ensures minimal leakage in high-impedance bias networks |

FAQ
What is the recommended PCB layout for thermal performance?
Mount BZV90-C27,115 on FR4 with ≥2 cm² double-sided copper area connected to Pins 2 and 4 (cathode) and the exposed thermal pad. Use multiple thermal vias under the pad to inner ground planes. This achieves the rated 83.3 K/W junction-to-ambient thermal resistance and supports full 1.5 W continuous dissipation.
Does this Zener diode require a series current-limiting resistor in shunt regulation?
Yes - a series resistor is mandatory to limit forward current during normal operation and ensure stable reverse-bias operation. For 27 V regulation at 2 mA test current, calculate RS = (VIN − 27 V)/2 mA, selecting standard value with ≥0.5 W rating to handle worst-case power dissipation.
How does temperature affect its Zener voltage in real-world operation?
At IZ = 2 mA, the temperature coefficient is −1.0 mV/K, meaning VZ decreases by ~1 mV per Kelvin rise. Over −40 °C to +105 °C, total drift is approximately −145 mV - verified in Fig.4/5 of the datasheet and critical for high-accuracy references.
Can it be used in parallel for higher current handling?
No - Zener diodes exhibit manufacturing spread in VZ and rdif, causing current imbalance. Parallel connection risks thermal runaway. For higher current, use a single higher-power device or active regulation with a pass transistor driven by this Zener reference.
