Product details
Overview
BZX384-C3V6,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 3.6 V nominal breakdown voltage at 5 mA, 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves as a precision low-power reference or clamp in power supply feedback loops, sensor biasing, and overvoltage protection circuits.
For engineers reviewing the BZX384-C3V6,115 datasheet, BZX384-C3V6,115 pinout, BZX384-C3V6,115 application, or BZX384-C3V6,115 equivalent, key selection criteria include its 3.4 V to 3.8 V breakdown range, 90 µA max reverse current at 1 V, 600 Ω max differential resistance, and thermal resistance of 415 K/W junction-to-ambient.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with a nominal 3.6 V regulation voltage at IZ = 5 mA. Its temperature coefficient is −3.5 mV/K, indicating predictable negative drift over temperature, and it exhibits ≤90 µA reverse leakage at 1 V reverse bias.
The device supports pulsed operation up to 40 W for 100 µs pulses and maintains stable regulation under DC loads up to 250 mA forward current. Its SOD323 package enables compact PCB layout while delivering 150 °C maximum junction temperature capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 3.4 V to 3.8 V at IZ = 5 mA - defines usable regulation window for 3.3 V system references |
| Total Power Dissipation Ptot | 300 mW at Tamb ≤ 25 °C - limits continuous DC load in FR4 PCB mounting |
| Differential Resistance rdif | ≤600 Ω - determines output impedance and regulation sensitivity to current changes |
| Reverse Current IR | ≤90 µA at VR = 1 V - ensures low quiescent leakage in high-impedance bias networks |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - enables use as low-drop rectifier or clamping element |
| Non-repetitive Peak Power | 40 W for tp = 100 µs - supports transient surge suppression in ESD-critical nodes |
| Junction-to-Ambient Rth(j-a) | 415 K/W - sets thermal rise per watt on standard FR4 board, critical for derating |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | 3.3 V nominal, ±5 %, SOT-23 package, 225 mW rating | Lower power and voltage; requires larger board area and different footprint | Select when legacy SOT-23 layout exists and 3.3 V reference suffices |
| BZX384-B3V6,115 | 3.6 V nominal, ±2 % tolerance, identical SOD323 package and 300 mW rating | Tighter regulation needed for precision ADC reference buffers | Choose for improved stability where ±2 % VZ variation is required over process/temperature |

FAQ
What is the guaranteed breakdown voltage range for BZX384-C3V6,115?
The guaranteed breakdown voltage is 3.4 V minimum to 3.8 V maximum at test current IZ = 5 mA, per Nexperia's Rev. 4 datasheet Table 8. This ±5 % tolerance band reflects the 'C' grade designation and applies across the full operating temperature range of −65 °C to +150 °C.
Can BZX384-C3V6,115 be used in series or parallel configurations?
No-this Zener is designed strictly for single-device shunt regulation. Parallel connection causes current imbalance due to VZ mismatch, and series stacking introduces cumulative tolerance and thermal coupling issues. For higher voltage references, select a dedicated higher-VZ part from the same series.
How does thermal resistance affect derating at elevated ambient temperatures?
With Rth(j-a) = 415 K/W, power must be linearly derated above 25 °C ambient: Pderated = 300 mW × (1 − (Tamb − 25)/125). At 85 °C ambient, maximum allowable dissipation drops to 144 mW to maintain Tj ≤ 150 °C.
Is BZX384-C3V6,115 qualified for automotive applications?
No-this part is non-automotive qualified per Nexperia's Rev. 4 datasheet revision history. Automotive-grade alternatives (e.g., BZX384-Q series) undergo AEC-Q200 stress testing and are explicitly marked with '-Q' suffix; BZX384-C3V6,115 is intended for industrial and consumer use only.
