Product details
Overview
BZV90-C3V3,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and regulation at 3.3 V nominal working voltage (±5%), with 85 Ω typical differential resistance at 5 mA test current, 1.5 W total power dissipation, and −2.4 mV/K temperature coefficient. It serves in low-voltage power supply feedback paths and voltage clamping circuits.
For engineers reviewing the BZV90-C3V3,115 datasheet, BZV90-C3V3,115 pinout, BZV90-C3V3,115 application, or BZV90-C3V3,115 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (83.3 K/W), non-repetitive peak reverse power (40 W), junction temperature limit (150 °C), and SOT223 thermal pad layout compatibility.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ = 3.1–3.5 V at IZtest = 5 mA, exhibiting low dynamic impedance (85–95 Ω) and negative temperature coefficient (−2.4 mV/K), enabling stable low-voltage regulation under varying thermal conditions. Its SOT223 package integrates a large copper collector pad for enhanced heat dissipation.
The device supports surge handling up to 40 W for 100 μs pulses and maintains reverse leakage ≤5 μA at VR = 3 V. Electrical behavior is characterized across −65 °C to +150 °C storage and operating junction temperatures, with forward voltage ≤1.0 V at 50 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.1–3.5 V at 5 mA - defines precise regulation point for 3.3 V nominal rail |
| Differential Resistance (rdif) | 85–95 Ω at 5 mA - determines load regulation error under current variation |
| Temperature Coefficient (SZ) | −2.4 mV/K - enables predictable drift compensation in temperature-sensitive designs |
| Total Power Dissipation (Ptot) | 1500 mW at Tamb = 25 °C on 2 cm² FR4 PCB - sets continuous thermal design boundary |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 μs - supports transient overvoltage suppression without failure |
| Junction Temperature (Tj) | 150 °C maximum - constrains PCB layout and heatsinking for long-term reliability |
| Reverse Leakage (IR) | ≤5 μA at VR = 3 V - ensures minimal quiescent current in standby regulation |
Pinout & Package
SOT223 plastic surface-mount package with integrated thermal pad (lead 2 and 4 are cathode; lead 1 and 3 are anode). The 4-lead configuration enables dual-anode routing and improved thermal transfer via exposed collector pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; electrically identical to pin 3; used for dual-anode PCB routing |
| 2 | Cathode | Main cathode terminal; bonded to internal Zener junction; connects to regulated output node |
| 3 | Anode | Secondary anode; redundant path for mechanical robustness and thermal symmetry |
| 4 | Cathode | Second cathode terminal; shares internal node with pin 2; improves current sharing and solder joint reliability |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance (E24 range) | Enables direct replacement in legacy 3.3 V reference designs without recalibration |
| 1500 mW continuous power rating | Supports higher-current regulation than standard DO-35 or SOD-123 Zeners |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4678T1G | VZ = 3.3 V (±5%), SOD-123 package, Ptot = 500 mW, rdif = 95 Ω | Lower power rating limits use in >150 mA regulation; no thermal pad | Select when board space is constrained and thermal load is <0.5 W |
| BZX84-C3V3 | VZ = 3.3 V (±5%), SOT-23 package, Ptot = 300 mW, rdif = 90 Ω | Smaller footprint but higher thermal resistance (350 K/W); unsuitable for >100 mA continuous | Choose for cost-sensitive consumer PCBs where power is <0.3 W |
Compared with MMSZ4678T1G and BZX84-C3V3, BZV90-C3V3,115 delivers 3× higher continuous power and 4× lower thermal resistance-making it the only option among the three viable for industrial 12 V-to-3.3 V linear post-regulation with >300 mA load current.

FAQ
What is the maximum continuous reverse current this Zener can handle at 3.3 V regulation?
The BZV90-C3V3,115 supports a maximum continuous reverse current of 400 mA, derived from its 1500 mW power rating and 3.3 V nominal Zener voltage (P = V × I → I = 1500 mW / 3.3 V ≈ 455 mA, limited to 400 mA per Absolute Maximum Ratings table). This enables use in moderate-current shunt regulators.
Does this device require a heatsink for 1 W continuous operation?
No heatsink is required for 1 W continuous operation if mounted on a standard FR4 PCB with ≥2 cm² double-sided copper area, as its thermal resistance from junction to ambient is specified at 83.3 K/W. At 1 W, junction-to-ambient temperature rise is ~83 °C, keeping Tj within 150 °C limit at Tamb ≤ 67 °C.
Can BZV90-C3V3,115 be used in place of BZX84-C3V3 in existing designs?
Direct substitution is not recommended without layout revision: BZV90-C3V3,115 uses SOT223 (6.7 × 3.7 mm) versus SOT-23 (3.0 × 1.4 mm), requiring footprint change and thermal pad rework. Electrical parameters are compatible, but thermal performance and mounting mechanics differ significantly.
What is the typical capacitance at zero bias, and how does it affect high-frequency noise filtering?
Diode capacitance is 450 pF at f = 1 MHz and VR = 0 V. This value makes the device effective for low-MHz noise suppression in power rails but unsuitable for RF bypassing above ~10 MHz, where lower-capacitance Zeners (e.g., <50 pF) are preferred to avoid resonance with parasitic inductance.
