Product details
Overview
BZV90-C5V1,135 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 delivers nominal 5.1 V regulation at 5 mA test current, with ±5% tolerance, 40 Ω typical differential resistance, −0.8 mV/K temperature coefficient, and 1500 mW total power dissipation.
For engineers reviewing the BZV90-C5V1,135 datasheet, BZV90-C5V1,135 pinout, BZV90-C5V1,135 application, or BZV90-C5V1,135 equivalent, key selection criteria include Zener voltage stability under varying load/temperature, thermal resistance (83.3 K/W), peak surge capability (40 W, 100 μs), and SOT223 thermal pad suitability for industrial power rail conditioning.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable output voltage across variable input and load conditions. Its low dynamic impedance (40 Ω max at 5 mA) ensures minimal voltage deviation under current transients, while the negative temperature coefficient (−0.8 mV/K) enables predictable drift compensation in multi-diode references.
The SOT223 package integrates an exposed collector pad for enhanced thermal conduction, supporting continuous 400 mA forward current and enabling reliable operation up to 150 °C junction temperature. Non-repetitive peak reverse power handling (40 W, 100 μs) allows robust transient suppression in switching regulator feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.8 V to 5.4 V at 5 mA - defines regulated output range for feedback sensing in 5 V SMPS designs |
| Differential Resistance (rdif) | 40 Ω max at 5 mA - determines output voltage variation under ±10 mA load change (±0.4 V) |
| Temperature Coefficient (SZ) | −0.8 mV/K typical - enables predictable voltage drift compensation in temperature-critical references |
| Total Power Dissipation (Ptot) | 1500 mW at 25 °C ambient on 2 cm² FR4 PCB - sets maximum continuous power handling in compact layouts |
| Thermal Resistance (Rth j-a) | 83.3 K/W - defines junction-to-ambient rise per watt; critical for derating above 25 °C ambient |
| Reverse Current (IR) | 2 μA max at 3.0 V - ensures low leakage in high-impedance bias networks and precision references |
| Non-repetitive Peak Power (PZSM) | 40 W at 100 μs square wave - supports surge immunity during startup or fault events in power supplies |
Pinout & Package
SOT223 plastic surface-mount package with exposed thermal pad (lead 3), optimized for heat transfer in medium-power regulation applications. Dimensions: 6.7 × 3.7 × 1.8 mm (L × W × H), 4-terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; used for forward biasing or cathode-referenced Zener configurations |
| 2, 4 | Cathode | Parallel cathode terminals; provide low-inductance, high-current return path to ground or reference node |
| 3 | Anode (thermal pad) | Exposed copper pad tied to anode; improves thermal dissipation but electrically identical to Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| E24 voltage series coverage | 37 types from 2.4 V to 75 V - enables precise matching to standard power rail voltages without custom design |
| ±5% tolerance grade | Tight initial accuracy reduces need for post-production trimming in cost-sensitive consumer power supplies |
| 1500 mW power rating | Supports higher-current shunt regulation than standard DO-35 or SOD-123 Zeners, eliminating external pass devices |
| Low thermal resistance (83.3 K/W) | Enables stable operation at elevated ambient temperatures (e.g., inside enclosed industrial enclosures) |
| 40 W non-repetitive surge rating | Withstands inrush and transient overvoltage events common in AC/DC adapter and DC-DC converter outputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1 | SOT23 package, 350 mW Ptot, 60 Ω rdif, same VZ range | Limited to low-power signal-level references; unsuitable for >100 mA shunt loads | Select when board space is constrained and thermal budget < 0.35 W; avoid in power supply feedback paths |
| MMSZ5231B | SOD-123 package, 500 mW Ptot, 17 Ω rdif, tighter ±5% tolerance | Better regulation accuracy but lower surge capability (25 W); no thermal pad | Prefer for precision analog references where thermal stress is low and dynamic impedance is critical |
Compared with BZV90-C5V1,135, BZX84-C5V1 trades power handling and thermal performance for miniaturization, while MMSZ5231B offers lower impedance at reduced surge resilience-making the BZV90 optimal for industrial power regulation where reliability under thermal and transient stress is prioritized.

FAQ
What is the maximum continuous Zener current for BZV90-C5V1,135 at 70 °C ambient?
At 70 °C ambient, derating applies per Rth j-a = 83.3 K/W. With Tj max = 150 °C, allowable ΔT = 80 K, so max continuous power = 80 K ÷ 83.3 K/W ≈ 0.96 W. At 5.1 V, this supports ~188 mA continuous Zener current - well within the 400 mA absolute maximum forward rating.
Can BZV90-C5V1,135 be used in parallel for higher current capability?
No - Zener diodes exhibit negative temperature coefficients and manufacturing spread, causing current hogging when paralleled. Even matched units risk thermal runaway due to unequal rdif and self-heating. Use a single higher-power device or active regulation instead.
Is the SOT223 thermal pad (Pin 3) electrically isolated?
No - Pin 3 is internally connected to Pin 1 (anode). The exposed pad serves only for thermal conduction and must be soldered to a copper pour tied to the anode net. Floating or grounding the pad creates a short circuit or compromises thermal performance.
How does the −0.8 mV/K temperature coefficient affect long-term voltage stability?
A −0.8 mV/K coefficient means VZ decreases by 0.8 mV per Kelvin rise. Over a 100 K range (−25 °C to +75 °C), total drift is ~80 mV (1.6% of 5.1 V). This is acceptable for most industrial power rails but requires compensation in metrology-grade references.
