Product details
Overview
BZV55-C3V3,135 from Nexperia is a 3.3 V ±5 % Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 500 mW total power dissipation and 40 W non-repetitive peak reverse power, used for low-power voltage reference and regulation in signal conditioning and power rail stabilization circuits.
For engineers reviewing the BZV55-C3V3,135 datasheet, BZV55-C3V3,135 pinout, BZV55-C3V3,135 application, or BZV55-C3V3,135 equivalent, key selection criteria include nominal Zener voltage (3.3 V), tolerance (±5 %), differential resistance (350 Ω typ. at IZ = 5 mA), reverse leakage (5 µA max at VR = 1 V), and thermal resistance (300 K/W junction-to-solder point).
Technical Context
This device operates as a two-terminal silicon Zener diode with sharp reverse breakdown at 3.3 V under regulated current conditions. Its temperature coefficient is −2.4 mV/K (typ.) and differential resistance is 350 Ω (typ.) at 5 mA test current, enabling stable reference performance across moderate temperature and load variations.
The SOD80C package provides hermetic glass sealing for moisture resistance and consistent long-term Zener voltage stability. It supports reflow and wave soldering per JEDEC standards, with thermal resistance from junction to solder point specified at 300 K/W when mounted on a 10 × 10 × 0.6 mm ceramic substrate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.3 V nominal, ±5 % tolerance - defines precise clamping/reference level for 3.3 V rail stabilization |
| Differential Resistance (rdif) | 350 Ω typical at IZ = 5 mA - determines output impedance and regulation sensitivity to current changes |
| Reverse Leakage (IR) | ≤5 µA at VR = 1 V - ensures minimal parasitic loading in high-impedance bias/reference networks |
| Total Power Dissipation (Ptot) | 500 mW maximum at Tamb ≤ 50 °C - sets continuous DC power handling limit in compact PCB layouts |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - enables transient overvoltage suppression without failure |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - defines forward conduction loss when used in bidirectional protection or polarity-sensitive circuits |
| Thermal Resistance (Rth(j-sp)) | 300 K/W junction-to-solder point - quantifies thermal path efficiency for board-level heat extraction |
Pinout & Package
The BZV55-C3V3,135 is housed in a hermetically sealed glass SOD80C surface-mount package (1.60 mm × 3.70 mm × 0.30 mm) with axial leads; the black marking band denotes the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (cathode) | Zener anode connection point | Connected to higher-potential node in reverse-biased regulation; carries full Zener current during clamping |
| 2 (anode) | Zener cathode connection point | Connected to lower-potential reference or ground; establishes polarity for proper reverse-bias operation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass SMD packaging | Ensures long-term parameter stability and moisture immunity in humid or harsh environments |
| Low differential resistance | 350 Ω typical enables tight voltage regulation under varying load currents |
| Controlled ±5 % Zener tolerance | Supports cost-optimized designs where tighter 2 % tolerance is not required |
| High non-repetitive surge capability | 40 W peak power rating allows robust transient suppression without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C3V3 | Same 3.3 V ±5 % rating, but in larger DO-35 glass axial package (not SMD); higher Rth(j-a) (500 K/W) | Requires through-hole assembly and more board area; less suitable for high-density SMT designs | Select when legacy through-hole compatibility or higher surge margin (500 mW Ptot) is prioritized over footprint size |
| MMSZ5226B | 3.3 V ±5 % in SOD-123 package; lower Ptot (350 mW); higher IR (10 µA at 1 V) | Lower power handling and higher leakage reduce suitability for precision reference or high-reliability clamping | Select only for space-constrained consumer-grade applications where 350 mW rating and 10 µA leakage are acceptable |
Compared with BZX55-C3V3 and MMSZ5226B, the BZV55-C3V3,135 uniquely balances SMD compatibility, 500 mW power rating, 5 µA low leakage, and 300 K/W thermal resistance-making it optimal for industrial-grade 3.3 V regulation where board density and thermal reliability are both critical.

FAQ
What is the maximum continuous Zener current for BZV55-C3V3,135 at 25 °C ambient?
The absolute maximum forward current is 250 mA, but continuous Zener operation is limited by power dissipation. At 25 °C ambient and 500 mW Ptot, the maximum steady-state Zener current is approximately 152 mA (500 mW ÷ 3.3 V). Derating applies above 50 °C ambient per the thermal characteristics table.
How does the −2.4 mV/K temperature coefficient affect regulation accuracy over −40 °C to +85 °C?
With a nominal VZ of 3.3 V and −2.4 mV/K TC, the voltage drift over 125 K (−40 °C to +85 °C) is approximately −300 mV. However, this is a typ. value at IZ = 5 mA; actual drift depends on operating current and thermal design. For precision use, maintain stable IZ and minimize self-heating via adequate copper pour.
Can BZV55-C3V3,135 be used in place of a 3.3 V TVS diode for ESD protection?
No-it is not rated or characterized for IEC 61000-4-2 ESD immunity. While it clamps at ~3.3 V, its 40 W non-repetitive surge rating applies only to 100 µs square waves, not the 150 ps rise time of ESD pulses. Dedicated TVS diodes (e.g., PESD3V3X1BL) offer faster response and verified ESD robustness.
What is the significance of the "135" suffix in BZV55-C3V3,135?
The "135" is Nexperia's packing code indicating 10,000 units per reel in 4 mm pitch tape-and-reel format (per Table 10). It does not affect electrical specifications or package dimensions-only packaging configuration and ordering logistics.
