Product details
Overview
BZV55-C2V7,135 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, designed for precision voltage reference and regulation in low-current analog circuits. It provides a nominal 2.7 V Zener voltage with ±5 % tolerance, 300 Ω typical differential resistance at 5 mA, −3.5 to −2.0 mV/K temperature coefficient, and supports up to 400 mW total power dissipation at ≤50 °C ambient - commonly used in sensor biasing, ADC reference stabilization, and microcontroller reset circuitry.
For engineers reviewing the BZV55-C2V7,135 datasheet, BZV55-C2V7,135 pinout, BZV55-C2V7,135 application, or BZV55-C2V7,135 equivalent, key selection criteria include its 2.7 V nominal Zener voltage, ±5 % tolerance band, SOD80C package thermal resistance (Rth(j-a) = 380 K/W), reverse leakage current of ≤20 µA at 1 V, and non-repetitive peak reverse power capability of 40 W.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its negative temperature coefficient (−3.5 to −2.0 mV/K) ensures predictable drift behavior, while low differential resistance (300–600 Ω) minimizes output impedance variation with current.
The device is rated for 400 mW continuous power dissipation at ambient temperatures ≤50 °C and withstands non-repetitive 100 µs square-wave surges up to 40 W. It uses a hermetically sealed glass SOD80C package optimized for reliability in low-power signal conditioning applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V nominal, ±5 % tolerance (2.5 V to 2.9 V range) - defines stable regulation point for low-voltage references |
| Differential Resistance (rdif) | 300 Ω typical at IZ = 5 mA - determines output impedance and regulation sensitivity to current changes |
| Temperature Coefficient (SZ) | −3.5 to −2.0 mV/K - quantifies voltage drift per degree Celsius, critical for temperature-stable bias networks |
| Reverse Leakage Current (IR) | ≤20 µA at VR = 1 V - limits parasitic loading in high-impedance reference paths |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤50 °C - sets maximum continuous operating power before thermal derating applies |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - enables transient overvoltage clamping without failure |
| Package Thermal Resistance (Rth(j-a)) | 380 K/W in free air - governs junction temperature rise under steady-state operation |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZV55-B2V7,115 | ±2 % tolerance (2.65–2.75 V), lower differential resistance (300 Ω vs. 600 Ω max), same SOD80C package | Higher accuracy required in precision instrumentation; tighter thermal drift spec | Select when reference stability <±0.1 % is mandatory and cost premium is acceptable |

FAQ
What is the maximum continuous forward current for BZV55-C2V7,135?
The device is not intended for forward conduction; its absolute maximum forward current is 250 mA per datasheet limiting values, but sustained forward operation exceeds design intent. Forward voltage is specified only at 10 mA (≤0.9 V), and prolonged forward bias risks degradation of Zener characteristics.
Can BZV55-C2V7,135 be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing spread in breakdown voltage, causing current hogging in parallel configurations. Even matched units show thermal runaway risk due to negative temperature coefficient; external ballast resistors or dedicated regulators are required for >400 mW applications.
How does ambient temperature affect its Zener voltage accuracy?
At 25 °C, VZ is within ±5 % of 2.7 V; over −65 to +200 °C junction range, voltage drift follows −3.5 to −2.0 mV/K. For example, at 75 °C junction temperature, expected shift is −100 to −150 mV relative to 25 °C baseline, requiring system-level compensation if sub-1 % accuracy is needed.
Is this part suitable for automotive applications?
No - BZV55-C2V7,135 is not AEC-Q200 qualified and lacks automotive-grade screening, traceability, or extended temperature validation. Nexperia explicitly states non-automotive qualification in the datasheet; use only in industrial, consumer, or commercial equipment where automotive reliability standards do not apply.
