Product details

Overview

BZV55-C4V7,135 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 4.7 V nominal Zener voltage at 5 mA, with 425 Ω typical differential resistance and −1.4 mV/K temperature coefficient. It delivers stable reference voltage in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.

For engineers reviewing the BZV55-C4V7,135 datasheet, BZV55-C4V7,135 pinout, BZV55-C4V7,135 application, or BZV55-C4V7,135 equivalent, this page provides verified electrical parameters, thermal behavior under surge conditions, SOD80C footprint compatibility, and real-world use cases in precision biasing and voltage clamping.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable 4.7 V reference across load variations and temperature shifts. Its −1.4 mV/K temperature coefficient ensures minimal drift over −65 °C to +200 °C junction range, and its 425 Ω differential resistance supports regulation accuracy within ±5 % tolerance at I_Z = 5 mA.

The device handles non-repetitive peak reverse power up to 40 W (100 µs square wave), with total power dissipation limited to 500 mW on a ceramic substrate. Its 300 pF capacitance at 1 MHz and 0.9 V forward voltage at 10 mA support dual-mode operation in both regulation and rectification roles.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	4.4 V to 5.0 V at I_Z = 5 mA - defines usable regulation band for ±5 % tolerance grade
Differential Resistance (r_dif)	425 Ω typ. at I_Z = 5 mA - determines output impedance and load regulation error
Temperature Coefficient (S_Z)	−1.4 mV/K - quantifies voltage drift per degree Celsius, enabling thermal stability analysis
Reverse Current (I_R)	≤3 µA at V_R = 2 V - confirms low leakage in standby or high-impedance sensing nodes
Non-repetitive Peak Power (P_ZSM)	40 W for 100 µs - specifies transient surge handling capability in overvoltage clamp circuits
Total Power Dissipation (P_tot)	500 mW at T_amb ≤ 50 °C on ceramic substrate - sets continuous thermal design limit
Junction-to-Ambient R_th	380 K/W in free air - enables thermal rise estimation without heatsinking

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBZ5225BS-7-F	4.6 V nominal, ±5 %, SOT-23 package, 225 mW P_tot, 600 Ω r_dif	Lower power rating and higher impedance reduce regulation accuracy in >2 mA loads	Prefer for space-constrained PCBs where 225 mW suffices and SOT-23 footprint is required
BZX55-C4V7	Same 4.7 V ±5 % spec, but in larger DO-35 axial package, 500 mW P_tot, 450 Ω r_dif	Through-hole mounting limits automated assembly; higher thermal mass slows transient response	Choose when manual prototyping or legacy through-hole designs require identical electrical behavior

Compared with BZV55-C4V7,135, MMBZ5225BS-7-F trades power and regulation fidelity for smaller size, while BZX55-C4V7 retains identical specs but sacrifices SMD manufacturability for mechanical robustness and thermal inertia.

FAQ

What is the maximum continuous Zener current for BZV55-C4V7,135?

The device supports up to 250 mA forward current, but Zener operation is specified at I_Z = 5 mA for V_Z and r_dif. Continuous Zener current must be limited by power dissipation: at 4.7 V, max I_Z ≈ 106 mA for 500 mW, though derating is required above 50 °C ambient per thermal resistance data.

How does the −1.4 mV/K temperature coefficient affect circuit accuracy over temperature?

At 4.7 V nominal, a −1.4 mV/K coefficient yields ~−0.1 V drift over a 70 °C rise (e.g., 25 °C to 95 °C), corresponding to ~2.1 % relative change. This is acceptable for non-precision references but requires compensation in high-accuracy systems.

Can BZV55-C4V7,135 be used in forward conduction mode?

Yes - it exhibits 0.9 V forward voltage at 10 mA, making it suitable for low-current level-shifting or LED biasing. However, its 250 mA absolute maximum forward current and 500 mW power limit constrain sustained forward operation.

Is the SOD80C package compatible with standard reflow soldering profiles?

Yes - Nexperia specifies compatibility with JEDEC J-STD-020 reflow profiles. The recommended footprint (2.30 mm × 4.30 mm solder lands) and thermal resistance data confirm suitability for lead-free reflow processes with peak temperatures up to 260 °C.
