Product details

Overview

BZV55-C33,135 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 33 V nominal working voltage at 5 mA test current, 45 Ω typical differential resistance, and 0.9 V forward voltage at 10 mA. It delivers stable reference voltage in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.

For engineers reviewing the BZV55-C33,135 datasheet, BZV55-C33,135 pinout, BZV55-C33,135 application, or BZV55-C33,135 equivalent, key selection criteria include its 33 V Zener voltage tolerance (±5 %), 45 Ω differential resistance at I_Z = 5 mA, 500 mW total power dissipation, and SOD80C thermal resistance of 300 K/W to solder point.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable 33 V reference across load variations, with temperature coefficient of +23.3 mV/K at I_Z = 2 mA. Its low 45 Ω differential resistance ensures minimal output voltage drift under dynamic current changes.

The device uses a planar silicon junction structure housed in a hermetically sealed glass SOD80C package, enabling reliable operation up to 200 °C storage temperature and supporting reflow/wave soldering per JEDEC standards.

Differential resistance r_dif	75 Ω max at I_Z = 2 mA - determines output impedance and load regulation error
Temperature coefficient S_Z	+23.3 mV/K typ at I_Z = 2 mA - quantifies voltage drift per degree Celsius change
Total power dissipation P_tot	500 mW max at T_amb ≤ 50 °C on ceramic substrate - sets maximum continuous DC power handling
Non-repetitive peak reverse power	40 W for 100 μs square wave - supports transient overvoltage clamping
Forward voltage V_F	0.9 V max at I_F = 10 mA - defines conduction loss when used in forward-biased protection
Reverse leakage I_R	50 nA max at V_R = 0.7 × V_Z(nom) - ensures low standby current in high-impedance bias networks

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-C33	Same 33 V rating and ±5 % tolerance, but in larger DO-35 glass axial package (not SMD)	Requires through-hole assembly; higher thermal resistance (500 K/W vs 300 K/W)	Select for prototyping or legacy board compatibility where SMT is not required
MMSZ5260B	33 V, ±5 %, SOD-123 package; 90 Ω max r_dif vs 75 Ω max for BZV55-C33	Higher dynamic impedance reduces regulation accuracy under varying load	Select when footprint compatibility with SOD-123 is mandatory and tighter regulation is not critical

Compared with BZX55-C33 and MMSZ5260B, BZV55-C33,135 offers superior thermal performance in SMT form factor and lower differential resistance-critical for stable feedback in compact power converters.

FAQ

What is the maximum continuous power dissipation for BZV55-C33,135?

The BZV55-C33,135 has a maximum total power dissipation of 500 mW when mounted on a 10 × 10 × 0.6 mm ceramic substrate at ambient temperatures ≤50 °C. Derating is required above this temperature, following the specified thermal resistance of 300 K/W to solder point.

How does the temperature coefficient affect regulation accuracy over temperature?

With a typical temperature coefficient of +23.3 mV/K at I_Z = 2 mA, the BZV55-C33,135 exhibits a +0.07 %/°C drift in Zener voltage. Over a −40 °C to +85 °C range, this results in approximately ±2.9 V shift from nominal 33 V, requiring compensation in high-accuracy systems.

Can BZV55-C33,135 be used in parallel for higher power handling?

No-Zener diodes must not be paralleled without individual ballast resistors due to mismatched breakdown voltages. Even within ±5 % tolerance, unit-to-unit V_Z variation causes current hogging and thermal runaway. Use a single higher-power device or active regulation instead.

What is the reverse leakage current at 23 V bias?

At V_R = 23 V (≈0.7 × 33 V), the reverse leakage current is guaranteed ≤50 nA per datasheet Table 7. This ultra-low leakage enables use in high-impedance bias networks and battery-powered monitoring circuits without significant standby drain.
