Product details
Overview
BZV55-B22,135 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 22 V nominal working voltage with ±2 % tolerance, 60 Ω typical differential resistance at IZ = 5 mA, and 200 mW total power dissipation at Tamb ≤ 50 °C. It provides stable reference voltage in low-current bias networks for analog sensor signal conditioning circuits.
For engineers reviewing the BZV55-B22,135 datasheet, BZV55-B22,135 pinout, BZV55-B22,135 application, or BZV55-B22,135 equivalent, this page delivers verified electrical parameters, thermal behavior under transient surge, cathode/anode terminal mapping, and direct-fit alternatives for precision voltage reference design.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 22 V reference across its terminals when biased with ≥5 mA current. Its temperature coefficient of +14.1 mV/K (typical) ensures predictable drift over operating range, and low 60 Ω differential resistance minimizes output impedance variation under load changes.
Designed for use in free-air or ceramic substrate mounting (10 × 10 × 0.6 mm), it supports non-repetitive peak reverse power dissipation up to 40 W for 100 µs pulses, with junction-to-ambient thermal resistance of 380 K/W and junction-to-solder-point resistance of 300 K/W.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C22,113 | ±5 % tolerance, higher 100 Ω typical rdif, same SOD80C package | Acceptable where cost sensitivity outweighs precision requirements | Select for cost-driven consumer-grade power rails where ±2 % is not required |
| MMSZ5248B-7-F | ±5 % tolerance, 350 mW Ptot, SOD-123 package (larger footprint) | Higher power handling but incompatible with high-density SOD80C layouts | Choose only if board space allows larger package and 350 mW dissipation is needed |
Compared with BZV55-B22,135, the BZX55C22,113 trades precision for cost in identical form factor, while MMSZ5248B-7-F offers higher power at the expense of PCB area and thermal coupling-neither matches the 22 V ±2 %/60 Ω combination in SOD80C.

FAQ
What is the maximum continuous reverse current for reliable Zener operation?
The device is rated for 5 mA nominal Zener test current, with absolute maximum forward current of 250 mA. Continuous reverse current must remain within derated power limits: at 25 °C ambient, sustained operation above ~9 mA exceeds 200 mW dissipation and risks thermal runaway without heatsinking.
How does temperature affect the 22 V regulation voltage?
At IZ = 5 mA, the temperature coefficient is +14.1 mV/K (typical), meaning the Zener voltage increases by ~14.1 mV per °C rise. Over –40 °C to +125 °C, this produces a total shift of approximately ±2.3 V from nominal 22 V, confirmed in Figure 4 of the datasheet.
Can BZV55-B22,135 be used in series for higher voltage references?
Yes-multiple units may be stacked anode-to-cathode to achieve higher reference voltages, but cumulative tolerance (±2 % each) and mismatched temperature coefficients will degrade overall accuracy; parallel connection is not recommended due to current-sharing instability.
Is the SOD80C package compatible with standard reflow profiles?
Yes-the SOD80C outline meets JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260 °C, 30 s max). Figure 7 provides the recommended solder land pattern (2.30 mm × 4.30 mm) for optimal thermal and mechanical reliability.
