Product details
Overview
BZV55-B22,115 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 circuits. It delivers a nominal 22 V Zener voltage with ±2 % tolerance (B-series), 60 Ω typical differential resistance at IZ = 5 mA, and a temperature coefficient of +14.1 mV/K at 22 V, enabling stable biasing in analog sensor interfaces and power supply feedback networks.
For engineers reviewing the BZV55-B22,115 datasheet, BZV55-B22,115 pinout, BZV55-B22,115 application, or BZV55-B22,115 equivalent, this device serves as a compact, thermally robust voltage reference for space-constrained industrial control modules, automotive body electronics, and portable instrumentation where tight voltage accuracy and low leakage (<100 nA at 0.7×VZ) are required.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its cathode–anode terminals under controlled current conditions. Its 22 V nominal Zener voltage is specified at IZ = 5 mA, with a low 60 Ω typical dynamic resistance ensuring minimal voltage shift with load variation.
The device exhibits a positive temperature coefficient of +14.1 mV/K, indicating predictable voltage drift with junction temperature rise-critical for thermal compensation design in precision references. Its SOD80C package provides hermetic sealing and a thermal resistance of 300 K/W from junction to solder point, supporting reliable operation up to 200 °C storage temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 21.6 V to 22.4 V at IZ = 5 mA - defines precise regulation point for feedback or reference circuits |
| Differential Resistance (rdif) | 60 Ω typ. at IZ = 5 mA - ensures <130 mV output shift per 2 mA current change |
| Temperature Coefficient (SZ) | +14.1 mV/K at IZ = 5 mA - enables predictable thermal drift modeling in reference designs |
| Reverse Leakage (IR) | <100 nA at VR = 15.4 V (0.7×VZ) - minimizes error current in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C - supports continuous operation in ambient temperatures up to 50 °C without derating |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 μs - allows transient surge handling in ESD-protected input stages |
| Package | SOD80C - hermetically sealed glass SMD package with 3.3–3.7 mm length and 1.45–1.60 mm width |
Pinout & Package

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C22 (ON Semiconductor) | ±5 % tolerance, 600 mW Ptot, higher 120 Ω rdif, DO-35 through-hole package | Lower cost but less accurate; requires board real estate for axial lead mounting | Select when ±5 % regulation suffices and through-hole assembly is preferred |
| MMSZ5247B (Diodes Inc.) | ±5 % tolerance, SOD-123 package, 500 mW Ptot, 30 Ω rdif at 20 mA | Lower dynamic resistance but looser tolerance; plastic package lacks hermetic seal | Select for improved regulation stiffness where environmental sealing is not required |

FAQ
What is the maximum continuous forward current for BZV55-B22,115?
The BZV55-B22,115 is rated for a maximum forward current (IF) of 250 mA per Absolute Maximum Ratings. However, it is operated in reverse breakdown for regulation; forward conduction is only relevant during circuit power-up sequencing or fault conditions-not during normal Zener function.
Does BZV55-B22,115 require a series current-limiting resistor in all applications?
Yes-this Zener diode must be used with an external series resistor to set the operating current (typically 5 mA) and prevent thermal runaway. The resistor value is calculated as R = (VIN − VZ) / IZ, where VIN is the unregulated supply and IZ is chosen based on desired regulation stiffness and power dissipation limits.
Can BZV55-B22,115 be used in parallel for higher power handling?
No-Zener diodes should never be paralleled due to mismatched breakdown voltages causing current hogging and thermal failure. For higher power needs, use a single higher-rated Zener or switch to an active shunt regulator topology with external pass transistor and feedback control.
Is the SOD80C package compatible with standard reflow soldering profiles?
Yes-the SOD80C package is qualified for lead-free reflow soldering per J-STD-020. Recommended peak temperature is 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s. The glass body withstands thermal shock better than plastic packages, reducing risk of cracking during profile transitions.
