Product details
Overview
BZV55-C22,115 from Nexperia is a ±5 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 22 V nominal Zener voltage at 5 mA, 60 Ω typical differential resistance, and 500 mW total power dissipation. It serves as a precision low-power voltage reference or shunt regulator in bias networks, overvoltage clamping, and signal-level voltage stabilization circuits.
For engineers reviewing the BZV55-C22,115 datasheet, BZV55-C22,115 pinout, BZV55-C22,115 application, or BZV55-C22,115 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (300 K/W junction-to-solder point), reverse leakage at 15.4 V (≤50 nA), and non-repetitive surge capability (1.25 A peak reverse current).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under controlled current conditions. Its temperature coefficient of +14.1 mV/K at 5 mA enables predictable drift compensation in mid-voltage reference designs.
The SOD80C package provides hermetic sealing for moisture resistance and consistent thermal performance on ceramic substrates. Differential resistance remains below 250 Ω up to 22.4 V, supporting stable regulation in low-current analog monitoring paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 20.8 V to 23.3 V at IZ = 5 mA - defines operating voltage window for shunt regulation |
| Differential Resistance (rdif) | 60 Ω typ. at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Temperature Coefficient (SZ) | +14.1 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius rise |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C on ceramic substrate - sets maximum continuous DC power handling |
| Reverse Leakage Current (IR) | ≤50 nA at VR = 15.4 V - ensures minimal parasitic current in high-impedance bias networks |
| Non-repetitive Peak Reverse Current (IZSM) | 1.25 A for tp = 100 µs - supports transient overvoltage suppression without failure |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - defines conduction threshold in forward-biased protection configurations |
Pinout & Package
Hermetically sealed glass SOD80C surface-mount package: 3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height; cathode marked by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated voltage node; reverse-biased terminal during Zener operation |
| 2 | Anode | Connected to ground or lower-potential reference; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass SMD construction | Eliminates moisture-induced parameter shift and enables long-term stability in humid environments |
| ±5 % Zener voltage tolerance | Supports cost-sensitive applications where tight regulation is secondary to reliability and consistency |
| Low differential resistance (60 Ω typ.) | Minimizes output voltage variation under ±1 mA load current changes in reference circuits |
| Controlled temperature coefficient (+14.1 mV/K) | Enables predictable thermal drift modeling for compensated voltage references |
| Non-repetitive 40 W surge rating | Provides robustness against short-duration transients without requiring external TVS coordination |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C22,115 | Same SOD123 package, identical 22 V ±5 % rating, but higher 80 Ω typical rdif and 350 mW Ptot | Less suitable for precision reference use; better for general-purpose clamping where power density is constrained | Select when board space allows larger SOD123 footprint and thermal budget is limited to 350 mW |
| MMSZ5248B-TP | SOD-123 package, 22 V ±5 %, 30 Ω rdif, but only 350 mW Ptot and no hermetic seal | Higher regulation accuracy but reduced long-term stability in humid or high-reliability environments | Prefer for cost-sensitive consumer electronics where hermeticity is not required and tighter rdif is critical |
Compared with BZV55-C22,115, BZT52-C22,115 trades regulation precision for smaller footprint and lower thermal mass, while MMSZ5248B-TP improves voltage stability at the expense of environmental robustness and surge resilience.

FAQ
What is the maximum continuous power dissipation for BZV55-C22,115 at 70 °C ambient?
At 70 °C ambient, derating applies: Ptot drops linearly from 500 mW at 50 °C to zero at 150 °C junction temperature. With Rth(j-a) = 380 K/W, maximum continuous dissipation is approximately 316 mW - calculated as (150 − 70) °C ÷ 380 K/W = 0.211 W, adjusted for mounting on ceramic substrate per datasheet condition.
Can BZV55-C22,115 be used in series for higher voltage regulation?
No - BZV55-C22,115 lacks matched characteristics for series stacking. Its ±5 % tolerance and variable temperature coefficients cause uneven voltage division and thermal runaway risk. For >22 V references, use single-device solutions like BZV55-C24 or dedicated programmable shunt regulators.
Is the SOD80C package compatible with standard reflow profiles?
Yes - the SOD80C package is qualified for lead-free reflow per J-STD-20. Recommended profile uses peak temperature ≤260 °C for ≤10 seconds, with ramp rates ≤3 °C/s. Footprint dimensions (2.30 × 4.30 mm solder lands) match IPC-7351B generic SOD80C land patterns.
How does the 22 V Zener voltage relate to the marking code on the device?
The "22" in BZV55-C22,115 directly indicates nominal Zener voltage. Devices are marked with "22" on the cathode band side; no additional alphanumeric codes denote tolerance - the "C" in the part number specifies ±5 %, confirmed by datasheet Table 8 and ordering code suffix -115 (tape-and-reel, 2500 pcs).
