Product details
Overview
BZX84-C22,215 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 22 V nominal breakdown voltage at 5 mA, 250 mW total power dissipation, and 150 °C maximum junction temperature - used for precision low-power voltage reference and overvoltage protection in power supply feedback loops and sensor biasing circuits.
For engineers reviewing the BZX84-C22,215 datasheet, BZX84-C22,215 pinout, BZX84-C22,215 application, or BZX84-C22,215 equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (250 Ω max), reverse current (≤0.1 μA at 17.6 V), thermal resistance (500 K/W junction-to-ambient), and non-repetitive peak reverse power (40 W).
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable output voltage across a load by conducting reverse current when input exceeds its 22 V Zener voltage. It exhibits a positive temperature coefficient of +15.4 mV/K at IZ = 5 mA and 25 °C, with typical diode capacitance of 20 pF at 0 V.
The SOT23 package enables surface-mount integration into space-constrained PCBs, with thermal performance defined for FR4 boards having single-sided 70 µm copper. Its non-repetitive surge capability supports transient suppression up to 100 µs pulses at 40 W, limited by junction temperature rise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 20.8 V to 23.3 V at IZ = 5 mA - defines regulated output range under nominal bias |
| Differential Resistance (rdif) | 250 Ω max at IZ = 5 mA - determines regulation stiffness and output impedance |
| Reverse Current (IR) | ≤0.1 μA at VR = 17.6 V - ensures minimal leakage below regulation threshold |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets continuous DC power handling limit |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 μs - supports short-duration surge clamping without failure |
| Junction Temperature (Tj) | −55 °C to +150 °C - defines operational and storage thermal envelope |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - relevant for forward-biased protection or polarity detection |
Pinout & Package
Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with standard footprint per Figure 12 (reflow) and Figure 13 (wave soldering); dimensions per Figure 11.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential node; reverse-biased during regulation |
| 2 | Not Connected (n.c.) | Internal die pad not electrically bonded - no PCB trace required |
| 3 | Cathode (K) | Connected to higher-potential node; carries reverse current during regulation |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5247BS-7-F | 22 V ±5 %, 350 mW Ptot, 200 Ω rdif, SOT23 package | Higher power rating allows greater current margin in feedback paths | Select when >250 mW continuous dissipation or lower dynamic impedance is required |
| Vishay BZX84-C22-TP | 22 V ±5 %, 300 mW Ptot, 250 Ω rdif, same SOT23 footprint | Enhanced surge rating (50 W vs. 40 W) and tighter IR spec (≤0.05 μA) | Prefer for high-reliability industrial systems requiring extended surge endurance |
Compared with BZX84-C22,215, the MMBZ5247BS-7-F offers higher power headroom but requires verification of thermal layout compatibility, while the BZX84-C22-TP delivers superior surge immunity and lower leakage - both retain identical 22 V regulation and SOT23 mounting, enabling drop-in substitution where power or reliability margins are constrained.

FAQ
What is the Zener voltage tolerance and test condition for BZX84-C22,215?
The BZX84-C22,215 has a nominal Zener voltage of 22 V with ±5 % tolerance, specified at IZ = 5 mA and Tj = 25 °C. The actual working range is 20.8 V to 23.3 V under these conditions, as confirmed in Table 8 of the Rev. 7 datasheet.
Can BZX84-C22,215 be used in automotive applications?
No - BZX84-C22,215 is not automotive-qualified. Per Section 13 of the datasheet, this part is classified as non-automotive; Nexperia explicitly states that only designated -Q variants meet AEC-Q101 requirements. Use only in industrial, consumer, or communications equipment.
What is the thermal resistance from junction to ambient, and how is it measured?
Rth(j-a) is 500 K/W, measured with the device mounted on an FR4 PCB with single-sided 70 µm copper, tin-plated, and using the standard SOT23 footprint per Figure 12. This value applies in free-air convection and assumes no additional heatsinking or board copper area beyond the recommended layout.
How does the temperature coefficient affect regulation stability over temperature?
At IZ = 5 mA, the temperature coefficient is +15.4 mV/K, meaning the Zener voltage increases by ~15.4 mV per degree Celsius rise. This positive drift must be accounted for in wide-temperature-range designs; for example, over −40 °C to +85 °C ambient, VZ shifts by approximately ±1.9 V from nominal 22 V.
