Product details
Overview
BZX84C22TS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array with three isolated 22 V ±5% Zener elements in a single SOT-363 package, rated for 200 mW total power dissipation, 55 Ω typical Zener impedance at 5 mA, and reverse current ≤0.1 µA at 15.4 V, used for precision voltage regulation and overvoltage protection in compact DC power rails.
For engineers reviewing the BZX84C22TS-7-F datasheet, BZX84C22TS-7-F pinout, BZX84C22TS-7-F application, or BZX84C22TS-7-F equivalent, this device supports multi-rail clamping, low-power reference generation, and ESD-tolerant signal line conditioning where space-constrained triple-Zener functionality is required.
Technical Context
This triple Zener array integrates three electrically isolated diodes sharing only mechanical packaging-no internal connection-enabling independent biasing of each element. Each diode exhibits a nominal Zener voltage of 22.0 V (20.8–23.3 V range), with 5 mA test current and temperature coefficient of +16.4 to +20.0 mV/°C.
Thermal performance is defined by 625 °C/W junction-to-ambient thermal resistance on FR4 PCB with recommended pad layout, and full operation across –65 °C to +150 °C ambient. The device uses matte tin-plated Alloy 42 leadframe and green molding compound compliant with RoHS and halogen-free requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22.0 V nominal, 20.8–23.3 V min/max at IZT = 5 mA - defines stable regulation point under standard test conditions |
| Power Dissipation (PD) | 200 mW - maximum continuous power per device, derates linearly above 25 °C ambient per Fig. 1 |
| Zener Impedance (ZZT) | 55 Ω typical at 1 kHz, 5 mA - determines output voltage stability under dynamic load changes |
| Reverse Current (IR) | ≤0.1 µA at VR = 15.4 V - ensures minimal leakage in standby or high-impedance sensing nodes |
| Thermal Resistance (RθJA) | 625 °C/W - quantifies self-heating impact on Zener voltage drift during sustained conduction |
| Operating Temperature | –65 °C to +150 °C - supports automotive under-hood, industrial control, and extended-environment deployments |
Pinout & Package
SOT-363 (SC-70-6) ultra-small surface-mount package with six terminals: three anodes and three cathodes arranged as three independent diodes. Molded plastic case meets UL 94V-0 flammability rating; moisture sensitivity level 1 per J-STD-020D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Current entry point for first Zener element; connects to regulated rail or clamp node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5222BS-7-F | Single 22 V Zener in SOT-323; no triple-element integration | Requires three discrete placements and routing; higher assembly cost and larger footprint | Select when only one regulated rail is needed or when thermal separation between Zeners is critical |
| BZX84C22LT1G | Single-element SOT-23 variant; same 22 V rating but no multi-diode integration | Lacks channel isolation; unsuitable for multi-node clamping without external decoupling | Choose for cost-sensitive single-rail designs where board space is less constrained than component count |
Compared with MMBZ5222BS-7-F and BZX84C22LT1G, BZX84C22TS-7-F delivers three independent 22 V Zener functions in one SOT-363 footprint-reducing component count by 67%, minimizing interconnect inductance, and ensuring matched voltage drift across channels for tightly coupled protection schemes.

FAQ
What is the maximum reverse voltage that can be safely applied before breakdown?
The BZX84C22TS-7-F has a nominal Zener voltage of 22.0 V with a guaranteed range of 20.8 V to 23.3 V at 5 mA test current. Breakdown begins within this band; applying more than 23.3 V continuously risks exceeding the 200 mW power limit unless current is strictly limited below 8.6 mA.
Can all three Zener diodes operate simultaneously at full rated power?
No. The 200 mW rating applies to the entire SOT-363 package. Simultaneous operation of all three diodes at full 5 mA (15 mA total) would exceed thermal limits. Derating is required per the power derating curve (Fig. 1); at 70 °C ambient, max total power drops to ~120 mW.
Is the SOT-363 package compatible with standard reflow profiles for lead-free assembly?
Yes. The device is RoHS-compliant with matte tin plating and rated for moisture sensitivity level 1 (MSL-1), allowing unlimited floor life and compatibility with J-STD-020-compliant lead-free reflow profiles up to 260 °C peak temperature.
How does the temperature coefficient affect regulation accuracy over temperature?
The specified TC is +16.4 to +20.0 mV/°C at 5 mA. Over a 100 °C range (–25 °C to +75 °C), this introduces up to ±1.7 V drift from nominal 22 V - a ±7.7% shift. For high-accuracy references, active compensation or tighter TC devices (e.g., BZX84C22E) should be considered.
