Product details
Overview
BZX84C3V0TS-7-F from Diodes Incorporated is a triple-element, ultra-small surface-mount Zener diode array in SOT-363 package, with nominal Zener voltage 3.0 V (min 2.8 V, max 3.2 V), 5 mA test current, 95 Ω max Zener impedance at 5 mA, and 200 mW power dissipation - used for precision voltage reference and overvoltage protection in compact DC power rails.
For engineers reviewing the BZX84C3V0TS-7-F datasheet, BZX84C3V0TS-7-F pinout, BZX84C3V0TS-7-F application, or BZX84C3V0TS-7-F equivalent, key selection criteria include Zener voltage tolerance (±0.2 V), low dynamic impedance (95 Ω), triple-isolated structure for multi-rail clamping, and RoHS-compliant matte tin plating on Alloy 42 leadframe.
Technical Context
This device integrates three electrically isolated Zener diodes in a single SOT-363 package, enabling independent voltage regulation or clamping on three separate signal or supply lines without cross-coupling. Each element operates with identical electrical specs: 3.0 V nominal Zener voltage, 5 mA test current, and 95 Ω maximum dynamic impedance at 1 kHz.
Thermal performance is defined by 625 °C/W junction-to-ambient thermal resistance when mounted on FR4 with recommended pad layout, and full operation across –65 °C to +150 °C ambient temperature range. Reverse leakage is limited to 10 µA at 1.0 V, supporting low-power standby integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.0 V nominal, 2.8–3.2 V range at IZT = 5 mA - ensures stable reference within ±6.7% tolerance for 3.3 V rail monitoring |
| Zener Impedance (ZZT) | ≤95 Ω at IZT = 5 mA - maintains tight regulation under load transients in feedback loops |
| Power Dissipation (PD) | 200 mW - supports continuous clamping in low-current protection circuits without heatsinking |
| Reverse Leakage (IR) | ≤10 µA at VR = 1.0 V - minimizes quiescent current in battery-backed systems |
| Thermal Resistance (RθJA) | 625 °C/W - defines derating slope of 1.6 mW/°C above 25 °C ambient on standard FR4 layout |
| Operating Temperature | –65 °C to +150 °C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
SOT-363 (SC-70-6) ultra-small plastic package with six terminals: three anodes and three cathodes arranged as three isolated diode elements. Molded 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 | Connects to protected node requiring 3.0 V clamping; reverse-biased during normal operation |
| C1 | Cathode of Diode 1 | Reference node tied to regulated 3.0 V rail or ground return path |
| A2 | Anode of Diode 2 | Independent clamping input for second circuit node - no internal connection to Diode 1 or 3 |
| C2 | Cathode of Diode 2 | Isolated return path; enables dual-rail protection without shared impedance |
| A3 | Anode of Diode 3 | Third independent clamping input; supports triple-voltage monitoring in space-constrained designs |
| C3 | Cathode of Diode 3 | Third dedicated cathode terminal - allows discrete biasing or series-Zener configurations |
Key Features
| Feature | Design Value |
|---|---|
| Triple isolated Zener elements | Enables simultaneous voltage clamping on three independent nets without crosstalk or shared thermal path |
| Low Zener impedance (95 Ω) | Delivers <±0.1 V regulation shift under ±1 mA load variation - critical for ADC reference stability |
| SOT-363 footprint (2.2 × 1.35 mm) | Reduces PCB area by >50% vs. three discrete SOD-323 Zeners - ideal for wearables and sensor modules |
| RoHS-compliant matte tin plating | Ensures solderability and long-term intermetallic reliability without lead-based contamination risks |
Applications
| USB Interface Protection | IoT Sensor Node Reference |
|---|---|
Use Scenario: Clamping D+ and D− lines against ESD and bus overvoltage in USB 2.0 peripheral designs. IC Role / Device Role / Timing Role: Zener diode array provides bidirectional transient suppression while maintaining signal integrity below 480 Mbps. Use Value: Triple isolation prevents coupling between data lines; 3.0 V breakdown matches USB suspend voltage threshold. | Use Scenario: Providing stable 3.0 V reference for 12-bit SAR ADC in battery-powered environmental sensors. IC Role / Device Role / Timing Role: Acts as shunt reference with minimal quiescent current (≤10 µA at 1 V reverse), extending battery life. Use Value: Low 95 Ω impedance ensures <0.1 % reference error under ADC sampling load transients. |
| Automotive Body Control Module | Industrial PLC Input Conditioning |
Use Scenario: Protecting microcontroller GPIOs and LIN bus transceivers from load dump and inductive kickback. IC Role / Device Role / Timing Role: Three independent Zeners clamp VCC, LIN line, and wake-up input simultaneously in compact ECUs. Use Value: –65 °C to +150 °C rating supports under-hood deployment; SOT-363 withstands reflow and vibration. | Use Scenario: Level-shifting and overvoltage protection for 24 V digital inputs in programmable logic controllers. IC Role / Device Role / Timing Role: Used in series with current-limiting resistor to clamp input to 3.0 V before optocoupler or Schmitt trigger. Use Value: Tight 2.8–3.2 V Zener window ensures reliable tripping at 3.3 V logic thresholds without false triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | Single-element SOT-363 Zener (3.0 V); same package but only one diode | Requires three devices for triple-clamp function - increases PCB area and assembly cost | Select when only one clamping node is needed or board layout permits discrete placement |
| BZX84C3V0LT1G | Single-element SOT-23 Zener (3.0 V); lower power (350 mW), higher ZZT (150 Ω) | Larger footprint than SOT-363; not suitable for space-constrained triple-rail layouts | Choose for higher-power single-node clamping where thermal margin is critical |
Compared with MMBZ5226BS-7-F and BZX84C3V0LT1G, BZX84C3V0TS-7-F uniquely delivers three matched, isolated 3.0 V Zeners in one SOT-363 - reducing component count by 67%, minimizing layout complexity, and ensuring voltage matching across rails without binning.

FAQ
What is the maximum reverse current at 1.0 V for BZX84C3V0TS-7-F?
The maximum reverse current (IR) is 10 µA at VR = 1.0 V and TA = 25 °C, as specified in the Electrical Characteristics table. This value remains valid across the full operating temperature range and confirms suitability for low-leakage bias networks and battery-sensitive applications.
Can BZX84C3V0TS-7-F be used in parallel for higher power handling?
No - the three diodes are electrically isolated but share a common thermal mass in the SOT-363 package. Parallel connection of elements is not supported; total power dissipation remains limited to 200 mW. For higher power, use discrete diodes with individual thermal paths.
Is the marking code 'KRD' visible on the top surface of the device?
Yes - the top-marking code 'KRD' (per the Electrical Characteristics table) is laser-trimmed on the package surface, along with a two-character date code (e.g., 'UO' for week 40, 2007). Marking orientation follows the diagram in the datasheet, with A1 pin identified by a notch or dot.
Does this device meet AEC-Q200 stress testing requirements?
No - BZX84C3V0TS-7-F is not AEC-Q200 qualified. While it operates from –65 °C to +150 °C and is used in automotive body control modules, formal qualification requires additional test reports (e.g., temperature cycling, humidity bias). For AEC-Q200-compliant alternatives, consult Diodes Incorporated's Automotive Grade portfolio.
