Product details
Overview
TBZ363C6V4-7-F from Diodes Incorporated is a triple bi-directional surface-mount Zener diode array with nominal Zener voltages of 6.4 V (±5%), 50 Ω max Zener impedance at 5 mA, and 200 mW power dissipation in SOT-363 package; used for ESD and transient voltage suppression in low-voltage I/O lines of portable electronics.
For engineers reviewing the TBZ363C6V4-7-F datasheet, TBZ363C6V4-7-F pinout, TBZ363C6V4-7-F application, or TBZ363C6V4-7-F equivalent, key selection criteria include bidirectional clamping capability, low leakage (<2 µA at 5.12 V), thermal resistance (625 °C/W), and RoHS-compliant green molding compound compatibility with reflow soldering.
Technical Context
This device integrates three independent, symmetrical Zener diodes in a single SOT-363 package, each configured for bidirectional transient voltage suppression across differential or single-ended signal paths. It operates within -65°C to +150°C ambient range and supports pulse-based Zener regulation per JEDEC JESD22-A114.
Clamping behavior is defined by 6.08 V minimum and 6.72 V maximum Zener voltage at 5 mA test current, with temperature coefficient ranging from -4.0 to +0.5 mV/°C - enabling stable protection in battery-powered systems where supply rails drift near threshold limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.4 V nominal, 6.08–6.72 V range at 5 mA - ensures reliable clamping above logic-high thresholds in 5 V and 3.3 V interfaces |
| Max Zener Impedance | 50 Ω at 5 mA - maintains tight voltage regulation during fast transients up to 100 ns duration |
| Power Dissipation | 200 mW - supports continuous operation on FR4 PCBs with recommended pad layout per AP02001 |
| Reverse Leakage | ≤2.0 µA at 5.12 V - minimizes standby current in always-on sensor or communication I/O circuits |
| Thermal Resistance | 625 °C/W junction-to-ambient - requires minimal copper area for thermal management in space-constrained layouts |
| Operating Temp | -65°C to +150°C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
SOT-363 (SC-70-6) plastic surface-mount package with six terminals in a dual-row configuration; molded using halogen-free, UL 94V-0 green compound; moisture sensitivity level 1 per J-STD-020D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Connects to protected line A; forms cathode-anode pair with Pin 2 for bidirectional clamping |
| 2 | Cathode of Diode 1 | Shared node with Pin 1 for symmetric breakdown in either polarity |
| 3 | Anode of Diode 2 | Connects to protected line B; pairs with Pin 4 for second independent clamp path |
| 4 | Cathode of Diode 2 | Shared node with Pin 3; enables differential or common-mode suppression between Lines A and B |
| 5 | Anode of Diode 3 | Connects to ground reference or VCC; forms third clamp leg with Pin 6 |
| 6 | Cathode of Diode 3 | Common reference terminal; ties all three Zeners to system GND or rail for coordinated clamping |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Zener Clamping | Three independent symmetrical diodes enable ±6.4 V clamping without external polarity biasing |
| Ultra-Small Footprint | SOT-363 occupies <1.3 mm × 2.2 mm area - saves board space vs. discrete dual-diode solutions |
| Lead-Free & Green Molding | Matte tin-plated Alloy 42 leadframe and halogen-free epoxy meet RoHS and JEDEC MSL-1 requirements |
| Low-Temp Coefficient | -4.0 to +0.5 mV/°C TC ensures <±3% VZ shift over -40°C to +85°C operating range |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional Zener array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC3016LSD-7-F | Single-channel 6.8 V Zener, SOT-23-3; no integrated triple array | Requires three devices for same function; higher assembly cost and footprint | Select when only one line needs protection or board layout favors discrete placement |
| PESD5V0S1BA,115 | Unidirectional ESD protection diode; 5.0 V working voltage, 12 A peak pulse current | Not bidirectional; lacks Zener regulation; optimized for IEC 61000-4-2, not general-purpose clamping | Prefer for certified ESD-only applications with strict compliance testing requirements |
Compared with DMC3016LSD-7-F and PESD5V0S1BA,115, TBZ363C6V4-7-F uniquely delivers integrated triple bidirectional clamping in one SOT-363 footprint, enabling compact, thermally efficient protection for multi-signal interfaces without compromising regulation accuracy or temperature stability.

FAQ
What is the maximum peak pulse power this device can handle?
TBZ363C6V4-7-F is rated for 200 mW steady-state power dissipation. Its peak pulse power handling depends on waveform duration and duty cycle; per the datasheet's derating curve, it supports up to ~1.2 W for 10 ms pulses at 25°C ambient, assuming proper PCB copper area per AP02001 layout guidelines.
Can this part replace a single Zener diode in a unidirectional circuit?
No - TBZ363C6V4-7-F contains three bidirectional Zener structures. Each diode conducts in both directions, making it unsuitable as a replacement for unidirectional Zener regulation. For unidirectional use, consider discrete Zeners like BZX584C6V2 or equivalent.
Is the SOT-363 package compatible with standard reflow profiles?
Yes - the device is qualified for lead-free reflow per JEDEC J-STD-020D Level 1, with peak temperatures up to 260°C. Its green molding compound and matte tin finish ensure robust wetting and intermetallic formation under standard Pb-free thermal profiles.
How does the temperature coefficient affect clamping performance in automotive applications?
With a TC of -4.0 to +0.5 mV/°C, TBZ363C6V4-7-F exhibits minimal Zener voltage drift - less than ±0.3 V over -40°C to +125°C. This ensures consistent clamping margins across automotive temperature ranges without requiring compensation circuitry.
