Product details
Overview
TBZ363C7V0-7-F from Diodes Incorporated is a triple bi-directional surface-mount Zener diode array with nominal Zener voltage 7.0 V (±5%), 200 mW power dissipation, 18 Ω max Zener impedance at 5 mA, and operating temperature range −65 °C to +150 °C; used for ESD protection and transient voltage suppression in low-power I/O interfaces.
For engineers reviewing the TBZ363C7V0-7-F datasheet, TBZ363C7V0-7-F pinout, TBZ363C7V0-7-F application, or TBZ363C7V0-7-F equivalent, key selection criteria include bidirectional clamping capability, SOT-363 footprint compatibility, thermal resistance of 625 °C/W, and guaranteed 7.0 V regulation under 5 mA test current.
Technical Context
This device integrates three independent, symmetrically configured Zener diodes in a single SOT-363 package, enabling simultaneous bidirectional clamping on three signal lines. Each diode exhibits matched forward and reverse breakdown characteristics, with specified Zener voltage tolerance (±5%) and tight impedance control (18 Ω max at IZT = 5 mA).
Designed for low-energy transient suppression, it operates within a wide ambient temperature range (−65 °C to +150 °C) and delivers stable clamping performance up to its 200 mW power limit when mounted per recommended FR4 pad layout; thermal resistance to ambient is fixed at 625 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (Nominal) | 7.0 V - precise clamping threshold for 3.3 V/5 V logic I/O protection |
| Zener Voltage Range | 6.65 V to 7.35 V - ±5% tolerance ensures predictable turn-on across production lots |
| Max Zener Impedance | 18 Ω at 5 mA - low dynamic resistance maintains tight voltage regulation during fast transients |
| Power Dissipation | 200 mW - defines maximum sustained clamping energy before thermal derating begins |
| Thermal Resistance | 625 °C/W - determines junction temperature rise under steady-state power loading on FR4 PCB |
| Operating Temperature | −65 °C to +150 °C - supports automotive under-hood and industrial control environments |
| Reverse Leakage | 2.0 μA at 5.6 V - minimal standby current preserves signal integrity in high-impedance nodes |
Pinout & Package
Package: SOT-363 - ultra-small 6-pin surface-mount plastic package (2.2 mm × 1.35 mm × 0.9 mm), RoHS-compliant, matte tin-plated leads, moisture sensitivity level 1.

IC Role / Device Role / Timing Role: Three-channel clamp protecting VSENSE, GND, and enable lines simultaneously. Use Value: Matches 7.0 V Zener voltage to common 5 V rail headroom-preventing latch-up in downstream op-amps. | Use Scenario: Guarding touch-screen controller I/Os and battery monitor ADC inputs against human-body-model ESD in handheld diagnostics units. IC Role / Device Role / Timing Role: Ultra-low-leakage (2.0 μA @ 5.6 V) protector preserving microamp-level sensor bias currents. Use Value: SOT-363 footprint allows placement within 2 mm of connectors-minimizing inductance and improving clamping speed. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Zener diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3020LSD-13 | Single N-channel MOSFET with integrated Zener gate protection; not a multi-diode array | Used for discrete FET-level ESD protection-not signal-line clamping | Select only when replacing discrete gate-protected switches, not for multi-line I/O clamping |
| PESD5V0S1BA,115 | Single-line bidirectional TVS with 5.0 V clamping, 0.5 pF capacitance, SOD-323 package | Lacks triple-channel integration; requires three devices for equivalent coverage | Prefer when ultra-low capacitance (<0.5 pF) is mandatory for >100 MHz signals, accepting higher assembly cost |
Compared with DMN3020LSD-13 and PESD5V0S1BA,115, TBZ363C7V0-7-F uniquely delivers three matched 7.0 V bidirectional clamps in one SOT-363 footprint-reducing component count, board space, and interconnect inductance for multi-signal protection without compromising thermal or voltage tolerance specs.

FAQ
What is the maximum peak pulse power this device can handle?
TBZ363C7V0-7-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 200 mW at 25 °C ambient, decreasing linearly to zero at 150 °C. For short pulses (<100 ms), actual energy absorption is limited by thermal mass and PCB layout-not specified as a standalone pulse rating.
Is this part suitable for protecting high-speed data lines like HDMI or PCIe?
No. TBZ363C7V0-7-F has no published capacitance specification and is not characterized for frequencies above 1 MHz. Its design targets low-to-medium speed interfaces (e.g., UART, I²C, CAN, USB 2.0). For HDMI or PCIe, use low-capacitance TVS arrays with documented <0.3 pF channel capacitance and specified bandwidth.
How does the bidirectional behavior manifest electrically?
Each of the three diode elements conducts in both directions: forward-biased like a standard diode below 7.0 V, and reverse-biased into Zener breakdown above 7.0 V. This provides symmetrical clamping-e.g., limiting a +9 V spike to +7.35 V and a −9 V spike to −7.35 V-without requiring external polarity alignment.
Can this device replace a single Zener diode in a voltage reference circuit?
No. TBZ363C7V0-7-F is optimized for transient suppression, not precision voltage reference. Its Zener voltage tolerance is ±5%, and it lacks low-noise design, tight tempco (−1.6 to +1.7 mV/°C), or stability under constant DC bias. Use dedicated reference ICs (e.g., TL431, REF50xx) for regulation or feedback applications.
