Product details
Overview
DF3A5.6LFV(TPL3,Z) from Toshiba is a dual-channel ESD protection diode array designed for high-speed data lines, featuring 5.6 V Zener voltage (typ.), 8.0 pF terminal capacitance (typ.), and ±8 kV IEC61000-4-2 contact discharge immunity - deployed in USB 2.0, HDMI, and audio jack interfaces.
For engineers reviewing the DF3A5.6LFV(TPL3,Z) datasheet, DF3A5.6LFV(TPL3,Z) pinout, DF3A5.6LFV(TPL3,Z) application, or DF3A5.6LFV(TPL3,Z) equivalent, key selection criteria include low-capacitance bidirectional clamping, dual-cathode/anode topology, guaranteed ESD robustness without DC voltage regulation intent, and JEITA-registered VESM package compatibility.
Technical Context
This device implements two independent Zener-based ESD clamps in a single ultra-compact VESM package (1.2 × 0.8 × 0.4 mm), with cathodes isolated and shared anode configuration. It operates strictly as a transient suppressor - not a voltage regulator - with no DC biasing requirement beyond signal line placement.
Electrical behavior is defined by dynamic impedance ≤3 Ω at 5 mA, reverse leakage ≤1.0 μA at 3.5 V, and capacitance stable across 0–5 V reverse bias. The ±8 kV IEC61000-4-2 rating applies only to ESD pulse suppression; continuous operation above 3.5 V reverse voltage risks degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage | 5.6 V (typ.) - clamping threshold for ESD transients on signal lines |
| Terminal capacitance | 8.0 pF (typ.) - minimal loading on high-speed interfaces like USB 2.0 (480 Mbps) |
| ESD immunity | ±8 kV (IEC61000-4-2 contact discharge) - meets industrial-grade ESD protection requirements |
| Dynamic impedance | ≤3 Ω - ensures fast, low-voltage overshoot clamping during ESD events |
| Reverse leakage | ≤1.0 μA at 3.5 V - negligible DC loading on active signal paths |
| Power dissipation | 150 mW (on FR4, 25.4 mm²) - defines safe single-pulse energy handling under ESD stress |
Pinout & Package
VESM package (Toshiba designation 1-1Q1B), dimensions 1.2 × 0.8 × 0.4 mm, weight 1.5 mg (typ.), JEITA-compliant ultra-miniature surface-mount outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD clamp anode connection point for first protected signal line |
| 2 | Cathode 2 | ESD clamp anode connection point for second protected signal line |
| 3 | Anode | Common cathode return path - tied to system ground or low-impedance reference plane |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel ESD protection | Two independent clamps in one VESM footprint - reduces PCB area vs. discrete diodes |
| Low signal-line capacitance | 8.0 pF typ. - preserves signal integrity up to 480 Mbps without equalization |
| Guaranteed ±8 kV ESD rating | Validated per IEC61000-4-2 contact discharge - eliminates need for external test validation |
| No DC regulation function | Explicitly specified for ESD-only use - prevents misuse as Zener voltage reference |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Lines |
|---|---|
Use Scenario: Protecting differential USB 2.0 D+/D− traces from user-port ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed adjacent to connector, clamping spikes before they reach PHY IC. Use Value: 8.0 pF capacitance avoids signal rise-time degradation; ±8 kV rating exceeds USB-IF compliance requirement (±8 kV contact). | Use Scenario: Safeguarding HDMI DDC (I²C) and CEC control lines against electrostatic discharge from cable mating/unmating. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp on 3.3 V logic lines, preserving I²C timing margins and pull-up functionality. Use Value: ≤1.0 μA leakage at 3.5 V prevents unintended bus pull-down; dual-channel matches DDC SDA/SCL pair layout. |
| Smartphone Audio Jacks | Industrial Sensor Interface Lines |
Use Scenario: ESD protection for TRRS microphone and headset detection lines exposed to frequent human contact. IC Role / Device Role / Timing Role: Ground-referenced Zener clamp on analog audio paths, activated only during >5.6 V transients. Use Value: Ultra-small VESM package fits tight space behind 3.5 mm jack; no DC conduction avoids audio DC offset. | Use Scenario: Shielding 0–5 V analog sensor outputs (e.g., pressure, temperature) from field-induced ESD in factory environments. IC Role / Device Role / Timing Role: Signal-line protector between sensor front-end and ADC input, with common-anode grounding to chassis. Use Value: 150 mW pulse power rating handles multi-kV ESD without thermal runaway; −55 to 150 °C storage range supports extended industrial deployment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NZQ2701DT5G | Single-channel, 2.5 pF CT, 5.6 V VZ, SOD-923 package (1.0 × 0.6 × 0.4 mm) | Lower capacitance but requires two devices for dual-line protection; smaller footprint but higher assembly cost | Select when minimizing trace capacitance is critical and board space allows separate placement |
| Diodes Inc. D3V3Z5U-7 | Dual-channel, 12 pF CT, 3.3 V VZ, SOT-523 package (1.6 × 0.8 × 0.6 mm) | Higher capacitance limits use to ≤100 Mbps interfaces; lower clamping voltage suits 3.3 V I/O domains | Select for 3.3 V logic systems where tighter clamping voltage outweighs speed penalty |
Compared with NZQ2701DT5G and D3V3Z5U-7, DF3A5.6LFV(TPL3,Z) uniquely balances dual-channel integration, 8 pF capacitance, and 5.6 V clamping in a sub-1 mm² footprint - making it optimal for space-constrained USB/HDMI interface protection where 480 Mbps signal fidelity and ±8 kV robustness are jointly required.

FAQ
Is DF3A5.6LFV(TPL3,Z) rated for continuous DC voltage regulation?
No. DF3A5.6LFV(TPL3,Z) is explicitly designated for ESD protection only and must not be used as a Zener voltage reference or constant-voltage regulator. Its electrical characteristics - including Zener voltage tolerance (5.3–6.0 V) and dynamic impedance - are specified under transient pulse conditions, not steady-state DC operation. Using DF3A5.6LFV(TPL3,Z) for DC regulation violates Toshiba's stated product restrictions and may cause premature failure.
What is the maximum recommended operating temperature for DF3A5.6LFV(TPL3,Z)?
The junction temperature limit for DF3A5.6LFV(TPL3,Z) is 150 °C, and the storage temperature range is −55 to 150 °C. For reliable long-term operation, Toshiba recommends derating power dissipation above 25 °C ambient and maintaining PCB thermal relief consistent with the 150 mW rating on FR4. DF3A5.6LFV(TPL3,Z) is not qualified for automotive AEC-Q101 stress testing.
Can DF3A5.6LFV(TPL3,Z) be used on 5 V logic lines?
Yes - DF3A5.6LFV(TPL3,Z) is compatible with 5 V logic interfaces because its 5.6 V (typ.) Zener voltage provides margin above the 5 V rail while remaining below typical absolute maximum I/O ratings (e.g., 6.5 V). Its ≤1.0 μA reverse leakage at 3.5 V ensures minimal loading. DF3A5.6LFV(TPL3,Z) has been validated in USB 2.0 and industrial sensor applications with 5 V signaling.
Does DF3A5.6LFV(TPL3,Z) meet RoHS and REACH requirements?
Yes. DF3A5.6LFV(TPL3,Z) complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed by Toshiba's material declarations. Lead-free soldering is supported per J-STD-020 moisture sensitivity level 1 (MSL-1), and the VESM package uses matte tin termination. Full compliance documentation is available upon request for DF3A5.6LFV(TPL3,Z).
How is the anode terminal of DF3A5.6LFV(TPL3,Z) intended to be connected in circuit?
The anode (Pin 3) of DF3A5.6LFV(TPL3,Z) must be connected to a low-impedance ground plane - not left floating or tied to VCC. This configuration enables bidirectional clamping: positive transients divert from cathodes to ground, and negative transients draw current from ground into cathodes. Incorrect anode routing (e.g., to VCC) disables ESD protection and may damage DF3A5.6LFV(TPL3,Z) during discharge events.
