Product details
Overview
DF2S6.2ASL,L3F from Toshiba Electronic Devices & Storage Corporation is a bidirectional ESD protection diode in SL2 (1-1AL1A) package, rated for ±30 kV IEC61000-4-2 contact discharge, 6.2 V zener voltage, 150 °C junction temperature, and 32 pF capacitance - deployed on high-speed USB, HDMI, and audio signal lines to suppress electrostatic transients.
For engineers reviewing the DF2S6.2ASL,L3F datasheet, DF2S6.2ASL,L3F pinout, DF2S6.2ASL,L3F application, or DF2S6.2ASL,L3F equivalent, key selection criteria include clamping voltage at 1 A (10 V), dynamic impedance (0.3 Ω), low leakage (<2.5 µA at 5 V), and compatibility with space-constrained portable electronics requiring sub-1 mm² footprint.
Technical Context
The DF2S6.2ASL,L3F uses silicon epitaxial planar construction to deliver bidirectional transient voltage suppression with symmetrical clamping behavior. Its internal structure consists of two anti-series Zener diodes enabling equal positive/negative ESD pulse handling without polarity dependency.
Designed per IEC61000-4-2 and IEC61000-4-5 standards, it supports 8/20 µs surge waveforms up to 15 A peak pulse current and achieves 18.5 V clamping at 30 A TLP testing - confirming robustness against system-level ESD events while maintaining low capacitance for signal integrity preservation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC61000-4-2) | ±30 kV contact - exceeds Level 4 immunity for consumer and industrial interfaces |
| Zener Voltage (VZ) | 6.2 V at 5 mA - sets precise clamping threshold for 5 V logic rails |
| Clamp Voltage (VC) | 10 V at IPP = 1 A - limits downstream IC stress during fast ESD transients |
| Total Capacitance (Ct) | 32 pF at 0 V, 1 MHz - enables use on USB 2.0 and audio lines without signal degradation |
| Dynamic Impedance (ZZ) | 0.3 Ω - ensures rapid voltage collapse during ESD events for effective protection |
| Working Peak Reverse Voltage (VRWM) | 5 V - matches standard 3.3–5 V interface supply domains with margin |
| Peak Pulse Power (PPK) | 2.5 W at 8/20 µs - sustains short-duration surges without thermal runaway |
Pinout & Package
DF2S6.2ASL,L3F is housed in the SL2 (TOSHIBA 1-1AL1A) surface-mount package - a 0.6 × 0.3 × 0.24 mm ultra-miniature leadless chip-scale package weighing 0.2 mg, optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Reference terminal for one Zener junction; connects to protected line in bidirectional configuration |
| 2 | Anode | Reference terminal for second Zener junction; completes symmetrical clamp path across signal line |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Symmetrical ±30 kV IEC61000-4-2 performance eliminates need for polarity-aware layout |

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 NZQ2S6.2W | Same SL2 package, 6.2 V VZ, but higher clamping voltage (12.5 V at 1 A) and 45 pF capacitance | Less suitable for high-speed USB; better for lower-frequency industrial I/O where capacitance is less critical | Select when higher surge margin is prioritized over signal integrity |
| Vishay ESDBLE6.2 | 0402 package (1.0 × 0.5 mm), 6.2 V VZ, 11 V clamping at 1 A, 25 pF capacitance | Larger footprint than SL2; lower capacitance benefits RF-sensitive designs but requires more board area | Prefer when 25 pF is mandatory and PCB space allows 0402 placement |
Compared with NZQ2S6.2W and ESDBLE6.2, DF2S6.2ASL,L3F delivers the lowest combination of capacitance (32 pF) and clamping voltage (10 V at 1 A) in the smallest footprint (0.6 × 0.3 mm), making it optimal for miniaturized high-speed digital interfaces where both signal fidelity and board area are constrained.

FAQ
What is the maximum working voltage supported by DF2S6.2ASL,L3F?
The DF2S6.2ASL,L3F has a working peak reverse voltage (VRWM) of 5 V, meaning it is rated for continuous operation on signal lines with up to 5 V DC bias - such as USB 2.0, HDMI DDC, and 5 V logic I/O. Exceeding this voltage risks premature conduction and reduced ESD protection margin. The DF2S6.2ASL,L3F must not be used in circuits where steady-state reverse voltage exceeds 5 V.
Does DF2S6.2ASL,L3F support bidirectional ESD protection?
Yes, DF2S6.2ASL,L3F is explicitly designed as a bidirectional ESD protection device, confirmed by its ±30 kV IEC61000-4-2 contact rating and symmetrical internal anti-series Zener structure. This allows single-device protection of AC-coupled or differential signal lines like USB D+/D− without polarity concerns - unlike unidirectional diodes that require careful orientation.
What is the clamping voltage of DF2S6.2ASL,L3F at 2.5 A peak pulse current?
The DF2S6.2ASL,L3F clamps to 14 V at 2.5 A peak pulse current (IPP), as specified in its Electrical Characteristics table. This value reflects real-world transient suppression performance under moderate surge conditions and is critical for ensuring downstream ICs remain within safe absolute maximum ratings during ESD events.
Can DF2S6.2ASL,L3F be used on high-speed interfaces like USB 3.0 or MIPI?
No, DF2S6.2ASL,L3F is not recommended for USB 3.0 or MIPI interfaces due to its 32 pF capacitance, which would degrade signal integrity at multi-Gbps data rates. It is validated for USB 2.0 (480 Mbps) and lower-speed buses like HDMI DDC (≤100 kHz) and audio lines. For USB 3.0, devices with <1.5 pF capacitance - such as specialized TVS arrays - are required.
What is the thermal limit for continuous operation of DF2S6.2ASL,L3F?
The DF2S6.2ASL,L3F has a maximum junction temperature (Tj) rating of 150 °C and a storage temperature range of −55 °C to +150 °C. Continuous operation must maintain junction temperature below 150 °C - achievable in typical handheld applications with low ambient temperatures and minimal power dissipation, since the DF2S6.2ASL,L3F conducts only during transient events and draws negligible steady-state current.
