Product details
Overview
DT2042-01CSP from Diodes Incorporated is a unidirectional TVS diode designed for ESD protection of high-speed data lines in portable electronics. It delivers 6V breakdown voltage, 6.5A peak pulse current (8/20μs), 0.8pF input capacitance, and ±20kV IEC 61000-4-2 air/contact ESD immunity - enabling robust signal integrity in space-constrained USB, audio, or camera interfaces.
For engineers reviewing the DT2042-01CSP datasheet, DT2042-01CSP pinout, DT2042-01CSP application, or DT2042-01CSP equivalent, key selection criteria include low-channel capacitance for high-frequency signal paths, precise clamping behavior at 7.0V (IPP = 1A), compliance with IEC 61000-4-2/4-4, thermal derating up to +150°C, and X3-DSN1006-2 (Type B) chip-scale package compatibility with fine-pitch PCB layouts.
Technical Context
This TVS operates as a single-channel unidirectional clamp between I/O and ground, triggered by transient overvoltage exceeding its 6V minimum breakdown threshold. Its dynamic resistance of 0.2Ω ensures rapid voltage limiting during ESD events, while the 0.8pF capacitance minimizes signal distortion on 100MHz+ interfaces.
The device uses NiAu bump terminals on a chip-scale package with electrically active side walls, requiring strict solder process control to avoid shorts. Its 500°C/W junction-to-ambient thermal resistance assumes FR-4 PCB mounting per Diodes' recommended pad layout (2oz copper).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6 V min - Ensures reliable triggering before damage to downstream 5V logic or USB PHY circuits |
| Clamping Voltage (VCL) | 7.0 V @ 1A - Limits transient voltage seen by protected IC to safe level during ESD strike |
| Input Capacitance (CIN) | 0.8 pF @ 0V - Preserves signal integrity on high-speed lines (e.g., USB 2.0, MIPI D-PHY) |
| ESD Rating | ±20 kV air/contact - Meets IEC 61000-4-2 Level 4, highest industrial immunity class |
| Peak Pulse Current (IPP) | 6.5 A @ 8/20μs - Handles severe surge transients without degradation |
| Reverse Standoff (VRWM) | 5 V max - Matches common I/O supply rails, preventing leakage during normal operation |
| Thermal Resistance (RθJA) | 500 °C/W - Requires careful PCB copper area planning for sustained power dissipation |
Pinout & Package
Package: X3-DSN1006-2 (Type B) chip-scale package - 1.0mm × 0.6mm footprint, 0.275mm nominal height, NiAu bump terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (I/O side) | Connected to protected signal line; must be routed with controlled impedance and minimal stub length |
| Pin 2 | Cathode (GND side) | Direct low-inductance connection to system ground plane required for effective clamping |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD immunity | ±20 kV air/contact - Eliminates need for secondary ESD protection in certified consumer designs |
| Low input capacitance | 0.8 pF - Enables use on 480 Mbps USB 2.0 or 1.5 Gbps MIPI D-PHY without eye diagram degradation |
| Unidirectional configuration | Single anode-cathode path - Optimized for DC-biased interfaces like USB D+/D− or audio codecs |
| Chip-scale packaging | X3-DSN1006-2 - Reduces board area by >50% vs. SOD-323, critical for ultra-thin mobile PCBs |

FAQ
What is the maximum operating temperature for DT2042-01CSP?
The DT2042-01CSP supports continuous operation from –65°C to +150°C. Its thermal resistance (RθJA = 500°C/W) assumes mounting on a standard FR-4 PCB with Diodes' recommended 2oz copper pad layout; derating is required above +70°C ambient per Figure 2 in DS39248.
Is DT2042-01CSP pin-compatible with other Diodes TVS diodes in the X3-DSN1006-2 package?
No - DT2042-01CSP is a unidirectional device with Anode on Pin 1 and Cathode on Pin 2. Bidirectional variants (e.g., DT2042-02CSP) reverse polarity; substituting without circuit review risks incorrect clamping direction and protection failure.
Does DT2042-01CSP meet automotive AEC-Q200 requirements?
No - DT2042-01CSP is not qualified to AEC-Q200. It is specified for commercial/industrial portable applications only. Diodes offers AEC-Q200-qualified alternatives such as the D24Z5.1LPSQ series for automotive infotainment interfaces.
How does the 0.8pF input capacitance impact 100MHz+ signal integrity?
At 100MHz, 0.8pF introduces only ~2kΩ capacitive reactance, minimizing insertion loss and phase shift. Measured data (Figure 3 in DS39248) confirms stable capacitance down to 0V bias, ensuring consistent performance across logic-high/low transitions on high-speed buses.
