Product details
Overview
D1213A-04MR from Diodes Incorporated is a 4-channel low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It features 0.85 pF typical channel capacitance, ±8 kV contact / ±15 kV air IEC 61000-4-2 ESD rating, and operates over 3.3 V to 5.5 V supply range - deployed in USB 2.0, HDMI, and Serial ATA interfaces.
For engineers reviewing the D1213A-04MR datasheet, D1213A-04MR pinout, D1213A-04MR application, or D1213A-04MR equivalent, key selection criteria include channel input capacitance, clamping voltage under 1 A transient, reverse breakdown threshold, thermal resistance (250 °C/W), and MSOP-10 package compatibility with high-density PCB layouts.
Technical Context
This device implements a dual-rail TVS architecture with separate VP (positive rail) and VN (ground rail), enabling bidirectional transient suppression per channel. Each channel integrates stacked top-and-bottom diodes between signal line and VP/VN, delivering symmetrical clamping: +10.0 V (VCL1) for positive transients and –1.7 V (VCL2) for negative transients at 1 A.
It is rated for 6.0 V operating supply (VP–VN), exhibits 6.0 V minimum reverse breakdown (VBR at 1 mA), and maintains leakage below 1.0 μA at 5 V bias. Its 0.85 pF typical input capacitance ensures minimal signal integrity degradation on 480 Mbps USB 2.0 links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | Air ±15 kV / Contact ±8 kV - meets automotive and industrial system-level ESD immunity requirements |
| Channel Input Capacitance | 0.85 pF typical - preserves signal rise/fall times and eye diagram integrity on USB 2.0/HDMI channels |
| Clamping Voltage (IPP = 1 A) | +10.0 V (VCL1), –1.7 V (VCL2) - limits transient overvoltage to safe levels for 3.3 V/5 V interface ICs |
| Reverse Breakdown Voltage | 6.0 V min at 1 mA - ensures reliable turn-on before damage to protected downstream logic |
| Thermal Resistance (RθJA) | 250 °C/W - defines power derating above 25 °C ambient; 500 mW max PD at TA ≤ 25 °C |
| Supply Voltage Range | 3.3 V to 5.5 V - supports both 3.3 V and 5 V I/O domains without level-shifting |
Pinout & Package
Package: MSOP-10, surface-mount, lead-free, halogen-free, RoHS-compliant molded plastic case (UL 94V-0). Moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 6, 9 | Signal Input (Ch1–Ch4) | ESD-protected data lines - each connects to one high-speed interface lane (e.g., USB D+, D–) |
| 2, 5, 7, 10 | No Connection | Unbonded terminals - must remain floating; no internal connection or parasitic coupling |
| 3 | VP (Positive Rail) | Supply rail connection for top-diode anodes - ties to system VCC or I/O domain voltage |
| 8 | VN (Ground Rail) | Reference rail for bottom-diode cathodes - must connect to clean, low-impedance system ground |
Key Features
| Feature | Design Value |
|---|---|
| Low Channel Capacitance | 0.85 pF typical - enables use on 480 Mbps USB 2.0 and 1.5 Gbps DVI/HDMI without measurable jitter increase |
| Asymmetric Clamping | +10.0 V / –1.7 V at 1 A - protects both positive overvoltage and negative undershoot events on single-supply systems |
| AEC-Q101 Qualified | Qualified for automotive applications - validated for temperature cycling, HTRB, and ESD robustness per stress test plan |
| Green Construction | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) - satisfies EU ELV and OEM chemical compliance mandates |
Applications
| USB 2.0 Interface Protection | HDMI Source Port Protection |
|---|---|
Use Scenario: Protecting upstream USB 2.0 host controller ports against ESD events during cable insertion/removal. IC Role / Device Role / Timing Role: Bidirectional TVS array placed directly at connector, shunting transients before reaching PHY or controller. Use Value: 0.85 pF capacitance avoids signal distortion; ±8 kV contact rating exceeds IEC 61000-4-2 system-level test requirement. | Use Scenario: Safeguarding HDMI transmitter outputs (TMDS channels) in set-top boxes or AV receivers. IC Role / Device Role / Timing Role: Per-channel transient suppressor between source driver and HDMI connector, referenced to local 3.3 V and ground rails. Use Value: Symmetrical clamping (+10.0 V / –1.7 V) prevents latch-up in 3.3 V TMDS drivers during hot-plug transients. |
| Serial ATA Data Lane Protection | IEEE 1394 (FireWire) Port Protection |
Use Scenario: Shielding SATA Gen II (3 Gbps) differential pairs in notebook storage controllers from ESD-induced bit errors. IC Role / Device Role / Timing Role: Dual-channel protection per differential pair (one device per TX/RX lane), with shared VP/VN rails. Use Value: Low dynamic resistance (0.9 Ω) ensures fast response and tight clamping margin below SATA receiver absolute maximum ratings. | Use Scenario: Hardening IEEE 1394a/b ports in digital camcorders and editing workstations against repeated connector handling ESD. IC Role / Device Role / Timing Role: Four-channel protector covering all 1394 data/control lines (TPA, TPB, CTL, PRE) in single MSOP-10 footprint. Use Value: AEC-Q101 qualification provides confidence in long-term reliability for portable consumer electronics subjected to mechanical wear. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG (Littelfuse) | 0.6 pF typical capacitance; lower VBR (5.5 V); higher IPP (10 A) | Better suited for ultra-high-speed (>1 Gbps) links but less margin for 5 V tolerant receivers | Select when lowest possible capacitance is critical and system VCC is strictly ≤3.6 V |
| SZ1.8SMCG-4 (ON Semiconductor) | 1.2 pF typical capacitance; higher clamping (+12.5 V); same ±8/±15 kV ESD rating | Higher clamping increases risk of overstress on 3.3 V receivers; better for 5 V-only systems | Prefer where cost sensitivity outweighs signal integrity impact and 5 V operation dominates |
Compared with SP1006-04UTG and SZ1.8SMCG-4, D1213A-04MR delivers optimal balance: 0.85 pF capacitance preserves USB 2.0 timing margins, 6.0 V VBR provides headroom for 5 V receivers, and its AEC-Q101 qualification supports automotive infotainment designs.

FAQ
What is the maximum recommended trace length between D1213A-04MR and the protected connector?
For optimal ESD performance, keep PCB traces from the protected signal pins (1,4,6,9) to the connector ≤3 mm. Longer traces add inductance that degrades clamping response; the device's 0.9 Ω dynamic resistance requires low-inductance layout to achieve specified VCL1/VCL2 under 1 A transients.
Can D1213A-04MR be used to protect 1.8 V I/O interfaces?
No - its 6.0 V minimum reverse breakdown voltage and 3.3 V minimum operating supply make it unsuitable for direct protection of 1.8 V logic. Using it on 1.8 V lines risks premature conduction and increased leakage; a dedicated 1.8 V-rated TVS like D3V3Z5P4U is required.
Does the "MR" suffix indicate tape-and-reel packaging?
Yes - the "-13" suffix in D1213A-04MR-13 explicitly denotes 2500-unit tape-and-reel packaging per JEDEC standard. The base part number D1213A-04MR identifies the device variant; packaging is encoded separately in the full orderable number.
How does the MSOP-10 footprint affect thermal performance in continuous operation?
The MSOP-10 package has RθJA = 250 °C/W on standard FR-4 (2 oz Cu), limiting continuous power dissipation to ~200 mW at 85 °C ambient. It is not intended for sustained DC power handling - its design targets transient ESD suppression only, with peak pulse energy absorbed within microseconds.
