Product details
Overview
D24V0L1B2LPS-7B from Diodes Incorporated is a bidirectional transient voltage suppression (TVS) diode designed for ESD protection of high-speed data lines in portable electronics. It features a 24V reverse standoff voltage, ±20kV IEC 61000-4-2 contact/air discharge rating, 6pF typical input capacitance, and U-DFN1006-2/SWP package - enabling use in USB 2.0, HDMI, and audio interface circuits.
For engineers reviewing the D24V0L1B2LPS-7B datasheet, D24V0L1B2LPS-7B pinout, D24V0L1B2LPS-7B application, or D24V0L1B2LPS-7B equivalent, key selection criteria include clamping voltage at 2A (46V), low-profile footprint (1.08 × 0.68 mm), thermal resistance (500°C/W), RoHS/Green compliance, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode operates as a bidirectional clamping device with symmetrical breakdown behavior above ±26V, triggered by fast-rising ESD transients. Its low 6pF capacitance ensures minimal signal integrity impact on 480 Mbps USB 2.0 or 1080p HDMI interfaces, while the 42V/46V clamping voltages at 1A/2A define its protective window for sensitive 3.3V/5V I/O rails.
The U-DFN1006-2/SWP package integrates sidewall plating for post-reflow optical inspection and uses NiPdAu-plated copper leadframe for reliable solderability. Thermal performance is specified at 250 mW power dissipation on FR-4 with 2oz copper per Diodes' AP02001 layout, supporting operation from –65°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous operating voltage before clamping begins; matches 3.3V/5V logic rail protection requirements |
| Breakdown Voltage (VBR) | 26 V min - Ensures reliable triggering above system operating voltage without false clamping |
| Clamping Voltage (IPP = 2A) | 46 V - Limits transient voltage seen by protected IC during worst-case 8/20µs surge |
| ESD Rating (IEC 61000-4-2) | ±20 kV contact/air - Meets industrial and consumer ESD immunity standards for handheld devices |
| Channel Capacitance | 6 pF typ - Enables use on high-speed interfaces (e.g., USB 2.0, SDIO) without signal degradation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | DO-214AC package (4.5 × 2.7 mm), 400W PPP, 120pF CT, unidirectional | Requires dual-device configuration for bidirectional protection; unsuitable for high-speed interfaces | Select only for cost-sensitive, low-frequency, non-portable applications where size and capacitance are not critical |
| SP1003-02UTG | SOD-523 package (1.3 × 0.85 mm), 30W PPP, 0.6pF CT, bidirectional | Lower peak power rating (30W vs. 90W); insufficient for 2A 8/20µs surge compliance | Prefer for ultra-low-capacitance RF/analog lines; avoid where IEC 61000-4-2 ±20kV must be met with margin |
Compared with SMAJ24A and SP1003-02UTG, D24V0L1B2LPS-7B uniquely balances 90W surge capability, 6pF capacitance, and AEC-Q101 qualification in a 1.08 × 0.68 mm footprint - making it optimal for space-constrained, high-reliability portable and automotive data-line protection.

FAQ
What is the maximum clamping voltage of D24V0L1B2LPS-7B under a 2A ESD surge?
The clamping voltage is 46 V when subjected to a 2A, 8/20 µs transient pulse per IEC 61000-4-2 test conditions. This value is measured at the device terminals with specified PCB layout (AP02001) and defines the peak voltage imposed on protected circuitry during worst-case surge events.
Is D24V0L1B2LPS-7B suitable for protecting USB 3.0 SuperSpeed lines?
No - its 6 pF capacitance and 46 V clamping voltage are optimized for USB 2.0 (480 Mbps) and lower-speed interfaces. USB 3.0 SuperSpeed (5 Gbps) requires sub-0.5 pF capacitance and tighter clamping; this device would degrade signal integrity and fail compliance testing.
Does the "-7B" suffix indicate tape-and-reel packaging and what is the reel quantity?
Yes - the "-7B" suffix denotes 8 mm tape width, 7-inch reel, and 10,000 units per reel. This packaging format is compatible with standard SMT pick-and-place equipment and supports high-volume automated assembly.
How does the sidewall plating in U-DFN1006-2/SWP improve manufacturing yield?
The NiPdAu sidewall plating enables automated optical inspection (AOI) after reflow soldering by providing high-contrast visual identification of solder joint formation and coplanarity. This eliminates reliance on X-ray inspection for fine-pitch, bottom-terminated packages and reduces escape defects in high-mix portable electronics production.
