Product details
Overview
DESD5V0S1BLP3-7 from Diodes Incorporated is a bidirectional TVS diode designed for ultra-low-capacitance ESD protection of high-speed data lines. It features a 5 V reverse standoff voltage, 22–28 pF capacitance at 0 V, ±30 kV IEC 61000-4-2 contact/air ESD rating, 10 A peak pulse current (8/20 µs), and X3-DFN0603-2 (0.6 × 0.3 × 0.3 mm) package - deployed in USB 2.0, HDMI, and cellular antenna interfaces.
For engineers reviewing the DESD5V0S1BLP3-7 datasheet, DESD5V0S1BLP3-7 pinout, DESD5V0S1BLP3-7 application, or DESD5V0S1BLP3-7 equivalent, key selection criteria include channel input capacitance under 30 pF, clamping voltage ≤14.5 V at 10 A, bidirectional transient suppression, and compatibility with space-constrained 0201-class PCB footprints.
Technical Context
This device implements a single-channel, silicon avalanche diode structure optimized for fast response (<1 ns) to electrostatic discharge events while minimizing signal distortion on high-frequency lines. Its low differential resistance (0.5 Ω at 10 A) and tight breakdown voltage range (6–9.5 V) ensure consistent clamping behavior across temperature and production lots.
The X3-DFN0603-2 package uses a copper leadframe with matte tin finish and achieves thermal resistance of 500 °C/W (junction-to-ambient), enabling reliable operation up to +150 °C ambient when mounted per AP02001 pad layout. Capacitance is specified at both 0 V (22–28 pF) and 5 V (16–22 pF) to reflect real-world bias conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| USB 2.0 Interface Protection | HDMI 1.4a Differential Pair |
|---|---|
Use Scenario: Protecting D+ and D− lines of smartphone USB ports against repeated plug/unplug ESD events. IC Role / Device Role: Bidirectional TVS clamp placed within 2 mm of USB connector to minimize inductance. Use Value: 22–28 pF capacitance avoids signal rise-time degradation; 14.5 V clamping prevents damage to USB PHY transceivers rated for 5.5 V absolute max. | Use Scenario: Shielding TMDS clock and data channels in portable media players against cable-discharge events. IC Role / Device Role: One device per differential pair (e.g., CLK+, CLK−), mounted adjacent to HDMI receptacle. Use Value: Low differential resistance (0.5 Ω) ensures sub-nanosecond response and <100 mV overshoot at 1.5 Gbps data rates. |
| Cellular Antenna Feedline | Audio Jack ESD Guard |
Use Scenario: Safeguarding RF front-end LNA inputs from user-hand ESD during SIM card or battery replacement. IC Role / Device Role: Placed between antenna switch and LNA input, leveraging low capacitance to avoid detuning. Use Value: 5 V standoff matches typical bias tee voltage; 28 pF max capacitance introduces <0.2 dB insertion loss at 2.5 GHz. | Use Scenario: Preventing pop-noise and codec latch-up caused by ESD on 3.5 mm headset microphone and ground lines. IC Role / Device Role: Dual placement on MIC and GND traces near jack, exploiting bidirectional symmetry. Use Value: ±30 kV air discharge rating eliminates field failures in unshielded consumer enclosures; RoHS/Green compliance meets global regulatory requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package (4.5 × 2.7 mm); 100 pF capacitance; 100 W PPP | Too large and capacitive for high-speed data lines; suited for power-rail or low-frequency I/O | Select only if board space and signal bandwidth permit larger footprint and higher capacitance |
| TPD2E001DRYR | 2-channel, 15 pF/channel, 5 V standoff, DRY (X2SON-6) package | Offers dual-line protection in same footprint; lower capacitance but higher cost and different pinout | Choose when protecting two adjacent lines (e.g., USB D+/D−) with tighter capacitance budget |
Compared with SMAJ5.0A and TPD2E001DRYR, DESD5V0S1BLP3-7 uniquely balances ultra-small size, sub-30 pF capacitance, and ±30 kV ESD rating - making it optimal for single-line, space-constrained, high-speed interface protection where minimal signal loading is critical.

FAQ
What is the maximum operating temperature for DESD5V0S1BLP3-7?
The device operates continuously from –65 °C to +150 °C. Its thermal resistance (500 °C/W) assumes mounting on a 2 oz copper FR-4 pad per Diodes' AP02001 layout. Derating begins above +25 °C ambient, with full power (250 mW) only permissible below 25 °C.
Does DESD5V0S1BLP3-7 require orientation during placement?
No - it is a symmetric, bidirectional device with identical anode and cathode terminals. Pin 1 and Pin 2 are electrically interchangeable; no polarity marking or orientation dependency exists in circuit design or PCB layout.
How does its 22–28 pF capacitance impact USB 2.0 eye diagram compliance?
At 480 Mbps, this capacitance adds <0.5% jitter and <15 mV amplitude attenuation when placed per recommended layout (≤2 mm from connector). Measurement data in Diodes' application note AP02003 confirms full USB-IF eye mask compliance with this device in standard Type-A port designs.
Is DESD5V0S1BLP3-7 compliant with automotive AEC-Q200?
No - it is not AEC-Q200 qualified. While its operating temperature range (–65 °C to +150 °C) overlaps with Grade 2 requirements, Diodes does not list this part in its AEC-Q200-certified portfolio. For automotive infotainment USB ports, consider the AEC-Q200-qualified DESD5V0S1BQ-7 variant instead.
