Product details
Overview
D24V0LA1B2LPQ 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, ±30kV IEC 61000-4-2 ESD rating (contact/air), 15.6pF typical input capacitance, 5A peak pulse current, and AEC-Q101 qualification for automotive use cases such as USB, HDMI, or audio jack interfaces.
For engineers reviewing the D24V0LA1B2LPQ datasheet, D24V0LA1B2LPQ pinout, D24V0LA1B2LPQ application, or D24V0LA1B2LPQ equivalent, key selection criteria include low clamping voltage (42V at 1A), ultra-small X1-DFN1006-2 footprint (1.08 × 0.68 mm), sub-100nA leakage at 24V, and optical-solderable sidewall plating for post-reflow inspection.
Technical Context
This TVS diode operates bidirectionally to clamp both positive and negative transients across its two terminals, with symmetrical breakdown behavior (VBR = 25–33V at 1mA). Its low 15.6pF capacitance ensures minimal signal integrity impact on high-frequency interfaces up to ~1 GHz.
The device uses a planar silicon junction structure in a lead-free, halogen-free molded package. Thermal resistance is 500°C/W (junction-to-ambient), and power derating begins above 25°C ambient per Figure 1 - critical for sustained surge handling in compact enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous working voltage before clamping initiates |
| Breakdown Voltage (VBR) | 25–33 V @ 1mA - Confirmed conduction threshold for ESD event response |
| Clamping Voltage (VCL) | 42 V @ 1A, 46 V @ 5A (8/20µs) - Limits downstream IC stress during surge |
| ESD Rating | ±30 kV contact & air (IEC 61000-4-2) - Full system-level ESD immunity compliance |
| Input Capacitance (CT) | 15.6 pF @ 0V, 1MHz - Enables use on USB 2.0, audio, and other <100MHz signal paths |
| Leakage Current (IRM) | ≤100 nA @ 24V - Prevents battery drain in always-on portable circuits |
| Package | X1-DFN1006-2 - 1.08 × 0.68 mm footprint with optical-solderable sidewalls |
Pinout & Package
Package: X1-DFN1006-2 - ultra-compact, dual-terminal, bottom-side thermal pad-less plastic DFN with NiPdAu-plated copper leadframe and sidewall plating for optical solder-joint inspection.

Applications
| USB 2.0 Data Lines | HDMI Interface Protection |
|---|---|
Use Scenario: ESD protection on D+ and D− lines of smartphone USB ports exposed to frequent plug/unplug events. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector to shunt ±30kV transients before reaching PHY IC. Use Value: 15.6pF capacitance avoids signal rise-time degradation while maintaining full USB 2.0 eye diagram compliance. | Use Scenario: Transient suppression on TMDS clock and data channels in automotive head-unit HDMI outputs. IC Role / Device Role / Timing Role: Low-capacitance TVS placed adjacent to HDMI connector to meet IEC 61000-4-2 and AEC-Q101 reliability requirements. Use Value: 42V clamping at 1A ensures HDMI receiver ICs remain below absolute maximum ratings during hot-plug ESD events. |
| Smartphone Audio Jacks | Automotive Infotainment Touchscreen Flex Cables |
Use Scenario: ESD protection on microphone and headset detection lines in 3.5mm TRRS jacks subject to user-handling discharge. IC Role / Device Role / Timing Role: Single-channel bidirectional TVS bridging tip/ring contacts to ground to suppress contact-discharge surges. Use Value: Sub-100nA leakage prevents false detection in analog audio bias circuits and preserves battery life. | Use Scenario: Surge protection on low-voltage touchscreen controller flex cable routing near display edges in automotive dashboards. IC Role / Device Role / Timing Role: Surface-mount TVS integrated into flex PCB layout to absorb ESD from glove contact or assembly handling. Use Value: X1-DFN1006-2 footprint allows placement within tight bend radius zones without compromising mechanical flexibility. |
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), 3.5x larger footprint, 22pF capacitance | Not suitable for space-constrained mobile PCBs; used in industrial power supplies | Select only when board area permits and higher capacitance is acceptable |
| TPD2E001DRYR | 2-channel, 12pF per line, SOT-563 package, lower 12V standoff | Designed for dual-line protection (e.g., USB D+/D−); not automotive-qualified | Choose for cost-sensitive consumer USB designs where AEC-Q101 is unnecessary |
Compared with SMAJ24A and TPD2E001DRYR, D24V0LA1B2LPQ uniquely combines automotive qualification, optical-solderable construction, and 15.6pF capacitance in a 1.08 × 0.68 mm footprint - making it optimal for next-gen compact, safety-critical portable and automotive interfaces.

FAQ
What is the maximum operating temperature for D24V0LA1B2LPQ?
The device supports continuous operation from –65°C to +150°C. Its thermal resistance (RθJA) is 500°C/W on standard FR-4 with recommended pad layout, so derating is required above 25°C ambient to maintain safe junction temperature during surge events.
Does D24V0LA1B2LPQ require orientation during PCB placement?
No. As a bidirectional TVS diode in a symmetric X1-DFN1006-2 package, D24V0LA1B2LPQ has no polarity marking and functions identically regardless of rotational orientation - simplifying automated placement and reducing assembly errors.
Can D24V0LA1B2LPQ protect against IEC 61000-4-5 lightning surges?
No. It is rated for IEC 61000-4-2 ESD only (±30kV). For IEC 61000-4-5 (lightning-induced surges), a higher-power TVS like SMAJ24A or dedicated surge protector IC is required - D24V0LA1B2LPQ's 230W peak pulse power is insufficient for 4kV/2Ω combination wave testing.
Is the "MH" marking on the device surface traceable to a specific lot or wafer?
"MH" is the product type code per Diodes' marking standard (not a date or lot code). Full traceability - including wafer lot, assembly batch, and test data - is provided via Aetrix's certified material documentation upon request for automotive PPAP submissions.
